First off, the Alkaline Diet is an eating plan that claims to help you drop pounds, while avoiding health problems such as cancer and arthritis. When followed correctly, your blood’s pH should remain steady or balanced. It calls for the avoidance of processed foods, caffeine, wheat, dairy, meat and eggs. The foods you can eat include legumes, tofu, soybeans, seeds, nuts and most fruits and vegetables. The Alkaline Diet dates back to the 19th century and has changed to some degree to suit different needs.
