Systematic review of zinc biochemical indicators and risk of coronary heart disease
<div><p><strong>BACKGROUND:</strong> Poor zinc nutritional status is suspected as a risk factor for coronary heart disease (CHD). Since zinc absorption may be influenced by some nutritional and physiologic factors, it would be better to investigate zinc status through biochem...
