CAN SUPPLEMENTS TAKE THE PLACE OF A BAD DIET?

Can supplements take the place of a bad diet?

 

They'd better.

 

In spite of decades of intense and well-funded mass education, " 70 percent of

all adults and children in the U.S. do not eat the recommended five to nine

servings of fruits and vegetables a day for good health, " according to an April

25, 2002 press release by the National Cancer Institute. (1) And when a

" serving " of fruit may be a 6-ounce glass of juice and a " serving " of a

vegetable is a mere half-cup of beans, it really makes you think.

 

Since at least half of all Americans take vitamin supplements every day, one

might be tempted to say that, to a considerable degree, the people have already

answered this article's title's question. The public now, finally, has the

support of orthodox medicine. After years of disparaging supplements, the

Journal of the American Medical Association has recently published the

recommendation that every person take a multivitamin daily (2,3), saying that

" (S)uboptimal intake of some vitamins, above levels causing classic vitamin

deficiency, is a risk factor for chronic diseases and common in the general

population, especially the elderly. " Therefore, JAMA's intent goes beyond

routine nutritional insurance for widespread bad-to-borderline diets. The goal

is stated in the article's title: Vitamins for chronic disease prevention in

adults. It is a sensible idea whose time should have come generations ago.

 

Supplementation's harshest critics have traditionally railed against vitamins

(especially in large doses) as being outright " dangerous " and at the very least

" a waste of money. " Even as late as this year, the New York Times (4) expanded

the attack to question folic acid supplementation and even the practice of

taking a daily multivitamin, saying, " vitamin supplements cannot correct for a

poor diet (and that) multivitamins have not been shown to prevent any disease. "

 

The NY Times may have neglected to emphasize the real story: people eat

terribly.

 

Though eating less fat, more Westerners are more obese than ever before, and in

the United States, an astounding 80% of persons over the age of 25 are

overweight. Nearly two-thirds of all Americans (more than 120 million people)

are overweight or obese, according to the 1999-2000 National Health and

Nutrition Examination. (5) Protein and sugar intake is still astronomically high

and fruit and vegetable consumption is still ridiculously low.

 

While vitamin supplements do not produce weight loss, persons trying to lose

weight face a nutritional adequacy problem of their own. Approximately 50

million Americans admit to being " on a diet " at any given time. Virtually all

popular unsupplemented weight loss plans are nutrient deficient. For many,

eating less food means eating fewer food-source vitamins. Taking supplements can

be seen as especially important for all people that are dieting.

 

Dieticians have set themselves the heroic but probably unattainable goal of

getting every person to eat well every day. Even if obtained, such vitamin

intake as good diet provides is inadequate to maintain optimum health for

everyday people in real-life situations. Tens of millions of women have a

special concern. Oral contraceptives lower serum levels of B-vitamins,

especially B-6, plus niacin (B-3), thiamin (B-1), riboflavin (B-2), folic acid,

vitamin C and B-12. (6). Ladies, when is the last time your physician instructed

you to be sure to take supplemental vitamin C and B-complex vitamins as long as

you are on the Pill?

 

Furthermore, government vitamin recommendations are so low as to resemble a test

so easy, a standard so minimal, that you would think no one can possibly fail.

For example, the US Reference Daily Intake (RDI) for vitamin E is 30

International Units. It is widely appreciated that at least 100 IU of vitamin E

(and probably 400 IU or more) daily is required to prevent a great deal of

cardiovascular and other disease. Yet it is literally impossible to obtain 100

IU of vitamin E from even the most perfectly planned diet.

 

To demonstrate this, I've challenged my nutrition students to create a few days

of " balanced " meals, using the food composition tables in any nutrition

textbook, to achieve 100 IU of vitamin E per day. They could attempt their

objective with any combination of foods and any plausible number of portions of

each food. The only limitation was that they had to design meals that a person

would actually be willing to eat. As this ruled out prescribing whole grains by

the pound and vegetable oils by the cup, they could not do it. Nor can the

general public. Most people do not even get 30 IU of vitamin E a day. In fact,

most get only 17 IU. (7)

 

" Supplements " by definition are designed to fill nutritional gaps in a bad diet.

They fill in what may be surprisingly large gaps in a good diet as well. In the

case of vitamin E, doing so is likely to save millions of lives. The New England

Journal of Medicine had two articles in the May 20, 1993 issue (8,9) showing

that persons taking vitamin E supplements had an approximately 40% reduction in

cardiovascular disease. Nearly 40,000 men and 87,000 women took part in the

studies. The more vitamin E they took, and the longer they took it, the less

cardiovascular disease they experienced.

 

A 1996 double-blind, placebo-controlled study of 2,002 patients with clogged

arteries demonstrated a 77% decreased risk of heart attack in those taking 400

to 800 IU of vitamin E. (10) Again, such effective quantities of vitamin E

positively cannot be obtained from diet alone. 800 IU is 2,667% of the US RDI

for vitamin E. Is that a lot, or is the government recommendation too low?

