The French outlive Americans by about two and a half years (76.5 versus 74) and suffer 40 percent fewer heart attacks despite the fact that Gauloise smoking is a national pastime, their diet swims in a torrent of fat and the average Gaul speaks the language of Nautilus, StairStepper - and aerobics about as well as English (or any other barbarian tongue). Despite all our billions spent on health care, and the sweat and the self denial, and the bland health food diets, we still die younger. And some would say that at the end of this journey, we didn't enjoy the scenery nearly as much as the average French peasant.
This situation has been dubbed "The French Paradox" and was made famous in November 1991, when CBS's Morley Safer explored the matter on an episode of 60 Minutes.
In reality, the whole bubbling cauldron of contradictions should be labeled "The American Paradox" because we have, at our everyday convenience, all of the means to match and surpass the French levels of joie de vivre and health success. But we refuse to recognize or do anything about them, partly because the answers seem too simple, partly because our health philosophy focuses on intervention rather than prevention and partly because of hysterical opposition to alcohol consumption in any quantity at all. For the reality is that health is on the plate and in the glass; it's just politically incorrect to recognize those facts.
According to Dr. R. Curtis Ellison, M.D., chief of preventive medicine and epidemiology and professor at Boston University School of Medicine, the French secret boils down to wine, food and lifestyle.
The French, Dr. Ellison says:
-- Are regular consumers of moderate amounts of alcohol, especially red wine, primarily with meals,
-- Eat more fresh fruit and vegetables,
-- Take longer to eat meals and snack less,
-- Eat less red meat,
-- Eat more cheese, less whole milk and
-- Use more olive oil and less lard or butter.
Of all these factors, Dr. Ellison said the link with moderate and regular consumption of wine with meals is the strongest and most scientifically proven.
In fact, Dr. Ellison's list is an exhortation for a "back to the future" approach to dietary health which embraces more traditional, healthier cuisines (and their associated moderate wine consumption). We shouldn't rely on processed "techno-foods" like Simplesse, Nutrasweet, MacLean Burgers and "Lite" foods which manufacturers have manipulated beyond recognition in order to make them "healthier."
Greg Drescher, a director of the Massachusetts-based Oldways Preservation and Exchange Trust (which is dedicated to preserving traditional cuisines), draws an analogy between techno-foods and methadone: "We don't know where we're going with that approach; the cure may be worse than the disease," he said. "Techno-food could prove dangerous." By contrast, he says traditional cuisines are tried and true sources of health.
One of the first San Francisco Bay Area restaurants to put the traditional ways into practice was Chez Panisse which, for more than 20 years, has emphasized fresh, natural and organic ingredients -- but all without throwing the health aspects in the diner's face.
"I don't want to interfere with people," says owner and chef Alice Waters, "telling them, `you are eating politically correct biologically wholesome food.' It gets tedious."
But traditional cuisines are coming under commercial pressure not only in fast/frozen/processed/manufactured/techno-food America, but in the very cradle of healthy cuisine -- France and the Mediterranean. The British magazine, New Scientist, reports that a European food industry research firm, Leatherhead Food Research Association is offering for sale an expensive study that identifies opportunities for selling processed foods to consumers in the Mediterranean countries.
"There is considerable potential for manufactured food products in Italy, Spain, Portugal and Greece," said a Leatherhead news release. "And there is already a definite trend towards processed and convenience foods at the expense of the fresh sector."
It is ironic then that the first broadside fired in defense of traditional French cuisine came from the big guns of American television, 60 Minutes; and that the concept would be kept alive by the American wine industry which is mounting a massive publicity campaign to promote the health benefits of wine and French/Mediterranean food culture. Americans in defense of French culture? Mon Dieu! The American paradox continues.
During that segment on 60 Minutes, Dr. Serge Renaud, M.D., head of the Lyon center of INSERM (the French equivalent of our National Institutes of Health) said, "It's well documented that a moderate intake of alcohol prevents coronary heart disease by as much as 50 percent."
Dr. Renaud's assertion is backed by scores of university and hospital studies, conducted at places like Harvard and Cornell, and published in such respected publications as the Journal of the American Medical Association, The American Journal of Cardiology and the leading British medical journal, Lancet. Some of the studies are as recent as 1992 and others date back to the mid-1920s.
But what is moderate? According to Dr. Keith Marton, M.D., chairman of the Department of Medicine at the California Pacific Medical Center and a professor at the University of California, San Francisco Medical School, "moderate" consumption is generally defined as 25 grams of pure alcohol per day, the equivalent to two or two and a half, 4-ounce glasses of wine per day.
The most recent study headed by Eric Rimm at the Harvard School of Public Health found cardiac protection at levels as high as 50 grams per day, although at the higher limits they also reported an increased risk of liver disease and of some cancers.
