    contract is the carbonaceous food which gets burnt up in them. 44. An infant which lies in its cradle asleep nearly all day does not exercise its muscles much. All the time, however, it is growing rapidly and its muscles are increasing in size. A young baby, therefore, requires much more building material but less fuel, in propor- tion, than an adult. In other words, a baby requires a larger proportion of nitrogenous and mineral food, but a smaller proportion of sugar. This is exactly what is found in a baby’s natural food—namely, milk. 45. Older children, whose muscles are constantly growing and who are always exercising their muscles by running about, require a large supply both of nitrogenous building material and of carbonaceous fuel. The former is best supplied in milk, chicken, fish, eggs, porridge, and underdone meat; the latter in jam, honey, sugar, cream, and fat. A child brought up on tea and bread and jam alone will never have healthy muscles. 46. In adults the muscles are no longer growing much, so that only a little building material is required to repair the waste of the muscle substance. On the other hand, anyone doing hard work requires much fuel or carbonaceous food, such as bread, sugar, potatoes, and fat. Much more of these fuel foods will be required when hard work is being done than when we are not working hard. 47. Exercise is necessary for all healthy people, young and old. As people get old they tend to take less exercise, but it is just then that exercise is so
