Most edibles in a supermarket you can just wolf down. Some things to consider: -If you use dried beans, soak them overnight and boil them for an hour. Discard the water. You'll save yourself stomach pains this way. -Do not eat uncooked wheat. Your stomach will thank you. -Do not eat potatoes with green bits. They're a bit toxic. -If the vacuum-sealed packaging meat comes in is starting to bulge, pick another package. The meat is releasing gases in the initial stages of spoiling. (Probably still fine to eat,cooked) -Wash your vegetables. Soil bacteria can give you a bad time, although the risk isn't terribly high. In some countries, human excrement is still used for fertilization - this carries a risk of Hepatitis C and you want to heat the produce properly before consumption. -If it smells off or tastes bad, don't eat it! I can't think of anything else off the top of my head. This list is already full of "very unlikely to give you trouble" items as is. Have fun cooking!