 

Even a modest quantity of vitamin C prevents disease and saves lives. Just 500

mg daily results in a 42 percent lower risk of death from heart disease and a 35

percent lower risk of death from any cause. (11) Since two-thirds of the

population is not eating sufficient fruits and vegetables, the only way to close

the gap is with vitamin supplements.

 

To illustrate how extraordinarily important supplements are to persons with a

questionable diet, consider this: Children who eat hot dogs once a week double

their risk of a brain tumor. Kids eating more than twelve hot dogs a month

(that's barely three hot dogs a week) have nearly ten times the risk of leukemia

as children who ate none. (12) However, hot-dog eating children taking

supplemental vitamins were shown to have a reduced risk of cancer. (13) It is

curious that, while theorizing many " potential " dangers of vitamins, the media

often choose to ignore the very real cancer-prevention benefits of

supplementation.

 

Critics also fail to point out how economical supplements are. For low-income

households, taking a two-cent vitamin C tablet and a three-cent multivitamin,

readily obtainable from any Wal-Mart or discount store, is vastly cheaper than

getting those vitamins by eating right. The uncomfortable truth is that it is

often less expensive to supplement than to buy nutritious food, especially

out-of-season fresh produce. And those who wish to follow Linus Pauling's

perennially wise recommendation to take daily multi-gram doses of vitamin C can

do so easily and cheaply. Few people can afford to eat several dozen oranges a

day.

 

Since the ancient Egyptians, through the time of Hippocrates, and right up to

the present, poor diet has been described and decried by physicians. Little has

changed for the better, and much has changed for the worse. Though nutritionists

place a nearly Puritanical emphasis on food selection as our vitamin source,

everyone else eats because they are hungry, because it makes them feel better,

and because it gives such hedonistic pleasure. No one likes the " food police. "

Telling people what they should do is rarely an unqualified success, and with

something as intensely personal as food, well, good luck. We could, of course,

legislate Good Food Laws and make it against the law to make, sell, or eat junk.

That is as likely to work as Prohibition. It presents me with novel images of

seven-year-olds bootlegging Kool-Aid and their parents running Twinkies across

state lines.

 

Our somewhat less draconian choice of " noble experiment " has been to educate, to

implore, and to exhort the citizenry to be " choosy chewers, " to " eat a balanced

diet " and follow the food groups charts. The result? Obesity is more prevalent

and cancer is no less prevalent. Cardiovascular disease is still the number one

killer of men and women. " Health is the fastest growing failing business in

western civilization, " writes Emanuel Cheraskin, M.D., in Human Health and

Homeostasis. (14) " We can say with reasonable certainty that only about six

percent of the adult population can qualify as 'clinically' healthy. " (p 9) We

can try to sort out each of the many negative behavior variables (such as

smoking) which certainly must be factored in. When we have done so, we are left

with the completely unavoidable conclusion that our dinner tables are killing

us.

 

The good diet vs. supplement controversy may be reduced to four logical choices:

 

a) Shall we eat right and take supplements and be healthy?

 

b) Or, shall we eat right and take no supplements, be vitamin E and C deficient

for our entire lifespan, and greatly increase our risk of sickness and death at

any age?

 

c) Or, shall we eat wrong and take no supplements, and be even worse off?

 

d) Or, shall we eat wrong, but take daily vitamin supplements, and be a lot less

sickly than if we did not take supplements?

 

While each of these four options constitutes a popular choice, there is one best

health-promoting conclusion: Supplements make any dietary lifestyle, whether

good or bad, significantly better. Supplements are an easy, practical

entry-level better-nutrition solution for the public. A television-educated

populace is more likely to take some tablets than to eat organ meats, wheat

germ, bean sprouts and ample vegetables. Media supplement-scare-stories

notwithstanding, taking supplements is not the problem; it is a solution.

Malnutrition is the problem.

 

In 1998, the American Association of Poison Control Centers' Toxic Exposure

Surveillance System reported the following fatalities from vitamin supplements:

 

Adult multiple vitamins: 0

 

Pediatric multiple vitamins: 0

 

(And, incidentally, there were no deaths from vitamin C, vitamin E, folic acid,

nor from any other vitamin whatsoever.) (15)

 

On the other hand, according to David DeRose, M.D., M.P.H., " 300,000 Americans

die annually from poor nutrition choices. " (16)

 

As it has been for thousands of years of human history, so the malnutrition

problem remains with us today. Only in the last century have supplements even

been available. Their continued use represents a true public health breakthrough

on a par with clean drinking water and sanitary sewers, and can be expected to

save as many lives. But as long as USDA Food Stamps may be used to buy a box of

doughnuts, but are not allowed by law to be used to buy multivitamins, there is

a task in front of us. Vitamin supplements, like air bags, can save lives. We

should advocate them without ceasing.
