...affects the heart. The University of Oklahoma's Dr. Stewart Wolf led a team of cardiologists into the little Pennsylvania town of Roseto, where 95% of the 1,600 inhabitants are descended from a single group of immigrants from Italy. They eat heavily, including plenty of saturated fat, and drink a lot of wine. Nearly all of them are overweight. But to their surprise the doctors found that in seven years no Roseto men under 47 died of heart attacks, and in later life their rate was barely half that in neighboring towns. Perhaps, the investigators say, the explanation...
...driving go-getter, he says, cannot clear his bloodstream fast enough of the triglycerides which accumulate after a high-fat meal. Unlike the more placid man, the go-getter uses too much of his body's heparin to break up the fat. There is not enough heparin (nature's anticoagulant) left to keep the red blood cells apart: "If, after every meal, a man has too many fat particles going around and red cells sludging and obstructing small blood vessels, the heart may be temporarily so embarrassed that this man will have a heart attack without a clot...
...Chemists call a fat saturated if each carbon atom along the molecular chain has hydrogen atoms attached. It is monounsaturated if one carbon atom is free of the hydrogen bonds; it is polyunsaturated if two or more are free. *Amid a plethora of diet books, a new edition of Jolliffe's Reduce and Stay Reduced on the Prudent Diet (Simon & Schuster; $4.95) is the biggest seller...
...Fat Theory. The PHS withdrew its claims about the menhaden, which left about 175,000 fresh-water fish believed to have died of endrin. But how did the poison get into the fish while the water in which they lived was essentially free of endrin? The PHS believes fish gradually concentrate the insecticide, which lodges in their fat. When the fish consume their fat in time of food scarcity, enough endrin is released into their blood to kill them...
Mining in Canada seems to follow a pattern of seven years of fat, seven years of lean. The great uranium boom pumped $10 billion into the Canadian economy between 1950 and 1957, then fizzled. Now, after seven fairly slender years, a new mining rush is on. Some 900 companies are drilling for metals and oil from New Brunswick to British Columbia...
