Alkalizing and Acidifying Food Database
I have been searching around for reliable sources for determining which foods or drinks are alkalizing or acidifying. So far, I have been finding a mixture of food placement for various sites. For instance, one site says tomatoes are alkalizing and another says they are acidifying. Initially, determining whether who is valid or what is not, we can make use of its pH level, but there are acidic foods or drinks that are actually acidifying rather than alkalizing. We have to study what each foods do when it contacts with the stomach acid.

Not knowing too much biology and forgetting most of my chemistry, I am lost till I find these two related sites:

http://dietgrail.com/lowaciddiet/
http://foodhealth.info/pral-potential-renal-acid-load/

They calculate each type of foods by dividing it up into individual components: protein, phosphorus, potassium, magnesium, and calcium. Then they use the numbers to determine a value called PRAL. A negative PRAL would imply the food or drink is alkalizing and a positive PRAL would imply it is acidifying. The equation is shown below:

PRAL = 0.49 x protein + 0.037 x phosphorus - 0.021 x potassium - 0.026 x magnesium - 0.013 x calcium

There is a research group doing all these number crunching for a lot of variety of foods. I am not sure whether this is a reliance source or not even though it is part of USDA, but it does seem correct although I am unsure how coffee is an alkalizing drink. Please tell me what you think of this database.
