In the modern world, with a wide variety of he althy and unhe althy food presented in supermarket windows, it became necessary to study the effect of certain products on the human body.
Nutritiology - from the Latin "nutrition". Explores everything related to food.
The science of nutrition is conditionally 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 issue in human nutrition.
Nutrition Science
Nutritiology is the science of nutrition. General nutrition studies the composition of food products, the processes of interaction of various types of food, the course of consumption, how various substances from food affect the human body. Among other things, nutrition is a science that studies substances and actions that harm the normal state due to malnutrition.
Nutritiology as a science interacts with the directions of the following disciplines:
- Chemistry.
- Biochemistry.
- Cooking.
- Generalfood hygiene.
- Preventive medicine.
Today, it became possible to complete courses in nutrition. Anyone can complete the course. It is also possible to contact the centers of nutrition, which at the cellular level will reveal all diseases and pathologies in humans.
Dietology, nutrition - is there a difference
I would like to immediately distinguish between two completely different, but interacting sciences - nutrition and dietology.
Nutritiology is the science of nutrition. And dietetics is a branch of medicine that studies and organizes human nutrition. That is, for nutrition, the main object of study is the process of absorption of substances. While dietetics is aimed at creating meals that include proper and he althy food. Therefore, the system of individual nutrition was called a diet.
Nutriciology, in turn, seeks to study how food itself and the processes of its consumption affect a person.
The basis of nutrition science
Nutritiology 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 his energy consumption.
- Mismatch between these two indicators will either lead to obesity or malnutrition. Both have a negative effect on the body, and cause a number of serious diseases (impairment of the musculoskeletal system, heart function, and so on).
- Second law - the chemical composition of food must meet the needs.
- The human bodycan only store fat from food. That is why people need a daily intake of useful minerals and substances found in food. He althy food is the basis for the normal functioning of the human body.
Nutritiology studies
The main subject of study of nutrition is the search for ways to reduce the negative effects 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 digestion is already inside the body.
- Human exposure to substances from food.
Science Objects
The objects of research in nutrition are sources of replenishment of nutrients and dietary supplements, including:
raw materials used to make food products
- natural food and its chemical content
- nutraceuticals, zubiotics, parapharmaceuticals.
Tasks
The main tasks set by science (nutrition):
- Interaction with other nutritional sciences.
- Research on the role of dietary substances.
- Fix nutritional deficiencies with a balanced diet.
- Create a nutrition program.
- Normalization of the human body, modified by diseases.
- Removal of various toxic substances from the body.
- Optimization andimproving the ways of researching subjects of nutrition.
- Performing 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 he alth.
- Studying the effect of drugs on humans.
- Eating behavior change study in psychiatric disorders.
The Goal of Nutrition
Given all the shortcomings of human nutrition and lifestyle, this science sets itself the following goals:
Studying the effect of food on the body
- Finding easier ways to process, destroy and remove food from the body.
- The study of the motives for the choice of a particular food by a person. Research into the pattern of food choices.
Directions
Science is developing in such directions as:
- Planning and preparing food.
- The metabolic process.
- Food - as prevention and treatment for the human body.
Principles of Science and Nutrition
Nutriciology is a science that studies all the processes of interaction between humans and food.
That's why she promotes he althy eating. Emphasizes the following principles:
- Drink at least two liters of pure water daily (tea, coffee, broths and similar liquids are not included in the calculation)
- During the pain, do not eat. It is betterstop eating for a while and drink more fluids.
- Eat only when hungry. And in order not to confuse uncontrolled appetite and a real need for food, you need to drink a glass of clean water at room temperature thirty minutes before eating a meal.
- Refuse water while eating. Since the drunk liquid leaves the human body after ten minutes, taking gastric juice with it. Thus, the food does not have time to be processed and is simply postponed. As a result, a person becomes overweight and has he alth problems.
- Too hot and cold dishes are contraindicated. Food with a high temperature upsets the work of the digestive organs, and with a low temperature it slows down.
- Consumption of coffee, tea, cocoa, chocolate and other products based on purine components, alloxuric bases, should be moderate.
- Refined foods (sugar, flour, butter, etc.) should be avoided.
- Eating raw seeds, nuts, vegetables and fruits has a positive effect.
- 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.
- Mandatory condition - all components of the dish must be raw. Also, it is not recommended to include s alt, vinegar, oil, seasonings and the like in the salad. This dish should contain no more than fouringredients.
- Careful control of animal fats, because they slow down the digestion process. Plus, the load on the kidneys and liver increases. Fats should only be added to food after it has been cooked. And the ratio of animal to vegetable fats should be one to three.
- Food that has undergone heat treatment must be combined with raw food. So, for example, for two tablespoons of porridge, you need to eat six tablespoons of fresh vegetable salad.
- Chew food thoroughly. By following this simple rule, which we all have been told since childhood, you will save your body's strength for digestive processes. Well-chewed food will be digested and absorbed by the body faster. It is worth noting that unprocessed food does not succumb to the processes of decay and fermentation, and as a result becomes overweight.
- It is useful for the stomach to arrange fasting days from time to time.
- Eat small meals. This way you are less likely to overeat. Excess food intake will make the stomach work harder. And working for wear and tear has not yet led to anything good.
- Reduce the amount of table s alt you use. It is better to replace the sea. Garlic, onion, horseradish can also replace table s alt.
- The most important principle of nutrition is to cook with fresh and natural products.
