Healthy nutrition: the key to longevity

Healthy nutrition: the key to longevity

Section 1: Fundamental principles of healthy diet

Healthy diet is not just a diet, it is a way of life that determines our physical and mental well -being, as well as the life expectancy. The basis of a healthy diet is a balanced diet that provides the body with all the necessary nutrients: proteins, fats, carbohydrates, vitamins, minerals and water. The key factor is the variety of products, since no product contains all the necessary substances in the optimal ratio. The principles of a healthy diet are applicable to people of all ages, but require adjustments depending on individual needs, level of activity, state of health and genetic predisposition.

1.1 Macronutrients: proteins, fats and carbohydrates

Squirrels, fats and carbohydrates are macronutrients that provide the body with energy and building materials. Their correct ratio in the diet is critical of health.

• Squirrels: Squirrels are building blocks of our body. They are necessary for the growth and restoration of tissues, the production of enzymes and hormones, as well as maintaining the immune system. The recommended protein consumption rate is 0.8 grams per kilogram of body weight for adults leading a sedentary lifestyle. For athletes and people involved in physical labor, the need for protein increases to 1.2-1.7 grams per kilogram of body weight. Sources of protein: meat, poultry, fish, eggs, dairy products, legumes, nuts and seeds. It is important to choose low -fat sources of protein, such as chicken breast without skin, low -fat fish and legumes.

• Fat: Fats are necessary to maintain cell health, the production of hormones and the assimilation of fat -soluble vitamins (A, D, E and K). However, not all fats are equally useful. Unsaturated fats (monoen -saturated and polyunsaturated) are useful for the health of the heart and blood vessels. They are found in olive oil, avocados, nuts, seeds and fatty fish (salmon, tuna, mackerel). Saturated fats contained in red meat, fatty dairy products and coconut oil should be consumed moderately. Transfiners contained in processed food products, such as baking and fast food, should be avoided because they increase the level of “poor” cholesterol (LDL) and reduce the level of “good” cholesterol (HDL), increasing the risk of cardiovascular diseases.

• Carbohydrates: Carbohydrates are the main source of energy for the body. There are complex carbohydrates and simple carbohydrates. Complex carbohydrates contained in whole grain products, vegetables and fruits are digested more slowly and provide the body with energy for a longer period. Simple carbohydrates contained in sugar, sweets and white flour are digested quickly and cause a sharp jump in blood sugar, followed by a sharp fall. It is recommended to give preference to complex carbohydrates and limit the consumption of simple carbohydrates. Fiber contained in whole grain products, vegetables and fruits is a type of complex carbohydrates, which is not digested by the body, but is necessary for the health of the digestive system.

1.2 micronutrients: vitamins and minerals

Vitamins and minerals are micronutrients necessary for the normal functioning of the body. They participate in many biochemical processes, support the immune system and protect the cells from damage. The lack of vitamins and minerals can lead to various diseases.

• Vitamins: Vitamins are divided into fat -soluble (A, D, E and K) and water -soluble (B vitamins and vitamin C). Fat -soluble vitamins accumulate in the body, so their excessive consumption can be toxic. Water -soluble vitamins do not accumulate in the body and are excreted in the urine, so they must be regularly replenished. Different vitamins are found in various products, so it is important to eat a variety of foods.

• Minerals: Minerals, such as calcium, iron, potassium, magnesium and zinc, are necessary for the health of bones, blood, nervous system and other organs and systems. Calcium is important for the health of bones and teeth. Iron is necessary for the production of hemoglobin, which suffers oxygen in the blood. Potassium is important for the regulation of blood pressure. Magnesium is necessary for the functioning of muscles and the nervous system. Zinc is necessary for the immune system and wound healing.

1.3 Water: the basis of life

Water is necessary for all vital processes in the body. It is involved in the transportation of nutrients, regulation of body temperature, remove waste and lubrication of joints. It is recommended to drink at least 8 glasses of water per day. The need for water can increase with physical activity, in hot weather and in certain diseases. Other liquids, such as tea, coffee and juices, can also contribute to fluid consumption, but pure water is the best choice.

Section 2: The effect of a healthy diet on longevity

Healthy nutrition has a deep effect on the duration and quality of life. It helps to prevent the development of chronic diseases, such as cardiovascular diseases, type 2 diabetes, cancer and Alzheimer’s disease, which are the main causes of mortality around the world.

2.1 Prevention of cardiovascular diseases

Healthy nutrition plays a key role in the prevention of cardiovascular diseases. A low content of saturated fats, trans fats and cholesterol helps to reduce the level of “poor” cholesterol (LDL) and increase the level of “good” cholesterol (HDL), thereby reducing the risk of the formation of atherosclerotic plaques in the arteries. The use of a large amount of fruits, vegetables and whole grains rich in fiber helps to reduce blood pressure and maintain healthy weight, which also contributes to the health of the heart and blood vessels. The restriction of salt consumption helps to reduce blood pressure and the risk of hypertension.

2.2 Prevention of type 2 diabetes

Healthy nutrition is a cornerstone in type 2 diabetes prevention. Diet with a low content of simple carbohydrates and a high content of complex carbohydrates, fiber and proteins helps maintain a stable blood sugar and prevents the development of insulin resistance. Weight control also plays an important role in the prevention of type 2 diabetes, since overweight increases the risk of developing this disease. Regular physical exercises combined with healthy nutrition help to improve insulin sensitivity and reduce the risk of type 2 diabetes.

2.3 Reduction of risk of cancer

Healthy diet can reduce the risk of developing some types of cancer. The use of a large number of fruits, vegetables and whole grains rich in antioxidants helps to protect cells from damage caused by free radicals that can lead to cancer. Limiting the consumption of red and processed meat can reduce the risk of developing colon cancer. Maintaining healthy weight also plays an important role in cancer prevention, since overweight increases the risk of developing certain types of cancer.

2.4 Slow down cognitive decline

Healthy nutrition can help slow down a cognitive decline and reduce the risk of developing Alzheimer’s disease and other forms of dementia. Diet, rich in omega-3 fatty acids, antioxidants and vitamins of group B, can improve the function of the brain and protect it from damage. The Mediterranean diet, characterized by high consumption of olive oil, fish, fruits, vegetables and whole grains, is associated with a lower risk of developing cognitive impairment.

2.5 maintenance of healthy weight

Healthy nutrition is an important factor in maintaining a healthy weight. A low calorie diet, saturated fats and sugar, combined with regular physical exercises, helps to burn more calories than consumed, which leads to weight loss. Maintaining healthy weight reduces the risk of developing many chronic diseases, including cardiovascular diseases, type 2 diabetes, some types of cancer and osteoarthritis.
