Clay
We all know the beauty benefits of clay since it is such a huge part of the beauty industry in general. There are, however, parts of the world where people eat clay as part of their diet on a regular basis -especially the Middle East and Africa. It’s also taken as a supplement by people who are zinc deficient. In addition to that, it supports healthy digestion by removing toxins from the gut. Keep in mind that in order to consume clay, it should be of food-grade quality.
