Approximate pH of Foods and Food products

To assist readers in determining the product pH levels, the approximate ranges of pH values are compiled below. Considerable variation exists between varieties, condition of growing and processing methods, etc. Data is presented for the edible portion of foods in their normal and natural state, unless otherwise designated. We solicit your input to this matter. This list will be updated when new information is available. As most of you know that ph 7.0 is neutral. The higher the ph value, the more alkaline is the food and lower the value the more acidic is the food.
