Nutrition for health and longevity: the path to active and long life
Chapter 1: Fundamentals of a healthy diet: key principles and components
Healthy nutrition is the cornerstone of good health and longevity. This is not just a diet or a temporary restriction, but a lifestyle that provides the body with all the necessary nutrients for optimal functioning. The fundamental principles of a healthy diet are in balance, diversity and moderation.
1.1 Balance of macronutrients: proteins, fats and carbohydrates
Macronutrients are the main building blocks of our power that provide us with energy and are necessary to maintain vital activity. Their correct ratio is critical.
-
Squirrels: It is necessary for the construction and restoration of tissues, the synthesis of enzymes and hormones, as well as maintaining the immune system. Sources: meat, poultry, fish, eggs, legumes, tofu, nuts and seeds. The recommended share in the diet: 10-35% of the total number of calories, depending on the age, level of activity and health status. For example, for a person leading a sedentary lifestyle, 0.8 g of protein per kg of body weight is enough, and for an athlete-1.2-2.0 g.
-
Fat: Important for the energy reserve, the assimilation of fat -soluble vitamins (A, D, E, K), the synthesis of hormones and maintaining the health of cell membranes. Sources: avocados, nuts, seeds, olive oil, fatty fish (salmon, sardins, macrel). It is important to give preference to unsaturated fats (mono-polyunsized), which are useful for the health of the heart and blood vessels, and limit the consumption of saturated fats (contained in red meat, butter, coconut oil) and transfiners (contained in processed products and fast food). Recommended share in the diet: 20-35% of the total number of calories.
-
Carbohydrates: The main source of energy for the body. Sources: fruits, vegetables, cereals, legumes. It is important to choose complex carbohydrates (whole grains, vegetables, fruits) that slowly release energy and maintain a stable blood sugar level, instead of simple carbohydrates (sweets, white bread, carbonated drinks), which quickly increase blood sugar and can lead to a sharp fall. Recommended share in the diet: 45-65% of the total number of calories.
1.2 micronutrients: vitamins and minerals
Micronutrients, although necessary in small quantities, play a key role in maintaining health and preventing diseases.
-
Vitamins: Organic compounds necessary for various metabolic processes. For example, vitamin C strengthens immunity, vitamin D is necessary for bone health, vitamin E – antioxidant, group B vitamins are involved in energy metabolism.
-
Minerals: Inorganic substances necessary for various functions of the body. For example, calcium is necessary for the health of bones, iron – for the transfer of oxygen, potassium – to maintain blood pressure, zinc – for immunity.
You can get enough vitamins and minerals from a variety of diet, including fruits, vegetables, whole grain products, legumes, nuts and seeds. In some cases, it may be appropriate to take vitamin-mineral complexes, but only after consulting a doctor.
1.3 Water: Life liquid
Water is an indispensable component of a healthy diet, necessary for all vital processes in the body. It is involved in thermoregulation, transportation of nutrients, waste removal, maintaining joint health and many other functions. It is recommended to drink at least 1.5-2 liters of water per day. In addition to pure water, you can use herbal teas, fruit and vegetable juices, unsweetened drinks.
1.4 fiber: food for intestines
Fiber is undigested fibers contained in plant products. It is important for the health of the digestive system, maintaining the normal level of cholesterol and blood sugar, and also contributes to a feeling of satiety. Sources: fruits, vegetables, whole grain products, legumes, nuts and seeds. Recommended daily norm is 25-35 grams.
1.5 antioxidants: protection against free radicals
Antioxidants are substances that protect cells from damage to free radicals, unstable molecules that can contribute to the development of various diseases, including heart cancer and disease. Sources: fruits, vegetables, berries, nuts, seeds, green tea. Especially rich in antioxidants are products of bright colors (for example, blueberries, broccoli, red pepper).
Chapter 2: Meals for longevity: Scientific research and diets
Modern scientific research confirms that nutrition plays a key role in the duration and quality of life. There are various diets and nutrition strategies that have proven their effectiveness in terms of prolonging life and prevention of age -related diseases.
2.1 Mediterranean diet:
One of the most studied and recommended diets for health and longevity. Basic principles:
- The abundance of vegetables and fruits: at least 5 servings per day.
- Whole grain products: bread, pasta, Fig.
- Legumes: beans, lentils, chickpeas.
- Nuts and seeds: almonds, walnuts, flax seeds.
- Olive oil: the main source of fat.
- Fish and seafood: several times a week.
- Moderate consumption of dairy products: cheese, yogurt.
- Limited red meat consumption: several times a month.
- Moderate wine consumption: red wine in small quantities (1-2 glasses per day) during meals.
The Mediterranean diet is rich in antioxidants, useful fats and fiber, which helps to reduce the risk of cardiovascular diseases, diabetes, cancer and neurodegenerative diseases.
2.2 Okinawa diet:
The traditional diet of the inhabitants of the Japanese island of Okinava, known for their high life expectancy. Basic principles:
- Low calorie content: moderate calorie intake.
- The abundance of vegetables: especially the battal (sweet potatoes).
- Tofu and other soy products.
- A small amount of fish.
- Limited consumption of meat and dairy products.
The Okinawa diet is rich in antioxidants and nutrients, but low in the content of calories and fats, which helps to maintain a healthy weight and reduce the risk of age -related diseases.
2.3 Dieta Mind:
A diet designed specifically to maintain brain health and reduce the risk of developing Alzheimer’s disease. Basic principles:
- The abundance of sheet green vegetables: at least 6 servings per week.
- Berries: at least 2 servings per week.

2.4 Publicities:
A diet excluding meat, but including fish and seafood. Allows you to get a sufficient amount of protein and omega-3 fatty acids necessary for the health of the heart and brain.
2.5 interval fasting:
Not a diet in the classical sense, but a diet, which involves the alternation of periods of eating and starvation. The most popular options:
- 16/8: 16 hours of starvation and 8 hours of eating.
- 5: 2: 5 days of regular power and 2 days with calories restriction (about 500-600 calories).
Interval fasting can help reduce weight, improve insulin sensitivity and reduce the risk of developing certain diseases. However, before the start of interval starvation, it is necessary to consult a doctor.
2.6 Calorian restriction:
Scientific studies show that moderate calorie restriction (10-30% of the usual norm) can extend life and improve health. However, it is important to prevent a deficiency of the necessary nutrients.
