We’ve been told our whole lives to eat certain fruits, vegetables, and whole grains to stay in good health. However, according to Dr. Steven Gundry — a world-renowned heart surgeon — many so called “health foods” in the American diet contain a dangerous toxin, that could be expanding your waistline. “This toxin causes micro-tears to form in your fragile intestinal-wall — allowing bacteria and waste products to seep into your body.” Says Dr. Gundry. This harmful condition is best known as “leaky gut,” and it’s affecting millions of people nationwide. Warning signs include weight gain, fatigue, digestive discomfort, stiff, achy joints, and even skin problems.
