Humans are omnivores that eat a variety of foods, and cultivation of cereals and production of bread has made up a key component of human nutrition since the beginning of agriculture. Nutrition in humans is balanced with eating for pleasure, and optimal diet may vary depending on each person's demographics and health concerns. In nutrition, a lack of just one essential nutrient can cause bodily harm, just as an overabundance can cause toxicity. A balanced diet includes appropriate amounts of all essential and non-essential nutrients. The science of nutrition identified thiamine as the first vitamin to be chemically identified in 1926, and vitamin C as a protection against scurvy in 1932. The role of vitamins in nutrition was studied in the following decades.
