Etymology

Origin of nutrition

First recorded in 1375–1425; late Middle English, from Late Latin nūtrītiōn- (stem of nūtrītiō ) “a feeding,” equivalent to Latin nūtrīt(us) (past participle of nūtrīre “to feed”; see nourish ) + -iōn- -ion

Explanation

Nutrition is the study of food and drink. If you take a nutrition class, you'll become more aware of the health hazards of junk food. Nutrition also has a more general meaning — the source of materials needed to nourish your body, like vitamins, minerals, carbohydrates, fats, and protein. When you study nutrition, you learn the right combinations of these to have great health. You also gain an understanding of how the body uses food to produce energy, grow stronger and repair itself — this process is also called nutrition.
