Zinc is one of the most important essential trace metals.
1. Brain
The blood zinc level is less in patients with Alzheimer’s and Parkinson’s disease (Brewer, and others 2010). In a rodent study, it was observed that zinc behaves like an antidepressant (Nowak and others, 2005).
2. Cardiovascular System
Zinc performs a noteworthy role in the regulation of arterial blood pressure. Males and females were reported to metabolize zinc differently when suffering from hypertension (Tubek, 2007).
3. Liver
Zinc deficiency in the liver occurs not only in those with liver cirrhosis, but also in less advanced alcoholic and nonalcoholic liver disease (Bode and others, 1998).
4. Pregnancy
A mild deficiency of zinc during a pregnancy can cause increased maternal morbidity, abnormal taste sensation, prolonged gestation, inefficient labor, atonic bleeding, and an increased risk to fetuses (Jameson, 1993).
5. Diabetes
Zinc is very important in the synthesis, storage, and secretion of insulin (Chausmer 1998). A low level of zinc has been shown to play a role in diabetics with associated disease conditions such as coronary artery disease and several related risk factors including hypertension, and elevated levels of triglycerides (Singh and others, 1998).
7. Healing
Zinc deficiency has been linked with delayed wound healing, and has been found to be crucial to the healing of gastric ulcers especially at the early stage (Kennan and Morris, 1993; Andrews and Gallagher-Allred, 1999; Watanabe, 1995).
8. Pneumonia
Zinc may shorten the duration of severe pneumonia and time in the hospital (Brooks, 2004).
