Food is any substance consumed to provide nutritional support for an organism.  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 to provide energy, maintain life, or stimulate growth. A drug is any substance (other than food that provides nutritional support) that, when inhaled, injected, smoked, consumed, absorbed via a patch on the skin, or dissolved under the tongue causes a physiological change in the body. Intradialytic parenteral nutrition (IDPN) is a nutritional support therapy (medical nutrition therapy) for people on hemodialysis who have a difficult time maintaining adequate nutrition.  It is administered directly into the bloodstream of patients suffering from chronic kidney disease (CKD) in an effort to decrease the associated morbidity and mortality experienced in patients with renal failure.  IDPN contains protein (amino acids), carbohydrates (dextrose), and fats (lipids) in an attempt to meet a patient's weekly nutritional needs.  Solutions can be individualized for each patient based on weight, needs, medical history and enteral intake.

A vitamin is an organic compound and an essential nutrient that an organism requires in limited amounts.  An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term "vitamin" is conditional upon the circumstances and the particular organism.  For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animals.  Vitamin D is essential only for people who do not have adequate skin exposure to sunlight, as ultraviolet light promotes synthesis in skin cells.  Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.
