The Importance of Food Groups and Healthy Nutrition

It is important to adjust the carbohydrate, protein and oil fractions of energy as well as the nutritional diversity in a healthy diet. These percentages are predetermined and the ratios differ by age group. A healthy individual should receive 10-15% of energy from proteins, 55-60% from carbohydrates, and up to 30% from oils.
Nutrients: Nearly 70 nutrient items in the body that are needed and in the composition of the nutrients can be grouped into 5 groups according to their chemical structure and their activity in body adaptation. These; proteins, fats, carbohydrates, minerals, vitamins and water. the individual is able to provide all the nutritional items that are needed according to his / her age, gender and physiological condition in sufficient quantities.


Carbohydrates, fats and proteins are things that supply energy.
Carbohydrates: The total amount of carbohydrates in the adult human body is below 1%. The main task of carbohydrates is to provide energy. Most of the daily energy used in the body is provided by carbohydrates. In the human body, carbohydrates are stored in very small amounts as glycogen and, if necessary, released into the blood as glucose. Glycogen storage is mostly found in the liver and muscles, and there are also some glycogen in other organs. The glycogen, which is in the form of a tank, is required to maintain a certain level of blood glucose, the uninterrupted source of energy for body tissues.


Proteins: Approximately 16% of the adult human body is composed of proteins. They are also essential for the growth, development, renewal of worn-out cells since they are the essential element of cells besides their energy supply. Proteins also constitute the structure of enzymes and some hormones involved in the use of nutrients in the body. Some of the minerals are the building blocks of the body. Some of them, along with vitamins, act as regulators in the chemical changes in the destruction and construction of food items.


Oils: 18% of the adult human body is fat. In general, women have more fat in their bodies than men. Body fat is the main energy source of a person. When the energy is not enough, the body stores the fat and the fat rate increases. When energy expenditure is less than energy intake, the body stores the fat and increases the fat ratio. When the energy expenditure is higher than the energy intake, the body is burned and the fat rate is reduced. Oils are the most energy-giving nutrient. Some of the vitamins can be taken with body fat. Fats give a sense of saturation because they slowly leave the pussy Subcutaneous fat tissue prevents rapid loss of body heat. Oils are necessary for the production of some hormones and hormone-like items that take part in the regular functioning of the body.
