Food is an essential source of energy for both humans and animals. Humans and animals occupy mainly plants and meat. Animals that only eat plants are called herbivores, while people who only eat plants, fruits and vegetables called for vegetarians. Although many cultures sourced food by hunting and collection, procures most societies today food through farming and fishing, and hunting (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.
Vary the food is the first rule to eat properly, ensure the full contribution of elements necessary to nutrition and, at the same time, satisfy the quest for taste and pleasure.
In addition, several snacking. Breakfast is considered the most important meal because it will contribute to energy day must be instituted. Especially in weekend morning is part started eating brunch instead of breakfast and lunch. At the picnic allowed food and eating is called picnic or just lunch. It depends how much energy a person need. It is judged by age, body weight and physical activity. Exceeded the daily energy needs, you gain weight and you get less than required, you lose it. In this context, refers to "burn" kcal / kJ. A single chocolate bar can contain over 500 calories; it is 20-25% of energy a man of 19-30 years should have in a day.
From food the body extracts the useful substances to its metabolism. Are the nutrients, all or in part, depending on organism in question, essential to life. Cereal products; by end of Neolithic period onwards most energy intake of most of human population is a source of starchy. Cereals and other products of land rich in carbohydrates are variously processed to derive nourishment.
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.
Even animals, from cnidarians such as jellyfish, mammals, passing insects, molluscs and crustaceans, vertebrates, all are used as human food. Meat is an example of product made from muscle tissue or organs. Milk, cheese, butter, hand, constitute an example of animal products: birds, fish, and many other animals produce eggs, often edible, while the bees produce honey, a sweetener, popular in many cultures.
