Zinc

NEWS:

No proof zinc lozenges help cold symptoms "There's no proof that zinc lozenges, which are marketed for relieving symptoms of the common cold, work as advertised, according to a new research review. Zinc nasal gels, on the other hand, show some promise for aiding stuffy, runny noses, researchers found. "

Too Much Zinc Linked to Blinding Eye Disease "Zinc may be behind the development of a potentially blinding eye disease. Large amounts of the mineral zinc were present in patients with age-related macular degeneration (AMD), prompting researchers to suggest a link between the mineral and the disease. AMD is the primary cause of blindness in the elderly in Western society, and approximately 13 million Americans suffer from the disease. Zinc supplements are widely given to patients to help boost weak immune systems, so study authors fear these findings may show the supplements are doing more harm than good. "

JOURNAL ARTICLES:

Effect of Zinc Supplementation on Thyroid Hormone Function (Annals of Nutrition and Metabolism 2007) "Conclusion: Zinc supplementation appeared to be directly responsible for the increase in plasma zinc and decline in serum ferritin concentrations in both subjects. Zinc supplementation appeared to have a favorable effect on thyroid hormone levels, particularly total T3, and RMR."

Effects of zinc supplementation on antioxidant enzyme activities in healthy old subjects. (Exp Gerontol. 2007) “These data suggest the potential beneficial effects of Zn supplementation on Zn-dependent antioxidant enzymes in healthy elderly subjects.”

High dose zinc increases hospital admissions due to genitourinary complications. (J Urol. 2007) "CONCLUSIONS: Zinc supplementation at high levels results in increased hospitalizations for urinary complications compared to placebo. These data support the hypothesis that high dose zinc supplementation has a negative effect on select aspects of urinary physiology."

Zinc and ageing: third ZincAge conference. (Immun Ageing. 2007) "During ageing, the intake of Zn decreases due to inadequate diet and/or intestinal malabsorption, contributing to frailty, general disability and increased incidence of age-related degenerative diseases (cancer, infections and atherosclerosis). Although many factors contributing to Zn deficiency,have been identified, the biochemical markers of Zn deficiency as well as the possibility to achieve relevant health benefits trough Zn supplementation in the elderly are still a matter for evaluation. Taking into account that Zn homeostasis is regulated by proteins and enzymes for which polymorphisms have been previously found to be associated with successful/unsuccessful ageing, genetic screening might be of added value in evaluating the individual response to Zn supplementation."

Zinc and inflammatory/immune response in aging. (Ann N Y Acad Sci. 2007) "A large number of studies have documented changes in zinc metabolism in experimental animal models of acute and chronic inflammation and in human chronic inflammatory conditions. In particular, modification of zinc plasma concentration, as well as intracellular disturbance of antioxidant intracellular pathways, has been found in aging and in some age-related diseases. Zinc deficiency is diffused in aged individuals in order to avoid meat and other high zinc content foods due to fear of cholesterol."
