Can vitamin tablets lead to premature death?

Taking does not improve health and may increase the risk of , according to media reports.

A review of 67 found that taking the supplements vitamin A, and beta-carotene could lead to .

The evidence for and suggested that the pills did not increase the risk of death, but there was no benefit in taking the pills compared with a .

The researchers concluded that the current evidence does not support the use of in a healthy population.

There is no suggestion from the review, however, that a rich in of could be damaging to health, say the papers.

Around 12 million people in Britain are taking fuelling a £330 million industry.

What is the research?
The reports are based on the findings of a Danish study into the impact of on rates.

A search of published and other studies held by manufacturers identified 815 trials. But only 67 were considered to be adequately run randomised . These included 232,550 people aged an average of 62 years.

Twenty-one of the trials focused on the use of supplements in healthy individuals, while the rest tested patients with a range of . Trials including children, or patients with acute conditions, such as , were excluded.

What do the researchers say?
Lead author Dr Christian Gluud, from the centre for clinical intervention research at , called for better regulation of .

‘If a patient can eat a healthy, varied , then there is no need to take . According to our results this may even be harmful.

‘Based on our results, as well as the results from other studies, it seems that these supplements might increase the progression of cardiovascular and certain cancers.

‘It seems that the increased comes from an acceleration of disease progression rather than from the development of new .’

The team has not looked at whether a rich in natural could be harmful to health but it would be good to conduct some large scale trials into this, said Dr Gluud.

What do other experts say?
Anne Sidnell, nutrition scientist at the British Nutrition Foundation, said: ‘The findings of this study are in line with other studies that have shown that have no health benefits when consumed as supplements rather than through food.

‘Our bodies are designed to take in the correct amounts of from food, but there is a danger of overdosing when using supplements.’

There may be occasions when supplements are needed, such as supplements for the elderly or folic acid for , but overall a balanced is the best way to stay healthy, she added.

But Pamela Mason, nutritionist and spokeswomen for the Health Supplements Information Service, said: ‘Trials using have shown inconsistent findings and yet another review or meta-analysis is not going to tell us anything at this stage.

Truth about vitamin pills is hard to swallow

WOULDN’T it be wonderful if there were a range of magic pills we could take once a day to protect us from all manner of ?

One to ward off , another to keep our in check, and yet more to keep us mentally astute, with slim, well-toned bodies and glowing complexions.

We could drink beer, smoke tabs and eat burger and chips to our heart’s content and never have to worry because all the nasty side-effects would be cancelled out by a cocktail of .

You’d be forgiven for thinking many people already believe this to be possible, though admittedly to a lesser extent. But there’s surely no denying that millions of us are under the illusion that popping a few pills can cure a variety of ills.

I’m not talking about genuine, tried-and-tested medicines here . . . I’m referring to .

An estimated 10m people in the UK regularly take , shoring up a whopping £350m-a- year industry. Goodness knows what the industry is worth worldwide. But if a new report is to be believed, they’re wasting their money.

In what is claimed to be the most in-depth study ever undertaken into the effects of supplements, a team of Danish scientists concluded that there’s no evidence that they are of any benefit to health.

Worse still, they say some — including Beta- carotene, vitamin A and — actually endanger life and could “significantly increase ”.

Whenever I read stories like this I feel like I’ve wandered onto the set of the old Woody Allen movie Sleeper.

Allen’s character, having been cryogenically frozen for hundreds of years, is brought back to life in the future where everyone smokes because scientists have discovered tobacco is the healthiest substance known to man.

Now we’re faced with a version of Allen’s movie in reverse . . . it seems everything we thought was good for us is bad for us. Either that or it makes no difference, in which case, it’s still bad for us financially. So how come so many of us have fallen for the ? I suspect the answer is that people believe work because that’s what they want to believe . . .

And because the truth is as unpalatable to them as the fresh they have shunned in favour of supplements.

Unfortunately, however, there are no magic pills. And it’s high time we accepted that fact and stopped throwing money at an industry that has become adept at selling us an impossible dream.

A healthy and plenty of exercise is the only answer . . . that’s the hard-to-swallow truth scientists have been telling us for years.

Popping vitamins could seriously damage health

Popping vitamin pills ‘like sweets’ could seriously damage your health, warn experts

HEALTHY people who take were last night urged to be careful after research suggested they may do more harm than good.

Welsh advised people to meet their nutritional needs by eating five portions of a day.

There were also calls for tighter regulation of the sale of , which the public can buy “like sweets”, according to dietary .

The warning comes after researchers found that people who take , including A and E, to try to keep such as at bay, could in fact be interfering with their natural body and may be increasing their risk of an early death by up to 16%.

