45 best health tips ever

We've done the legwork for you and here they are: the 45 best health tips. Give yourself a boost.

We've done the legwork for you and here they are: the 45 best health tips. Make that 46 - taking the time to read this tops the list.

1. Copy your kitty: Learn to do stretching exercises when you wake up. It boosts circulation and digestion, and eases back pain.

2. Don’t skip breakfast. Studies show that eating a proper breakfast is one of the most positive things you can do if you are trying to lose weight. Breakfast skippers tend to gain weight. A balanced breakfast includes fresh fruit or fruit juice, a high-fibre breakfast cereal, low-fat milk or yoghurt, wholewheat toast, and a boiled egg.

3. Brush up on hygiene. Many people don't know how to brush their teeth properly. Improper brushing can cause as much damage to the teeth and gums as not brushing at all. Lots of people don’t brush for long enough, don’t floss and don’t see a dentist regularly. Hold your toothbrush in the same way that would hold a pencil, and brush for at least two minutes.

This includes brushing the teeth, the junction of the teeth and gums, the tongue and the roof of the mouth. And you don't need a fancy, angled toothbrush – just a sturdy, soft-bristled one that you replace each month.

4. Neurobics for your mind. Get your brain fizzing with energy. American researchers coined the term ‘neurobics’ for tasks which activate the brain's own biochemical pathways and to bring new pathways online that can help to strengthen or preserve brain circuits.

Brush your teeth with your ‘other’ hand, take a new route to work or choose your clothes based on sense of touch rather than sight. People with mental agility tend to have lower rates of Alzheimer's disease and age-related mental decline.

5. Get what you give! Always giving and never taking? This is the short road to compassion fatigue. Give to yourself and receive from others, otherwise you’ll get to a point where you have nothing left to give. And hey, if you can’t receive from others, how can you expect them to receive from you?

6. Get spiritual. A study conducted by the formidably sober and scientific Harvard University found that patients who were prayed for recovered quicker than those who weren’t, even if they weren’t aware of the prayer.

7. Get smelly. Garlic, onions, spring onions and leeks all contain stuff that’s good for you. A study at the Child’s Health Institute in Cape Town found that eating raw garlic helped fight serious childhood infections. Heat destroys these properties, so eat yours raw, wash it down with fruit juice or, if you’re a sissy, have it in tablet form.

8. Knock one back. A glass of red wine a day is good for you. A number of studies have found this, but a recent one found that the polyphenols (a type of antioxidant) in green tea, red wine and olives may also help protect you against breast cancer. It’s thought that the antioxidants help protect you from environmental carcinogens such as passive tobacco smoke.

9. Bone up daily. Get your daily calcium by popping a tab, chugging milk or eating yoghurt. It’ll keep your bones strong. Remember that your bone density declines after the age of 30. You need at least 200 milligrams daily, which you should combine with magnesium, or it simply won’t be absorbed.

10. Berries for your belly. Blueberries, strawberries and raspberries contain plant nutrients known as anthocyanidins, which are powerful antioxidants. Blueberries rival grapes in concentrations of resveratrol – the antioxidant compound found in red wine that has assumed near mythological proportions. Resveratrol is believed to help protect against heart disease and cancer.

11. Curry favour. Hot, spicy foods containing chillies or cayenne pepper trigger endorphins, the feel-good hormones. Endorphins have a powerful, almost narcotic, effect and make you feel good after exercising. But go easy on the lamb, pork and mutton and the high-fat, creamy dishes served in many Indian restaurants.

12. Cut out herbs before ops. Some herbal supplements – from the popular St John's Wort and ginkgo biloba to garlic, ginger, ginseng and feverfew – can cause increased bleeding during surgery, warn surgeons. It may be wise to stop taking all medication, including herbal supplements, at least two weeks before surgery, and inform your surgeon about your herbal use.

13. I say tomato. Tomato is a superstar in the fruit and veggie pantheon. Tomatoes contain lycopene, a powerful cancer fighter. They’re also rich in vitamin C. The good news is that cooked tomatoes are also nutritious, so use them in pasta, soups and casseroles, as well as in salads.

The British Thoracic Society says that tomatoes and apples can reduce your risk of asthma and chronic lung diseases. Both contain the antioxidant quercetin. To enjoy the benefits, eat five apples a week or a tomato every other day.

14. Eat your stress away. Prevent low blood sugar as it stresses you out. Eat regular and small healthy meals and keep fruit and veggies handy. Herbal teas will also soothe your frazzled nerves.

Eating unrefined carbohydrates, nuts and bananas boosts the formation of serotonin, another feel-good drug. Small amounts of protein containing the amino acid tryptamine can give you a boost when stress tires you out.

15. Load up on vitamin C.We need at least 90 mg of vitamin C per day and the best way to get this is by eating at least five servings of fresh fruit and vegetables every day. So hit the oranges and guavas!

16. No folly in folic acid. Folic acid should be taken regularly by all pregnant mums and people with a low immunity to disease. Folic acid prevents spina bifida in unborn babies and can play a role in cancer prevention. It is found in green leafy vegetables, liver, fruit and bran.

