Food Additive

Shit they put in "food" that usually promotes fat gain, obesity, and health issues. They may include preservatives, flavorings, coloring, or whatever, though it's not a problem because it increases their profit margin, and makes fat people more satisfied by the taste. However, food additives may be a "necessary evil" at times.

The FDA approved another food additive under "generally recognized as safe(GRAS)," though I get the feeling it'll make you a fatass.
