Are the health supplements safe?

Health supplements are now a common addition to our diet and in many situations they are the only solution to our health problems. However the Internet is simply flooded by SPAM and pop-up advertisements promising a quick relief from various illnesses if only we take (put a name here) health diet supplement and they are treated more and more like some kind of wonder pills. On the other hand, the benefits and dangers of using them are more and more discussed among physicians. The use of various supplements in bodybuilding process and the dangers of abusing them do not help.

The point is that health supplement really do work, but not for everybody and certainly they're not for every occasion.

Nutritional deficiencies
Basically dietary health supplements were originally developed to help people overcome their nutritional deficiencies. If, for any reason, an individual is unable to follow a balanced diet, health supplements help them to keep your organism intact. However in most cases when an individual eats healthy food (a lot of fresh fruit and vegetables. For example), health supplements are no longer needed and taking them will have only little effect (and not always a positive one).

Bodybuilding/fitness
Another common reason of taking health supplements is bodybuilding. When we want more than to be fit, the normal diet is not enough and we need to take something more serious if we hope to keep up the unhealthily quick pace of the muscles grow. That's where the health supplements come. However as they are often taken without any medical knowledge (and they need to be taken in large quantities if they are to have a visible effect), their final effects may no longer be positive.

Conclusion
In short, health supplements are OK, but only as long as people use them for the reasons they were made for - to fight nutritional deficiencies. Bodybuilding or the general need of feeling healthy are not good reasons for taking those pills (even herbal ones). Our body is a delicate mechanism and we shouldn't tinker in it too much without a serious reason.

Are Prenatal Vitamins Really Necessary?

One of the first things that happens when a woman visits a doctor either in a visit to discuss becoming pregnant or the first visit after becoming pregnant is that she will receive a prescription for prenatal vitamins. It is such a common occurrence that most women don't give it a second thought. Vitamin supplementation is generally a debatable topic, but medical doctors agree that it is imperative for women who are pregnant. Consider the last time you had a nasty cold, for example. It is probably the case that your doctor did not prescribe that you take high doses of vitamin C as a treatment method.

Quite often, doctors are reluctant to prescribe vitamins for any health condition. So, why is it that they don't hesitate to prescribe prenatal vitamins? Quite simply, pregnancy means that a woman has to consume enough nutrients for two lives (more if multiple births are expected).

If people in general don't consume sufficient vitamins, it only makes sense that women would have a huge deficit of nutrients if they were to become pregnant. Not all prenatal vitamins are the same. While a woman will need sufficient amounts of all essential vitamins and minerals, the most important to a baby are folic acid and calcium. Folic acid is a B vitamin that is essential to prevent birth defects, especially those of the spinal cord and brain. A pregnant woman needs extra calcium so that the baby's teeth and bones can grow healthy and strong. The additional supply of calcium prevents the baby from the baby having to draw calcium from the mother's bone.

Of course, every woman has different needs. If you are a vegetarian, have a low tolerance for certain foods, or are on a restricted diet for health reasons, prenatal vitamins can provide you and your baby the nutrients you need that would otherwise not obtain. The exact vitamins you need is a determination that your doctor will make. Some women neglect to take prenatal vitamins and attempt to use a multivitamin instead. This is not a good idea since multivitamins rarely contain the additional nutrients that a woman needs when she is pregnant.

Are Mega-Doses Of Vitamins Safe?

In today's health-conscious society, much attention has been paid to vitamin supplementation and the role it plays in total body health. In addition to promoting optimum wellness, vitamin supplements are taken for reasons such as protecting the heart, reducing the risk of cancer, boosting the immune
system, relieving the symptoms of PMS, alleviating depression and anxiety, improving the memory, and even weight loss.

There have been some publicized theories that advocate the use of extremely high doses, or mega-doses, of certain vitamins. Care should be taken when considering this kind of supplementation. While some vitamins are safe in large doses, others can be harmful. Here are the most commonly used
vitamins and the safest maximum doses for each:

Vitamin A - Vitamin A is a fat-soluble compound that is crucial for healthy vision, cell growth, and immune system function. Vitamin A should not be taken in excess of 10,000 IU which is twice the daily recommended allowance for adults.

