...England Journal of Medicine indicate that the softer the margarine spread, the lower amount of LDL, or so-called "bad" cholesterol. On the other hand, the production process that results in harder margarines, called hydrogenation, introduces more trans fatty acids, which scientists believe results in a signficant reduction in HDL, so-called "good" cholesterol...
Here's what the researchers found: Both bad (LDL) and good (HDL) cholesterol levels are lowered by margarine. But softer spreads most reduce bad cholesterol (LDL) and least reduce good cholesterol; conversely, stick margarine least reduces bad cholesterol and most reduces good cholesterol. Butter ends up somewhere in the middle. If the results sound confusing, it's because they are. "Margarine apparently has some benefits," says TIME senior science writer Jeffrey Kluger, "but not as much as we once believed...
...double-blind placebo-controlled trial of 20 men, published in last week's Journal of the American Medical Association, researchers from Iowa State University found that taking andro did nothing for testosterone levels. Instead, it boosted the amount of estrogen-like compounds in the blood and decreased levels of HDL, or "good" cholesterol, by 12%. Moreover, andro did not help test subjects build muscle mass at all. Scientists want to do more research to be sure, but right now it looks as though all that androstenedione consumed by would-be sluggers after McGwire broke the home-run record may have...
...mg/dl and 240 mg/dl) who ate roughly two tablespoons of Benecol a day decreased their level of LDL, the "bad cholesterol," about 14%. The manufacturers of Take Control, on the other hand, designed their product so that it would lower LDL levels 10%. Neither spread affects the level of HDL, or "good cholesterol." Which product would work better for you, if it works at all, depends a lot on your own biochemistry...
...women are older, those heart attacks are more often fatal. This is a postmenopausal phenomenon, a trade-off for years of protection from estrogen. Staying bathed in the hormone keeps blood vessels elastic and free of hardened-plaque formations. Estrogen also instructs the liver to churn out more HDL, or good cholesterol, which pulls plaque away from artery walls...
