Vegetables are the most valuable food. The irreplaceability of vegetables in the diet is determined by the fact that they are the main suppliers of carbohydrates, vitamins, mineral salts, phytoncides, essential oils and dietary fibers necessary for the normal functioning of the body.
Plant food is a high-energy product. In the process of photosynthesis, plants accumulate solar energy and, carrying out a number of chemical transformations, produce adenosine triphosphate (ATP), which is used for the synthesis of their proteins, carbohydrates, and fats, putting some of them in reserve. In the human body, there is a reverse process of disintegration of the energy bonds of plant food, thanks to which carbohydrates, proteins, and fats that are already specific to humans are formed.
Vegetables are not only essential foods that support human vitality, but also an effective remedy recognized by folk and scientific medicine. The nutritional value and medicinal properties of vegetables are due to the presence of various chemical substances in their composition and structure, which have a wide pharmacological spectrum of action on the body and give dishes an original taste and aroma.
Vegetable food has a predominantly alkaline reaction, and its presence in the diet establishes an optimal acid-base balance in the human body.

Maxims about the benefits of fruits and vegetables have long been "commonplace". Everyone talks about this, but few people think about why they are actually useful, and what benefits this or that vegetable brings to the body. Let's find out more about which vegetables and what to eat, and find out which are most useful for humans.
The need for vegetables and fruits
What is there in vegetables that cannot be obtained from other types of food?
First, these are vitamins. Vitamins are amino acids necessary for the normal functioning of the human body. Some of them the body can synthesize itself, but most must be obtained from outside with food. About half of the known number of vitamins is found mainly in plant foods – for example, vitamin C (ascorbic acid) or vitamin A (retinol). Therefore, fruits and vegetables are primarily an essential source of vitamins.
Secondly, micro-and macronutrients. Vegetables and fruits contain a lot of useful and necessary minerals: iron for blood formation, potassium for the work of blood vessels and the heart, calcium and phosphorus for the "construction" of bones and teeth, and many others. At the same time, they are often digested better than from animal products.
Third – fiber, coarse dietary fiber, which itself has no energy value and is not digested. However, they do a very important job-clean the intestines and improve its peristalsis, contributing to normal digestion. Without fiber, normal digestion is impossible. In products of animal origin, these fibers are not contained at all – they can only be obtained from plants: vegetables and fruits, as well as cereals.
The first place is deservedly taken by the tomato. This vegetable is a real storehouse of vitamins and minerals. They contain a large amount of lycopene (a substance that gives tomatoes a red color) is a strong antioxidant, protects the DNA, preventing the development of tumors, slows down the development of atherosclerosis, protects the lens of the eye, preventing the development of cataracts. Tomatoes also contain a lot of potassium-an element necessary for the normal functioning of the heart and blood vessels.
Carrots are another vegetable that can be called a must-eat. Many people know that carrots are very useful for the eyes. This is true, carrots contain a lot of vitamin A, which is part of the eye pigment rhodopsin, responsible for the perception of light and twilight vision. In addition, vitamin A is an excellent antioxidant.
Pumpkin. The benefits of this vegetable can hardly be overestimated. Pumpkin is famous for the highest content of beta-carotene among vegetables and fruits, which, in addition, is almost completely absorbed by the body. Pumpkin improves the work of the intestines, helps to clear the liver, improves immunity due to the high content of vitamin C. in addition, pumpkin is very nutritious and not too high in calories, and is great for the diet table.
olgar pepper. This vegetable is recommended for daily use also due to its high content of vitamin C. in addition, pepper contains a number of b vitamins that have a beneficial effect on metabolism and the state of the nervous system. Red bell peppers, like tomatoes, contain a lot of the pigment lycopene, which has strong antioxidant properties.
