Nature supplies food; men and women cultivate it; women and men prepare it; humanity needs it and eats it. Human life continues through food nourishment; work is done by food-energy. Strength and health depend upon the food eaten, its kind, combination, quantity, quality.

Eating is a common physical necessity of all living things.

Doing and learning are both needed to produce, choose, prepare the foods human beings require for life, health, strength, growth, work.

Skill and specific scientific knowledge are required for the best production of food to-day. Individual producers therefore no longer attempt to grow everything, but simply what can be well and economically grown together. Only what cannot be thus grown in a locality needs to be brought from afar. It is thus that humanity is healthfully nourished and so occupied as to develop both physically and mentally.

Knowledge and experience concerning wholesomeness in food is a general necessity, especially as factory industry commercially supplies humanity with much of its food. Ability to select nutritious food continues an urgent need even when food is prepared outside of the home.

Humanity is increasingly studying its food-needs and how to meet these more adequately, yet less laboriously.

Food serves a human purpose only as it nourishes humanity.

Science studies what is happening to find how living may be made so to interwork with nature as to make life stronger, more wholesome, and human well-being the natural state of humanity.

Food-Science is a study of Hitman Foods and Human Nutrition (that is, the way the body uses food), to learn how to promote Hitman Nourishment, hence Human Health, through such Food Habits as establish Digestion-Efficiency.
