An appropriate increase of
4
mg of zinc in a daily diet can reduce
DNA
chain fractures and increase levels of proteins associated with
DNA
repair, oxidative stress, and inflammation.study, published in
American Journal of Clinical Nutrition
, confirms for the first time that an appropriate increase in dietary zinc can reduce oxidative stress and
DNA
damage. Dr
Janet King
, a senior scientist at the
Benioff
Children's Hospital Auckland Research Center at the University of California, San Francisco, said: "We are very surprised to see that just a small increase in dietary zinc can have such a huge impact on the metabolism of the entire body. The results show us new strategies for measuring the health effects of zinc and add evidence that food-based interventions can improve micronutrient deficiencies worldwide. Zincis an essential component of nearly
3,000
different proteins and affects how these proteins regulate each cell in the body. Micronutrients are essential for many biological processes, such as the growth and development of the human body, neural and immune functions. Zinc is naturally found in protein-rich foods such as meat and crustaceans, where oysters have the highest levels of zinc.micronutrient deficiency is a global issue. Bio-fortified grains, such as zinc rice and zinc wheat, can be added to the diets of people with nutrient deficiencies.Details of the study The randomized, controlled study took
6
weeks to complete, with
18,
male subjects taking a daily diet containing
6
mg of zinc for the first two weeks and a
10
mg zinc-containing diet for the next four weeks.showed that the total amount of zinc absorbed increased as zinc in the diet increased, but the concentration of zinc in the plasma did not change. With the increase of dietary zinc, the fracture of the
in
blood cells decreased. At the same time, the increase in dietary zinc also increases the
of
proteins associated with
DNA repair, antioxidants, and immune function.
