ry studies show that as personal income increases, so does the average number
of calories consumed. The proportion of overall calories contributed by animal
protein, animal fat and sugar is also relatively high for people with higher in-
comes.
    In contrast, with lower levels of personal income, fewer calories are consumed
and the proportion of those calories from animal protein is very low. Most of cal-
ories in the diets of people in low income regions come from carbohydrates, pri-
marily from grains, which may not supply all of the essential amino acids. Amino
acids are the building blocks of proteins. The amino acid composition of fish flesh
is very close to our dietary requirements. Fishes and shellfishes provide the type
of food that people in both rich and poor nations need-relatively low in fat and
high in protein. The protein content of fish flesh is 19% (of wet weight) which is
relatively high, while the caloric content is relatively low. Among the fats found
in seafood are some special ones that are thought to be particularly beneficial to
human health.
    An epidemiological study comparing the health of Eskimos, who have diets
rich in seafood, with Danes, whose diets are high in chicken eggs, milk products
and red meat showed that the Eskimos had significantly fewer instances of coro-
nary heart disease, psoriasis and bronchial asthma than Danes. Since that study,
the kinds of fats and oils present in fishes and shellfishes have received consider-
able research attention regarding their potential health benefits.
