Zinc Deficiency and Old Age.

Zinc deficiency may develop with age, leading to low-grade chronic inflammation that has been associated with cancer, heart disease, and diabetes. Low zinc levels have also been associated with a weakened immune system response. In animal studies, older subjects showed signs of zinc deficiency even through their diets should have provided adequate amounts of the nutrient. The researchers believe the aging process alters the body’s ability to efficiently transport zinc to our cells. When the test animals were given more than the recommended daily amount of zinc, biomarkers related to chronic inflammation returned to levels seen in younger subjects.
