Acid – Alkaline Foods


Foods can be classified as acid or alkaline, not according to taste but to the residue left after the food has been digested and used by the body.


The blood of human beings has a normal pH (Acid-Alkaline balance) of 7.41 which is fairly stable. When this shifts e.g., when there is a change in a person's breathing or the rate at which
food is converted to energy, the body attempts to correct the acid-alkaline balance. The theory behind the benefits of the popular alkaline diet is that some foods, like meat, wheat, refined
sugar, and processed foods, cause your body to produce acid, which is not healthy. It has been proposed that eating alkaline foods can help you lose weight and avoid problems like arthritis
and cancer. More research is needed to prove this theory, however, following an alkaline diet is certainly good for you. Alkaline foods include lots of fruits and vegetables, and water while
avoiding sugar, alcohol, and processed foods.

There is some early evidence that a diet low in acid-producing foods like animal protein (such as meat and cheese) and bread and high in fruits and veggies could help prevent kidney stones,
keep bones and muscles strong, improve heart health and brain function, reduce low back pain, and lower risk for colon cancer and type 2 diabetes.
