Risks and side effects of silica

Is silica safe to eat? The FDA considers silica in food generally safe for human consumption in small amounts. Is silica a carcinogen? There is no evidence that the type used in food causes cancer to form. The EPA says silicon dioxide in its non-crystalline form poses "minimal risk" to humans. Although they are rare, side effects of silica are possible. This can include symptoms of an allergic reaction and possible digestive problems. One potential problem with nanoparticles found in food (which include silica in addition to compounds such as silver, titanium dioxide, iron oxide and zinc oxide) is that some studies suggest they may cause gastrointestinal problems, such as leaky gut syndrome and cell damage from prolonged DNA ingestion. More research is needed into these issues because, until now, we know little about the long-term effects of regular consumption of nanoparticles. Another difference needs to be noted here: the type of silica in food is different from crystalline silica, which is a component of soil, sand, granite, and several other minerals. Prolonged exposure to crystalline silica can harm the respiratory system, leading to lung-related injuries and illness. Hence, anyone in close contact with this compound must be handled carefully to prevent side effects. People most at risk of side effects from exposure to crystalline silica are those who work in the following industries: mining, steel, construction and sandblasting.