About 12 million supplement their diets with and the industry is worth about £330m a year.

, chairman of the National , said: “We all need up to a certain level, but there is a misconception that taking more must be good for you.

“The evidence shows that this isn’t true. Having too much does no good and, in fact, could do people harm.

“The key is to have a very varied with at least five portions of per day.

“More regulation of this industry is probably required.”

, including A, E, C and beta-carotene and , are said to mop up disease-causing compounds called . It is this action that researchers say may cause problems with the .

The research by , released by the influential , applied only to synthetic supplements and not to that occur naturally in vegetables and fruit.

Researchers carried out a review of 67 studies on 230,000 healthy people and found “no ” that any of the helped to prolong but some “increased ”.

They found that vitamin A supplements increased the risk of death in healthy people by 16%. Taking beta-carotene was linked to a 7% increased risk, while regular users of supplements increased the risk of an early death by 4%.

Although the review found no significant detrimental effect caused by , it found no evidence that it helped ward off disease. Millions take it in the hope of avoiding a common cold.

Goran Bjelakovic, who led the review, said: “We could find no evidence to support taking to reduce the risk of dying earlier in healthy people or patients with various .

“If anything, people in trial groups given the beta-carotene, vitamin A and showed increased rates of .”

“The public can buy as easily as sweets. They should be treated in the same way as paracetamol with maximum limits on the dosage.”

Camille Clarke, a naturopathic nutritionist, based at the Natural Health Clinic in Cathedral Road, Cardiff, backed calls for tighter controls.

“It [the industry] needs to be regulated, are too freely available,” said Camille, who urged people to opt for naturally- occurring .

“People read things in magazines and they are taking huge amounts of but have a terrible .

“There’s no point in taking if you don’t have a healthy . You should only take them if you have a health problem and only for a little while.”

Denise Parish, a lecturer in dietetics at the University of Wales Institute, Cardiff, and a state registered of 14 years, said: “As a general rule there is no evidence to say taking is of any benefit. Actually eating the foods that contain them is the best way of getting .”

She said the only people who should take are those who have particular health problems or who are advised to take folate.

The chief medical officer for Wales, Dr Tony Jewell, said: “A good balanced which includes fresh will always provide individuals with the that they need.

“We would always advise people not to rely on such supplements as their primary source of vitamin intake.”

Growing your own groceries is healthy and can save money

A garden may mean to different people. To some, it’s a way to trim back the grocery budget. If laid out properly and maintained, a 50-by-50-foot garden could produce all the vegetables a family of five would need for a year. Even a 20-by-20-foot plot could produce enough food to greatly impact that weekly trudge to the grocery store.Some find it relaxing, some, a source of exercise. Light gardening will burn 170 to 240 calories an hour, while vigorous work such as spading and hoeing will burn 250 to 350.
Most have found how much better homegrown harvest tastes than the store bought stuff and how much better it is for you. Tomatoes that are picked green will ripen with 1/3 less than vine ripened ones, and will lose 2/3 of its six days after harvest. But even when stored for a period of time, good amounts of disease fighting beta-carotene are found in winter squash, and .

Why should it surprise us that fresh, just-picked veggies are the best for us? You wouldn’t need to take another store bought vitamin if all your vegetables came from your garden.

Going down the list we find that is high in A, C, B1, and Calcium. Because they root deep they become a good source of minerals too. are high in A and C, while turnips are packed with B2 and E.

Besides the found in , significant amounts of B1, calcium, and make the carrot one of the best snacks you could give your little munchkin. They would consider it a tasty treat if it came from your garden; the store stuff can taste pretty bad sometimes, thus leaving a bad taste in their mouth for veggies.

Parsnips, when harvested in the winter under 12 inches of leaves, will give you a whole new appreciation for this B6, C and potassium packed, cream-colored, carrot-looking thing. Other vegetables whose flavor sweetens with each passing frost include , which has more body-ready calcium than a could ever hope for. Brussels sprouts are just plain stuffed with everything. And just one serving of Cauliflower will give you all the your body will need for that day. Cabbage goes beyond that, adding good amounts of B1, B2, A and calcium as well.

Onion and leeks rate high in A, C and E, with corn adding A, B and some minerals, though not in very big amounts. My wife says there is not much nutrition in sweet corn; and I guess after it’s been smothered in butter and sprinkled with salt, any good has probably been canceled out. But I tell her, “It’s got to be better than a Twinkie.”

There are many more, including spinach. We around 50 years old know what gigantic muscles can be had by downing a can of this stuff, and these are necessary when protecting our Olive Oyls from the Blutos in our lives (I still don’t know what he saw in her, what a bean pole).

