TAKE SUPPLEMENTS DAILY By Dr. Tony Vendrye

Of several remedies, the physician
should choose the least sensational.’
– Hippocrates

Up to as little as a decade ago, mainstream medicine has been openly hostile to the idea of healthy people taking vitamin supplements. Only recently has this anti-vitamin position begun to change, as irrefutable evidence emerged showing that vitamin supplements could reduce the risk of many common diseases. Sadly, it is still common practice for doctors to tell their patients that they do not need vitamin supplements if they are eating a ‘balanced’ diet.

In April 1998, the editorial in the New England Journal of Medicine was entitled ‘Eat Right and Take a Multi Vitamin’. This article indicated that certain vitamin supplements could reduce the risk of heart attacks and strokes. This was the first time that a prestigious medical journal was recommending vitamin supplements. An even stronger endorsement for the use of vitamin supplements came in the June 19, 2002 issue of the Journal of the American Medical Association. Harvard University doctors reported that people who got enough vitamins might be able to prevent such common illnesses as cancer, heart disease and osteoporosis.

Today one in every three North Americans takes multivitamins but many are reluctant to tell their doctors for fear that they may disapprove. The same situation exists right here in Jamaica, although a number of my Jamaican medical colleagues are now regularly recommending vitamin and herbal supplements to their patients. I applaud them for this refreshing change.

TAKE NUTRITIONAL SUPPLEMENTS
However, to complicate the issue, research suggests that as much as one third of dietary supplements (vitamins, minerals and herbals), have one or all of the following problems:
• The products do not contain what the label says it should.
• The products contain other undisclosed substances in addition to what is on the label, which may create a health hazard.
• The active ingredients in a supplement may not be readily absorbed by the system, and may thus be ineffective.

Fortunately, the Jamaican Ministry of Health has been active in seeking to protect the interests of the public in this matter. I hope, however, that in doing so the right of the individual to choose supplements for himself or herself will not be infringed upon. After all, the possible problems that may arise from taking supplements are minute when compared with the side effects of prescription medication. Just imagine, over 150,000 Americans die each year from the side effects of drugs prescribed by their doctors! By contrast, last year the Center for Disease Control reported no deaths at all from the use of vitamin and herbal supplements.

The following guidelines will help you in your choice of nutritional supplements.

Choose a reputable brand
The cheapest brand is not necessarily the best. Choose products from a company that has a well established reputation for high quality and effective products.
Speak with individuals who have used that brand and have them share their experience with you. Well-trained network marketers of nutritional supplements are particularly helpful in this regard, as they are usually heavy consumers of the products they sell. Some, but not all, health food store personnel may also be helpful. I myself very carefully select the brand of supplements I recommend to my clients.

Read the labels
The US Food and Drug Administration does not approve dietary supplements but monitors and regulates their use by certain laws such as:
* The Mega dosage Law, which says that no food supplement should have an amount of any one ingredient that could create harm when taken at the recommended dosage.
* The Labeling Law, which says that any potential side effect that a dietary supplement may have and any necessary warnings about the use of such a product should appear on the product’s label. They also strictly restrict manufacturers from making medical claims that have not been scientifically validated. Unfortunately, unscrupulous manufacturers sometimes get away with outright fraud and that is why I so strongly recommend that you do your own due diligence and only use products from highly reputable companies.

Pay little attention to RDA (Recommended Daily Allowance) values on the labels. The RDA is the minimum amount of a vitamin necessary to prevent you from being seriously deficient. I and many experts believe that those levels are far too low for optimal health benefits and that the RDA is obsolete and irrelevant to modern nutritional practice.

Educate yourself
The more informed you become about nutrition, the more responsibility you can take for maintaining excellent health. There are many books, tapes, seminars and Internet sites that provide good information. I recommend my own Book and Radio Show An Ounce of Prevention, as a good information sources. Remember, ‘Your Health is in your Hands’.

Talk with your doctor
It is important that your physician knows that you are taking supplements. If your doctor is unwilling to discuss the matter with you, then I would suggest that you seek a second opinion or even change your health care provider. Remember, doctors are often not well educated about nutrition and nutritional supplementation.

Balance your nutrition
Despite their importance, supplements alone are not a replacement for a balanced, healthy diet. They should complement your diet. Particularly try to have at least seven servings of fresh fruits and vegetables daily, as they contain a variety of beneficial substances, known and unknown. As we often lack protein, I also recommend that you include a high quality nutritional protein shake drink in your daily diet. It facilitates good Cellular Nutrition, an essential for good health for everyone.

Many ignorant on 'waist fat' risk


Almost nine in 10 people are not aware of the risks of carrying extra fat around their waistline.

A survey of 12,000 Europeans found most had no idea that a thick waist was a sign of a build-up of a dangerous type of fat around the internal organs.

The report from GlaxoSmithKline, who make weight loss drug Alli, said this "visceral fat" is strongly linked with type 2 diabetes and heart disease.

Most people would lose weight once they found out the risk, the survey found.

Report author Dr Terry Maguire, honorary senior lecturer at Queen's University in Belfast, said people did not know that visceral fat, which you cannot see or feel and which sits around the organs in the abdomen, is there or that it poses a problem.

