...study of 50 black and 219 white physicians, who presumably have access to care and can make improvements in their diet, researchers found a marked difference in the ability to handle cholesterol. Compared with their white colleagues, the black physicians exhibited higher blood levels of a type of lipoprotein believed to aggravate blockage of coronary arteries. Other research found that elderly black men are twice as likely to develop tuberculosis as white men living under the same socioeconomic conditions. Perhaps, scientists speculated, genetic differences affected the body's ability to knock out the bacteria...
...level of saturated fat, in contrast to 14% in olive oil and 51% in palm oil. Canola also contains high levels of monounsaturated fat. For a number of years, consuming that substance was thought to reduce the "bad" type of cholesterol in the blood known as LDL (low-density lipoprotein). Recent studies suggest, however, that monounsaturated fat has no special power but is valuable as a replacement for damaging saturated fats...
...current craze stems from studies showing that oats, particularly oat bran, can have a salutary effect on blood levels of total cholesterol and, even better, of the "bad" type of cholesterol known as LDL (low-density lipoprotein). Researchers have found that consuming 1 1/2 to 3 oz. of oat bran daily for six to eight weeks can lower total cholesterol some 20% and LDLs as much as 25%. "It's great stuff," says Dr. James Anderson of the University of Kentucky, who pioneered the study of oat bran in the 1970s. Anderson estimates that up to 85% of Americans with...
...from 200 to 239 mg/dl are viewed as borderline cases and advised to watch their diet and be retested annually. Individuals with levels of 240 mg/dl or more are at high risk and require medical attention, including a second test to determine the ratio of "good" cholesterol (high-density lipoprotein, or HDL) to "bad" cholesterol (low-density lipoprotein, or LDL). People in the borderline range who have additional risk factors, such as smoking, being male, or having a family history of heart disease, are advised to follow the same routine as those at high risk...
...like lovastatin might do the job. Working with Grundy and David Bilheimer, another UTHSCD researcher, they tried it in 1982 on six patients. Within a few weeks, blood-cholesterol levels had dropped from an average of 350 to 250. Furthermore, the drug actually boosted the amount of high-density lipoprotein (HDL), a natural substance that seems to scavenge excess cholesterol out of the bloodstream. "That study really opened people's eyes," recalls Grundy...
