Eine im Journal of the American Medical
Association veröffentlichte wissenschaftliche Studie zeigt,
dass eine strikt eingehaltene, fettarme vegetarische Diät
wie sie bei unseren Vorfahren aus der Familie der Affen üblich
war das "schlechte" Cholesterin (LDL-Cholesterin) ähnlich
gut absenkt, wie die heute üblicherweise vorordneten Blutfettsenker
aus der Familie der Statine.

Diet May Cut Cholesterol As Much As Drugs
Eating a diet similar to that of our ape ancestors can have as
much of an effect on cholesterol levels as modern medicine does,
a new study suggests. Results published today in the Journal
of the American Medical Association indicate
that a strict, low-fat vegetarian diet high in specific plant
products can lower levels of bad cholesterol as much as widely
prescribed statin drugs can.
A number of foods, soy protein and oats among them, have known
cholesterol-lowering effects. David J. A. Jenkins of the
University of Toronto and his colleagues tested a specific vegetarian
diet that combined many of these food groups into one menu that
contained high amounts of plant sterols, fiber, nuts and soy protein.
Of the 46 patients with high cholesterol levels that the team
studied, 16 ate this diet for a month. A second group of 16 ate
a regular low-fat vegetarian diet and 14 participants consumed
the low-fat diet and took 20 milligrams of lovastatin, a standard
At the end of the study period, those patients who ate the special
diet lowered their levels of LDL cholesterol (the "bad"
type associated with clogging coronary arteries) by 29 percent
whereas the patients taking lovastatin reduced their LDL levels
by 31 percent. The low-fat dieters, in contrast, showed just an
8 percent decrease in the amount of LDL present. "As we age,
we tend to get raised cholesterol, which in turn increases our
risk of heart disease," Jenkins explains. "This study
shows that people now have a dietary alternative to drugs to control
their cholesterol, at least initially."
The results are still preliminary, however. Writing in an accompanying
commentary, James W. Anderson of the University of Kentucky
notes that if the findings are confirmed by larger and more rigorous
studies, they could have far-reaching implications for many patients
suffering from cholesterol problems.
He notes "those who are motivated to
adopt prudent diets might achieve meaningful lipid reductions
