LESSON VIII

Foods of Vegetable Origin

GRAINS

Grains constitute the most important article of human food, not so much on account of their superior nutritive, curative or remedial value, but chiefly because of their prolific growth and abundant production in all civilized countries throughout the world.

The variety of grain produced in the various countries depends largely upon the climate and the habits of the people.

The predominant use of rice by the Asiatics, wheat by the Europeans, and maize by the aboriginal American, shows how people adapt themselves to the foods of prodigal growth. It also shows the effect different foods have upon the physical development of the various tribes that inhabit these remote countries.

Wheat is said by some writers to be a complete food. This is not strictly true. Wheat contains a very small percentage of fat, and while fat can be made in the body from carbohydrates, it is more natural, and entails less work upon the digestive organs and the liver if the diet is balanced so as to contain the required amount of fat, and all other nutritive elements in the right or natural proportions.

A diet composed of wheat alone would contain 70 per cent of carbohydrates, chiefly in the form of starch. While this would be perfectly wholesome, it would give the body an excess of starch which would ultimately result in intestinal congestion, gout, rheumatism, hardening of the arteries, and premature old age. Wheat contains a larger quantity, and a greater variety of proteids than any other grain, but wheat proteids are more difficult to digest than the proteids of milk, eggs, or nuts.

Wheat varies greatly in composition, according to the soil and the climate in which it is produced. This fact is not