Vitamin B6 - Vitamin B6 is a water-soluble vitamin that is required for protein metabolism, the delivery of oxygen to cells, and the regulation of blood glucose. Excessive Vitamin B6 can cause debilitating and dangerous nerve damage. Do not exceed 100 mg of Vitamin B6 per day.

Vitamin B12 - Vitamin B12 is essential to healthy red blood cells and nerve cells in the body. Vitamin B12 also plays a vital role in the creation of human DNA. Although this compound is well-tolerated and has a low level of toxicity, it is recommended that you do not exceed 3,000 mcg per day.

Folic Acid - Folic acid contributes to the development of DNA, and is also needed for the metabolism of important amino acids. It is especially crucial for pregnant women. Folic acid has a low toxicity level, however the recommended maximum dose for adults is 1,000 mcg.

Vitamin C - Vitamin C is necessary for the production of collagen, growth and repair of the body's tissues, and a healthy immune system. However, too much Vitamin C can cause harmful oxidation in the body. No more than 2000 mg per day should be consumed.

Vitamin D - Vitamin D is essential for normal levels of phosphorus and calcium in the blood. Vitamin D is an important contributor to strong bones and teeth. Excessive Vitamin D intake (more than 10,000 IU) can lead to bone pain, nausea, vomiting, and even kidney stones.

Vitamin E - Vitamin E is an antioxidant that helps protect the body against free radicals. However taking more than 1,000 mg can cause heart problems and excessive bleeding.

Talk to your doctor to learn more about the safe dosage levels of vitamin compounds. It’s not always a good idea to buy into the latest health fads, or to believe the sales copy you read on the product bottle.

Are Liquid Supplements Right For Your Healthy Diet?

Liquid nutrition products like Ensure (tm) and Boost (tm) have been used almost exclusively in nursing homes and hoispitals, until recently. Lately we have seen nutritional companies marketing these drinks to people of all ages and all stages of health.

Liquid supplements are supposed to be the answer for busy moms running around with the kids, business people running out the door out without time for a sit-down breakfast, and older adults wanting to insure that they will be able to enjoy their grandchildren. But what do these liquid nutrion product really offer?

In general, these supplements are composed of water, sugar, milk and soy proteins, oils, vitamins, and minerals. An 8-ounce can generally has 250 calories, and the deluxe version may have as many as 355 calories. Most are lactose free, some have added fiber, and some are specifically designed for children or adults with certain health problems.

These companies are also selling supplements in the form of pudding cups and candy bar type products, with varous nutrientional content.

What nutritional need are companies trying to help consumers answer? Below are some of the reasons companies give for buying their products.

These companies ad campaigns are using fear tactics to make you worry that you are not getting proper nutrition from your ordinary meals. True, some people are consuming less than the Recommended Dietary Allowance (RDA) for some nutrients, this doesn't mean they will develop a deficiency disease. If you truly feel you are not getting enough nutrients from your food, you should contact a registered dietitian or a KSU Extension Specialist in nutrition. They can help you determine your needs for additional supplements.

These “Eat on The run” Liquid supplements may be a quick way to get vitamins, minerals and protein, but there is more needed for good health! Scientists continue to discover new ingredienets in foods that provide health benefits. Consider this; the canned supplements have a severe lack of fiber and other healthy components but are really high in sugars and calories. Although this was ideal for the original intent of the products, most healthy consumers don’t want or need all the extra calories that the supplement provides.

In summary, while there is a need for liquid nutritional supplements in some medical conditions, these products are unnecessary for the average, healthy person. In addition, one must consider the cost of an 8 once can of these liquid supplements to determine if they should be included in their dietary regimen.

Antioxidante, Free Radicals and Sports Nutrition

As you know, I am a physician. It's part of my profession to keep abreast of what's happening in medical /health research. Being retired helps, because doctors simply do not generally have the "extra time" to devote to the scientific literature.

But I do. And I love it. I am one of those individuals who really enjoys …brace yourself…chemistry. When I'm done here, you should be excited too, especially if you are interested in sports nutrition and antioxidants, though not necessarily in that order.

