Is a tomato a berry or a vegetable?
The fruits of tomatoes, so beloved by all gardeners without exception, have been causing heated debate over the years regarding their belonging to plant species. The reason for this is the difference in definitions and classification of edible crops among botanists and culinary specialists.
The botanical scientific literature classifies tomatoes exclusively as berries. The arguments in favor of this definition are the following:
- fruit growth on bushes;
- the form;
- thin skin with juicy pulp;
- an abundance of small seeds, which, after ripening, fall to the ground and give new shoots.
Seeds in fruits and the method of reproduction of tomatoes in the wild serve as the main argument, because according to this principle, all berries reproduce without exception. For the same reason, watermelon is also considered a berry.
However, here the culinary community enters into an argument with the scientific community. The unwritten rules for the classification of vegetables, fruits and berries, adopted several centuries ago, did not appear out of nowhere. The answer to this question lies in history.
History reference
South America is considered the birthplace of tomatoes. The opinions of researchers differ on this issue, but it is known for certain that tomatoes came to Europe thanks to European conquering seafarers. It was they who brought to the continent an unprecedented plant with red berries, which the Indians called "tomatl".
For a long time, Europeans were suspicious of outlandish red fruits, but considered them extremely beautiful.Tomato bushes began to be grown in greenhouse tubs, on balconies, in open flower beds. Fortunately, the climate of Portugal, Spain, Italy allowed tomatoes to grow in all their glory, without requiring special care.
Until the beginning of the 19th century, tomatoes were considered a poisonous plant and were not eaten.
In the Russian Empire, the first written evidence of tomatoes appears during the time of Catherine II. Sources say that European ambassadors, among other gifts and dishes, brought unusual fruits of bright red color to the Empress. According to other sources, tomato crops were grown earlier in the southern regions of the empire - in the Crimea and the Caucasus.
What family does it belong to?
From a botanical point of view, the tomato occupies a certain place in the classification of plants. In order to understand the question of whether tomatoes belong to berries or vegetables, it would be useful to familiarize yourself with the scientific definitions of a tomato.
So, having opened any encyclopedia of plants, you can find out that the tomato is a herbaceous plant of the nightshade genus. It includes more than a hundred small genera of plants and a little less than three thousand species. Solanaceae are represented by herbs, shrubs, small trees. Nightshade fruits are shaped either as berries or capsules. Some fruits (berries) of nightshade people actively use for food: tomatoes, potatoes, eggplants. Tobacco, pepper, petunia, henbane ripen in the form of boxes.
Representatives of nightshade contain in their tissues a toxic substance - solanine. In tomatoes, it predominates in the stem and leaves of the plant. It was because of this substance that tomatoes were once considered inedible.
Characteristic
A tomato is a plant bush (from the ancient Aztec name "Tomatl").The fruit of a tomato is a berry, colloquially called "tomato" - in Italian, the phrase "pomo doro" means "golden apple".
The plant has a well-developed root system with a central taproot and a large number of small shoots. The diameter of the roots can reach 2.5 meters at a depth of up to 1 m. The stem is erect, in some liana-like varieties it can reach a height of 3-4 meters. The arrangement of the leaves is alternate, the flowers are of the correct form, the fruits are tied with tassels.
Tomato fruits are fleshy berries with small seeds. They may vary in color and size depending on the variety. The shape is round, teardrop-shaped or cylindrical. Weight varies from 50 g to 1 kg. Pigmentation of classic fruits includes the whole spectrum of red shades, yellow, white colors.
Among their analogues, tomatoes are classified according to the following criteria:
- bush growth type: determinant (undersized) and indeterminate (tall);
- ripening time: early, mid-season, late.
Growth features
Tomato is a heat-loving and light-loving crop that grows on open ground only in the southern regions, where hot summer turns into warm autumn and the velvet season. In cooler areas, tomatoes are successfully grown in closed greenhouses and greenhouses.
Favorable temperature for fruit ripening is 23-25 degrees. When the temperature drops, the bush slows down growth, and when the mark on the thermometer is below +10, it throws off the brushes and may die.
