Chapter XIII

The food on which the man who would be healthy should live should be selected so as to ensure variety without excess. Animal food should not be taken oftener than twice daily. The amount of animal and vegetable food combined should not exceed thirty ounces in the twenty-four hours, and for the majority of persons an average of twenty-four ounces of mixed solid food, a third only of which should be animal, is sufficient. All animal foods should be eaten while they are fresh and after they are well cooked. The habit of eating underdone flesh is an almost certain cause of parasitic disease. The amount of fluid taken, in any form, should not exceed an average of twenty-four ounces daily. Water is the only natural beverage.
