For the estimation of demand, the suitable index for Jamaica has been considered to be
the per capital national income. For the other territories (Trinidad and Tobago; the Lee-
ward Islands, Windward Islands and Barbados; and British Guiana) the index used was per
capital consumption expenditure. Although consumption expenditure is supposed to have a
constant relationship with the growth of national income in general, we have considered
this relation not to be true for these three territories because of the unbalanced structure
of their economies.

 The details of food consumed per capital and its calorie contents are shown for each of
the territories in Tables 7a to 7d. Protein and fat consumption is shown in Table 8 for
Jamaica only. Summary Table 3. 5. ii, showing the per capital consumption per day of cal-
orie, protein and fat, by food groups, will be useful for comparison of food consumption
in the various territories. The calorie content of food in 1958 was highest in Trinidad and
Tobago, and British Guiana. Although Jamaica had a higher per capital income in 1958 than
British Guiana, the calorie content of Jamaican food consumption was lower than that of
British Guiana. This is presumably because expenditures on food have not been much dif-
ferent in both territories in spite of large differences in income, and furthermore, the in-
come distribution in Jamaica may be considered as having a significantly higher range than
in British Guiana. However, as a result of future economic growth in the other territories,
by 1957 British Guiana will have the lowest calorie consumption. Thus, it is estimated
that the calories will increase from 2,111 in 1958 to 2,635 by 1975 in Jamaica, 2,533 to
3,024 in Trinidad and Tobago, 2,040 to 2,455 in the Leeward Islands, the Windward Islands
and Barbados, and 2,200 to 2.254 in British Guiana.

 Protein and fat contents of food have been estimated for Jamaica only. It is estimated
that the consumption of protein per day will go up from about 56 grams in 1958 to about 70
grams by 1975, and the consumption of about 34 grams of fat in 1958 will increase to about
47 grams by 1975. The protein and fat consumption in other territories will also be about
the same since major sources of protein by food groups are starchy foods, meat and fish,
and those of fat are starchy foods, meat, fish, milk and oils, etc. Fruits are also an im-
portant source for protein and fat, but the consumption of fruits differs widely among the
territories. However, the presence of more starchy foods and oils and fats in the food
consumption of other territories will offset the lower consumption of fruits, sugar and
eggs, and thus protein and fat consumption will be comparable with that of Jamaica.

 Thus, the nutritional value of food consumption in these territories does compare fa-
 vourably with other countries having similar income and climatic conditions, etc. It may
 also be noted that the above analysis is based on main food items only, and estimates of
 tea, coffee, cocoa, and alcoholic and non-alcoholic beverages could not be considered in
 our study. The inclusion of these items will increase the calorie content to some extent
 and present a more favourable picture.
