Abstract
The present work aimed to study the zinc content of human and cow milk as well as some plant products which are used for preparing some natural foods and juices for feeding infant as food supplement. Also, the present study calculated the dietary zinc intake to ensure normal growth and good health for infants. Ten lactating mothers supplied monthly samples of human milk allover the year (2003). Milk samples from cows were taken from 5 governorates allover the same year. Samples of eggs, vegetables (potatoes and green peas), fruits (apple, banana and orange), cereals (wheat and rice) and legumes (lentil) were collected from the same 5 governorates. Skim milk was prepared from cows. Belila, boiled rice, lentil, potatoes, green peas and eggs were prepared. Orange juice was prepared. Zinc concentration was determined in all the above mentioned products.
Results showed that zinc concentration in human milk ranged from 0.63 to 3.8 I-1g 1 ml, while, cow's milk contained the lowest zinc concentration ranged from 0.007 to 0.017 I-1g 1 ml. on the contrary, zinc concentration was relatively high in whole boiled eggs ranged from 1 to 1.5 mg. Zinc concentration was 5 mg/100g in lentil, 3 mg 1100 gm in belila, ,0.4 mg 1100 g in boiled rice, 4 mg 1100g in green peas, 0.3 mg 1100g in potatoes and 0.2 mg 1100g in banana. Orange juice has the lowest recorded value of 0.02 mg 1100 g.
Since the recommended dietary allowances set by the Food and Nutrition Board (1980) was 3-5 mg 1 day of zinc as intake for infants during the first year of age, five regimes were suggested. The calculation of these regimes based on the age of infants and the requirements of k call day and protein ( gl day) and calculation of zinc concentration of each regime to supply the infants with the satisfied nutrients and recommended zinc concentration.
