It will help to give a picture of food values if, before going further,
we note how much it takes of some of the common foods to make a given
amount of food value, say 100 calories. It is surprising in how many
cases the ordinary amount of food served at table happens to contain
about 100 calories. We find 100 calories in a small lamb chop (weighing
about an ounce); in a large egg (about 2 ounces); in a small side-dish
of baked beans (about 3 ounces); in 11/2 cubic inches of cheese (about an
ounce); in an ordinary side-dish of sweet corn (about 31/2 ounces); in one
large-sized potato (if baked, about 3 ounces; if boiled, about
4 ounces); in an ordinary thick slice of bread (about 11/2 ounces); in one
shredded wheat biscuit (about an ounce); in a very large dish of oatmeal
(about 6 ounces); in a small piece of sponge-cake (about an ounce); in a
third of an ordinary piece of pie (about 11/2 ounces); in three
teaspoonfuls or 11/2 lumps of sugar (about 1 ounce); in a dozen peanuts
(about 1/3 of an ounce); in eight pecans (about 1/2 an ounce); in four
prunes (about 1 ounce); in two apples (about 7 ounces); in a large
banana (about 4 ounces) in half a cantaloup (about 9 ounces); in seven
olives (about 11/2 ounces); in a very large orange (about 10 ounces); in
an ordinary pat of butter (about 1/2 an ounce); in a quarter of a glass of
cream (about 2 ounces); in a small glass of milk (about 5 ounces). (See
