Whats the fastest way to digest food ?
Chew it well
However fast your digestive system allows for.
Use pro-biotics, either from the chemist and health store. Eat small amounts at a time. Check for food intolorances.
Thorough mastication. Chew it till it is almost a semi liquid (if solid)
Drink plenty of liquids.
Put it in a blender and drink it. There's less time for the food to break up in the stomach if it's already broken down.