Sports nutrition is a vast industry with emphasis on optimizing PERFORMANCE. Off hand, I can think of quite a few categories involving sports nutrition:

" sports nutrition and supplements for athletes,
" sports nutrition and athletic performance,
" sports nutrition and body building,
" sports nutrition and endurance training,
" sports nutrition and special diets in a variety of sports,
" sports nutrition and strength training,
" sports nutrition for running, jogging, walking, skiing, swimming
" There's even Rocky Mountain sports nutrition
" …the list is endless.



So far, no surprises, huh? Well, here's one for you. Did you know that when you exercise intensively you INCREASE the free radical burden in your body? If you're a serious sports enthusiast, you should know that.

But…the real news is what science is now finding out about that free radical burden of yours. You should pay close attention here.

Suddenly, chemistry gets real personal.

Everyone of us has, what may be called, our antioxidant protective capacity. That means our bodies normally utilize antioxidants to protect us against the harmful impact of free radicals.

First of all, what are antioxidants? They are molecular substances which offset free radical damage to the body. Antioxidants, "quench" free radicals (for lack of a better metaphor) neutralizing their damaging effects on the cells of the body.

" Antioxidants are found in foods such as cranberries, green tea and even chocolate.

" Antioxidants are found in vitamins such vitamin C and E.

" Antioxidants are found in carotenoids such as beta-carotene.

" Antioxidants are found in many substances supplied by the body such as glutathione.

" Antioxidants are found in many herbs and enzymes.

The impact of antioxidants is boosted by glyconutrients to offset free radicals in your body…and, as a result of your athletic exertions.

Antioxidant capacity must be provided in your sports nutrition regimen or you could be "robbing Peter to pay Paul" with your workouts. As you will see, without a glyconutrional presence in your sports nutrition, the healthful gains made by your physical workouts will be offset by your own free radical burden.

Free radicals, sports and sports nutrition

Free radicals are those chemical species which contain one or more unpaired electrons, capable of independent existence. They form in the body due to a variety of reasons as offshoots of cellular activity or as products introduced to the body from the outside.

As an analogy, think of running a car engine as the cellular production
and the car emissions a the free radical production. The engine produces products which cannot stay inside the car without further damage. They simply must be neutralized and expelled.

Free radicals form and cause damage by reacting with many substances in your body. It is estimated that upwards of 200,000 free radical attacks occur in our bodies daily.

When free radical damage is done, the body can remove the compounds formed by its cellular repair system. However, if the body cannot handle the free radicals (with antioxidants for example), nor remove the compounds, then disease can be the result.

Contrary to popular opinion, free radicals do not circulate throughout the body. The half-life of most free radicals varies in a range of a few nanoseconds to about 7 seconds duration. That means they will react within the "neighborhood" (a few Angstroms or microns near where the increase in free radicals occurred) …organs, connective tissue, circulatory or nerve tissue, bone or lymphatic material are all candidates for free radical attack.

Wherever they form, they will damage the surrounding areas, unless prevented by the body…So the body does NOT have the luxury of just filtering away any circulatory fluids to find the free radicals. The body's defense systems must be…well…fairly omnipresent to neutralize the effects of free radicals. The antioxidant protective system must be healthy.

Since they are highly reactive substances, they react with all sorts of cell elements readily. But, when they do react with your body cells, they can damage the cells and even kill them. Often, the damage from free radicals can CHANGE the cellular structure enough to cause DISEASE such as cancer, diabetes, arthritis, heart disease and a host of others.

The type of disease that occurs is dependent upon which of the free radical defenses in the body weren't functioning properly and where the free radical attacks occur.

The body has pretty sophisticated antioxidant defense systems. But, the body CAN get overwhelmed in its antioxidant protections against such free radicals…

Indeed, unless antioxidant enhanced sports nutrition (with glyconutrients) are used to offset the increased free radical burden, the BODY will suffer as a result of intensive sports training, stress, and competition.

Glyconutrients VITAL to sports nutrition …

Studies comparing marathon runners who did and did not take glyconutritional sports nutrition supplements were undertaken. The results were reported by the Proceedings of the Fisher Institute For Medical Research ( August 2003, vol.3, no.1). The results "demonstrated strikingly different patterns." Antioxidant protection appeared to be powerfully enhanced against free radicals with glyconutritional supplementation. Thus, the body was protected for several days after the marathon run.

