Coffee tea and chocolate plus zinc slows aging processes gesundheitsstadt berlin

Aging processes are caused, among other things, by oxidative stress. Researchers from Germany and the U.S. have discovered a new protective mechanism: consuming zinc along with foods such as coffee, tea and chocolate slows down the aging process.

Zinc is one of the trace elements we need to stay healthy. Zinc now forms an organic molecule with a certain component from these foods. This component is a hydroquinone group found in polyphenols, the plant compounds responsible for smell and taste. Zinc activates the hydroquinone group. Thus forms a natural protection against superoxide. Superoxide is an intermediate product of human cellular respiration that damages the body's own biomolecules, for example proteins or fats, as well as genetic material. It is therefore associated with the aging process and a variety of diseases such as inflammation, cancer or neurodegenerative diseases.

Hydroquinone alone is not able to break down superoxide. However, when zinc and hydroquinone combine, a metal complex is formed that mimics a superoxide dismutase (SOD) enzyme. Such an enzyme protects the body from the decomposition processes caused by oxidation. Consequently, it has an antioxidant effect.

Harmful superoxide is metabolized

In this way, the superoxide can be metabolized and damage to the organism can be prevented, conclude the researchers led by Prof. Ivana Ivanovic-Burmazovic of the Friedrich Alexander University of Erlangen-Nuremberg and Prof. Christian Goldsmith of Auburn University in Alabama. The results of their study were published in the journal Nature Chemistry.

What is special about these results is that the function of this enzyme is replicated without the use of redox-active transition metals such as manganese, iron, copper or nickel, a press release further states. The metals could also have an antioxidant effect, but this effect is quickly reversed: when overdosed, they actually promote oxidative stress. Zinc is far less toxic than the transition metals mentioned above, allowing for new drugs or supplements with fewer side effects.

Food supplements can lead to overdoses of vitamins or minerals and thus cause undesirable side effects. The Federal Institute of. READ

Coffee, tea and chocolate plus zinc slows aging

On the one hand, coffee, tea and chocolate in combination with zinc slow down the aging process. It is also conceivable, however, that foods naturally containing hydroquinone could be enriched with zinc to promote consumer health. "It is quite possible that at some point there will be zinc-infused coffee, tea or chocolate.", Ivana Ivanovic-Burmazovic emphasizes.
