The Process of Food Consumption


the Process of Food Consumption

exist at national and local levels, and may worsen unless focused efforts are made. These dietary changes are compounded by lifestyle changes that reflect reduced physical activity at work and during leisure time ( 2 ). Globally, the share of dietary energy supplied by cereals appears to have remained relatively stable over time, representing about 50 of dietary energy supply. The annual growth rate of world demand for cereals has declined from.5 per year in the 1970s and.9 per year in the 1980s to only 1 per year in the 1990s. The increase in urbanization globally is another challenge. The increase in the world average consumption would have been higher but for the declines in the transition economies that occurred in the 1990s. Any recommendation to that effect will have implications for all components in the food chain. Likewise, land and water requirements for meat production are likely to become a major concern, as the increasing demand for animal products results in more intensive livestock production systems ( 10 ).

About 20 of the worlds population derives at least one-fifth of its animal protein intake from fish, and some small island states depend almost exclusively on fish. Table 1 shows that current energy intakes range from 2681 kcal per capita per day in developing countries, to 2906 kcal per capita per day in transition countries and 3380 kcal per capita per day in industrialized countries.

Milk yields should improve, while breeding and improved management should increase average carcass weights and off-take rates. These crops will account for 45 out of every 100 extra kilocalories added to average diets in developing countries between now and 2030. In contrast, 24 countries were above the maximum recommendation of 35, the majority of these countries being in North America and Western Europe. Aquaculture compensated for this marine slowdown, doubling its share of world fish production during the 1990s. Future per capita consumption of oil crops is expected to rise more rapidly than that of cereals.



the Process of Food Consumption

Compulsive overeating, or emotional eating, is "the tendency to eat in response to negative emotions". Empirical studies have indicated that anxiety leads to decreased food consumption in people with normal weight and increased food consumption in the obese.
