...South Atlantic last October when a long-dormant volcano poured a river of molten rock toward their thatch-roofed houses. In traveling 6,500 miles to safety in England, they moved nearly a hundred years forward in time. At home, they had lived on a fish-and-potato diet, carded and spun wool by the light of oil lamps, ridden in bullock carts. In their new cottages near the British port of Southampton, they encountered for the first time the 20th century wonders of electric light, store clothes, supermarkets, frozen foods and traffic jams...
...with a lot of cholesterol in their blood tend to have heart attacks earlier in life than others. Though some foods contain readymade cholesterol, the body manufactures more of it from saturated fats in meat and dairy products. So the argument runs: Cut down on saturated fats in the diet, thus lowering the cholesterol level in the blood and reducing the danger of artery disease and heart attacks...
...cannot be taken for granted," Dr. Master told the American Medical Association, "as many physicians and lay persons do, that lowering the blood cholesterol will reduce the incidence and mortality of coronary disease and coronary thrombosis. There is as yet no proof that a diet low in saturated fats, or a drop in the blood cholesterol, will prevent or in fluence coronary disease."

Some doctors have urged simply cutting down fats, of whatever kind, to about 30% of the total caloric intake. Others have advocated substituting polyunsaturated fat for much of the saturated stuff, and worrying less about the total intake. Conservative...
Point of Desperation. Many factors beside the quantities of food and fats consumed are important in regulating the body's cholesterol level. So Dr. Master deplores overemphasis on diet. "We have encountered people who have deprived themselves of foods they crave, almost to the point of desperation," report Dr. Master and his colleague, Dr. Harry L. Jaffe. To avoid this situation, and to help their patients achieve "philosophical equanimity," they encourage people to relax and enjoy moderate amounts of butter and cream, meat and eggs. This is no different from Grandma's injunction to eat "everything in moderation...
