As private practicing Dietitians we learn more about the types of diets floating around from our clients than anywhere else. Similarly to clothing – there are fads and trends in eating too. One of the latest to catch our attention is the “acid-alkaline” diet. I recently heard it being discussed on radio – and then I knew the trend was really growing when my mom pulled out her “pH balance” sticks and told me to give it a go.
The first thing I would like to clear up is the statement often heard “I am very acidic” or “I have very acidic blood”. The most your blood pH level is going to vary is between 7.35 and 7.45. Blood pH is maintained despite enormous acid loads from the foods you may be eating. Your body is a hard working machine that sends messages to your kidneys and lungs that make sure the pH level stays put.
Your urinary pH is something else – this is variable, it can be more acidic or alkaline and it is affected by the foods we eat. There is often confusion regarding the foods that will make your urine acidic and the blame is usually lumped on lemons and tomatoes. Interestingly it is not these – but rather excessive dietary protein that is the main source of dietary acid load. When this is not balanced with alkaline producing foods (plant-based foods), it can result in acidosis.
Acidosis has been linked to hypertension, insulin resistance, low immune function and osteoporosis. Use the list below to help you find a balance between acidic and alkaline producing foods in your diet.
