Aging and low life expectancy have been formed, at least partly, by oxidative stress, researchers at the Erlangen-Nuremberg University in Germany said.
The study, published in the Nature Chemistri magazine, found that zinc can activate an organic molecule that helps protect against oxidative stress.
"It is certain that wine, coffee, tea or chocolate will be available in the future with additional zinc," said Ivan Ivanovi-Burmazov of the Erlangen-Nurnberg University.
"However, any alcohol content would destroy the positive effects of this combination," said Ivanovi-Burmazovi.
Zinc is needed by traceable people to stay healthy.
Researchers, including those from the University of Auburn in the United States, have found that zinc can protect the superoxides responsible for oxidative stress when taken together with a component found in food products such as wine, coffee, tea and chocolate.
This component is the hydroquinone group found in polyphenols – the plant responsible for the smell and taste, researchers said.
Zinc activates hydroquinone groups, creating a natural protection against superoxide, a byproduct of human cellular respiration that damages one's own biomolecules of the body, for example, proteins or lipids, as well as the human genome.
Supercocides are considered to have a role in the aging process and a range of diseases such as inflammation, cancer or neurodegenerative diseases.
Only hydroquinone is not capable of crashing the super-cake.
However, if zinc and hydroquinone are combined, a metal complex that imitates superoxide dismutase enzyme (SOD) is formed.
These enzymes protect the body from the degradation process caused by oxidation and have an antioxidant effect.
In this way, the superoxide can be metabolized and prevent damage to the organism; oxidative stress is avoided.
For the first time, the function of this enzyme is copied without returning to redox-active transitional metals such as manganese, iron, copper or nickel.
Although metals can also have an antioxidant effect, any positive effect is quickly outweighed by the fact that if it is taken too much, it can increase oxidative stress.
Zinc is much less toxic than transition metals, which allows the creation of new drugs or additives with significantly less adverse effects, researchers said.
It would also be probable that zinc is added to foods containing hydroquinone, of course, in order to improve health, they said.
