But it is quite rare to read about zinc deficiency. It weakens the immune system, for instance, and indirectly contributes towards annual mortality rates of around two million for children suffering from infectious diarrhoea diseases. However, zinc is not only an important element in a healthy and strong immune system – it also contributes to the physical and neuropsychological development of children and young adults. Studies show that children with zinc deficiencies often suffer from delayed growth, arrested development, impaired sight and poor wound healing.
Zinc is a micronutrient that is present in every human cell and is most highly concentrated in muscles and bones. It plays a crucial role in the function of around 300 enzymes that are responsible for the metabolism. This micronutrient is also important for bone formation and for the interaction between brain cells. For instance, zinc activates the areas of the brain responsible for processing information for the taste and olfactory cells.
Our systems cannot form zinc independently so it has to be part of our diet. Foods such as lean meat, fish and seafood as well as milk products including cheese and special infant formulae have a high zinc content. Good plant sources of zinc include wholemeal products and wheat germ.
Around a billion people are affected by a mild to severe zinc deficiency around the world. UNICEF works on the assumption that even in the 35 richest countries in the world around 30 million children suffer from a “hidden hunger” for zinc, possibly as a result of one-dimensional or unhealthy nutrition. Unfortunately, there have been no national studies to date, although it is a highly current topic. The HOCHDORF Group is also engaging with the issue, in its current Baby Care range and in the children’s foods it is developing.