It is thought that the danger of visceral fat is related to the release of proteins and hormones that can cause inflammation, which in turn can damage arteries and enter the liver, and affect how the body breaks down sugars and fats.

It is the weight around your belly which really does the harm Professor Steve Field, Royal College of GPs

Only a quarter of those questioned in the Europe-wide study thought being overweight was a risk to long-term health at all.

"Most overweight people still see themselves as having a body image issue not a health problem and they need to understand the health benefits of weight loss as well as the cosmetic results," he said.

Waist Measurement

Research has shown that waist circumference is a good indicator of visceral fat and therefore of a person's risk of diseases associated with being overweight, such as type 2 diabetes.

The report pointed out that when weight is lost visceral fat is more easily broken down for energy than the fat immediately under the skin and even a small amount of weight loss can cause a difference.

When asked about losing weight, two-thirds of respondents said they would go on a diet in the New Year.


WAIST SIZE
Diabetes UK advises that the following waist measurements put people at risk:
Women: 31.5 inches (80 cm)
White men and black men: 37 inches (94cm)
South Asian men: 35 inches (90cm)

But the report's co-author Professor David Haslam, chair of the UK National Obesity Forum, cautioned that steady sustainable weight loss is important and that crash diets were likely to be unsuccessful.

"They can actually do more harm than good," he said.

"Invariably weight is put back on, with some of the weight regained accumulating as visceral fat."

It comes as the Department of Health announced that more than 300 of the 1,500 babies who were likely to have been born this New Year's Day could be overweight or obese by the time they start school unless action is taken.

Professor Steve Field, chair of the Royal College of GPs, said most of the focus in recent years had been on weight.

"It is the weight around your belly which really does the harm.

"A lot of these things take a while to get into people's heads especially as there has been so much focus on weight and body mass index.

"I'm not surprised at the findings because it will take more than a few academic papers to really change people's minds."

Healthy Breakfast


DID YOU KNOW that it is 4.5 times more likely that those who skip breakfast are obese compared with those who eat a morning meal?

The American Dietetic Association says breakfast is the most important meal of the day. And despite the healthful benefits, breakfast may be the meal that is most often neglected or skipped. Eating breakfast not only aids in weight management, it fuels the body to help provide energy, better concentration and problem-solving ability throughout the day, according to the food and nutrition experts at the American Dietetic Association.

Eating a Balanced Breakfast (or Alternative Meal) results in far fewer cravings, far less hunger, and up to five times more weight loss than a low-carbohydrate diet

THEREFORE, whatever your reasons, make sure you have a healthy breakfast to keep you going everyday. Why don't you share this with your friends to remind them?

THE DAILY HEALTHY BREAKFAST

Cola and unhealthy lifestyle lower sperm count - http://bit.ly/bwMzng


March 31, 2010 by Lin Edwards

(PhysOrg.com) -- A Danish study suggests drinking a lot of cola regularly could men’s lower sperm count by almost 30 percent. The culprit does not appear to be caffeine, since coffee did not have the same effect, even though it contains even more caffeine than cola.

Leader of the research team, Professor Tina Kold Jensen of the University Department of Growth and Reproduction at the Rigshospitalet in Copenhagen, said the results of previous studies on the effect of caffeine on male fertility had been unclear, and the study participants had usually been carefully selected, often because they were infertile or about to undergo vasectomy. The current study included 2,554 young men and aimed to find out how the increasing consumption of soft drinks containing caffeine by young people in Denmark might affect male reproductive health.

The participants were recruited in the period 2001 to 2005 when they were having their compulsory physical examination to determine if they were fit for military service. They were asked to complete a questionnaire about lifestyle and diet, including information on their intake of caffeine from various sources including cola, and they also delivered a semen sample.

The results were that those with low to moderate total caffeine intake and cola consumption (up to 800 mg/day caffeine and up to 14 x 0.5 liter bottles of cola per week) showed no link with semen quality in terms of sperm concentration and sperm count, while those with high intake of total caffeine and/or cola (over 800 mg/day and more than 14 x 0.5 liter bottles/week) had reduced sperm count and concentration, but this was only significant for the cola intake. Those with low to moderate consumption (the vast majority) had higher sperm counts (average 56 million/ml) than those who drank cola. In the 93 men who drank a liter (a quart) or more a day the sperm counts were much lower (35 million/ml). Even the lower count is within the World Health Organisation’s reported normal limits, but a reduced sperm count increases the risk of eventually becoming infertile.

The study found no link between caffeine in tea or coffee and the lowered sperm count, which meant the effect may be produced by other ingredients in the soft drinks, or other factors related to lifestyle, but the authors said they could not “exclude the possibility of a threshold above which cola, and possibly caffeine, negatively affects semen quality”. The researchers also found that those who drank cola had unhealthier lifestyles, ate less fruit and vegetables, and more fast foods than those who did not. It is therefore unclear if one or more of the cola’s ingredients, the unhealthy lifestyle, poor diet or a combination of these factors is responsible for the reduced sperm quality.

The study findings are published in the American Journal of Epidemiology.