If gardening is your thing, whatever your reason, be it saving money or good health, your tastes buds and, more importantly, your children’s buds will say, “I didn’t know veggies could taste this good.”

Organic milk: Dietary source of vitamins and antioxidants

ORGANIC MILK has been found to be a valuable dietary source of and , almost next in effectiveness to .

Higher and in organic milk

A recent research conducted by the Danish Institute of Agricultural Sciences and the University of Newcastle has revealed that organic milk is 50 per cent higher in the alpha tocopherol compound of , 75 percent higher in , which is used by our bodies to convert to vitamin A, and has almost three times higher (lutein and zeaxanthine) than non organic cow milk.

The report also stated that organic milk contains higher levels of omega three . This is mainly because organic cows are not only pastured grazed, but are also fed with more quantity of red clover than conventional cows. Red clover contains large amount of omega three which ultimately reaches us through the organic milk.

Another research from the University of Liverpool showed that organic milk contains 68 per cent more omega three . Omega three deficiencies has been the major cause of various health problems such as heart disease, inflammations (in skin such as eczema), , arthritis, etc.

Powerful in organic milk

Both beta-carotene and Alpha tocopherol, the most active of compounds, function as powerful . While the former helps reduce the risk of developing , the other counters the harm caused by , which cause ageing. Beta-carotene is useful for strong eyesight, greater resistance to infections, good skin, , , reproduction and . Major studies have found that these don’t have much value, if taken as supplements, instead of directly from food items.

Lutein and zeaxanthine , which are in the vitamin A category, help prevent cataracts, macular degeneration (deteriorating eye sight as we age) and atherosclerosis (when the blood vessels block up). Women get 17.5 per cent of the required intake of and men 14 percent by drinking a pint of organic milk a day. A pint of milk also provides the same quantity of beta-carotene as a portion of some vegetables such as Brussels sprouts.

Benefits from meeting organic requirements

Grass or grain, feed for organic farm cows has to be grown without pesticides. Cows reared in organic farms and fed on a rich of forage, fresh grass and clover, develop to become healthier. It is mandatory for United State Development Agriculture (USDA) organic labeled milk to come from cows that has not been treated with bovine growth hormone (BGH) to increase milk production.

Another vital requirement for organic cows is that they must have access to pastures. Studies have found that organic milk has more Conjugated Linoleic Acid (CLA). CLA promotes metabolic rate, immunity to and muscle growth, and at the same time, brings down abdominal fat, , and allergic reactions. Cows that are grazed on pastures have been found to produce 500 per cent more CLA in its milk than cows that are fed fodder. There has been increased in the interest of organic milk after recent research on animals showed that CLA is beneficial in treatment.

Non-organic cows

The research found no additional nutritional benefits in non-organic cows. Such cows are fed on a cheaper , high in energy rich concentrates to increase milk yields. Non-organic farmers also freely use GM cattle feed, urea and solvent extracted feeds and waste from food factories.

Folate Intake May Help Father Conceive Healthy Children

Folate Intake May Help Father Conceive Healthy Children

Men who have their based on , fruits and lentils have a higher chance of fathering a healthy child, a new research shows.

Scientists at the University of California, Berkeley and the Lawrence Berkeley National Laboratory found that men with relatively low levels of folate (a ) had increased risks for sperm containing either too few or too many chromosome, a condition known as aneuploidy. This condition is connected to failure to conceive, miscarriages, and children born with conditions such as Down’s syndrome, Turner’s syndrome and Klinefelter’s syndrome.

“We looked at sperm to find different kinds of genetic abnormalities. The abnormalities we looked at here were having too few or too many chromosomes,” lead researcher Brenda Eskenazi, a professor of maternal and child health and epidemiology and director of the Center for Children’s Environmental Health at Berkeley’s School of Public Health said, according to the Washington Post.

The researchers analyzed sperm samples from 89 healthy, non-smoking men and questioned them about their daily intake of zinc, folate, , and beta-carotene. They found men with the highest intake of folate or folic acid (between 722 and 1150 a day) had 20 percent to 30 percent lower frequencies of aneuploidy compared to men with a lower intake. No correlation was made between the other and sperm aneuploidy.

The current recommended daily intake of folate for men over the age of 19 is 400 . recommend women of childbearing age maintain a healthy intake of folate because it is essential for healthy fetal developmental and to prevent birth defects such as spina bifida or anencephaly (severe type of brain damage). That’s the reason why folic acid is now added to bread, cereal, flour and other in the U.S.

This study is the first to “say that male may be important for healthy offspring as well.”

“The emphasis related to the birth of a healthy baby has been weighted towards the health and of women, not just during pregnancy, but before. What we’re finding now is that a nutritious , specifically folate intake, may be beneficial for men as well when it comes to producing healthy offspring,” Dr. Eskenazi said.

