Eggs, certain cheeses, meats and butter can raise the body's acid level.
Consequently, margarine is alkaline-promoting as is olive oil and even butter is used judiciously. Dr. Oz recommends a 2:1 ration when pairing alkaline with acid-promoting foods, or two servings of alkaline-promoting foods for every single serve of acid-promoting foods.
