A Small Increase in Zinc Intake Protects DNA

By jeremyc | January 6, 2017

Zinc is regarded as one of the most important mineral—and for good reasons. It is essential for a healthy immune system, as well as for growth and development. A new study reveals that increasing the daily intake of zinc by even a small amount helps in DNA protection.

Vital for promoting healthy growth during childhood as well as adolescence, Zinc is an essential trace element which helps stimulate activity of no fewer than hundred different enzymes. It also plays an important role protein and DNA synthesis, as well as healing of wounds. Zinc also offers protection against certain types of cancer and cardiovascular disease, thanks to its ability to limit oxidative stress and inflammation.

With ageing, DNA deteriorates. However, the human body can regenerate DNA until old age. With that said, the ability of the body to repair wear and tear of DNA becomes less if the intake of zinc is low. According to the National Institutes of Health, the recommended daily intake of zinc for men and women is 11mg and 8mg, respectively.

Foods rich in zinc include, among others, the following: spinach, beef, kidney beans, shrimp, flax seeds, oysters, watermelon seeds, pumpkin seeds, garlic, peanuts, lima beans, egg yolks, pork, dark chocolate, turkey, cashews, salmon, chickpeas, and lobsters.
