Silicon is a rather neglected element when it comes to a balanced diet. The semi-metal is advertised primarily as a dietary supplement that is said to be good for hair and bones. We say what’s in it from a scientific point of view.
Is silicon important for humans?
Silicon is a non-essential trace element: it does not have to be supplied to the body through food. About 20 milligrams of silicon per kilogram of body weight are naturally stored in our connective tissue, skin, tooth enamel, and bones. For this reason alone, dietary supplements containing silicon are advertised as beauty products that strengthen connective tissue and ensure full hair and firm skin. This is by no means scientifically proven. The consumer center even warns against taking the trace element, which is offered in a bound form in preparations with silicic acid or as organic silicon. Because silica & Co. could be contaminated with toxic lead or contain minerals in a very high concentration. That would put unnecessary strain on the kidneys. For pregnant women, the recommendation is not to take silica under any circumstances.
Silicon is found in many foods
Anyone who eats a balanced diet usually eats enough foods that naturally contain silicon anyway. Millet, potatoes, spinach, peas, peppers, pears, grapes, strawberries, and bananas are among the possible sources of trace element. In addition, silicon is often a component of water. Supplied in this way, we consume up to 25 milligrams of silicon daily and need not worry about whether our diet is sufficient for healthy hair. Only when there are very few vegetables and fruit on the menu and instead of many animal products do we take in little silicon. Because meat, sausage or milk are free of it.
Balanced nutrition instead of capsules and powder
Whether we can completely do without silicon is still unclear and is the subject of research. Some studies claim to have found a connection between the intake of the trace element and bone density. However, since the data situation is still insufficient, no recommendations can be derived from it. Our tip: simply eat colorfully! If fruit and vegetables of all colors and grain products regularly end up on the plate, you are not only supplying the body with sufficient amounts of silicon, but also many other important nutrients. You can confidently do without the expensive powders and capsules!
