Hello All!!!!

Food combining is scientifically called ‘Trophology’. It is the science of knowing which foods can be combined with which other foods. Food combining can also mean the combination of foods that are compatible to each other with respect to their digestive chemistry. When we talk about optimal nutrition, food combining is the basic component as it allows the body to digest the food and utilize its nutrients to the full extent.

Food combining has its roots in the theory that different food groups have different digestion times. Digestion can be helped a lot when you consume foods with about the same digestion time. This means that for proper digestion, utilization and assimilation of foods you need correct food combinations.

Digestive chemistry is known to dictate the principles of food combining. Different foods need different digestive enzymes in order to aid the process of digestion. Some are acidic whereas some are alkaline.
