The New Four Food Groups

We’ll conclude this section with the results from a surprising experiment
conducted at the University of California at Los Angeles. Researchers
drew blood samples from a group of men who had been following a lowfat diet and exercising regularly for several years. They also drew blood samples from overweight men who were not following any diet or exercise program. They then added portions of each man’s blood serum to test tubes containing
standardized prostate cancer cells. It turned out that serum from men on the low-fat diet and exercise program slowed cancer cell growth by 49 percent compared to serum from the other men. The changes in diet and exercise had caused the amount of testosterone, estrogen, and other components in the blood to change so dramatically that the effect on cancer cells was obvious right in the test tube.10

The effect occurs quickly. The research team found cancer-inhibiting
power within as little as eleven days after beginning a low-fat diet and exercise
regimen.11

Cutting down on fat is an important first step in preventing cancer and
in surviving it if it has been diagnosed. So how do we go about it? The easiest
way is to build your meals from foods that are naturally low in fat and
to use cooking methods that don’t require you to add fats or oils.
