It is a name given to a diet based on carbohydrates or protein, which is applied for various reasons, especially to lose weight. However, this type of nutrition is a form of nutrition that poses a risk to health, since it does not meet the general nutritional needs of our body. The balance of vitamins and minerals to be taken from food is extremely important for the body to carry out all biochemical mechanisms in balance. However, contrary to this need, preferring a single type of diet causes the body to be stressed and to experience water and muscle loss instead of fat loss. For this reason, the table that is reflected on the scale in the first place, as if losing weight, is taken back in a short time, leading to an unhealthy situation. In case of deficient intake of protein, which is one of the main food sources of the body, a weakening of the metabolism and accompanying deterioration of the body's balance will occur. Carbohydrates are the main food group that is generally disregarded in a uniform diet. Although carbohydrates are seen as a food group that poses a danger in weight gain, they constitute a very important food group in terms of energy needs. Long-term deficient nutrition in terms of carbohydrates will lead to the development of thyroid diseases in the future. A single type of nutrition model made in terms of vegetables or fruits will cause different health problems such as anemia and hormone imbalances. If all the food groups we take in the diet are not balanced, deterioration in liver enzymes and dysfunctions will occur by tiring the kidneys. It will never be possible to lose weight quickly with a single type of nutrition method, and it will weaken the immune system, as it will cause deterioration in the balance of the immune system. The healthy fats we take with the diet, the lycopene in their content, tomatoes and tomato products with high antioxidant levels, daily consumption of fruits and vegetables will also be extremely protective against various diseases. Dietary intake of fish rich in omega-3 fatty acids will also have a protective effect on both general health and skin health. Inclusion of black and green tea consumption in the menu in a controlled manner will be supportive in terms of benefiting from its antioxidant properties. As a general nutritional approach, avoiding sugar and sugar-containing foods and beverages, pastries including bread, foods with high glycemic index, all kinds of processed foods, canned products, margarine, heat-treated oils, corn, rice, potatoes, instant soups, sauces and Not including mayonnaise in your menus will provide a supportive effect on your general health. Remember, when you act in a balanced way with the rainbow principle in your diet and when you do your physical activities by considering the needs of your body, health will be with you. I wish you to always remember that protecting your health is a process where multiple factors must be in balance. Stay healthy.
