The effect of increasing dietary zinc on the activity of superoxide dismutase and zinc concentration in erythrocytes of healthy female subjects
Article Abstract:
The effect of dietary zinc intake was evaluated in female subjects by testing the bioavailability of the mineral in a subfraction of erythrocytes. Results indicated that zinc supplementation resulted to a decrease in activity of erythrocyte superoxide dismutase. Since the enzyme's activity is also reflective of copper status, a low level would indicate an adverse effect on copper metabolism. The safety of zinc supplementation is thus being questioned in terms of the balance between its helpful and adverse effects.

Effect of zinc on lean tissue synthesis during recovery from malnutrition
Article Abstract:
Eleven severely wasted boys were given basal and zinc-supplemented diets to investigate whether the addition of zinc to basal therapeutic diets increases the retention of lean tissue and enhance protein metabolism. Results show that net intestinal absorption of nitrogen is increased by zinc-supplementation of high-energy soya based diets given to malnourished children. In addition, measurements from ammonia enrichments suggest that additional zinc increases nitrogen retention and protein metabolism.

Effects of short-term zinc supplementation on cellular immunity, respiratory symptoms, and growth of malnourished Ecuadorian children
Article Abstract:
A randomized double-blind placebo-controlled study reveals the favorable impact of zinc supplementation on immunity to respiratory infections in malnourished Ecuadorian children. Better delayed-type hypersensitivity reaction, and higher levels of serum zinc accompany the supplementation. Symptomatic variations in some respiratory tract infections necessitate community-based studies on larger population groups.
