ty.

3. Utilization of food by the body necessitates:

(a) Transformation through a series of processes:

(1) Digestion.

(2) Absorption.

(3) Metabolism.

(4) Elimination.

(b) Factors influencing use of food:

(1) Stimulation of secretory cells through appetite
juice (stomach); hormone secretin
(intestines).

(2) Factors retarding use of food:--Fear,
worry, anger, nervous excitement, fatty
foods and alkaline carbonates (bacterial action
causing fermentation and putrefaction).

PROBLEMS

(a) Outline the processes through which a slice of bread and butter
must pass, from the time it is eaten until it reaches the blood
stream.

(b) Outline with a diagram the manner in which the foodstuffs are
utilized in the body.

(c) Show in the form of a table the effect of the enzymes on proteins,
on fats, on carbohydrates.

PREGNANCY AND LACTATION

There are many traditions in regard to the food requirements of the
prospective mother. Many of these have been proved fallacies. As a
