Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
Garlic breath is halitosis (bad breath) resulting from the consumption of garlic.
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach and liver. Out of the many compounds, allyl methyl sulfide (AMS) does not break down quickly and remains in the body in significant amounts hours after consumption, resulting in an odor that can last for hours to days. AMS is the only one of the garlic-derived organosulfur compounds detectable in the lungs or urine, as well as the mouth, which means that AMS is reabsorbed into the blood stream and travels to other organs for excretion - namely the lungs, kidneys and skin.
