SOURCES OF BASIC NUTRIENTS

No natural food can be classed as strictly protein, carbohydrate, or fat. Nearly 

 every animal and nearly every plant yields some of each nutrient, but seldom in 

 proportions suitable for our needs. By using plants and animals of various kinds, we 

 can get what we need most conveniently or most economically
