In the modern world with a wide variety of useful and harmful food, presented in the windows of supermarkets, there is a need to study the effect of certain products on the human body.
Nutriciology - from the Latin "food". Explores everything related to food.
The science of nutrition is conditionally divided into two subsections,the first of which is engaged in the study of food, its chemical composition, and so on. The second subsection finds out the practical part of the issue in human nutrition.
Nutrition Science
Nutriciology is a science that studies issues.power supply. General Nutrition Research explores the composition of food products, the processes of interaction of various types of food, the course of consumption, as various substances from food affect the human body. In addition, nutriciology is a science that studies substances and actions that are detrimental to a normal state due to malnutrition.
Nutriciology as a science interacts with the following disciplines:
- Chemistry.
- Biochemistry.
- Cooking
- General food hygiene.
- Preventive medicine.
Today there is an opportunitygraduate from nutrition courses. Anyone can complete courses. It is also possible to contact the nutrition centers, which, at the cellular level, will reveal all diseases and pathologies in humans.
Nutrition, Nutriciology - is there a difference
I would like to immediately distinguish between two completely different, but interacting sciences - nutritiology and dietology.
Нутрициология - это наука, изучающая питание.And dietetics is a section of medicine that researches and organizes human nutrition. That is, for nutriciology, the main object of study is the process of absorption of substances. While dietetics is aimed at creating meals that include proper and healthy food. Therefore, the system of individual nutrition was called diet.
Nutriciology, in turn, seeks to study how the food itself and its consumption processes affect a person.
Basis of nutritional science
Nutriciology 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 consumption.
- The discrepancy between these two indicators will resulteither to obesity or to malnutrition. Both have a negative effect on the body, and cause a number of serious diseases (impaired locomotor system, heart function, etc.).
- The second law - the chemical composition of food must meet the needs.
- The human body is able to accumulate from foodonly fat. That is why people need daily use of healthy minerals and substances that are part of the food. Healthy food is the basis of the normal functioning of the human body.
Subjects of study nutritiology
The main subject of the study in nutrition is the search for ways to reduce the negative impact of food on the human body. Therefore, it is conventionally divided into three types:
- Exploring ways to improve the quality of food from the environment.
- The process of digesting food is already inside the body.
- Human exposure to foodborne substances.
Objects of science
The objects of the study of nutriciology are sources of nutrient replenishment and dietary supplements, among which are:
- raw materials used for the preparation of food products.
- natural food and its chemical content
- nutraceuticals, zubiotics, parapharmaceutics.
Tasks
The main tasks that science sets itself (nutriciology):
- Interaction with other sciences studying nutrition.
- The study of the role of substances coming from food.
- Eliminate nutritional deficiencies with a balanced diet.
- Drawing up a nutritional program
- Normalization of the work of the human body, changed by diseases.
- Excretion of various toxic substances from the body.
- Optimization and improvement of methods for the study of nutriciology subjects.
- Conduct a variety of tests to determine at the cellular level the effect of food on humans.
- Analysis of the effects of diet and dietary supplements on health.
- Study of the effect of drugs on humans.
- The study of changes in eating behavior in mental disorders.
Purpose of Nutriciology
Given all the shortcomings of nutrition and lifestyle of a person, this science has the following goals:
- The study of the effect of food on the body.
- The search for simpler ways of processing, destruction and removal of food from the body.
- The study of the motives for the choice of a particular food man. Research on the pattern of food choices.
Directions
Science develops in such directions as:
- Planning and making food.
- The process of metabolism.
- Food - as prevention and treatment for the human body.
Principles of science and proper nutrition
Nutriciology is a science that studies all the processes of interaction between man and food.
Therefore, it is engaged in the promotion of healthy eating. Highlights the following principles:
- Drinking at least two liters of pure water daily (tea, coffee, broths and similar liquids are not counted)
- During the painful sensations do not eat. It is better for some time to refuse to eat and drink more liquid.
- To eat only with the appearance of hunger.And in order not to confuse the uncontrollable appetite and the real need for food, it is necessary thirty minutes before a meal to drink a glass of pure water at room temperature.
- Discard water during meals.Since the drunk liquid leaves the human body in ten minutes, taking with it the gastric juice. Thus, the food does not have time to recycle and simply delayed. As a result, a person becomes overweight and health problems.
- Too hot and cold dishes are contraindicated. Food with a high temperature upsets the work of the digestive organs, and with a low one it slows down.
- Drinking coffee, tea, cocoa, chocolate and other products based on purine components, alloxur bases, should be moderate.
- It is necessary to abandon refined foods (sugar, flour, butter, and so on).
- The positive impact of eating raw seeds, nuts, vegetables and fruits.
- It is advisable to start every morning with fresh fruit and a couple of walnuts.
- In the lunch menu, one of the dishes should be presented in the form of a salad of fresh vegetables. So the human body will be saturated with useful and essential vitamins and minerals.
- Prerequisite - all ingredientsmust be raw. Also in the salad is not recommended to include salt, vinegar, oil, seasonings and the like. In this dish should be no more than four ingredients.
- Careful control over the use of animalsfat, because they slow down the digestive process. Plus, the load on the kidneys and liver increases. Fats should be added to food only after its preparation. And the ratio of animals to vegetable fats should be one to three.
- Food, subjected to heat treatment, must be combined with raw. So, for example, you need to eat six tablespoons of fresh vegetable salad for two spoons of cereal.
- Тщательным образом пережевывать пищу.By following this simple rule that we all have been told about since childhood, you will save your body’s forces on the digestive processes. Well-chewed food is faster digested and absorbed by the body. It should be noted that not processed food does not give in to rotting and fermentation processes, as a result becomes overweight.
- For the stomach is useful to arrange occasionally fasting days.
- Eat small portions.So less likely that you transfer too much. Excessive volume of food will force the stomach to work harder. And work for wear has not led to anything good.
- Reduce the amount of used salt. It is better to replace the marine. Replace table salt can also garlic, onions, horseradish.
- The most important principle of nutrition is to cook with fresh and natural products.
