4. The cereals are all grasses
that have been bred over
millennia to bear large
seeds (i.e., grain).
5. Starchy roots consumed
in large quantities include
potatoes, sweet potatoes,
yams, taro, and cassava.
6. Beans and peas are the seeds
of leguminous crops that are
able to utilize atmospheric
nitrogen via parasitic
microorganisms attached to
their roots.
7. Vegetables and fruits have similar
nutritive properties. Because 70
percent or more of their weight is
water, they provide comparatively
little energy or protein, but many
contain vitamin C and carotene.
8. One characteristic of diets of affluent
societies is their high content of
sugar. This is due in part to sugar
added at the table or as an
ingredient in candy, preserves, and
sweetened colas or other beverages
9. Meat, fish, and eggs are high in
protein, fat, and water. Meat is a
good source of thiamin, niacin,
vitamin B12, vitamin B6, iron, zinc,
phosphorus, potassium, and
magnesium. Liver is a particularly
rich source of vitamins.
10. Cow's milk is a complete
food for its young,
providing 90% of the
necessary nutrients for
humans.
11. The animal fats used by
humans are butter, suet
(beef fat), lard (pork fat),
and fish oils.
12. Despite the fact that most adults
consume one to two litres
(approximately one to two quarts) of
water each day, the majority of this
comes in the form of liquids like
coffee, tea, fruit juices, and soft
drinks.
