Food poisoning occurs when you eat food contaminated with bacteria or other toxins. Symptoms include diarrhea, vomiting, and stomach cramps, and generally start 4 to 36 hours after eating contaminated food.

Food poisoning is especially common during summer when food may not be kept cold enough to prevent bacteria from growing.
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth.

Your breathing muscles consist of the diaphragm and muscles in the abdomen, chest, neck and shoulders. 70-80% of the inhaling should be done by the diaphragm so that your breathing is nice and deep. This has a couple of advantages:
