Nutrition and health: 50% success in your hands.
Chapter 1: Health foundation – food.
Food is not just a process of eating, it is a cornerstone of health, which has a direct effect on the physical and mental state of a person. It is a source of energy, building materials for cells and tissues, as well as a regulator of metabolic processes. Neglect of the principles of a healthy diet can lead to a number of diseases, a decrease in immunity and a deterioration in the quality of life. Proper nutrition, on the contrary, contributes to the maintenance of optimal weight, strengthening bones, improving the brain, reducing the risk of developing chronic diseases and increasing general vital energy.
1.1 Macronutrients: proteins, fats and carbohydrates.
The basis of the diet are macronutrients: proteins, fats and carbohydrates. Each of them performs its specific functions and is necessary for the normal functioning of the body.
-
Proteins (proteins): The building material of the body. They participate in the construction and restoration of tissues, synthesis of enzymes, hormones and antibodies. Proteins consist of amino acids, some of which are indispensable and should enter the body with food. Recommended protein consumption varies depending on age, gender, level of physical activity and health. Sources of protein: meat, fish, poultry, eggs, dairy products, legumes, nuts and seeds. It is important to give preference to low -fat sources of protein, such as chicken breast without skin, fish, tofu and lentils. An excess of protein is also undesirable, as it can lead to renal overload and other problems.
-
Fat (lipids): The energy source necessary for the assimilation of fat -soluble vitamins (a, d, e, k), the synthesis of hormones and maintaining cell health. Fat are divided into saturated, unsaturated and transfigure. Saturated fats contained mainly in animal products (fatty meat, butter, cheese) should be consumed moderately, since their excess can increase the level of cholesterol in the blood. Unsaturated fats contained in vegetable oils (olive, avocados, sunflower), nuts, seeds and fatty fish (salmon, tuna, mackerel) are considered healthy. Transfiners contained mainly in processed products (fast food, pastries, margarine) should be avoided, since they negatively affect the cardiovascular system. It is important to observe the balance in fat consumption and give preference to unsaturated fats.
-
Carbohydrates: The main source of energy for the body. They are divided into simple (sugar) and complex (starch, fiber). Simple carbohydrates are quickly absorbed and cause a sharp jump in blood sugar, so their consumption should be limited. Complex carbohydrates are absorbed more slowly and provide the body with energy for a longer period of time. It is recommended to use complex carbohydrates contained in whole grain products (bread, cereals), vegetables and fruits. Fiber, a variety of complex carbohydrates, is not digested in the body, but plays an important role in maintaining the health of the digestive system. It contributes to the normalization of the stool, a decrease in blood cholesterol and control of blood sugar.
1.2 micronutrians: vitamins and minerals.
Vitamins and minerals are micronutrients necessary for the normal functioning of the body. They participate in the regulation of metabolic processes, strengthening immunity, maintaining the health of bones, skin and hair.
-
Vitamins: Organic compounds necessary for many biochemical processes in the body. They are divided into fat -soluble (a, d, e, k) and water -soluble (vitamins of group B, vitamin C). Each vitamin performs its specific functions, and their deficiency can lead to various diseases. Sources of vitamins: fruits, vegetables, berries, greens, meat, fish, dairy products and whole grain products.
-
Minerals: Inorganic substances necessary to maintain the health of bones, teeth, blood, nervous system and other organs and systems. The main minerals include calcium, iron, potassium, magnesium, zinc, iodine and selenium. Sources of minerals: fruits, vegetables, greens, nuts, seeds, meat, fish, dairy products and whole grain products.
It is important to get a sufficient amount of vitamins and minerals with food. In some cases, vitamin-mineral complexes may be required, but before that it is necessary to consult a doctor.
1.3 Water: Elixir of Life.
Water is an Essential Nutrew, vital for all processes in the body. It accounts for about 60% of the body weight and is involved in the regulation of body temperature, the transportation of nutrients and oxygen, the removal of waste and maintaining skin health. It is recommended to drink at least 2 liters of water per day. The need for water can increase with physical activity, in hot weather and in some diseases. Sources of water: pure water, fruits, vegetables, soups and other liquids.
