Zinc supplementation may protect against heart disease

With zinc supplementation being so important for a healthy heart, how can you be sure you are getting enough of it? Read below..........

To give you an idea just how important it is, zinc helps in the production of about 100 enzymes in your body, builds a healthy immune system, maintains senses of smell and taste and is needed for DNA synthesis.

In a recent study, zinc supplementation demonstrated a protective effect on the heart by functioning as an anti-inflammatory and antioxidant.

Blood CellsChronic inflammation and oxidative stress are important risk factors for heart disease. Zinc is an essential mineral with both anti-inflammatory and antioxidant functions. Because of these properties, zinc may play a role in protecting the heart.

To examine the effect of zinc on markers of inflammation, researchers conducted a randomized, double-blind, placebo-controlled trial of zinc supplementation in elderly subjects. Forty healthy elderly subjects (aged 56-83 years) were randomly assigned to 2 groups. One group received placebo; the other received 45 mg of zinc per day for 6 months.

Compared to the placebo, six months of zinc supplementation increased plasma zinc concentrations and decreased several markers associated with inflammation. Higher zinc levels were also related to a decrease in markers associated with oxidative stress.

The findings of this research suggest that zinc may have a protective effect in coronary artery disease thanks to its anti-inflammatory and antioxidant properties.

So how do you get enough zinc every day?

Note from Deanna: The Usana Multi Minerals contain 40 mgs of zinc in a daily recommended dose.

My reading suggests that the best food sources of zinc include beef, lamb, pork, crabmeat, turkey, chicken, lobster, clams and salmon.

For vegetarians, consider milk and cheese, yeast, peanuts, beans, and wholegrain cereals, brown rice, whole wheat bread, potato and yogurt. Pumpkin seeds offer one of the most concentrated non-meat food sources of zinc.

The downside of taking these high zinc foods is that no matter how much of them you take in, apparently only a mere 15%-40% of the zinc actually gets absorbed by your body overall.

Interesting that it has been found that increasing intake of vitamins such as Vitamin C, E and B6 and minerals such as magnesium can increase zinc absorption in the body.

Bottom line: Take your Usana Essentials every day (which includes the multi minerals). Be good to yourself!
