_Key to Key_

[Sidenote: _Remember This_]

If you will remember the following portions of food, you will have a
standard by which to compute your servings:

Lean Meat: a piece 3 x 2 x 1/2 (2 oz.) 100 C.
Now if your serving of meat or fish is fat,
mentally cut in two for same value. If very
lean, you should add a little.
White Bread: slice 3 x 4x 1/2 100 C.
Compute other breads by this.
Butter: 1 scant tablespoonful 100 C.
Sugar: 1 heaping teaspoonful 50 C.
Potatoes: 1 medium, boiled or baked. 100 C.
Watery Vegetables: 1 helping 15-35 C.

If food is fried, or butter, oil, or cream sauces are added, the C.
value increases markedly.
