Tin and your healthNot long ago, it wasn't known for sure whether tin (Sn) is a nutrient essential to our health, or not. Nowadays, this micro-mineral is classified as essential, not only because our body has cell receptors for it, and contains minute but always present amounts, but also because it has been linked to some important body functions.
Still, tin as a nutrient is fairly obscured, and probably needs more attention with respect to the specifics of its food intake and the relating health effects.
Known importance of tin stems primarily from it supporting the function of adrenal gland - one of the key glands in your body. Since adrenal gland controls cardiac function, tin deficiency can result in cardiac insufficiency; also breathing difficulties, asthma, fatigue and depression.
Excessive tin intake can result in digestive problems, nausea, skin rush and headache.
There is no established DRI (Dietary Reference Intakes, the most recent set of dietary recommendations set by the government) for tin, and data about its general intake and deficiency/excess patterns are scarce and inconclusive. Suggested adequate daily intake for an average healthy adult is 10mg-20mg.
Tin sources are canned foods, as well as a variety of foods of plant and animal origin.
