Seeds—cereals, legumes, some nuts (peanuts, chestnuts).
6. Fat:
Milk (cream), egg-yolk, meat or fish (fat), fruit, as the olive (oil), most nuts (walnut, butternut, pecan, peanut, etc.).
Besides the necessary substances in food, the pupils must be told that there are other points for the housekeeper to consider when preparing the meals, namely:
1. The amount of each food substance required daily.
2. Special requirements of individuals according to: (1) age, (2) occupation, (3) climate, (4) season.
Under 1, above, it may be explained, that when a meal is prepared which gives the body a correct proportion of each food substance, it is said to be well balanced. From numerous experiments the "Dietary Standard" for one day for a grown person has been calculated to be:
Water—about 5 pints, two of which are taken in solid food
Mineral matter—1 ounce
Protein—3 to 4-1/2 ounces
Fat—2 ounces
Sugar and starch (together)—14 to 18 ounces.
Although the pupils cannot be expected to follow this table accurately, from lack of sufficient knowledge, it will be of some assistance to them in choosing a combination of food for the home meals.
