Food is very important to sustain life, and contains background material plays an important role in maintaining human life.

What are the basic components of food?
Is called the nutrient or nutrients that work to provide the body the required energy and materials needed for tissue building and repair and its importance in the organization of biological processes within the body and protects the body from infectious diseases, and because the human body can not manufacture these items, therefore it is necessary to put on it by food safety and continuity.
And these nutrients are divided into six sections, namely:
* Carbohydrates (sugars)
* Lipids (fats and oils)
* Proteins
* Water
* Vitamins
* Minerals
Vary the proportion of nutrients for different type of food, but they are often a mixture of most food products are for example, milk contains proteins and fats, and vitamins, minerals and water, whereas rice contains carbohydrates, proteins and fats, and vitamins and minerals and water.



The daily need of food:
Andmaalmana that the nutrients essential to human health must know the quantity that we need them to meet our daily needs. Therefore, these quantities can be determined through the different stages of life and by sex and physiological status (pregnancy and lactation). And is determined by the amount of food needed by the person by age, sex, height and muscular activity (nature of the work) and health status and then translate these needs of different nutrients to the diet daily and divided by the three main meals a day to two meals and two small.
Increasing interest in the world of health care day after day, and there is great interest and clear for the role played by certain foods for the prevention of some chronic diseases and dangerous.
And in general can be summarized as percentages of recommended nutrients in the diet daily, which should be guided by her dietitians when planning a meal integrated as follows:
* Carbohydrates: ranges between 55-60% of total calories
* Fiber: from 20-30 grams ? today
* Fat: 25-35% of the total calories, not to increase the proportion of saturated fat to 7% of total calories, the fat is saturated Vnsptha 20% between single-and multiple saturation.
* Protein: 10-15% of the total energy.

Carbohydrates:
Is the main source to provide you with the required energy of the movement and work and life as it gives one gram of carbohydrate 4 calories, which is about carbohydrates and sugars that are found in foods are many, such as bread and pasta, rice, dry beans, peas, potatoes, grains, vegetables and fruits.
Carbohydrates are divided into:

* Single sugars: simple sugars are called and are found in fruits, honey and corn.
* Sugars Ina?ah: found in cane sugar and molasses and sugar beet and fruit and vegetables and milk and barley.
* Complex sugars: include starch, found in grains and legumes, tubers, and the fiber Vengdaa in legumes, vegetables and nuts and whole grains and fruits.
Food needs of sugars:
Usually recommended to eat 100 grams of carbohydrates a day at least.

Lipids:
Lipids include fats (solid) and oils (liquid), a rich source of energy Valgram one gives 9 calories and contains essential fatty acids and fat soluble vitamins.
There are different types of dietary fat, namely:
* Trans fats are either monounsaturated fat are found in olive oil and canola in most vegetable oils, or be a fat multi-unsaturated and are found in sunflower oil and seed oil, cotton, flax oil and soybean oil and corn oil and oil rapeseed oils and some fish, the body needs to help him in the formation of coated membranes for each cell of the body.
* Saturated Fat: working to raise the level of cholesterol in blood and human harmful if ingested in large quantities and are found in animal fat and whole milk and whipped butter, chicken and some vegetable oils such as coconut oil and peanut oil and palm oil.
* Cholesterol: There is only in animal foods such as brain and egg yolk and fish eggs, caviar, liver, heart, kidneys and pancreas and butter and cream and cheese and full cream milk and chicken skin. Advised not to eat large quantities because it raises the level of Alkolsterolbaldm.
You should deal with small amounts of foods rich in saturated fat and Balkolsterol you should read the facts food label for products that tell you about the content of fat. Some fats are rich in omega-3 fatty acids are found in fish oil and flax seed and prevent hardening of the arteries and inflammation of the joints and can be found in watercress.
Food needs from fat:
For women must address the lady in the middle of the 60-75 grams of fat The men they can reach to 90 grams, and cholesterol should not be more than 300 mg ? today.

Proteins:
Of nutrients is very important, as they enter the building in various tissues of the body and maintenance, and the intervention in the installation of some hormones and enzymes, and without it could not happen to life on the planet.
Proteins are made up of 22 structural units containing nitrogen and amino acids are called proteins differ from each other for different number of amino acids and followed up, giving each gram of protein 4 calories.

Proteins are divided according to the characteristics of food:
* Complete proteins (proteins of high quality) are proteins containing all essential amino acids and in sufficient quantities to ensure the needs of the body of the crisis, growth and maintenance of damaged tissue. Examples include all animal proteins (except gelatin) protein such as eggs, milk, meat, fish and poultry.
* Protein is complete (proteins with low quality) are proteins lacking valine or more and be the amount of acid which is insufficient to ensure the body's need, and its example plant proteins including wheat and rice, pulses, seeds and other with the exception of soybean is one of the complete proteins.
* Partially complete proteins: they contain a limited amount of basic amino acids and as a result are able to maintain life, but not conducive to growth. Such as some cereals, legumes, nuts, and help eat cereals and pulses together in the production mix sufficient for the manufacture of protein in the body.

Food needs of the proteins:
Needs an adult to about 0.52-0.57 grams of protein per Cgram weight per day and needs of the child at the stage of growth, 2.5 g protein per Cgram of weight a day as well as in adolescence.

Water:
Water is essential nutrient for humans as it is an essential component of all tissues of the body, water helps to regulate body temperature and the transfer of nutrients to the cells and waste products out of them. And you need to drink eight glasses of fluids a day to compensate Matvkdh
