Numerous studies and surveys have consistently shown that a
majority of adults frequently eat foods that contain too little vitamin
B-6 and vitamin E. We consume far too many calories, and too much total
fat, saturated fat, cholesterol, and sodium. Women frequently eat too
little folic acid, iron, calcium, and zinc. This is why it is so
important to take a multi-vitamin daily.
The basic nutritional
needs of men and women who smoke are similar to those who don't use
tobacco. However, conclusive evidence exists that smokers need much
more antioxidant nutrients than non-smokers.
Essentially, smokers
need antioxidant nutrients such as vitamin C (also known as ascorbic
acid), and vitamin E. It was once believed that beta-carotene was an
attribute for non-smokers, but recent clinical studies have found that
beta-carotene can actually be harmful to smokers' health. Beta-carotene
can be found in most multi-vitamins and an excess of beta-carotene is
risky for good nutritional health. If you are a smoker and going to
take a multi-vitamin, be sure it doesn't list beta-carotene as one of
the ingredients.
Too many smokers have inadequate intakes of
antioxidants. Smokers are reported to consume lower quantities of
antioxidant nutrients than nonsmokers. Antioxidant nutrients have
protective roles with regard to cancer, heart disease, cataract
formation, cognitive (mind) dysfunction, and other diseases. Researches
believe there is a balance between antioxidant protectors and
components that promote oxidation in the body. This balance seems to be
related to health or disease. Some components of cigarette smoke
promote oxidation that provides high levels of oxidant stress. Free
radicals, which also promote oxidation, are derived from tobacco.
Cigarette smoke has been estimated to contain 1,000,000,000,000,000 free
radicals per inhalation. These free radicals can oxidize the fat
components of the body and this is quite harmful.
For instance,
cigarette smokers have lower vitamin C (natural antioxidant) intakes and
plasma vitamin C levels than nonsmokers. The incidence of cancer,
heart disease, and cataracts is lower in populations that have high
intakes of fruits or leafy green vegetables, all replete with vitamin C.
Smokers who ate foods containing more than 200 mg vitamin C daily had
serum vitamin C levels equivalent to those of nonsmokers who consumed 60
mg or more of the vitamin, according to a recent national survey. The
most recent edition of the Recommended Dietary Allowances recommends
that regular cigarette smokers take in at least 100 mg of vitamin C
daily. Smokers have been found to have higher levels of vitamin C in
the lung tissues than nonsmokers. This clearly reflects a positive
defense mechanism against the free radical species from cigarette smoke.
Studies
have found that smokers have a 30 percent lower vitamin C level than
nonsmokers. Researchers believe that nicotine may interfere with
vitamin C absorption. Nicotine boosts metabolic rate, therefore
increasing the rate that vitamin C is metabolized. Individuals who
smoke need 100 milligrams of vitamin C (versus 60 milligrams for
nonsmokers) every day.
The body's most effective antioxidant is
vitamin E. Smokers have been found to have lower levels of plasma
vitamin E than nonsmokers.
Smokers seeking nutritional
supplementation should look for a multi-vitamin that contains at least
all of the following: Vitamin C (Ascorbic Acid), Vitamin E, Vitamin B1
(Thiamine), Vitamin B2 (Riboflavin), Niacin, Vitamin B5 (Pantothenic
Acid), Zinc Picolinate, Vitamin B6 (Pyridoxine), and the antioxidant
Co-Q10. Some supplements add Ginkgo Biloba Leaf Powder, Inositol,
Rutin, Citrus Bioflavonoid Complex, Choline Bitartrate and PABA.
If
you smoke, or live with someone who smokes, it is important that you
make the right choices to safeguard you health against the risks
associated with smoking. One of the most important decisions you can
make is choosing the right multi-vitamin. It's a fact that smoking
depletes the body of important nutrients. It's also a fact that one
nutrient, beta-carotene, has been found in clinical studies to adversely
effect smokers' health. Beta-carotene, a form of Vitamin A, can be
found in most multi-vitamins.
