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).
In situations where it is important to bring food and logistics of acquisition, storage and transport is therefore of importance, are sometimes used interchangeably as food, supplies. Plants are well on way to becoming the largest source of food for humans. Plant seeds are especially suitable as food because they contain important nutrients that contribute to seed sprouts.
Among edible seeds are grains (eg wheat, corn and rice), legumes (beans, peas and lentils) and nuts. Some seeds are also used to produce cooking oil, for example, walnuts, sunflower seeds, rapeseed, olive and sesame seeds.
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).
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.
The traditional diet pyramid recommend a low intake of fat and a high intake of carbohydrates in form of potatoes, pasta, rice and bread. The inverted pyramid diet recommended by American researcher Walter Willett. He recommends a high intake in form of plant oils and a low intake of carbohydrates from rice, potatoes, white bread and pasta. In this family, there are all minerals frequently used in manufacturing process. The most common is the Sodium Chloride (salt). This category is divided into inorganic salts (calcium, sodium, potassium) and trace elements (iron, magnesium, as appropriate, copper, cobalt, etc.).
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.
The food comes from animal husbandry, vegetable crops, gathering, fishing and hunting of wild animals. It varies according to quality of initial environment and culture or livestock, according to freshness of product, as any contamination (heavy metals, pesticides, biocides, microbes, radionuclides, etc.) or ruptures of cold chain. In most countries, more or less extensive control and monitoring systems exist, including for radioactive contamination.
