Different food categories require different combinations of digestive juices for proper digestion. Proper food combining means eating those foods together that require the same chemical environment for their digestion. Proteins need a very acidic environment. Starchy foods, such as grains in any form (bread, pasta, rice, etc.) and potatoes, are digested in a more alkaline environment. If you eat both a starch and a protein at the same time, expect problems.