17. A for Away. This vitamin, and beta carotene, help to boost immunity against disease. It also assists in the healing process of diseases such as measles and is recommended by the WHO. Good natural sources of vitamin A are kidneys, liver, dairy products, green and yellow vegetables, pawpaw, mangoes, chilli pepper, red sorrel and red palm oil.

18. Pure water. Don’t have soft drinks or energy drinks while you're exercising. Stay properly hydrated by drinking enough water during your workout (just don't overdo things, as drinking too much water can also be dangerous).

While you might need energy drinks for long-distance running, in shorter exercise sessions in the gym, your body will burn the glucose from the soft drink first, before starting to burn body fat. Same goes for eating sweets.

19. GI, Jane. Carbohydrates with a high glycaemic index, such as bread, sugar, honey and grain-based food will give instant energy and accelerate your metabolism. If you’re trying to burn fat, stick to beans, rice, pasta, lentils, peas, soya beans and oat bran, all of which have a low GI count.

20. Mindful living. You've probably heard the old adage that life's too short to stuff a mushroom. But perhaps you should consider the opposite: that life's simply too short NOT to focus on the simple tasks. By slowing down and concentrating on basic things, you'll clear your mind of everything that worries you.

Really concentrate on sensations and experiences again: observe the rough texture of a strawberry's skin as you touch it, and taste the sweet-sour juice as you bite into the fruit; when your partner strokes your hand, pay careful attention to the sensation on your skin; and learn to really focus on simple tasks while doing them, whether it's flowering plants or ironing your clothes.


21. The secret of stretching. When you stretch, ease your body into position until you feel the stretch and hold it for about 25 seconds. Breathe deeply to help your body move oxygen-rich blood to those sore muscles. Don't bounce or force yourself into an uncomfortable position.

22. Do your weights workout first. Experts say weight training should be done first, because it's a higher intensity exercise compared to cardio. Your body is better able to handle weight training early in the workout because you're fresh and you have the energy you need to work it.

Conversely, cardiovascular exercise should be the last thing you do at the gym, because it helps your body recover by increasing blood flow to the muscles, and flushing out lactic acid, which builds up in the muscles while you're weight training. It’s the lactic acid that makes your muscles feel stiff and sore.

23. Burn fat during intervals. To improve your fitness quickly and lose weight, harness the joys of interval training. Set the treadmill or step machine on the interval programme, where your speed and workload varies from minute to minute. Build up gradually, every minute and return to the starting speed. Repeat this routine. Not only will it be less monotonous, but you can train for a shorter time and achieve greater results.

24. Your dirtiest foot forward. If your ankles, knees, and hips ache from running on pavement, head for the dirt. Soft trails or graded roads are a lot easier on your joints than the hard stuff. Also, dirt surfaces tend to be uneven, forcing you to slow down a bit and focus on where to put your feet – great for agility and concentration.

25. Burn the boredom, blast the lard. Rev up your metabolism by alternating your speed and intensity during aerobic workouts. Not only should you alternate your routine to prevent burnout or boredom, but to give your body a jolt.

If you normally walk at 6.5km/h on the treadmill or take 15 minutes to walk a km, up the pace by going at 8km/h for a minute or so during your workout. Do this every five minutes or so. Each time you work out, increase your bouts of speed in small increments.

26. Cool off without a beer. Don’t eat carbohydrates for at least an hour after exercise. This will force your body to break down body fat, rather than using the food you ingest. Stick to fruit and fluids during that hour, but avoid beer.

27. ‘Okay, now do 100 of those’. Instead of flailing away at gym, enlist the help – even temporarily – of a personal trainer. Make sure you learn to breathe properly and to do the exercises the right way. You’ll get more of a workout while spending less time at the gym.

28. Stop fuming. Don’t smoke and if you smoke already, do everything in your power to quit. Don’t buy into that my-granny-smoked-and-lived-to-be-90 crud – not even the tobacco giants believe it. Apart from the well-known risks of heart disease and cancer, orthopaedic surgeons have found that smoking accelerates bone density loss and constricts blood flow. So you could live to be a 90-year-old amputee who smells of stale tobacco smoke. Unsexy.

29. Ask about Mad Aunt Edith. Find out your family history. You need to know if there are any inherited diseases prowling your gene pool. According to the Mayo Clinic, USA, finding out what your grandparents died of can provide useful – even lifesaving – information about what’s in store for you. And be candid, not coy: 25% of the children of alcoholics become alcoholics themselves.

30. Do self-checks. Do regular self-examinations of your breasts. Most partners are more than happy to help, not just because breast cancer is the most common cancer among SA women. The best time to examine your breasts is in the week after your period.

31. My smear campaign. Have a pap smear once a year. Not on our list of favourite things, but it’s vital. Cervical cancer kills 200 000 women a year and it’s the most prevalent form of cancer among black women, affecting more than 30 percent.

But the chances of survival are nearly 100 percent if it’s detected early. Be particularly careful if you became sexually active at an early age, have had multiple sex partners or smoke.

