When the body eats foods, the digestive and metabolic processes transforms the eaten matter into residue that is left behind that is either acidic or alkaline. Using science to explain this phenomenon (and the laws of modern biochemistry), it is not the organic matter of foods (whether the food itself is acidic or alkaline), but their inorganic matter (such as calcium, magnesium, potassium, sodium, sulfur, phosphorous; that is, how they break down in our bodies), that determines either the acidity or alkalinity of this ashy residue. Being too acidic promotes disease, chronic ailments, cancer and other health complications. Intentional alkalizing of the body blood and other fluids optimizes healthy organ and system functioning, free of ailments. Factors that leave our bodies acidic include environmental pollutants, acid-forming foods like processed sugars and foods, artificial sweeteners, refined grains, conventionally produced meats and dairy, hidden genetically modified organisms (GMOs), psychological and emotional stress, synthetic and pharmaceutical drugs and physical body stress. Consider the following lists to be the nutrition bible of top alkalizing and acidic foods to eat and avoid for optimum health functioning, free of chronic disease.
