Part 172: Food additives permitted for direct addition to food for human consumption. Silicon dioxide, also known as silica, is a chemical compound commonly used in food as an anti-caking agent or in cosmetics to prevent corrosion, according to the USDA. lung-health-and-diseases/lung-disease-lookup/silicosis/silicosis-symptoms-causes-risk.html Silicosis symptoms, causes, and risk factors.

Silicon dioxide and certain silicates.(2010) fda.gov/food/ingredientspackaginglabeling/foodadditivesingredients/ucm094211.htm Overview of food ingredients, additives and colors.Calcium silicate and silicon dioxide/silicic acid gel added for nutritional purposes to food supplements.You can learn more about how we ensure our content is accurate and current by reading our editorial policy. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. More current research may be changing the guidelines and recommendations. This paper found the only negative health effects related to silicon dioxide have been caused by silicon deficiency. Previously guidelines followed a 1974 paper prepared in association with the World Health Organization. Their concerns focused on the nano-sized particles (some of which were smaller than 100 nm). In 2018, the European Food Safety Authority urged the European Union to impose stricter guidelines on silicon dioxide until further research could be done. Food and Drug Administration (FDA) has also recognized silicon dioxide as a safe food additive. In addition, studies have found no evidence that silicon dioxide as an additive in food can affect reproductive health, birth weight, or bodyweight. While many of the studies on silica have been done on animals, researchers have found no link between the food additive silicon dioxide and increased risk of cancer, organ damage, or death. This exposure and disease primarily occurs among people who work in: However, the progressive, often fatal lung disease silicosis can occur from chronic inhalation of silica dust. Instead, it’s flushed out by our kidneys. Research has shown that the silica we consume through our diets doesn’t accumulate in our bodies. The fact that silicon dioxide is found in plants and drinking water suggests it’s safe.