32. Understand hormones. Recent research suggests that short-term (less than five years) use of HRT is not associated with an increase in the risk of breast cancer, but that using it for more than ten years might be. Breast cancer is detected earlier in women using HRT, as they are more alert to the disease than other women.

32. Beat the sneezes. There are more than 240 allergens, some rare and others very common. If you’re a sneezer due to pollen: close your car’s windows while driving, rather switch on the internal fan (drawing in air from the outside), and avoid being outdoors between 5am and 10 am when pollen counts are at their highest; stick to holidays in areas with low pollen counts, such as the seaside and stay away from freshly cut grass.

33. Doggone. If you’re allergic to your cat, dog, budgie or pet piglet, stop suffering the ravages of animal dander: Install an air filter in your home.

Keep your pet outside as much as possible and brush him outside of the home to remove loose hair and other allergens. Better yet, ask someone else to do so.

34. Asthma-friendly sports. Swimming is the most asthma-friendly sport of all, but cycling, canoeing, fishing, sailing and walking are also good, according to the experts.

Asthma need not hinder peak performance in sport. 1% of the US Olympic team were asthmatics – and between them they won 41 medals.

35. Deep heat. Sun rays can burn even through thick glass, and under water. Up to 35% of UVB rays and 85% of UVA rays penetrate thick glass, while 50% of UVB rays and 75% of UVA rays penetrate a meter of water and wet cotton clothing.

Which means you’ll need sunscreen while driving your car on holiday, and water resistant block if you’re swimming.

36. Fragrant ageing. Stay away from perfumed or flavoured suntan lotions which smell of coconut oil or orange if you want your skin to stay young. These lotions contain psoralen, which speeds up the ageing process. Rather use a fake-tan lotion. Avoid sun beds, which are as bad as the sun itself.

37. Sunscreen can be a smokescreen. Sunscreen is unlikely to stop you from being sunburned, or to reduce your risk of developing skin cancer. That’s because most people don’t apply it properly, and stay in the sun too long.

The solution? Slather on sunscreen daily and reapply it often, especially if you’ve been in the water. How much? At least enough to fill a shot glass.

38. Laugh and cry. Having a good sob is reputed to be good for you. So is laughter, which has been shown to help heal bodies, as well as broken hearts. Studies in Japan indicate that laughter boosts the immune system and helps the body shake off allergic reactions.

39. It ain’t over till it’s over. End relationships that no longer work for you, as you could be spending time in a dead end. Rather head for more meaningful things. You could be missing opportunities while you’re stuck in a meaningless rut, trying to breathe life into something that is long gone.

40. Strong people go for help. Ask for assistance. Gnashing your teeth in the dark will not get you extra brownie points. It is a sign of strength to ask for assistance and people will respect you for it. If there is a relationship problem, the one who refuses to go for help is usually the one with whom the problem lies to begin with.

41. Save steamy scenes for the bedroom. Showering or bathing in water that’s too hot will dry out your skin and cause it to age prematurely. Warm water is much better.

Apply moisturiser while your skin is still damp – it’ll be absorbed more easily. Adding a little olive oil to your bath with help keep your skin moisturised too.

42. Here’s the rub. Improve your circulation and help your lymph glands to drain by the way you towel off. Helping your lymph glands function can help prevent them becoming infected.

When drying off your limbs and torso, brush towards the groin on your legs and towards the armpits on your upper body. You can do the same during gentle massage with your partner.

43. Sugar-coated. More than three million South Africans suffer from type 2 diabetes, and the incidence is increasing – with new patients getting younger. New studies show this type of diabetes is often part of a metabolic syndrome (X Syndrome), which includes high blood pressure and other risk factors for heart disease.

More than 80% of type 2 diabetics die of heart disease, so make sure you control your glucose levels, and watch your blood pressure and cholesterol counts.

44. Relax, it’s only sex. Stress and sex make bad bedfellows, it seems. A US survey showed that stress, kids and work are main factors to dampen libido. With the advent of technology that allows us to work from home, the lines between our jobs and our personal lives have become blurred.

People work longer hours, commutes are longer and work pervades all aspects of our lives, including our sexual relationships. Put nooky and intimacy on the agenda, just like everything else.

45. Good night, sweetheart. Rest heals the body and has been shown to lessen the risk of heart trouble and psychological problems.

Health advice: Eat less red meat to reduce cancer risk

People should cut back on red and processed meat to reduce their risk of getting cancer, the government says.

New advice recommends eating no more than 70g a day - equivalent to three rashers of bacon or two sausages.
Experts say thousands of bowel cancer deaths could be prevented every year if people kept to the new limits.

Advisers to the Department of Health in England say the restrictions would not put people at risk of iron deficiencies.
Bowel Cancer is the third most common cancer in the UK - about 36,000 people are diagnosed every year, and 16,500 die.

Eating 100 to 120g of red and processed meat a day - things like salami, ham and sausages - increases the risk of developing the condition by 20 to 30%, according to studies.



But some commentators have questioned whether reducing red meat consumption would put people at greater risk of iron deficiency; red meat is a very good source of iron.
Iron deficiency causes anaemia, which leads to tiredness and dizzy spells, can affect brain development and result in behavioural problems.