Tomatoes require not frequent, but plentiful watering under the root. High humidity and water droplets on the leaves lead to fungal diseases of the plant.The most common of these is late blight - a constant companion of tomatoes in cool regions with an insufficient number of sunny days.
The plant is sensitive to any additives to the soil, so fertilizers should be added carefully.
The main trace elements needed by the tomato are nitrogen, potassium and phosphorus.
Benefit and harm
The fruit of a tomato can be safely called a pantry of vitamins. Each tomato contains a whole complex of minerals at a fairly low calorie content. Tomatoes include fiber, vegetable protein, amino acids and enzymes that can break down and remove toxins from the body. Tomatoes are rich in vitamins A, B, C, trace elements of potassium, magnesium, sodium, calcium and iron.
The complex of useful substances of tomatoes includes:
- Lycopene - an antioxidant substance that slows down the aging process in the body. In cosmetology, tomato mass masks are used to combat mimic wrinkles, acne and inflammation of the skin. Lycopene also contributes to women's health, helps to overcome age-related changes.
- alpha tomatine - contributes to the prevention of cancer, slows down the growth of cancer cells. Cancer today is a little-studied disease that claims the lives of millions of people. Therefore, it will be useful for everyone to think about prevention, especially since tomatoes are a welcome treat on any table.
- Tyramine - has a beneficial effect on the thyroid gland, has the properties of serotonin - the "happiness hormone". For those who want to lose weight, this is a great alternative to a chocolate bar. Tyramine increases efficiency, activates thought processes, which can be used during study or work that requires serious concentration.
Tomatoes are recommended to be eaten not only as a preventive product, but also for certain diagnoses of serious diseases.
Substances contained in tomatoes improve intestinal motility, have a laxative effect, and help eliminate toxins from the liver. Indications for use: peptic ulcers, low intestinal patency, gastritis with low acidity.
Microelements of tomato contribute to the acceleration of metabolism, normalize metabolic processes and restore hormonal levels. Doctors recommend including tomatoes in the diet to prevent diabetes and thyroid diseases.
Regular use of the product contributes to the normalization of pressure, increases the elasticity of blood vessels, thins the blood, thereby significantly reducing the risk of blood clots. It is recommended to introduce it into the daily diet of all people suffering from atherosclerosis, angina, varicose veins.
Like any natural product with a significant supply of nutrients, tomatoes have contraindications. The human body is individual and in some cases, excessive consumption of tomatoes can cause significant harm.
First of all, it should be remembered that an excess of certain substances in the body can cause an allergic reaction. This is especially true for allergy sufferers suffering from the action of certain trace elements.
Do not get carried away with canned tomatoes. The marinade contains an increased amount of vinegar and salt, which, in interaction with the acids of tomatoes, can cause an exacerbation of gastric diseases.
People with genitourinary diseases are advised to exercise caution when consuming tomatoes.The oxalic acid contained in the tomato can provoke kidney exacerbations.
As noted above, tomatoes have a positive effect on the functioning of the gastrointestinal tract, but only in cases of normal functioning or with a low level of acidity.
Therefore, with peptic ulcers, pancreatitis, the acids contained in tomatoes can cause significant harm to health.
Interesting information
Despite all the scientific justification, it is generally accepted that tomatoes are vegetable crops and nothing else. And the reason for this is an amazing story that happened in the 19th century in America. Tomatoes, which had already settled on the European continent, returned to their historical homeland again as a sought-after edible crop. Mass trade in these fruits has acquired unprecedented proportions and even became the cause of a lawsuit.
The case concerned just a dispute about the classification of tomatoes. And the reason for it was very mercantile - vegetables at that time were subject to a higher customs duty than fruits. Therefore, the court ruled that tomatoes are considered vegetables. The arguments in favor of this decision were as follows:
- it is eaten with other vegetables, meat and fish dishes;
- tomatoes are an independent vegetable, and, unlike berries, are used in vegetable preparations and dishes not only as a sauce;
- tomato fruits do not have the inherent sweetness of berries, they are rarely used in dessert dishes and preparations with sugar.
These arguments subsequently turned out to be sufficient for the definition, albeit not scientific, that the tomato is a vegetable crop to be firmly entrenched in society.
