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.