'Occasional steak'

But a report from the Scientific Advisory Committee on Nutrition says if adults cut back to 70g of red meat a day, there would not be much impact on the number of people with low iron intake.

"Red meat can be part of a healthy balanced diet," said the interim Chief Medical Officer for England, Professor Sally Davies, "but people who eat a lot should consider cutting down."
"The occasional steak or extra few slices of lamb is fine, but regularly eating a lot could increase your risk of bowel cancer."
The charity Beating Bowel Cancer welcomed the report.
"A diet high in red and processed meat may increase your risk of developing bowel cancer," said chief executive Mark Flannagan. "But the good news is that red meat can still be enjoyed in moderation."

Some experts, though, say the advice should distinguish between red and processed meat, which is thought to carry a higher bowel cancer risk.

The World Cancer Research Fund advises avoiding processed meat altogether.
"We would suggest that people following this new report's guidelines should try and make sure as little as possible of their 70g per day is processed," said Dr Rachel Thompson, deputy head of science for the fund.

Weightlifting 'reduces men's diabetes risk'

"Pumping weights five times a week can reduce the risk of type 2 diabetes by a third," The Daily Telegraph has reported.
The news is based on the results of a large US study which found that men who performed weight training reduced their risk of developing type 2 diabetes.



Previous research has shown that regular moderate or vigorous physical activity for at least 30 minutes a day reduces risk of type 2 diabetes. The authors of the study also reported that other studies have shown that resistance training can improve blood sugar control in people with diabetes. This is the first significant piece of research that has also found a link between weight training and a reduced risk of actually developing diabetes.

This study found that at least 150 minutes of weight training a week reduced the risk of developing type 2 diabetes by just over one third (34%). Performing at least 150 minutes of aerobic exercise a week (such as brisk walking, jogging, running, cycling, swimming, tennis, squash and rowing) reduced risk to a slightly greater extent (52%). The greatest risk reduction was observed when performing a combination of both weight training and aerobic exercise (59%).

Regular exercise, in addition to other healthy lifestyle behaviours, is the best way to reduce the risk of many chronic diseases, including type 2 diabetes. This study supports general health advice, finding that weight training or aerobic exercise reduced the risk of type 2 diabetes in professional men. Weightlifting may be a useful exercise addition, or alternative, for people who have difficulty in performing aerobic exercise, but as with all forms of exercise it is advisable to exercise within your own limits. The key advice is to take regular exercise – weightlifting may not be the best workout for everyone.


Where did the story come from?

The study was carried out by researchers from Harvard School of Public Health, Harvard Medical School, Brigham and Women’s Hospital, the University of Southern Denmark and the Norwegian School of Sport Sciences. It was funded by the US National Institutes of Health. The study was published in the peer-reviewed journal, Archives of Internal Medicine.
This story was reported in The Daily Telegraph and the Daily Mail. The Mail’s headline made it clear that the study had only been performed in men.
The coverage of the report in both papers was accurate

What kind of research was this?

This was an analysis of data collected from a prospective cohort study of professional men in the US: the Health Professionals Follow-up Study (HPFS). This particular analysis aimed to determine whether there was a link between weight training and the risk of type 2 diabetes. This is the ideal study design to answer this question. However, cohort studies cannot show that weight training is the cause of any change in risk of type 2 diabetes, as researchers cannot exclude the possibility that other factors (called confounders) are responsible for any link seen.
In particular, as the HPFS was not set up to specifically to answer this study question, it is possible that other relevant factors may not have been considered.

What did the research involve?

This study used the HPFS, an ongoing cohort study, which followed up male health professionals aged between 40 and 75 in 1986. Information on weightlifting and other forms of exercise had been reported from 1990 onwards. Therefore, for the purpose of this particular study, the researchers excluded men who in 1990 had diabetes, cancer, angina or past heart attack, coronary artery bypass graft, other heart conditions, stroke or pulmonary embolism.
This left 32,002 men who, between 1990 and 2008, completed a questionnaire every two years on diseases and personal and lifestyle characteristics, such as height, weight, smoking status, diet and physical activity. Weekly time spent on weight training and aerobic exercise (including jogging, bicycling, swimming, tennis and calisthenics) were obtained.
The development of type 2 diabetes was also assessed on the questionnaires, and men who reported a diagnosis of type 2 diabetes were asked to complete supplementary questionnaires so that the diagnosis could be confirmed. The diagnosis of diabetes was confirmed by medical record review in a subgroup of participants (97% of the participants had their diabetes confirmed). Deaths were also monitored.

The researchers looked to see if there was an association between weight training or aerobic exercise and the development of type 2 diabetes. When looking to see if there was a link, they tried to adjust for other factors that may explain the association, including:
age
smoking

alcohol consumption

coffee intake

ethnicity

family history of diabetes

diet (including total intake of energy, trans-fat, polyunsaturated fat to saturated fat ratio, cereal fibre, whole grain and glycaemic load)


What were the basic results?


