The need to study the effect of various foods on the human body has arisen due to the current variety of harmful and healthy foods. Nutritionology studies everything related to food and nutrition.
Nutrition and dietetics are the same?
It is worth mentioning right away that there is a huge difference between nutrition and nutrition. In the first case, we are talking about a science that studies food. As for dietetics, it is the medical branch that organizes and studies human nutrition.
In other words, the process of absorption of components from food and drinks by the human body will be the key object of study for a nutritionist. Whereas nutritionists create diets consisting of healthy and proper food.
Subdivisions of Nutrition
Nutritionology can be roughly divided into several types:
- The first type studies the practice of nutrition.
- The second view considers food, its chemical composition, etc.
Nutritionology needs to interact with many related areas, such as:
- Preventive medicine and general nutritional hygiene
- Cooking
- Biochemistry and chemistry
Whole courses of nutritional education are currently being conducted. In higher educational institutions you can get the profession of “nutritionist”. In addition, there is an opportunity to become a client of the Nutrition Clinic: specialists will identify all pathologies and diseases of the applied client at the cellular level.
So, the subject of the study of science is divided into the following components:
- Healing and preventive effects of food on the human body;
- Digestibility of food by the body;
- Formation and growth of food in nature.
Nutritionists pay great attention to the irreplaceable essential elements of food. That is, those that are able to enter the human body exclusively with food (our body cannot synthesize them on its own). These are selenium, zinc, choline, etc. The lack of such components causes serious pathologies.
The most important nutritional elements, the presence of which is really important for the state and normal functioning of the entire human body:
- Minerals, trace elements and vitamins;
- Carbohydrates;
- Fats and lipids;
- Proteins.
Another most significant object of study of nutritionists is acid-base balance.
Tasks and achievements of science
The global challenge of nutritional science is to determine the impact of malnutrition (when some components are lacking in the diet, and some are too many) on the human body and longevity.
In addition, representatives of this science are looking for ways to restore health and prevent the development of all kinds of diseases by cleaning the body and eliminating the lack of especially important macro- and micronutrients using an established nutrition system.
Nutritionology is inextricably linked with dietary supplements. Since, in fact, the complexes of additives are also food. According to nutritionists, a properly selected complex of dietary supplements can balance a person’s nutrition.
Key goals of science:
- Study of the relationship between eating behavior and human mental health;
- Carrying out clinical studies aimed at a complete and high-quality study of the effects of food intake at the cellular and bionic levels. Nutritionists also study the physiological effect of dietary supplements and dietary components on the life and health of sick and healthy people;
- The search for methods of increasing the body’s immunity to infectious diseases;
- Issues of elimination of “toxins”, detoxification of the body, prevention of oncology and cardiovascular diseases with the help of proper nutrition;
- Correction of diets taking into account various chronic pathologies;
- Finding ways to eliminate the lack of vital macro- and micronutrients with the help of well-established nutrition.
If you want to get a balanced and competent daily diet, then you should contact a nutritionist for this. The specialist will study your needs on an individual basis and indicate what exactly your body lacks. So, if you constantly want to eat something sour, it means that you have a lack of ascorbic acid, and you will be advised to use such healthy foods.
