hygienic-dietetic system, means supplying to the blood such chemical
elements as will replace what are missing in defective tissues of the
body.

I will now outline the methods of carrying it into effect.

In a general way there are three means of doing this:

No. 1. _Diet_: The first and most natural way is by proper diet.

As the normal chemical elements are introduced into the body as
constituents of the regular daily food, the task which, in the first
place, confronts the hygienic-dietetic physician is that of regulating
the quantity, quality and description of food.

Too little importance has heretofore been given to this question and,
beyond prohibiting certain dishes and obviously detrimental viands,
little attention was paid by the average physician to the matter of the
every-day nourishment of the patient.

The hygienic-dietetic physician on the other hand, employs the utmost
care in giving to the patient everything that will help to regenerate
his blood, laying particular stress on such foods as contain the largest
proportion of the chemical elements that are missing in the affected
tissues.

No. 2. _Nutritive compositions_: The process of destruction, however,
which has to be met, in more or less advanced stages, in nearly every
case requires supply, in quantity of the pure material to compensate the
deficiency of the missing elements, beyond that which could be derived