The researchers found that there were 2,278 new cases of type 2 diabetes follow-up, and that:
More time spent on weight training or on aerobic exercise was associated with decreased risk of type 2 diabetes (a dose-response relationship).
Performing weight training only for at least 150 minutes a week was associated with a statistically significant 34% reduced risk of type 2 diabetes, compared with doing no weight training (after adjusting for aerobic exercise, other physical activity of at least moderate intensity and television viewing).
Performing aerobic exercise for at least 150 minutes a week was associated with a statistically significant 52% lower risk of type 2 diabetes, compared with doing no aerobic exercise (after adjusting for weight training, other physical activity of at least moderate intensity and television viewing).
Men who did both aerobic exercise and weight training for at least 150 minutes a week had a 59% reduction in risk of type 2 diabetes, which was the greatest reduction in risk (when compared with doing no aerobic exercise or physical activity).
How did the researchers interpret the results?

The researchers concluded that weight training was associated with a significantly lower risk of type 2 diabetes, and that this association is independent of aerobic exercise. They concluded that their results support that “weight training serves as an important alternative for individuals who have difficulty adhering to aerobic exercise, but the combination of weight training with aerobic exercise confers an even greater benefit”.
Conclusion

This cohort study found that weight training is associated with a reduced risk of type 2 diabetes, with increased training associated with reduced risk in male health professionals. This association was independent of aerobic exercise. However, although the study has focused on weightlifting, performing aerobic exercise was actually associated with greater risk reduction than weightlifting. The greatest reduction in risk was seen in men who performed both weight training and aerobic exercise for 150 minutes a week.

This study has both strengths and weaknesses. The strengths include the large number of participants, the long follow-up and the fact that both physical activity and other factors that may explain the association (such as diet and alcohol consumption) were assessed regularly. However, the data was collected by self-reported questionnaires, which may be subject to reporting bias. The researchers also did not collect data on the type or intensity of the weight training.
Only male health professionals aged between 40 and 75 years old at baseline were included, and most of the men were white. This means that the findings may not apply to women, younger men or other ethnic groups.

The latter factor may be particularly important as rates of type 2 diabetes can vary significantly between ethnic groups. For example, the condition is more common in those of South Asian, African-Caribbean or Middle Eastern descent.

Finally, the researchers cannot exclude the possibility that the association seen may be explained by another factor that they have not controlled for. The fact that the Health Professionals Follow-up Study was not set up specifically to study whether weightlifting influences risk of diabetes may further increase the possibility that other relevant factors have not been taken into account.

In conclusion, this study supports general health advice by finding that weight training or aerobic exercise reduces the risk of type 2 diabetes in professional men. Weight training may be a useful exercise addition, or alternative, for people who have difficulties in performing aerobic exercise.
However, further studies are required to confirm the association between weight training and diabetes, to see whether it also applies to women and to examine whether the duration, type and intensity of weight training make any difference.

Two-and-a-half hours of weight training a week is a big commitment and shouldn’t detract from other forms of exercise. It is also important to be aware that, as with all forms of exercise, it is advisable to exercise within your own limits. The key advice is to take regular exercise – weightlifting may not be the best workout for everyone.

Fish pedicure risk 'very low'

“Trendy fish pedicures could spread HIV and hepatitis C,” The Sun has today reported. Its front-page story said that officials have raised an “alert” over the treatment, popular in beauty spas, where tiny fish are used to nibble away areas of hard foot skin.



Although The Sun has been carping on about warnings and alerts, the newspaper seems to have overestimated the scale of the risk, which health experts have described as being “extremely low”. Rather than being an alert, the news is based on a report by the Health Protection Agency that has set out good practice for so-called ‘fish spas’ that offer the service.
While the report did acknowledge that the risk of infections could not be completely ruled out, it is important to view this in context and not be reeled in by fishy headlines.
What exactly is a fish pedicure?

A fish pedicure is a beauty treatment that uses dozens of tiny fish to nibble away dead and hardened skin from the feet. During a session a person immerses their feet in a tank of warm water and lets the minute, toothless Garra rufa fish nibble away for around 15 to 30 minutes. The fish are said only to eat dead skin, although there are some anecdotal reports that they can break the skin if they nibble too deep.
Fish pedicures have long been used as beauty treatments in Turkey and the Far East, but have only recently been introduced to this country. In the few years since the first UK ‘fish spa’ opened the treatment’s popularity has rocketed due to celebrity endorsements and high-profile press coverage. The HPA says that, as of spring 2011, it is aware of 279 in operation (although there are likely to be many more).
A small number of spas may also be using other species of fish to perform pedicures, such as Chin chin fish. However, the HPA says that these should not be used as they develop teeth when they get older, and may therefore present a greater risk to public health.
What did the report examine?

The report examined a number of issues relating to fish pedicures, including:
potential ways infections might occur
the risk of catching blood-borne viruses, including HIV and hepatitis
the risk of bacterial infections
the risk of catching parasites, such as fluke worms
the risk of transmitting conditions, such as athlete’s foot and verrucas
procedures that might reduce any health risks
The report is based on consultations with experts and professional bodies within the fields of public health, aquaculture, health and safety, and animal welfare.
What did the report find?

