GI Disorders. Studies show that the lectins in grains inflame the lining of the gut and create fissures between cells. Also, when whole-kernel grains are refined, 80 percent of the fiber is lost, and gut health suffers. “Without the fiber, you end up with rapid-release carbs in these grains, which is a bad thing for the gut,” says Kathie Swift, MS, RD, coauthor (with Mullin) of The Inside Tract. Plus, fiber helps sweep the gut of debris and supports the body’s critically important elimination and detoxification processes, which also play a role in keeping high cholesterol and inflammation at bay.
Food Allergies/Intolerances. Wheat, in particular, is one of the biggest dietary triggers of food allergies and intolerances. While the exact reason is unclear, many experts blame the higher gluten content of modern wheat varieties. A type of protein found in many grains, including wheat, gluten gives dough elasticity, trapping air bubbles and creating a soft texture. Because soft is considered desirable, wheat today is bred to have more gluten than ever before.
Acid-Alkaline Imbalance. The body has an elaborate system of checks and balances to keep its pH level at a steady 7.4. A diet high in acidic foods, such as grains, forces the body to pull calcium from the bones to keep things on an even keel. When researchers looked at how the diets of more than 500 women affected their bone density, they found that a diet high in refined grains, among other nutrient-poor foods, was linked to bone loss. A highly acidic diet also chips away at our cellular vitality and immunity in ways that can make us vulnerable to chronic disease. “Grains are the only plant foods that generate acidic byproducts,” says Davis. “Wheat, in particular, is among the most potent sources of sulfuric acid, a powerful substance that quickly overcomes the neutralizing effects of alkaline bases.”
