What does food supply us with?
Answers
Answer:
food supply us Nutrition and energy
Answer:
lists the daily per capita intake of nutrients during certain years between 1909 and 1976. These estimates, based on food disappearance data reported by Page and Friend (1978), show that if nutrients alone are measured, the food supply appears to have undergone little overall change during this period. There has been a slight decline in total calories available for consumption, essentially no change in total protein, and a moderate increase in total fat, balancing a similar decline in total carbohydrate. The available supply of most of the vitamins and minerals measured has remained essentially unchanged. The exceptions are iron and vitamins B1, B 2, and niacin, which have increased, and magnesium, which has decreased. The increases probably reflect the enrichment of a variety of flour-based products. Since magnesium is lost during the refining of flour, as are a number of trace minerals, the decline in magnesium intake might reflect a general decline in trace minerals, especially those derived from whole grains. If one were relating U.S. trends in per capita intake to trends in cancer incidence, these data suggest that the relatively stable nutrient composition of the diet is being reflected in the relatively stable cancer rates at most sites.