The report considered three main ways that a person might catch an infection:
from a fish or a fish tank
from tank water
from another person via surfaces, such as floors
Within these areas they considered the different types of infections that might occur.
Blood-borne viruses
Viruses such as HIV and hepatitis are carried in the blood and, in theory, could be transmitted through tank water if someone with a cut or abrasion were to use a tank containing traces of blood from an infected person with cuts.
However, there is only anecdotal evidence that Garra rufa fish can draw blood, and the HPA says that any blood-borne viruses they come into contact with are unlikely to stay on the surface of their mouths and lead to infection. Any blood entering the tank is likely to be diluted by the volume of water used.
While transmission through this method cannot be completely ruled out, the HPA says the risk of catching a blood-borne virus in this way is extremely low. Further to this, the HPA is recommending that the fish spas check clients for cuts and abrasions both before and after their session.
Parasites
Fish-borne parasites, such as tapeworms and flukes, can be caught by humans if they eat undercooked fish. However, the HPA says that there is no evidence that these can be caught from a fish pedicure as this would require ingestion of the fish or the water.
Bacterial infections
The report looked at a number of specific harmful bacteria, including those that cause salmonella and legionnaires’ disease. Generally, these were deemed to be of low risk as they would not be ingested or would need broken skin to cause infection.
However, certain bacteria were identified as posing a greater risk of infection. For example, Staphylococcus aureus might infect people’s skin if they have eczema or psoriasis. Also, a type of bacteria called Mycobacterium marinum, which is associated with fish tanks and non-chlorinated swimming pools, could cause boils if transferred into broken skin.
Fungal infections such as verrucas and athlete’s foot
Fungi are known to survive on inanimate surfaces for prolonged periods and could, therefore, be passed on by infected clients walking around barefoot. However, the HPA points out that this route of transmission is not unique to fish spas.
So are fish pedicures safe?

The Health Protection Agency says that “on the basis of the evidence identified and the consensus view of experts, the risk of infection as a result of a fish pedicure is likely to be very low”. The agency outlines some groups who are not recommended to have fish pedicures due to increased risk of infection, such as people with diabetes or compromised immune systems.

The HPA also specifically addresses the possibility of transmitting blood-borne viruses such as HIV and hepatitis. The agency says that, in theory, transmission could occur if infected blood from one person got into an open wound on another person using the same tank, although, once again, the risk is “extremely low”. In part, the risk would be minimised due to factors such as the diluting action of the water and the fact that infected blood would be unlikely to stay on the fishes’ mouths.

However, the agency does say that the risk of infections cannot be completely excluded and, in order to further reduce this risk, they have drawn up a list of recommendations for fish spas.
What recommendations does the HPA make?

The HPA has made extensive recommendations on how fish spas can further reduce the risk of infections. Below are some of the major ones.

Groups not recommended to have a fish pedicure

The agency also says fish pedicures are not recommended for people that may increase the risk of infection or pose an infection risk to other clients. This includes people who:
have had their legs waxed or shaved in the previous 24 hours (they may have tiny cuts that increase infection risk)
have any open cuts, wounds, abrasions or broken skin on the feet or lower legs
have an infection on the feet (including athlete’s foot or a verruca)
have psoriasis, eczema or dermatitis affecting the feet or lower legs
are diabetic (which leads to increased risk of infection)
have a blood-borne virus such as hepatitis B, hepatitis C or HIV
have an immune deficiency due to illness or medication
have bleeding disorders or take anticoagulant medication (for example, heparin or warfarin)
Safety procedures for fish spas
The HPA recommends that:
Clients should be provided with medical information on any potential risk, including specific guidance on conditions that raise infection risk.

Clients should have their feet examined both before and after treatment to make sure they are free from cuts and infections. Staff should log that these checks have been performed.
Feet should be thoroughly washed and rinsed before a pedicure to minimise the number of micro-organisms transferred into the tank.

If there is evidence that bleeding has occurred during a session the tank should be drained and cleaned thoroughly. The HPA has drawn up thorough guidelines on how to disinfect tanks in a fish-friendly way. After 48 hours in a holding tank the fish can be reused.
Clients should be told to seek advice from their GP if they experience any adverse effects.

New weight advice for pregnancy

Many newspapers have reported on new official guidelines for how women can manage their weight before, during and after pregnancy. The advice comes from the National Institute for Health and Clinical Excellence (NICE).



The importance of the guidelines is borne out by figures suggesting that more pregnant women than ever are overweight or obese. The Guardian suggests that, “15-20% of women getting pregnant are overweight or obese”. The Daily Mail puts the number higher, saying that “almost half of expectant mothers are overweight or obese”. It goes on to spell out the dangers of being obese or overweight during pregnancy, which include “fatal health conditions such as blood clots, pre-eclampsia, miscarriages and stillbirths”.

The newspapers also dispel the myth that women should eat for two during pregnancy. Further advice reported in the press includes taking at least 30 minutes of moderate exercise per day during pregnancy, and that pregnant women should avoid dieting and only need to have an extra 200 calories a day in the last three months of their pregnancy.

