Cocoa and Chocolate are prepared from the chocolate bean. Cocoa is from the shell of the bean and chocolate from the kernel. As shown by Table VII, they are more nutritious than the other beverages; yet the fat in chocolate is not like the fat in other foods. It is not used as a reserve in animal tissue as are the other fats.
The active principle in cocoa and chocolate is theobromin and is similar to caffein in its stimulating effect upon the nervous system, though milder.
Lemonade
Lemonade and other fruit drinks, particularly those made from the citrous fruits, slake the thirst more quickly than most drinks.
All fruit drinks are diuretic, and, wherever the action of the kidneys is sluggish, they are especially desirable.
Carbonized Drinks
are made from bottling some drink, and, before sealing, forcing carbon dioxid into the bottle under pressure. As soon as the cork is removed the escape of the gas causes effervescence. These drinks have no advantage, other than that they slake the thirst.
