Here's a new report which at least seems to support this claim (which is so common these days):
"A diet high in refined carbohydrates, like white rice or white bread, is associated with increased prostate tumor growth in mice.
Having too much insulin in the blood, a condition called hyperinsulinemia, is associated with poorer outcomes in patients with prostate cancer..."
Do you see the problem here? They are making it sound like any diet rich in "refined carbohydrates" (or as so many now say, "simple carbs") is problematic in this context. Let us leave aside the fact that this does not mean the tumor was caused by simple carbs, and focus instead on the fact that what they really found was that hyperinsulinemia is the problem. They then assumed that any diet rich in simple carbs causes this condition to occur. The reality appears to be very different, and Spindler's caloric restriction experiments showed (he found that the CR animals had an intense insulin spike when they ate, but that insulin levels went right back down to healthy levels). Thus, it may be the case that "complex carbs" are healthier in this one context at least, but only if you are eating a certain way ("the American way"). If you don't eat way too many calories, if you eat three meals a day only (spaced out evenly) with no other episodes of caloric intake, and if you eat enough high-quality protein (and don't eat too much UFAs or oxidized cholesterol), then it seems to be the case that "simple carbs" are fine, and won't cause the intestinal issues and won't have the anti-nutritive qualities that "complex carbs" do. I've certainly found this to be the case in my personal dietary experiments.
