Appendix B to Dr. Herbertís Testimony, NY City Council, 2/10/00, re supplements: Appendix B to Dr. Herbertís Testimony, NY City
Council, 2/10/00, re supplements: Pages
488-89 of chapter 15 ìSupplements and ìHealth Foodsî from the book The
Vitamin Pushers by Stephen Barrett, MD, and Victor Herbert, MD, JD, MACP.
Hardcover, 536 pages, published 1994, Prometheus Books, Amherst, NY.
ISBN 0-87975-909-7. Glandular
extracts: These products, sold as ìfood
supplements.î are claimed to cure diseases by augmenting glandular function
in the body. Actually they contain no hormones and therefore can exert no
pharmacologic effect upon the body. If they did produce such an effect, they
would be dangerous for self-medication. Glutamic acid: Health-food
promoters claim that a variety of substances can increase memory power; one is
glutamic acid, the principal amino acid, metabolized by the brain. Although
scientists are studying the relationship between memory and the intake of
certain amino acids, using supplements with the hope of improving brain
function is at best premature and has been harmful. If oneís diet is
reasonably well balanced, there is no reason to add any amino acid supplement
with the hope of improving memory. Goat
milk: The milk of goats has been touted as a highly
nutritious substitute for cow milk; it actually is no more nutritious than cow
milk. The late Paavo Airola, naturopath and author of several books advocating
questionable nutrition practices, claimed that goat milk contains special
factors effective against arthritis and cancer. This is untrue. Like
nonpasteurized milk from any animal, goat milk can carry diseases. Granola:
Granola is the common term used to describe various cereals and
candy bars composed largely of oats plus other grains, fruits, seeds, and
nuts. Touted
as ìnaturalî and rich in nutrients, granola products tend to be high in
sugar (usually brown sugar and/or honey), fats (from vegetable oils, nuts,
seeds, and coconut), and calories. Green-lipped mussel: Green-lipped mussel, harvested in New Zealand and made into supplement capsules, has been marketed by several American companies. Claims that it is effective against arthritis are not supported by scientific studies. During the mid-1980ís, FDA action stopped a major manufacturer from marketing green-lipped mussel as an arthritis remedy. However, similar products are still marketed as ìmucopolysaccharides.î Guarana:
An herb that contains a significant amount of caffeine. Gymnerna
sylvestre: An herb claimed to decrease the craving
for sweets and to inhibit absorption of sugar by the digestive tract, thereby
causing weight loss. Although chewing the plantís leaves can prevent the
taste sensation of sweetness, there is no reliable evidence that the chemicals
they contain can block sugar absorption or produce weight loss. Honey:
Although honey is portrayed as more nutritious than table sugar, there is
little nutritional difference between the two. Honey is a crude form of mixed
sugars, mainly fructose arid glucose, with a small amount of sucrose and only
trace amounts of micronutrients. Table sugar is pure sucrose, whose molecules
consist of equal parts of fructose and glucose. Being sticky, however, honey
is more likely to contribute to tooth decay. It is also more expensive than
table sugar. Honeyís intense sweetness is due to the free fructose it
contains. Inositol: Contrary to
popular claims, supplements of inositol will not alleviate baldness, reduce
blood cholesterol levels, or aid weight loss. Inositol is not a B vitamin, and
the body can manufacture all the inositol it needs. Even if it were a vitamin,
supplements would be unnecessary because it is readily available in our food
supply. Lecithin: Lecithin is
manufactured by the liver and present in many foods, including soybeans, whole
grains, and egg yolks. Claims that lecithin supplements can dissolve blood
cholesterol, rid the blood stream of undesirable fats, cure arthritis, improve
brain power, and aid in weight reduction are unsupported by scientific
evidence. Ma huang: An herb that contains ephedrine, a
decongestant and nervous ‚system stimulant. Ephedrine can raise blood
pressure and therefore is hazardous to individuals with high blood pressure.
Products containing ma huang are marketed as weight-loss aids even
though they have not been proven safe and effective for this purpose. Some
entrepreneurs are selling ephedrine/caffeine combinations as
stimulants. Serious illnesses and deaths have been reported among users of
these products. Octacosanol: Raw wheat germ
is claimed to contain an active ingredient called ìoctacosanol.î This
substance, present in many plant oils, is not essential in the human diet.
Claims that it improves stamina and endurance, reduces blood cholesterol, and
helps reproduction are unsubstantiated. PABA (para-aminobenzoic acid):
A vitamin for bacteria, but not for humans. It is claimed that dosages
taken orally can prevent or reverse the graying of hair, but no
scientific evidence exists to support this claim. Papain: An enzyme, present
in papaya extract, that is promoted as a digestive aid, cure for
gum disease, and weight-reduction aid. When taken by mouth, |
