We Are What We Eat We can now balance the food to match your blood type. The blood contains antigens. The antigens in the food must match the antigens in the blood. The digestion of food and the elimination of waste products are cornerstones of well-being. If impaired, the body can be deprived of essential nutrients and become overloaded with toxins. Most of us know that food itself can not be considered poisonous. Very few of us know that bacteria, yeast, and fungus and their toxins, which are characteristically present in stored and fermented foods, are using our food chain as a Trojan Horse. This only brings about disease in the body. A proper diet and low stress levels are vital to healthy functioning of the digestive and excretory systems.
