Medical evaluation of the special supplemental food program for women, infants, and children.

The special supplemental food program for women, infants, and children administered by the United States Department of Agriculture, was evaluated nationally. Participating infants, children under 4 years old, and pregnant and nursing women were investigated initially, and after receiving food supplements. The supplements were iron-fortified infant formula, iron-fortified infant cereals, and fruit juices for the infants, and milk, cheese, iron-fortified cereals, eggs, and fruit juices for the children and women.

Diet-hormone interrelationships in the rat.

Twenty-eight-day old male rats were fed, either ad libitum or in restricted amounts, isoenergetic diets containing 2, 5, 10, 15, 25, or 50% lactalbumin and 5, 11.9, or 21.1% fat for 8 weeks.

Influence of diet on growth in the rat.

Twenty-eight-day old male Sprague Dawley rats were fed, either ad libitum or in restricted amounts, isoenergetic diets containing 2%, 5%, 10%, 15%, 25%, or 50% lactalbumin protein and 5%, 11.9%, or 21.1% fat for 8 weeks and were then killed.

Effects od dietary protein, fat and energy on blood hemoglobin and hematocrit in the rat.

Twenty-eight-day old male Sprague-Dawley rats were fed diets containing varying levels of protein, fat and energy for 8 weeks and were killed. Blood hemoglobin and hematocrit measured at the time of killing increased progressively with increases in the level of dietary protein up to 50% protein. The Mean Corpuscular Hemoglobin Concentration (MCHC; hemoglobin concentration in g/100 ml red blood corpuscles) reached a plateau in rats fed diets containing 15% protein or more.

Experimental protein and energy in the rat.

Young male rats (100-130 g) were fed diets of equal energy content containing o.5, 1,2,3,5, and 18% lactalbumin consumed either freely or in restricted amounts. The rats receiving low protein diets failed to grow and mature.

The development of the serum protein pattern in Africans.

The serum protein of African and European mothers, African and European umbilical cord blood, and African children up to 6(1/2) years of age have been investigated. African umbilical cord blood contains significantly higher concentrations of gamma globulin than European umbilical cord blood. Significant differences were not found in the other protein fractions.
