The benefits and harms of tomatoes for the human body

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 structure of the roots and root system of tomatoes

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.

Chemical composition

The composition of tomatoes contains many micro and macroelements, vitamins useful for the body. Among the main ones:

  • potassium;
  • magnesium;
  • calcium;
  • iodine;
  • iron;
  • zinc;
  • thiamine;
  • riboflavin;
  • beta carotene;
  • vitamins PP, A, C, etc.

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.

The benefits and harms of consumption for the body of a woman and a man

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:

  • the product has anti-sclerotic and anti-rheumatic effects;
  • thanks to potassium, iron and magnesium, the work of the heart muscle improves;
  • alpha-tomatin is a natural oncoprotector, which is expressed in the ability to destroy cancer cells;
  • iron prevents the development of anemia, helps to restore the blood structure after a previous illness.

If we consider the usefulness of the product specifically for men, then the following advantages of its use stand out:

  • prevention of prostate cancer, sexual impotence;
  • reduction of the inflammatory process in prostatitis;
  • cleansing the liver in the treatment of alcohol addiction.

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:

  • strengthening the immune system;
  • enrichment of blood with nutrients;
  • cleansing the liver of toxins;
  • improving metabolism in the body;
  • prevents the development of anemia.

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.

Contraindications for eating tomatoes

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:

  • disorders of the musculoskeletal system (acids cause severe pain in the joints);
  • problems with the gastrointestinal tract;
  • hypertension (limit the use of salted and pickled fruits);
  • pancreatitis.

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.

How to store tomatoes at home in an apartment?

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.

  1. The main key to unraveling the question lies in the correct selection of the variety. These should be crops of late and mid-late ripening. Of the cultivation methods, preference is given to open ground. Greenhouse tomatoes do not have a long shelf life. Recommended varieties: New Year's, Red Stone (the vegetable remains firm and tasty until winter), Long Keeper, Giraffe (keeps fresh until spring!). Slightly less (6-8 weeks) are stored: Pharaoh, Viscount, Paladin. Not suitable for long-term storage of plants with an early and medium-early ripening period.
  2. The storage location can be any cool dark rooms (basements, cellars, pantries, vegetable compartment of the refrigerator).
  3. The fruits retain their freshness and valuable qualities at a temperature of 8-10 ° C, air humidity - within 80%.
  4. Proper preparation of tomatoes is considered an important point in storage. They need to be sorted by removing damaged, deformed, overripe and green specimens. Milk-ripened vegetables are ideal for long-term storage. To clean tomatoes from harmful microbes, it is recommended to wipe each with a cotton pad dipped in alcohol (vodka).
  5. You can put the fruits in wooden or plastic boxes, which should have openings for air access. The bottom and walls of the container are covered with paper, after which the tomatoes are laid out one by one with the stalks up. Each layer must be covered with paper. In total, 3 layers are formed in the box. The top is covered with sawdust. You can also wrap each vegetable in black paper when stacking. This will prevent the spread of rot if one of the tomatoes is damaged. With this method, the safety of the crop is guaranteed by the New Year holidays. If varieties with a long shelf life are used, you can enjoy a delicious tomato until spring. In the refrigerator, the fruits can spend no more than 7-8 days.

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 benefits and harms of tomatoes for the body. With diabetes. Danger of green tomatoes

The tomato is a popular food staple found on the tables of almost every family. Red, pink, yellow and even black fruits are easy to grow on your own plot or even on your balcony. The popularity of tomatoes is due to their taste and rich list of useful elements.

The cultivated plant belongs to the nightshade family, the fruits of which, contrary to popular belief, are berries. They are often called tomatoes. And the very name of the tomato is translated from Italian as "golden apple".

The homeland of the vegetable is considered to be South America, where it grew in the wild. It came to Russia at the beginning of the 18th century in the form of an ornamental plant. Nowadays, people use it in cooking - they eat it raw, pickle it, add it to salads and hot dishes.

Composition and calorie content

There are very few calories in tomatoes - 21. They contain little fat, and the available carbohydrates are easily absorbed by the human body.

Tomatoes are low in sugar, so they can be consumed even if you have diabetes.

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.

Conditional benefit

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:

  • Low glycemic index... After consumption, there are no sudden surges in blood sugar. The property is explained by the fact that insulin is practically not required for splitting. The pancreas is significantly unloaded, the body receives energy gradually.
  • The calorie content is similar to sugar, but at the same time it is twice as sweet... This advantage allows you to reduce the energy value of products.
  • Due to the prolonged consumption of energy after consuming a monosaccharide, a person gets less tired from physical exertion and recovers quickly.
  • One of the few sugars that does not have the side effect of an allergic reaction.
  • Retains moisture and product color, is a natural preservative.
  • when eaten, the processes of fermentation and gas formation in the intestine are less pronounced than when using ordinary sugar.
  • Decreases the level of caries formation, dental plaque, inflammatory processes in the oral cavity. These properties are more characteristic of natural fructose.
  • Quickly cleanses the body in case of alcohol poisoning, converting alcohol into harmless decomposition products.

Fructose has a beneficial effect on the body when:

  1. Used in moderationnot exceeding 40 grams in pure form. This is 5 bananas or 3 apples.
  2. Consumed in the form of fruits and vegetables that contain fiber... Vegetable fibers provide a slow and even breakdown of sugar.

Which tomatoes are healthier: red or yellow

In some ways, yellow tomatoes are much healthier than red ones:

  1. They contain retinol, which is beneficial for vision, bones, and skin.
  2. Yellow tomatoes rarely provoke an allergic reaction.
  3. This tomato variety contains fewer calories.
  4. Yellow tomatoes contain more myocin, a substance that strengthens the walls of blood vessels.

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.

The harm of tomatoes to 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.

Diseases of the digestive tract

If a person has any problems with the organs of the gastrointestinal tract (and especially if pathological abnormalities are observed), then eating tomatoes, he can seriously harm his body.

With disorders of the gastrointestinal tract, accompanied by high acidity, vegetables of the Solanaceae family should not be eaten at all, in any form. Also, tomatoes are contraindicated for kidney damage of a different nature.

Important! If you have a neglected ulcer, exacerbation of gastritis or problems with the pancreas (pancreatitis), then excessive consumption of tomatoes can have an extremely negative effect on the functioning of the affected organs. Therefore, they need to be seriously limited in their diet..

Allergic reactions

Since tomatoes are red, they are classified as foods that increase the risk of developing any allergic reactions. Therefore, the amount of consumed tomatoes must be controlled:

  1. Pregnant
  2. For children
  3. All allergy sufferers.

High level of uric acidity

If the diagnosis is high uric acidity, then tomatoes can also be harmful to health.And all because an increase in uric acidity provokes arthritis or polyarthritis and it is impossible to determine exactly how tomato juice will affect the course of these diseases.
