Nutrition is a science that studies human nutrition. Healthy food

In the modern world, with a wide variety of useful and harmful food presented in supermarket display cases, it became necessary to study the influence of certain products on the human body.

Nutrition is from the Latin "food". Explores everything related to food.

The science of nutrition is conventionally divided into two subsections, the first of which deals with the study of food, its chemical composition, and so on. The second subsection clarifies the practical part of the question in human nutrition.

Nutrition Science

Nutrition is a science that studies nutrition. General nutritiology examines the composition of food products, the processes of interaction of various types of food, the course of use, how various substances from food affect the human body. Among other things, nutritional science is a science that studies substances and actions that harm the normal state due to malnutrition.

Nutrition as a science interacts with the directions of the following disciplines:

• Chemistry.
• Biochemistry.
• Cooking.
• General food hygiene.
• Prophylactic medicine.

To date, it has become possible to complete courses of nutriciology. Anyone can finish the course. Also there is an opportunity to apply to the centers of nutritional science, which at the cellular level will reveal all diseases and pathologies in humans.

Dietology, nutriciology - is there a difference

I would like to immediately distinguish two completely different, but interacting sciences - nutritiology and dietology.

Nutrition is a science that studies nutrition. A dietology is a section of medicine that examines and organizes human nutrition. That is for nutritiology, the main object of study is the process of absorption of substances. While dietetics is aimed at creating meals that include healthy and healthy food. Therefore, the individual food system was called a diet.

Nutrition, in turn, seeks to explore how the food itself and the processes of its consumption affect man.

Basis of Nutrition Science

Nutrition is based on the laws of nature:

• The first law of nature - the energy value of food, eaten by a person, must be equal to its energy costs.
• The inconsistency of these two indicators will lead to either obesity or malnutrition. Both that and another negatively affects the body, and causes a number of serious diseases (violation of the musculoskeletal system, heart function, and so on).
• The second law - the chemical composition of food must meet the needs.
• The human body can only accumulate fat from food. That's why people need daily use of useful minerals and substances that are in the composition of food. Healthy food is the basis of the normal functioning of the human body.

Subjects of the study of nutritiology

The main subject of the study of nutritiology is the search for ways to reduce the negative impact of food on the human body. Therefore, it is conditionally divided into three types:

• Study of ways to improve the quality of food from the environment.
• The process of digesting food is already inside the body.
• The effect on humans of substances supplied with food.

Objects of science

Objects of research of nutritiology are sources of replenishment of nutrients and dietary supplements, among which:

• Raw materials used for cooking food.

• Natural food and its chemical contents
• Nutraceuticals, zubiotics, parapharmaceutics.

Tasks

The main tasks that science sets itself (nutriciology) are:

• Interaction with other sciences that study nutrition.
• Investigation of the role of substances supplied with food.
• Eliminate the lack of nutrients through a balanced diet.
• Preparation of a nutrition program.
• Normalization of the work of the human body, altered by diseases.
• Excretion of a variety of toxic substances from the body.
• Optimization and improvement of methods of research of subjects of nutritiology.
• Conducting a variety of tests to determine the effect of food on a person at the cellular level.
• Analysis of the impact of dietary nutrition and dietary supplements on health.
• Study of the effects of drugs on humans.
• Study of changes in eating behavior in mental disorders.

The purpose of nutrition

Considering all the shortcomings of human nutrition and lifestyle, this science sets the following goals:

• Study the effect of food on the body.

• Search for simpler ways of processing, destroying and removing food from the body.
• Studying the motives for choosing a particular food by a person. Research on the question of what scheme is the choice of food.

Directions

Science develops in such directions as:

• Planning and making food.
• The process of metabolism.
• Food is like prevention and treatment for the human body.

Principles of science and nutrition

Nutrition is a science that studies all the processes of human-food interaction.

Therefore, she is engaged in the promotion of healthy eating. Allocates the following principles:

• Daily drink at least two liters of clean water (tea, coffee, broths and similar liquids are not included in the calculation)
• During painful sensations, do not eat. It is better to give up food for a while, and drink more liquid.
• Eat only when there is a feeling of hunger. And in order not to confuse the uncontrollable appetite and the real need for food, you need to drink a glass of clean water at room temperature thirty minutes before eating.
• Refuse water during meals. As the liquid drains out the human body after ten minutes, taking with it the gastric juice. Thus, the food does not have time to be recycled and simply postponed. As a result, a person has excess weight and health problems.
• Contagious to eat too hot and cold dishes. Food with a high temperature upsets the work of the digestive organs, and with a low one it slows down.
• Consumption of coffee, tea, cocoa, chocolate and other products, based on purine components, alloxuric bases, should be moderate.
• It is necessary to refrain from refined food products (sugar, flour, butter and so on).
• A positive impact is the consumption of raw seeds, nuts, vegetables and fruits.
• It is advisable to start every morning with fresh fruits and a couple of walnuts.
• In the lunch menu, one of the dishes should be presented as a salad of fresh vegetables. So the human body will be saturated with useful and necessary vitamins and minerals.
• A prerequisite - all the ingredients of the dish should be raw. Also in the salad is not recommended to include salt, vinegar, oil, seasonings and the like. In this dish should not be more than four ingredients.

• Careful control over the consumption of animal fats, because they slow down the process of digestion. Plus, the load on the kidneys, the liver increases. Fats should be added to food only after cooking. And the ratio of animals to vegetable fats should be one to three.
• Food that has been cooked must be combined with raw food. So, for example, two spoons of cereal should be eaten six spoons of fresh vegetable salad.
• Thoroughly chew food. Carrying out this simple rule, which we all have been told since childhood, you will save the forces of your body for digestive processes. Well chewed food is quickly digested and absorbed by the body. It is worth noting that unprocessed food does not respond to the processes of putrefaction and fermentation, as a result becomes overweight.
• It is useful for the stomach to arrange occasional days of rest.
• Eat in small portions. So there is less likelihood that you will overeat excess. Excess volume of incoming food will force the stomach to work harder. And the work on weariness did not lead to anything good.
• Reduce the amount of table salt used. It's better to replace the sea. Replace table salt also can garlic, onions, horseradish.
• The most important principle of nutritiology is to prepare from fresh and natural products.
