History of nutrition

History of nutrition since the emergence of man on earth, the type of food that he has had to eat for sustenance, has varied over time, because he was forced to adapt to those closest to him had was easier to get with the few tools we had. As an example, please cite the studies on the remains of the oldest human found to date (we refer to the man of Atapuerca, Burgos). It has come to the conclusion that it was a scavenger and practiced cannibalism, and will play their “treats” with other animals with the same nutritional characteristics. In his walk in search of food, he would find new guys who are forced to adapt. The availability of large game was declining and had to feed on small game, shellfish (in some areas) and especially edible plants. This adaptive phase began about 100,000 years ago.The report cites, the last to suffer these restrictions, about 30,000 years ago, were the inhabitants of some very specific areas (two areas of the Middle East). However, in the Iberian peninsula less than 20,000 years ago (Freeman, 1981) meat still accounted for over 50 of the diet. 12,000 years ago (Cavalli-Sforza, 1981 Trowell, 1981) starts the first agricultural revolution. This meant a steady source of protein. We must take into account the great variability in the figures in the crops, which leads to irregular eating and famines. The end result of the collections it was very affected by the weather, against which was very difficult to fight. The storage of surplus in good years of production, it was not the most effective. Which caused an irregular supply. Slowly the type of support was varied until today, where the knowledge of the subject is greater. But the issue is not closed yet.Continue studies for better understanding and to provide appropriate solutions. Humans have evolved as omnivorous hunter – gatherers over the past 250,000 years. The early modern human diet varied significantly depending on location and climate. The diet in the tropics tend to be based mainly on plant foods, while the diet at higher latitudes tended more towards animal products. The analysis of cranial and post cranial remains of humans and animals in the Neolithic, with detailed studies have shown that modified bone cannibalism was also present among prehistoric humans . Agriculture developed about 10,000 years ago in multiple locations throughout the world, providing grains such as wheat, corn rice and staple foods such as bread and pasta. Farming also provided milk and milk products, and increased markedly the availability of meat and plant diversity.The importance of the purity of food was recognized when bulk storage led to demonstrations and pollution risks. Cooking is often developed as a ritualistic activity, due to the concern for efficiency and reliability, requiring adherence to strict recipes and procedures, and in response to the demand for purity and consistency in the food . From ancient times until 1900 The first experiment is a registered nutritional found in the Bible in the book of Daniel. Daniel and his friends were captured by the king of Babylon during the invasion of Israel. Selected as court servants, they would participate in the fine food and wine of the king. However, they objected preferring vegetables (pulses) and water in accordance with Jewish dietary restrictions. The administrator of the king reluctantly agreed to a study. Daniel and his friends received their diet for 10 days and were then compared with the King’s Men. Looking healthier were allowed to continue with your diet. 475 BCBC: Anaxagoras states that food is absorbed by the human body and therefore contains “homeomerics” (generative components), thereby deducing the existence of nutrients. 400 a. BC: Hippocrates said, “Let food be your medicine and medicine be your food.” 1500: the scientist and artist Leonardo da Vinci compared metabolism to a burning candle. 1747: Dr. James Lind, a British naval doctor conducted the first scientific nutrition experiment, discovering that lime juice saved from scurvy (a deadly and painful bleeding disorder) to the sailors who were at sea for years. The discovery was ignored for 40 years, after which British sailors became known as “lime trees.”
