Are corn, rice, and potatoes any better?
Yes, they are, but not by much. Corn, rice, and potatoes do not stimulate appetite to the same degree as wheat, nor do they seem to exert the same addictive effects as crackers, pretzels, and breads. However, they do raise blood sugar nearly the same amount and can thereby trigger many of the same undesirable health consequences like increased triglycerides, low HDL, small LDL, higher blood pressure. From a practical viewpoint, however, I find that the majority─perhaps 90%─of the problem in diet nowadays is not rice, corn, or potatoes, but wheat. It is not uncommon for people to indulge in wheat products five times per day. It’s very unusual, however, for someone to eat corn, rice, or potatoes five times per day. Just addressing the wheat issue usually leads to substantial improvements in health, even if a bit of corn, rice, or potatoes is still included.
