Cheese is a very nutritious food, containing twice as much nitrogen as meat, and three times as much fat. However, it is difficult to digest, although rich cheese is easier of digestion than skim milk cheese. For persons who take plenty of outdoor exercise especially, cheese is a valuable article of diet.

Eggs are a perfect natural food and form a good substitute for meat. When properly cooked, they are easily digested, although a "hard-boiled" egg requires about three times as long to digest as a raw one. They are deficient in the carbohydrates, but the latter may be supplied by the use of bread, sugar, etc., in connection with them. So, we see that eggs make an ideal breakfast dish, since they nourish without overtaxing the stomach at this first meal of the day. Far too often, in America especially, breakfast is made an elaborate, hearty meal, clogging and overworking the system. It should consist, instead, of light and easily digested foods, such as fruit, cereals, eggs, whole wheat breads, etc., with little or no meat. However, variety we must have, and the menu for breakfast should be studied as carefully as for any other meal in the day. In winter, it may be slightly heavier than in summer, when fruits, cereals and bread, with perhaps a suitable beverage, would be enough.
