Silicon Dioxide


While eating a picnic at the beach, we do everything possible to keep sand out of our food, but fast food chains and grocery store products add it on purpose. This food additive, called silicone dioxide, is used as an anti-caking agent in meat-based products such as chili (including that sold by chains like Wendy's and Taco Bell). When not used in fast food, silicon dioxide can be found in cement, ceramics, glass and, of course, between your toes during a day at the beach.