In fact, statistics pointing to these increases are often cited by alcohol control groups as reasons why people should not drink any alcohol. However, Dr. Ellison said that in essentially all studies, moderate drinkers have a significantly lower death rate (usually 20 to 40 percent less) from all causes than abstainers and even lower rates than heavy (5 to 6 drinks per day) drinkers. Dr. Ellison said that while the research is not conclusive, increased cancers and liver disease are associated with "especially heavy drinking and alcohol abuse but generally not increased with moderate wine consumption."
The reason for this is the relative rarity of liver disease compared with coronary artery disease. The World Health Organization's 1989 World Health Statistics Annual found in the United States that the death rate from cirrhosis of the liver was 17 per 100,000 while cardiovascular disease killed 464 per 100,000. By contrast, the same study shows France with almost double the cirrhosis rate -- 31 per 100,000 -- but with cardiovascular rates at only 310 per 100,000.
Using these figures, it is not hard to see that if the U.S. rates were normalized with those of France, 14 more people per 100,000 would die of cirrhosis, but 154 fewer people would die of cardiovascular disease. a net savings of 140 people per 100,000 population who would live longer in order to die later of something else (for, after all, the death rate is eventually 100 percent).
In fact the statistics also hide a striking pattern in the French cirrhosis rates. Dr. Renaud said that INSERM studied the rates on a regional basis and found the highest cirrhosis rates (50 to 100 per 100,000) in the northern regions of Alsace and Lorraine which have the highest consumption of beer and spirits.
However, the locales with the highest wine consumption, such as Provence and other wine producing regions which consume less beer and spirits, had the lowest cirrhosis rates -- 7 to 14 per 100,000 -- putting them even lower than the U.S.
Some people have questioned the wine versus other alcoholic beverages figures on socioeconomic grounds; research indicates that, at least in, America, wine drinkers are better-educated, earn more money and are in a better position to eat healthier and get better medical care.
However, animal studies with rabbits have shown the same sort and degree of protective effects of alcohol as human studies. In a study published by researchers Klurfeld and Krischevsky in the Journal of Experimental and Molecular Pathology, the following effects were observed (see next page):
As with cirrhosis, the increased risk of cancers, said Dr. Ellison, also seems connected more with abuse than with moderate use. In fact, red wine contains quercetin, a compound also found in garlic and onions which has been proven to exhibit strong anti-cancer effects. The research, however, is not yet advanced enough to draw any conclusions with regard to quercetin in wine.
There may be some connection between moderate alcohol consumption and an increase in breast cancer. According to Dr. Marton, a review of 24 major studies shows 12 finding no association between moderate consumption and breast cancer, and 12 which indicate there may be as much as a 4 percent increase in the lifetime risk of breast cancer. "Many of these studies," Dr. Marton said, "do not account for other factors (other than alcohol) that might affect the risk of cancer."
However, Dr. Marton said that even if you accept the worst-case studies as valid, a woman who drinks moderately must balance the 4 percent increase in the risk of getting breast cancer against the 10 to 20 percent decrease in risk of dying of heart disease - - a net positive effect of 6 to 14 percent.
"There's no other drug that is so efficient (at preventing heart disease) as moderate intake of alcohol," said Dr. Renaud, who cautions against excessive consumption. "It has to be given at a proper dosage."
Such proper dosages, according to Dr. Ellison, could produce this protective effect by increasing HDL lipoproteins (the "good" cholesterol) and decreasing LDL lipoproteins (the "bad" cholesterol). In addition, he said research also shows that alcohol decreases the tendency of blood to clot in arteries and increases fibrinolysis is -- the ability to dissolve clots once they have formed.
In addition, he feels that three other factors may also contribute to alcohol's protective role. These possible (and he repeatedly emphasizes `possible',) mechanisms may be that moderate alcohol consumption:
-- Reduces the tendency of arteries to constrict during stress which decreases blood flow,
-- Lowers blood pressure and
-- Increases coronary artery diameter and blood flow.
But wine alone may not explain the French Paradox entirely. Dr. Ellison and others believe that the French diet may also play a substantial role.
The French eat more fresh fruits and vegetables which are fresher than American equivalents and more often consumed raw or with minimum cooking. This, Dr. Ellison and others feel, preserves vitamins that act as anti-oxidants which not only decrease the development of atherosclerosis (clogging/hardening of the arteries) but may also retard cancer development.
In addition, the French take more time with their meals which is not only a possible stress reducer, but may affect the absorption and metabolism of fats, insulin levels or the effects of fats on blood clotting.
Snacks also play a smaller dietary role in France. Dr. Ellison said that in a recent study he found that the French averaged 7.5 percent of their daily calories from snacks while Americans averaged 21 percent. This figure may be aggravated by high-fat American snacks and techno-foods.
