...HEART More confusion for women on hormone-replacement therapy: a second look at data released two years ago about women with heart disease suggests that estrogen and progestin may slightly lower the risk of heart attack among subjects with high levels of a form of cholesterol called lipoprotein-a. In women with normal or low levels of the cholesterol, however, the hormones seemed to raise the heart-attack risk. You should probably discuss this latest hormone dilemma with your doctor--and stand by for more conclusive data...
...means peanut butter would classify as a trans-fat-free food. The majority of fats in peanuts and peanut butter are heart-healthy mono- and polyunsaturated fats. Also, a study at Penn State found that a diet rich in peanuts and peanut butter significantly lowers total and low-density-lipoprotein cholesterol. In addition, large population studies now show that eating peanuts, other nuts and peanut butter five or more times a week can cut the risk of heart disease as much as 50%.

Most worrisome, my LDL level (the so-called bad cholesterol, but actually low-density lipoprotein, which helps maintain cholesterol in the blood) is high at 148 compared with my "good" HDL (high-density lipoprotein, which helps clear cholesterol), which is 54. Moore assures me I can lower my cholesterol without medication and asks about my diet. While I generally stay away from red meat and eat mostly fish, chicken, vegetables and salads, I confess a weakness for cheese, potato chips and butter on all sorts of things. Moore wonders if I am ready to "commit"--as she says--to eliminating...
...good cholesterol" you hope will turn up in your blood test has that name for a reason. More properly known as high-density lipoprotein (HDL), it can prevent the damage done by its evil twin, low-density lipoprotein (LDL). The latter clogs blood vessels by combining with oxygen to form a substance that sets off alarms in the immune system. White blood cells rush to attack it, and the whole mess forms into sticky globs called plaques that cling to vessel walls like mineral deposits in a water pipe. When these deposits break off and blood clots around them...
...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...