These guidelines are published by NICE, and are evidence-based. They are designed so that doctors can give women up-to-date reliable advice to follow to maintain a healthy weight before, during and after their pregnancy.

Where did the advice come from?

The advice has just been published by the National Institute for Health and Clinical Excellence (NICE) as part of its public health programme. NICE produces guidance on the promotion of good health and the prevention of ill health for those working in the NHS, local authorities and the wider public and voluntary sector.

What are the health risks of being obese during pregnancy?

Women who are obese (with a BMI over 30) when they become pregnant face an increased risk of complications such as diabetes, miscarriage, pre-eclampsia, blood clots and death. Obese women are also more likely to have an induced or longer labour, post-delivery bleeding and slower wound healing after delivery. They also tend to be less mobile, which can result in a need for more pain-relieving drugs during labour. These can be difficult to administer in obese women, resulting in a greater need for general anaesthesia with its associated risks.

For women who have gained weight between pregnancies, even a relatively small gain of 1-2 BMI units can increase the risk of high blood pressure or diabetes during their next pregnancy and may also increase the chance of giving birth to a large baby.


What sort of diet does NICE recommend?

NICE offers the following dietary advice to help women to achieve and maintain a healthy weight:
Base meals on starchy foods (such as potatoes, bread, rice and pasta), choosing wholegrain where possible.
Eat foods rich in fibre.
Eat at least five portions of fruit and vegetables per day in place of foods higher in fat or calories.
Eat as little as possible of fried foods, and drinks and confectionery high in sugars and fats.
Eat breakfast.
Watch portion size of meals and how often they are eaten.
What should women aim to weigh before getting pregnant?

Women with a BMI of 30 or more can achieve significant health benefits if they lose between 5-10% of their weight. Further weight loss to achieve a BMI within the healthy range of 18.5 and 24.9 is encouraged.
What about weight during pregnancy?

The amount of weight a woman may gain in pregnancy varies a great deal, and only some of it is due to increased body fat. The unborn child, placenta, amniotic fluid and increases in maternal blood and fluid volume all contribute to weight gain during pregnancy.

Dieting during pregnancy is not recommended as it may harm the health of the child.
There is no need to ‘eat for two’ or drink full-fat milk (as opposed to lower-fat milk). Energy needs do not change in the first six months of pregnancy. Only in the last three months do a woman’s energy needs increase by around 200 calories per day.

Moderate-intensity physical activity will not harm the mother or baby. At least 30 minutes per day of moderate intensity activity is recommended. This can include activities such as swimming or brisk walking. If women have not exercised routinely up to that point, they should begin with no more than three 15-minute sessions a week, increasing gradually to daily 30-minute sessions.

There are no formal evidence-based guidelines from the UK Government or professional bodies on what constitutes appropriate weight gain during pregnancy.
How do I safely lose weight after giving birth?

Women are encouraged to breastfeed, but are advised against dieting while breastfeeding. Women who feed their babies with breastmilk only for the first six months may require an additional 330 calories a day, but this may differ between individuals, and some of these additional calories will be derived from fat stores built up during pregnancy.

If the pregnancy and delivery are uncomplicated, mothers may start a mild exercise programme consisting of walking, pelvic floor exercises and stretching immediately after giving birth, but women should not resume high-impact activity too soon. Women who have had complicated deliveries or caesareans should not resume pre-pregnancy levels of physical activity before consulting their medical caregiver.

Health professionals should be able to provide details of appropriate community-based services for women who want support to lose weight.


Where can I get more information?

Women should consult their GP or midwife about maintaining a healthy lifestyle before, after and during their pregnancy.

Bad Ideas Can Be Contagious

Nearly four decades ago, psychologist Stanley Milgram had a volunteer stand stock still on a busy New York sidewalk and look up at the sky. About one in every 25 passersby stopped to look up, too. When five volunteers were recruited to sky-gaze, nearly one in five passersby stopped to look up.



When Milgram and his colleagues assembled a group of 18 volunteers to simultaneously look up at nothing in particular, nearly one in two passersby looked up to see what was going on, snarling traffic within moments.

In the intervening years a variety of experiments have unearthed similar findings in a number of domains. When people have limited information about something important -- a potential crisis in a building several stories high, a fire alarm that goes off in a crowded theater or a sudden drop in the stock market -- they use other people as guides to their own behavior.

This can be smart if the people on whom you are modeling your behavior know more than you do. But in many situations, no one knows very much. When you follow people who don't know what they are doing, and other people follow you, the resulting feedback allows small events to trigger huge and irrational changes in group behavior.

Such thinking was behind the "Washington's real estate market will never soften" belief between 2000 and 2005, and it's also behind the pervasive pessimism that plagues the same market today, said Robert Shiller, an economist at Yale University and the author of the book "Irrational Exuberance."

Shiller argues that patterns of market behavior have a lot in common with infectious diseases. His book explores the idea of "contagion" in financial markets -- except that instead of the flu, Shiller talks about the spread of dogmas from one place to another.

"I am talking of views that seem intuitively right," Shiller said. "One hears other people saying things and confirming ideas you have. When things are commonly accepted, you file it in your brain as something that is true."

