In 475 BC Anaxagoras argued that the food there are principles which are absorbed by human body and used as components "generative" (a first intuition of existence of nutrients). In 400 BC Hippocrates said. In 1747 the English physician James Lind conducted the first experiment of Nutrition, found that lemon juice was able to cure scurvy. Only in 1930s it was discovered that this property was due to vitamin C in lemons (best cooking sheet).
Some simple molecules like glucose are assimilated by high digestive tract for absorption by mucous membranes. Thanks to digestive process, the more complex molecules are broken down so that their constituents simple can cross the intestinal wall, enter the bloodstream, and therefore, reach the individual cells.
It defines food any substance or mixture of substances in any state of matter and structure assimilated by a living organism for their nutrition. Food, food and nutrition, are often used as synonyms and, at least in sense on Food, indicate everything we eat and drink for the physical sustenance.
Fruit is in botanical sense proliferation device with flowering plants. Many plants have developed fruits which are important nutritional sources for humans and animals. When animals eat the fruit, they also contribute to spread the seeds. Fruits form a substantial part of content of diet in most cultures. Animals make as a direct food source by meat, internal organs or blood is used for human consumption. A few animals are also used as indirect food sources, for example for the production of milk (goats, cows, sheep, and camels), and eggs (chickens, ducks and geese).
The diet of an organism, is what he eats or takes. In heterotrophic organisms higher, subject to availability of food, the diet is largely determined by perception of attractiveness of food. The molecules that compose the food is converted into energy, through the mediation of TP, to serve as material for the formation of biological tissues and catalyze chemical reactions within body, and to be accumulated and / or converted as reserves in other substances.
In addition, the salt is often eaten as a condiment, baking soda and some other inorganic salt is used in preparation. These are inorganic substances, which together with water, form an important part of human diet. The synthesis of food is a new frontier, and represents a further diversification of origin of food. Vitamins, supplements, additives are still often of synthetic origin.
There are about 2,000 species of plants that are grown for feeding. Most of all plant foods consumed by humans, for the fact of serving as a reserve for the development of plant are the same seeds. These include cereals (corn, wheat and rice) and legumes (beans, peas and lentils). Some seeds are often used, squeezing, to produce oils, including sunflower, canola and sesame. Fruits are a product matured provided by some plants. The fruits attract animals and make up a significant part of diets of most cultures. Can help provide significant energy contribution to wealth of carbohydrates (banana, plantain). Certain fruits, like pumpkin and eggplant, are used and eaten as vegetables.
Among the foods are vegetables: root vegetables (carrots) and tubers (potato, cassava), fresh vegetables (spinach and lettuce), the vegetables with the stem (sprouts and asparagus, vegetables inflorescence (like artichokes and broccoli), algae. The meat is produced for subsequent phases: from breeding sites to abattoir for slaughter, where you do the demolition, the appenditura, the division and representation. This preparation is usually performed in slaughterhouses. Many countries regulate slaughterhouses according to a specific humanitarian law. For example, the United States has established the Humane Slaughter Act in 1958, requiring the stunning of before his killing.
