The theory behind the alkaline diet is that some foods, such as meat, dairy, sugar, and processed foods, are “acid-forming” and cause the body to become more acidic.
Conversely, other foods, such as fruits, vegetables, and nuts, are considered “alkaline-forming” and help to alkalize the body.
Proponents of the diet believe that maintaining an alkaline pH level is essential for good health and can help to prevent diseases such as cancer, osteoporosis, and kidney stones.
