I’m not overweight and I exercise regularly. So why would eating whole wheat bread be bad for me?
A: You can trigger effects you don’t perceive. Small low-density lipoprotein [LDL] particles form when you’re eating lots of carbohydrates, and they are responsible for atherosclerotic plaque, which in turn triggers heart disease and stroke. So even if you’re a slender, vigorous, healthy person, you’re still triggering the formation of small LDL particles. And second, carbohydrates increase your blood sugars, which cause this process of glycation, that is, the glucose modification of proteins. If I glycate the proteins in my eyes, I get cataracts. If I glycate the cartilage of my knees and hips, I get arthritis. If I glycate small LDL, I’m more prone to atherosclerosis. So it’s a twofold effect.
