FOOD CONSTITUENTS.
The Wise Combination of Food.—In order that each meal may be planned to meet the needs of the body it is necessary that it contain protein, fat, carbohydrate, mineral matter, and water. Some flavor foods should enter into each meal.
Flavor is important because it stimulates the appetite and because it stimulates the flow of digestive fluids and thus aids digestion. Such foods are only injurious when they are used to excess. In that case the nerves which control the flow of digestive fluids are overstimulated and at last become weakened. Avoid the use of too many flavors at one meal.