However, when glyconutritional sports nutrition was NOT used, the damaging effects of the free radical burden appeared to remain in the body for about five days. Thus, the subject "consistently excreted higher concentrations of free radical byproducts…" as compared to that of the glyconutritional subject. It should be emphasized that the subject studied WAS TAKING other antioxidants, though not glyconutrition. Despite that fact, the above cited results were obtained.

That's another way of saying that when glyconutritional supplements were not used, the free radical burden upon the body was not lifted. Antioxidant protection does appear to be (significantly) strengthened with glyconutritional sports nutrition. Such antioxidant protection appears to be of benefit for athletes overall, including training, stress, competition and dietary issues.

The glyconutrional revolution in sports nutrition and therapy is just beginning. More studies are being done. More results are coming in concerning free radicals and the capacity of the glyconutrients to boost antioxidant affect against free radicals.

Sports nutrition is about to see a new revolution…

Better still. I believe that it is quite probable that, with glyconutrition, sports PERFORMANCE is about to see a revolution in al fields.

Antioxidant Vitamins

The antioxidant vitamins found in fruits, vegetables, teas and supplements are proving to be powerful agents in the fight against disease causing free radicals.

The original concept was to take recommended daily allowance (RDA) of vitamins to a level that would prevent acute deficiency diseases like the Sailor’s disease scurvy. These are the standards by which RDA’s were created.

However, in recent years, research has shown that Vitamins taken in higher doses can prevent sever chronic diseases like cancer and heart disease. A debate still rages, but there is a plethora of research being done on Vitamin A, C, E, the antioxidant vitamins.

A National Institute of Health clinical trial involving people at high risk of developing advanced stages of Age-related Macular Degeneration (AMD), showed that patients’ risk decreased by 25 percent when treated with high doses of antioxidant vitamins and zinc.

Another study at the Center for Disease Control and Prevention (CDC) in Atlanta showed that taking Vitamin E along with multivitamins reduced risk from stroke and heart illness. Among patients who took the combination, mortality risk decreased by 15 percent for these two diseases.

This September, the National Institutes of Health (NIH) concluded a study investigating the relationship between Vitamin C and cancer, suggesting that Vitamin C may fight cancer. They found, in a laboratory setting, that high doses of Vitamin C injected directly into the bloodstream killed cancer cells.

Though the current RDA for Vitamin C is stuck at 60 mg, many researchers suggest that raising the RDA to between 100 and 200 mg would be a great way for people to get the antioxidants that they need to maintain overall well being.

Be careful when purchasing vitamins and supplements though. Research has shown that whole food vitamins, or vitamins with their co-factors, are much more effective than isolated nutrients. Nutrition is a complex process of thousands of chemical reactions within our bodies. Vitamins are always better in their natural state - in the foods we eat. Supplements should never be used in place of a poor diet.

The smart choice is to look for whole food vitamins to supplement an already good diet for the times you can't get everything you need at meal time.

3 Day Diet Menu

The author of the 3 day diet is not known, but this diet has been circulating on the internet for years now. This diet is a very strict plan, consisting of three days that have 3 specific meals consisting of about a thousand calories. These must be followed precisely and at the end of the 3 days you can resume normal eating for 4 to five days, and then restart the diet plan as you desire.

What a typical plan consists of is breakfast and lunch which both include black coffee or tea and you are only allowed one or two packets of sweetener. The breakfast meal always includes one fruit, one starch and a combination of protein and fat.

So for example the day one breakfast will include half of a grapefruit, a piece of toast and a tablespoon of peanut butter. Your lunch on that day will be a piece of toast, half a cup of tuna and one or two packets of sweet and low with the black coffee or tea.

As for your dinner meal on that day, you can have a protein, a starch, two vegetables and a fruit. You can have any source of lean protein and your vegetables can be any non starchy vegetable. Things like broccoli, carrots, cabbage and those type of vegetables. For your dinner fruit go with either half a banana, an apple or half of a grapefruit.

Although you may feel extremely hungry at some point during the day, the goal is to try stick to the diet and avoid cheating by either getting more food than you should or eating more times than the three allowed meals. Otherwise this is one of the easiest diets that are available for you to try.