One of those intuitively appealing ideas that was widely passed around during the Washington real estate boom was an example of what Shiller calls the uniqueness bias -- investors' belief that their particular investments are somehow immune to normal economic processes. In the D.C. area, that bias centered on the idea that, in the nation's capital, the real estate market is supposed to be largely immune to the kind of shocks that buffet other places.

But even if Washington real estate investments are marginally safer than those in other places, that has already been factored into the higher price of housing in the area and is therefore of little benefit to new investors, Shiller said.

Another problem Shiller has identified in the feedback loop is the role of hindsight and narratives in shaping market behavior -- a Monday-morning quarterback effect. Every rise and dip in the stock market, for example, is assigned a narrative on a daily basis. A particular set of factors is said to have caused the market to go up or down, and this judgment quickly becomes the general wisdom.

After a sudden stock market dip in 1989 was quickly ascribed to an airline merger, Shiller conducted a survey asking investment managers which they had heard about first, the market dip or the narrative explanation. Although nearly all the investment managers believed the airline merger story, no one had heard it before the market fell.
"Now we are all in agreement the housing market is going to fall," said Shiller, describing the latest version of market groupthink. "That is what happens when you have contagion of an idea. You are going around wearing a tie and you realize that no one else is wearing a tie, and suddenly it seems so wrong to be wearing a tie."

Jian Yang, who teaches finance at the University of Colorado Denver, and David Bessler, a professor of agricultural economics at Texas A&M University, recently showed that contagion played a central role in the 1987 stock market crash, in which several international markets with very different economic fundamentals moved together in lock step.

In a complex analysis that meticulously tracked data from several countries, and that is to be published next year in the European Journal of Operational Research, they showed how market weakness spread from one country to another, in a sort of international version of Milgram's passersby experiment in New York.

Yang said that although many investors recognize the problem of contagion and herding behavior, this does not keep them from following the herd, possibly because they feel less regretful about bad decisions if they know many other people made the same mistake.

As global communication has increased with the advent of the Internet, Shiller and others said, ever-greater feedback systems and contagion effects are likely in real estate and financial markets.

"A lot of Japanese investors admitted that they saw what happened with the U.S. market and had a gut panic" during the 1987 crash, Yang said. Rather than trust their own accurate assessments of Japanese economic fundamentals, they thought, "Maybe something is wrong with my assessment of the Japanese market."

Parents reject 'bossy' lunch box advice, says Ofsted

Many parents see schools as "bossy" or "interfering" when they tell them what they can and cannot put in their children's lunch box, Ofsted warns.
Instead parents in England wanted more advice on how to prepare healthier packed lunches, inspectors said.



They said heads often felt uneasy about issuing edicts on lunch boxes.
Inspectors also say some families who are on low incomes but are not eligible for free school meals are struggling to afford school dinners.
And they found some secondary schools in England still used systems which made pupils receiving free school meals readily identifiable.
Inspectors visited 39 primary, secondary and special schools in England between September 2009 and January 2010 to see how they were getting the healthy eating message across.
They found more primary than secondary schools complied with the standards set out for school lunches.


In primaries, the guideline most often not met was the requirement to provide a piece of fruit for every pupil eating a school lunch.
In secondaries, the standard most often not met were those restricting meat products, deep-fried foods and starchy foods cooked in oil.
Lunch boxes
Inspectors said schools' healthy eating policies could be undermined when pupils brought in unhealthy packed lunches.

While some schools brought in rules on lunch boxes, others were uncomfortable with this.
"Some of the head teachers spoken to were reluctant to do this because they did not think that they should tell parents what to do and did not wish to be patronising," the report said.

"Where consultation with families had been poor or where information had not been worded sensitively, parents saw the school as being 'interfering' and 'bossy' and reacted against the advice.
"Many of the parents with whom inspectors held discussions said that, rather than being told what not to give their children, they wanted more guidance on how to prepare a healthy and balanced packed lunch."
Free school meals
The report - Food in Schools - found most of the schools surveyed had come up with ways of increasing the uptake of school meals and free school meals.
But it found some of the secondaries were not doing enough to prevent children entitled to free school meals being singled out.
"Five of the 16 secondary schools still had systems where those entitled to free school meals could be readily identified by their peers," it said.

The report reveals concerns that parents who are on low incomes but are not eligible for free school meals (FSM) are struggling to find the money to pay for their children to be fed at school.
In one case, two children from one family had to take it in turns to have lunch, it says.


Children are eligible for FSM if their families receive benefits or have an annual income of less than £16,040.
The report says: "A more difficult area to tackle for the schools and authorities visited was the take-up of school meals by families whose income was low but who were above the threshold for being entitled to free school meals."
It adds: "Parents from these families told inspectors that they often could not afford to pay for a school lunch, especially if they had more than one child."
Inspectors found "the most significant and consistent weakness" was schools' monitoring of the food they provided and the impact it was having on pupils.

"A major weakness in the schools visited was the lack of monitoring of provision to ensure that the school food standards were fully met," inspectors said.
"Governors were often unaware of their responsibilities in this respect."
