Basics of Nutrition

The basis of nutrition is information about the process of nutrition in general, the approach to this issue from different sides.

Fundamentals of Nutrition: What is the diet and its functions?

Food is a source of energy and necessary nutrients. The process of nutrition provides the body's needs for building materials, energy, and biologically active substances.

Nutrition in terms of physiology

Nutrition is inextricably linked with the physiological side of the question: what is the digestive system and how is digestion.

Nutrition is a whole complex of processes, consisting of absorption, digestion, absorption and assimilation of nutrients. It begins in the mouth and ends in the large intestine and is a fairly complex system.

Food: information on basic nutrients, harmful and useful products, industrial technologies

The human body needs in various quantities the basic components of nutrition: proteins, carbohydrates, vitamins, fats, minerals, water. Therefore it is important to know the relationship, volume and role of these nutrients in the diet.

The harmful products are mainly food created by people. These are processed, modified and containing food additives products. For example, sausage, carbonated drinks, products with trans fats (baked goods, margarine, refined oils), etc. can be mentioned as an example. Figuratively about harm it is possible to tell the following: to the organism the defective material is offered, as a result of mastering of which biological structures with a defect are synthesized, diseases develop.

Among modern production technologies, we can designate: emulsification, pasteurization, hormonal administration, refining, preservation, etc. We will cite negative examples.

In order to obtain refined oils for full spin, an organic solvent is used, since it has low cost and high efficiency.

The refining process extracts from the products necessary for the body ballast substances. During the production of cereals (white wheat flour), vitamins, minerals, proteins are lost, gluten and starch remain.

Diet

The diet is a complex concept. This is the amount and time of meals, the process of distribution by mass, chemical composition, food set, energy value and how a person behaves during a meal.

The correct diet regimen saves energy, improves digestion of food, reduces the calorie content of the diet.

Basics of Nutrition: Cooking food at home

It is important to have an idea of the most optimal cooking technologies.

You should prepare food for a long time at a low temperature. This can be cooking, stewing, steaming. When a dish is cooked at very high temperatures (on a grill above 260 degrees Celsius), toxic chemicals are synthesized - heterocyclic amines, damaging DNA and triggering the mechanism of oncology development. A similar situation is with baking. High temperature causes the glycation process: toxins are produced, synthesizing free radicals and increasing inflammatory processes in the body.

Fundamentals of nutrition: systems, concepts and theories of nutrition

Currently, there are many theories and nutrition programs : functional nutrition, balanced, adequate, vegetarian, etc. Each person is able to organize their own diet in accordance with scientific developments. This will require studying the information, recommendations, pluses, minuses, principles, etc.

Always there is an opportunity to address to the help of the nutritiologist or the dietician for competent construction of process of a delivery.

Nutrition problems

It is necessary to take into account the existing problems in the field of nutrition - a chronic lack of vital nutrients and the accumulation of toxic, harmful elements in the human body.

Scientists have found a way to solve this problem - to fill the deficit. BAD (biologically active additives) have been developed, which have been successfully used for many decades in the developed countries of the world.

In conclusion, it can be said that the basics of nutrition are information about nutrition problems and methods of their solution, about systems, concepts and theories of nutrition, about modern production technologies, about cooking food, about harmful and useful products, about nutrients, digestion physiology and functions Power supply.
