...that it operates more efficiently. A 10-year study of rhesus and squirrel monkeys found that the underfed animals have lower blood pressure and better cholesterol. Perhaps the most striking finding: underfed animals look as though they will be protected from heart disease. Their levels of high-density lipoprotein -- the good cholesterol that helps keep blood flowing smoothly through the arteries -- are twice as high as in monkeys who eat a normal diet, meaning more food. The downside, of course, is that the healthier monkeys appeared to be hungry much of the time...
First the doctors were warning all of us about the artery-clogging dangers of plain old cholesterol. Then we had to start keeping track of "good cholesterol" and "bad cholesterol." Now comes the latest complication: really bad cholesterol. Its scientific name is lipoprotein(a), or Lp(a), and after years of preliminary evidence, researchers have now firmly established just how bad it is. A study published in last week's Journal of the American Medical Association says high levels of Lp(a) in the blood can double a man's risk of having a heart attack before...
When asked about how the study would affect the common perception of beer, Gaziano said, "I think most people had heard that wine drinking was good for your health, but we showed that it's alcohol from beer, wine or liquor that raises the levels of high-density lipoprotein or 'good cholesterol...
...average person, Gaziano explained that "good cholesterol" takes blood away from artery walls, thus preventing heart disease; while low-density lipoprotein or "bad cholesterol" sticks to artery walls and clogs the blood vessels...
Chances are that if the protective effect is real, then the explanation lies in vitamin E's ability to prevent oxidation of fatty compounds in the blood -- the same biochemical reaction that turns butter rancid. Researchers believe that when low-density lipoprotein, the "bad cholesterol," is oxidized, it builds up more easily on artery walls. By blocking oxidation, vitamin E may counteract some of the risk of heart attack associated with...
