Wheat + Villi
The information that struck me most about wheat, when I first quit eating it in my early 20s (long before GF products were dreamt of) was that the abrasion could actually permanently damage the villi of the small intestines, reducing the vast surface area of the small intestines (250 square meters or a tennis court) and your potential for absorbency. Unless you have celiac disease, healing and reversing villous atrophy can take up to 2 years – depending on your diet and ‘age’. ??
