When did people start eating healthily?
Human eating habits have evolved throughout history. Initially, our ancestors consumed fruits and seeds, as well as meat from animals they hunted.
800,000 years ago, they learned to use fire, which allowed them to chew better and make better use of the nutrients in plant and animal foods. Between 8,000 and 1,000 BC, agriculture and livestock emerged, with a diet primarily based on whole grains, complemented by small amounts of legumes, vegetables, dairy products, meat, fish, and seasonal fruits. Cereals were known for their high caloric value and became the main food of different cultures (corn in America, wheat in Europe, and rice in Asia).
Starting in the 19th century, with the Industrial Revolution, food availability increased, and more animal products were consumed. In the 20th century, nutrition as a science and epidemiological studies linking health to diet type began, such as the case of the Mediterranean diet or the adverse effects of unhealthy eating. Therefore, although the concept of eating well has been present in human history for a long time, the current notion of "eating healthy" as we know it today began to develop in the 20th century.
