Diet Affects Prostate Cancer Risk
The prospective Malmo Diet and Cancer study followed
8128 healthy men, aged 45-73, for 15 years and found no
association of prostate cancer with total carbohydrate or fiber
intake. It did find an association of prostate cancer with
refined carbohydrates in foods such as low-fiber cereals, cakes,
biscuits, white rice and pasta. (American Journal of Clinical
Nature packages all carbohydrates in foods with fiber.
After you eat, the pyloric sphincter at the end of the stomach
closes and allows only a liquid soup to pass into the intestines.
Since humans cannot break down fiber, it takes a long time for
fiber to pass into the intestines. Removing fiber from nature's
sources of carbohydrates increases the rate of absorption and
raises blood sugar levels considerably. It takes an orange up
to six hours to pass through your stomach, compared to minutes for
orange juice (liquid sugar) to pass. The higher blood sugar rises
after you eat, the more sugar sticks to the outer membranes of
cells and damages them, which can increase cancer risk.
The same applies to whole grains and flour. Whole grains
are seeds of grass that have a tight capsule that cannot be broken
down by your intestinal enzymes. Therefore, eating whole grains
causes very little rise in blood sugar. However, grinding a whole
grain into flour breaks the capsule and markedly increases the
rise in blood sugar that follows eating bakery products or pastas.
This high rise in blood sugar is probably what increased the men's
risk for prostate cancer.