She also adds that if other studies confirm her team’s findings of the link between folate intake and aneuploidy, scientists may recommend men tale folic acid for at least three months before trying to conceive.

The idea that can improve sperm quality is less well established. “There is increasing evidence from a number of studies to suggest that dietary factors can correlate with sperm health. The story so far suggests that dietary factors won’t help you make more sperm, but good might just improve that quality of the ones that are made,” said Dr. Allan Pacey, senior lecturer in andrology at the University of Sheffield and honorary secretary of the British Fertility Society, BBC News reported.

The study findings are published in the March 20 issue of the journal Human Reproduction.

Levels of folate in men’s diets linked to chromosomal abnormalities in their sperm

Researchers have found an association between a vitamin found in leafy , fruit and pulses and levels of chromosomal abnormalities in men’s sperm. Men who consumed high levels of folate (a water-soluble that occurs naturally in food) and folic acid (the synthetic form of the vitamin) tended to have lower levels of abnormal sperm where a chromosome had been lost or gained (known as aneuploidy).

Writing in Europe’s leading reproductive journal, Human Reproduction, today (Thursday 20 March), the authors say estimates suggest that between 1-4% of sperm in a healthy man have some type of aneuploidy, but there are large variations among individuals, the mechanisms are poorly understood and little is known about the effects of men’s on their sperm.

In the first study of its kind to investigate the relationship between sperm aneuploidy and paternal , they analysed sperm samples from 89 healthy, non-smoking men and questioned them about their daily total intake (from and from ) of zinc, folate, , and beta-carotene.

One of the principal investigators of the study, Brenda Eskenazi, Professor of Maternal and Child Health and Epidemiology and Director of the Centre for Children’s Environmental Health at the School of Public Health, University of California, Berkeley, USA, said: ‘We found a statistically significant association between high folate intake and lower sperm aneuploidy: there was increasing benefit with increasing intake, and men in the upper 25th percentile who had the highest intake of folate between 722-1150 , had 20-30% lower frequencies of several types of aneuploidy compared with men with a lower intake.

‘However, this study cannot prove that high folate intake caused the lower sperm aneuploidy levels, only that there is an association. This is the first study of its kind and the results indicate the need for further research, especially a randomised controlled trial, on this topic.’

The researchers found no consistent associations between intakes of zinc and the other and sperm aneuploidy.

Prof. Eskenazi said: ‘While the importance of maternal on reproduction, especially folate intake, is well known, the results of our study suggest the importance of studying paternal nutrition when considering male-mediated developmental consequences. In previous studies, we and others have shown that paternal micronutrient intake may contribute to successful conceptions by improving the quality of the sperm. This study is the first to suggest that paternal may play a role after conception in the development of healthy offspring.’

The current recommended daily intake (RDA) for men aged over 19 is 400 , and the authors say that if other studies confirm their findings of the link between folate intake and aneuploidy, then a possible intervention would be to increase the RDA for men considering becoming fathers for at least three months before trying to conceive in order to reduce the risk of chromosomal abnormalities in their children.

Ms Suzanne Young, a researcher in Prof Eskenazi’s group and the study co-ordinator, said: ‘Increasing folate intake can be as simple as taking a vitamin supplement with at least 400 of folate or eating breakfast cereal fortified with 100% of the RDA for folic acid. In addition, green leafy vegetables, such as spinach, can have up to 100 of folate per serving.’

Disentangling the effects of folate from other micronutrients (e.g. the other ) can be difficult, but the authors think they have succeeded in doing this by looking at several different in statistical analyses. Ms Young said: ‘The results of the different analyses were different, which gave us some confidence that we could look at the effect of these micronutrients separately. The definitive way to answer this question would be with a randomised control trial with folate supplementation.’

Vitamins Can Rescue Skin, Hair and Nails

The old saying still holds true: You are what you eat. Some of us believe we can afford to disregard this dictum, as long as we have a plastic surgeon, a salon and a day spa on speed dial.

We want to be thinner - we get liposuction. Our hair is thinning - off to the salon for extensions. Our nails become brittle - acrylic nails are a phone call away.

What most of us fail to recognize is that these changes (skin, hair and nails) are our body’s way of screaming for help. What keeps you clean and healthy on the inside will keep you looking good on the outside.

If you want clean and , drink more water. Your kidneys remove waste products that must be dissolved by water. By drinking around eight glasses of water a day (this is an average; everybody has different requirements), you are flushing out the toxins that would normally escape through the pores of your skin. This prevents and blemishes, and helps keep the skin moisture level even.