The French diet also contains smaller portions of red meat which has much less fat than American meat.
Dairy food consumption also differs strikingly from the American patterns. The French consume their dairy products in the form of cheese, rather than whole milk. Dr. Renaud said his research indicates that the calcium in cheese may bind to the fat, making it less likely to be absorbed by the body. No such binding effect has been observed in whole milk, he said.
In addition to dairy fat, the French use more olive oil and goose fat than butter, lard or other animal fats. "This is most true in the south of France where heart disease is particularly uncommon," said Dr. Ellison. "Numerous studies have shown that olive oil is less atherogenic [less likely to cause hardening of the arteries]," he added. "Some French research shows that goose fat -- such as that found in foie gras -- may be less atherogenic since it contains more monounsaturated fats than other animal fats."
The role of dietary fat in the French Paradox has become somewhat controversial. One nutritionist, Marion Nestle, chair of the New York University Department of Nutrition, Food and Hotel Management, asserts that the data on lower French heart disease rates comes from a time period when the French were eating less fat than Americans and this accounts for much of their lower cardiovascular death rates; thus there is no paradox at all.
Nestle uses food supply data from the U.N.'s Food and Agriculture Organization (FAO) to support her claims. The supply numbers, she said, are produced by taking food production statistics, subtracting exports, adding imports and then dividing by the population to produce a per-capita consumption figure.
She said that these data indicate that the French diet has only caught up with the Americans' in the past decade. In 1961, she said, the French ate 28 percent of their calories from fat, increasing to 30 percent in 1965, to 34 percent in 1975, to 37 percent in 1985 and to 39 percent in 1988. By contrast, Americans first consumed 35 percent of their dietary calories from fat in 1923 and hit 42 percent in 1988.
Nestle admitted that the food production number is "not an absolutely accurate indicator of what people are actually eating" but that it provides a method which can be consistently applied over a period of many years. She said that variations in the methods of measuring actual consumption prevent this consistent approach.
Drs. Ellison and Renaud say they have based their research and calculations on (among many sources) actual consumption figures developed by the World Health Organization's (WHO) MONICA Project and feel that their numbers are sound.
This disagreement in historical data is important because several studies indicate that atherosclerosis may begin in early childhood. Thus, a 50-year-old's 1992 heart attack may have its roots in 1942. But researchers have not yet reconciled this data with numerous studies which indicate that switching to healthier, low-fat diets can affect the course of heart disease for people in their 40s and older. This means that even with a worst-case interpretation of the statistics, the French Paradox may be providing at least partial protection.
There is, however, no disagreement among the experts that the French traditional cuisine and wine consumption habits are eroding and becoming more like Americans. What's more, genetic factors cannot protect them from the ravages of techno-food, stress and unsound diets.
Drs. Ellison and Renaud (along with other researchers) say that while genetic factors are important in determining an individual's risk of heart disease, they apparently are not a factor in explaining the French Paradox. They cite numerous studies that show that people from the Mediterranean and other countries who immigrate to the U.S. soon lose the protective advantages of their native cuisine and lifestyles and begin suffering from the same dietary-related diseases that afflict Americans once they start to eat like Americans. Thus, as the French begin to eat more like Americans, they will begin to die like Americans -- increasingly of cardiovascular disease.
But, Dr. Ellison cautions, Americans shouldn't rush out and gorge themselves on wine and pate. Moderation, he cautions, is key. In addition, he said that American efforts to cut down on fats, eliminate smoking and engage in exercise should remain priorities. The key is not to adopt a new style of eating just for the sake of health, but because it tastes good and provides pleasure.
Dr. Ellison and others say that the pressures to be healthier -- to exercise, diet and eat right, no matter what -- may produce unhealthy stresses of their own.
The tasty, enjoyable aspects of the healthy French way of eating are well illustrated by Peter Mayle, an English author and journalist who turned his back on his fat- and sugar-heavy native cuisine. In Toujours Provence (the sequel to A Year In Provence), Mayle writes of the seemingly limitless drinking of wine and pastis and says,
`It is impossible to live in France for any length of time and stay immune from the national enthusiasm for food, and who would want to? Why not make a daily pleasure out of a daily necessity? We have slipped into the gastronomic rhythm of Provence, taking advantage of the special offers provided by nature all through the year ... Meat everyday is a habit of the past. There is so much else: fish from the Mediterranean, fresh pasta, limitless recipes for those vegetables, breads, hundreds of cheeses.
"It may be the change in our diet and the way it is cooked, always in olive oil, but we have both lost weight."
Finally, a group of British scientists, who found protective effects from moderate wine consumption wrote in the respected British medical journal Lancet, "If wine is ever found to contain a constituent protective against IHD (ischemic heart disease) then we consider it almost a sacrilege that this constituent be isolated. The medicine is already in a highly palatable form."
