2. Sand (silicon dioxide)
Avoiding sand in your sandwich at the beach is obvious, avoiding sand in your restaurant-purchased meal may not be so apparent.

Silicon dioxide, also known as silica (also known as sand!), is used to make glass, optical fibers, ceramics, and cement. Oh, and chili. Used as an anti-caking agent, it is often added to processed beef and chicken to prevent clumping, and is listed in the ingredient panels for chili from both Wendy’s and Taco Bell. Most experts suggest that it isn’t harmful for consumption, but just know that the ingredient keeping that chili meat nice and non-caking is the also the primary component of diatomaceous earth, commonly used as a pesticide.

Have you ever actually looked at a Jack in the Box taco before you eat it?
I can't identify much of anything other than the lettuce...(I think it's lettuce....)
