Nutritional status of high school girls at Jeddah, Saudi Arabia

The nutritional status of girls of the High School in Jeddah, Saudi Arabia was studied. Mean body weights and heights for age of girls show that all girls were less than the standard except for the age group 19 for body weight. About one third [34%] of the girls were under weight or lean. The caloric intake and protein consumption were higher than the recommended dietary allowances [RDA]. The girls got only 40% of the RDA of vitamin A, and 57% of vitamin C. One fourth [24%] of the girls are accustomed to eat no breakfast

Effect of processing on corn and parboiled rice proteins

The nutritional quality of corn and parboiled rice before and after processing was estimated. Data for food intake, weight gain and food efficiency of corn and rice revealed that baking of corn had a significant effect on its nutritive value. On the other hand cooking of rice did not affect its nutritive value significantly. However, when the relative nutritive value [RNV] was estimated by the slope ratio bioassay, there was decrease in the RNV after baking corn or cooking rice. This decrease was found on the basis of either the body weight gain or moisture gain in the bodies of the rats as response parameters
