Although it is difficult to find hard evidence that an alkaline forming diet is better for you, there is some initial evidence starting to grow indicating that a diet low in acid forming foods like animal based proteins such as meat and cheese and high in fruit and veggies will help to prevent kidney stones, keep bones and muscles strong, improve heart health and brain function, reduce low back pain and lower the risk of colon cancer and type 2 diabetes(see www.webmd.com). Kind of makes sense if you have a look at the list of alkaline forming foods versus acid forming foods. If you are really interested in following this diet protocol then monitoring your urine Ph at same time each day with the use of litmus paper might help you keep track of your blood Ph. Finally some schools of thought recommend a dietary balance of 80:20, alkaline v acid.
