Tomatoes are a popular vegetable that is grown in almost every plot. Excellent taste gives the dish a unique flavor, whether it is a fresh tomato or canned in its own juice. However, the true value lies in the composition, rich in minerals and trace elements useful for the body. Let's talk in this article about the benefits and dangers of this homemade vegetable, analyze the structure of its roots and learn how to properly store vegetables in an apartment.
The tomato belongs to the nightshade family. The root system of the plant is well branched; in the process of shoot development, it is formed by active growth of lateral processes. It is better to plant roots in the ground to a depth of 30-50 cm.
At the stage of seed germination, a root (germinal) is formed in the soil, which later becomes the main root of the tomato. Already in the second week, it is overgrown with branches. A little later, the adventitious branches of the root system grow. They are formed directly from the stem, in some plants directly from the leaves.
The most extreme parts of the root system are thin hairs (down). It is through them that the culture receives moisture and nutrients from the soil. It is not for nothing that these areas are called the suction zone.
Gardeners, when removing a bush from a garden bed, probably noted that the parameters and structure of the roots are different. This is due to the belonging of the plant to a certain type. There are only two of them: fibrous and pivotal. The fibrous root does not have a pronounced main rhizome; it looks like a loofah (hence the name). In contrast, the core type is characterized by a well-developed elongated root, which differs significantly in parameters from other branches. Its length is greater than the previous type.
When planting seedlings, it should be borne in mind that the damaged root stops vertical growth. After engraftment in a new place, the root system is formed by building up lateral processes. To stimulate the development of the root part of the plant, it is recommended to spud the bushes.
The composition of tomatoes contains many micro and macroelements, vitamins useful for the body. Among the main ones:
The fruits contain a large amount of dietary fiber, organic acids, which improve the functioning of the gastrointestinal tract. The flavonoid quercetin cleans and strengthens blood vessels, which has a beneficial effect on the functioning of the vascular system. Tomato contains a unique substance called lycopene, which lowers the risk of cancer.
Tomato is included in the diet due to its low calorie content (per 100 gr. 21 Kcal). There is little fat in it, and the available carbohydrates are easily absorbed by the body. The low sugar content allows the use of the vegetable for patients with diabetes mellitus.
Nutritionists and doctors confirm the positive effect of tomatoes on the human body. First of all, the fruits improve the structure of the blood, which has a beneficial effect on the work of individual organs and all vital systems. The thinning effect prevents blood clots. And the organic acids included in the composition improve digestion, which makes it easier to assimilate heavy foods (for example, meat).
Given the composition rich in valuable substances, we can state the following usefulness of tomatoes for the human body:
If we consider the usefulness of the product specifically for men, then the following advantages of its use stand out:
Tomatoes are equally valuable for women. Folic acid in the composition plays an important role in the functioning of female organs. Its main feature is the regulation of fertility. Therefore, tomatoes must be included in the menu for those who want to become a mother, as well as during pregnancy. On the basis of a red vegetable in cosmetology, there are many products, the action of which is aimed at rejuvenating the skin, feeding it with useful microelements. It is worth emphasizing the low calorie content of the product, which makes it possible to include the fruits in the diet. This is important to preserve beautiful body shapes.
For children, tomatoes are also of great value, which is due to their rich chemical composition. Valuable micro and macro elements take an active part in the intensive growth of the child. The main benefits of eating tomatoes are:
An interesting fact is that tomatoes retain their valuable properties even after processing. Therefore, in addition to fresh vegetables, it is useful to use tomato juice, various sauces and dried preparations.
In addition to nutrients, tomatoes contain organic acids that can exacerbate chronic diseases. Therefore, this is the main contraindication for their use.
So, for example, oxalic acid negatively affects water-salt metabolism, which causes disruption of the kidneys. It activates the digestive system, resulting in increased bile production. In the presence of gallstone disease, this effect provokes a deterioration in health.
You cannot eat tomatoes if you have:
Heavy smokers should not get carried away with eating fresh fruits, as tomatoes increase nicotine addiction. Of course, it is preferable to give up cigarettes in favor of tomatoes, but everyone should make this choice independently.
Allergy sufferers should also exclude tomato products from the diet. Tomato is a strong allergen, in addition, purchased fruits can accumulate toxic substances that are part of various preparations for processing plants.
Eating a vegetable of unknown origin for vulnerable people is like playing Russian roulette. You should not conduct such experiments with your health.
Ripe tomato acquires extraordinary flavoring notes due to the combination of sugars and acids with volatile substances. It is the volatile components that are extremely susceptible to low temperatures. This explains the fact that the taste of the vegetable is lost after storage in the refrigerator.
But where, then, should you keep vegetables and what temperature regime should you choose for them? The issue of storing tomato fruits without losing taste has been solved for a long time by French scientists, until they confirmed empirically that the refrigerator is not a panacea. Temperature + 20 ° С not only ensures the safety of volatile substances, but also contributes to their intensive production. However, such a regime is not suitable for long-term crop conservation.
There are several simple rules, the observance of which will make it possible to enjoy the taste of fresh tomatoes until winter, or even more.
The usefulness of tomatoes is obvious, but it is worth eating only high-quality fruits without signs of deformation and disease. To do this, you need to provide proper conditions for storing the crop.

The fruits contain vitamins C, PP and AA. Tomatoes contain the most useful micro and macro elements for humans: iron, potassium, zinc, magnesium, thiamine, calcium and others. Fruits are rich in organic acids, dietary fiber, flavonoids, and even lycopene, which prevents cancer.
In nature, there are no substances that are uniquely useful or only harmful. In most cases, it all depends on the amount consumed. We can talk about direct benefits in the context of reasoning about the natural sugar contained in berries, fruits and cereals. A commercially available monosaccharide is similar to edible sugar. The beneficial properties appear with moderate consumption.
And yet fructose has some features that distinguish it favorably from glucose:
Fructose has a beneficial effect on the body when:
In some ways, yellow tomatoes are much healthier than red ones:
Yellow tomatoes contain less vitamin C, but this can be considered an advantage. An excess of this vitamin can cause heartburn, so yellow tomatoes are less aggressive on the body.
Yes, tomatoes of various varieties contain a huge number of useful substances, but they can also negatively affect the functioning of the body's systems. Especially if you neglect the recommended "doses" for their use. Let's see who it is harmful to eat tomatoes and why.
