Cells have small strutures called lysosomes, which contain hydrolytic
enzymes that digest the proteins, carbohydrates and lipids in the cell
when the cell is injured. When foods are not cooked so that the enzymes
are destroyed, these enzymes digest the food. This is what happens when
meat is aged, for example. When you chew the live food, it begins to
self-digests before your body's enzymes continue the process. This makes
eating raw meat, for example, more efficient. And the raw food does not
have the harmful substances formed during cooking, substances the body
can't use and therefore make the body toxic when the food is overly
cooked.
