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.
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. While originally it included plant morphology, which is the description of the physical form and external structure of plants, since the mid-20th century the investigations of plant anatomy are considered a separate, distinct field, and plant anatomy refers to just the internal plant structures. Plant anatomy is now frequently investigated at the cellular level, and often involves the sectioning of tissues and microscopy.
Sweet tea is a style of iced tea commonly consumed in the United States, especially the Southern United States. Sweet tea is made by adding sugar to bags of black tea brewing in hot water while the mixture is still hot. The tea is served ice-cold and plain but may also be flavored, traditionally with raspberry, lemon, or mint. Sweet tea can also be made with a simple syrup and is sometimes tempered with baking soda to reduce the drink's acidity.
Sweet tea is typically brewed with a lower carbohydrate and calorie content than most fruit juices and sugary sodas, but it is not unusual to occasionally find sweet tea with a sugar level as high as 22 brix (percent weight sucrose in water), twice that of Coca-Cola.

More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
