Finally, you can eat heartily – chocolate and coffee help you to live longer. As a new study, published in the journal Nature Chemistry, now shows, these foods can slow down the aging process. However, only if it is combined correctly – with zinc. The right mix of enjoyment and zinc protects against aging scientists from the University of Erlangen-Nuremberg and Auburn University in Alabama have discovered that the interaction of coffee, tea or chocolate with zinc supplements activates a compound which can slow down the aging process. The combination can therefore provide for a longer life, as it protects against "oxidative stress". This creates harmful gases as a by-product of the cell. And that not only leads to fine lines, but can also cause other diseases, such as cancer, inflammation or degenerative diseases. To investigate the effects of zinc and antioxidant polyphenols that can be found in coffee, chocolate and tea, the researchers combined both things together. Although polyphenols can not break down oxidative stress alone, in combination with zinc, they form a so-called "mega-complex" that can protect the body from harmful exhaust fumes. "It is quite possible that wine, coffee, tea or chocolate in may be available with added zinc in the future. "According to the study, unlike other metals, zinc is more effective because it is less toxic. This led scientists to hypothesize that zinc could be added to foods in the future to "increase consumer health". The main author of the study, Prof. dr. Ivana Ivanović-Burmazović said in the survey, "It is quite possible that wine, coffee, tea or chocolate may be available with added zinc in the future." The Benefits of Chocolate Earlier research has shown that consuming chocolate is a common practice Can have advantages. The sweet snack can not only improve memory, reduce stress and also make you very happy – now there is also anti-aging on the pro chocolate list.
