Over the history of existence, the benefits and harms of grapes have been thoroughly studied. Hundreds of volumes of scientific research in various areas have been written and a whole system of recommendations for its use for the consumer has been created.
The benefits of grapes: composition, application and unique properties
The incredible benefits of this berry are due to its unique biochemical composition, which has up to 300 components. This real storehouse of vitamins and microelements helps to increase the protective properties of the body, improve resistance to diseases and restore vitality.
It should be remembered that not only the pulp is useful in grapes. The peel and even the seeds contain a large amount of substances that have a strong therapeutic effect.
Scientific research has confirmed that grapes of different varieties and colors have different beneficial properties. They are more pronounced in dark berries than in light ones. Taste qualities and microelements and vitamins necessary for the body are also preserved in products prepared from these fruits: juices, wines, compotes and raisins.
Neither cosmetology, nor the food industry can do without this product. The essential oils contained in grape seeds serve as the basis for the preparation of a number of preparations for skin, hair and nails care. It is impossible to imagine confectionery without raisins and grape syrup.
The latest research confirms that the antioxidant pterostilbene in sour grapes can prevent diabetes. And lycopene, which is part of the peel of black berries, has a beneficial effect on libido, is a prophylactic agent and helps to treat male infertility.
Black grapes harm and benefits for men and women
There are more than 20,000 grape varieties in the world, with bunches of various shapes, sizes and colors. The variety of colors is explained by the presence of flavonoids in berries (they affect the activity of enzymes in the body, enhancing the beneficial properties and quality of food consumed).
The higher the concentration of these elements in the fruit, the darker their color and the more useful the peel. Therefore, black berries (grapes, blueberries, currants, mulberries, irga) are considered the most useful.
Dark berries contain:
- sugar (glucose and fructose);
- an extensive vitamin complex;
- a large set of organic acids;
- bioflavonoids;
- pectins.
Flavonoids, in addition to the general effect on the absorption of nutrients by the body, have the following properties:
- antioxidant;
- spasmodic;
- anti ulcerative;
- antineoplastic;
- healing;
- anti-inflammatory;
- diuretic;
- bactericidal.
Due to the set of nutrients, black grapes deserve special attention. Its berries contain a large amount of antioxidants, the protective properties of which resist the formation of free radicals.
Black grapes as a preventive measure
Regular consumption of the product has a beneficial effect on human health:
- helps to lower cholesterol levels;
- prevents the occurrence of atherosclerosis;
- prevents blood clots.
When eating black grapes, blood pressure normalizes, the walls of blood vessels are strengthened, and micro-blood circulation improves. The content of nutritious monosaccharides and their rapid assimilation in the body have a tonic and restorative effect, contributes to the normalization of metabolic processes and brain function.
What grapes to choose for diets: comments of nutritionists
When choosing the most dietary variety for weight loss or maintaining health, it is important to consider the taste of the berries, and not their calorie content. Nutritionists recommend:
Sour grapes contain more organic acids, so they are ideal for losing weight and stabilizing digestion.
Sweet and aromatic fruits contain more fructose and sucrose, therefore nutritionists recommend them for diabetes (to restore blood sugar levels) and problems with the gastrointestinal tract, but for those who lose weight, the use of such varieties is not recommended.
Organic acids affect the composition of gastric juice, as a result of which:
- assimilation of food improves;
- increased appetite;
- the intestinal microflora is normalized;
- increased peristalsis.
The color of the berries also affects the dietary value of the product, since much less black fruits are needed to replenish the body with the necessary microelements.
By consuming small servings of grapes every day, you can regularly replenish the supply of micro and macronutrients such as potassium, calcium, magnesium, iron and zinc.
The benefits of grapes in cosmetology
Even in ancient Egypt, women knew the wonderful properties of grapes, which help to care for the skin and keep it youthful. In modern cosmetology, preparations based on grape seed essential oils carefully care for the skin, improving its elasticity and firmness, remove dead tissue, nourish, whiten and moisturize. They help to preserve beauty, youth and health for many years.
Contraindications to use
Despite all its usefulness, black grapes also have contraindications:
- The dark color makes the berry a strong allergen, so it is contraindicated for young children under one year old;
- It is not recommended to consume fruits and juice at the final stage of pregnancy and during breastfeeding;
- With ulcers and oncological diseases of the stomach, diabetes mellitus, diarrhea, obesity, edema, chronic constipation, acute forms of tuberculosis and colitis, the use of berries is contraindicated.
Black grapes can replace a number of foods in the diet, especially during the spring beriberi. Consult a doctor and a nutritionist, consumption in moderate doses (5-10 berries per day) will not harm the body, even with the indicated contraindications, and will keep it young and healthy. If you have an allergic reaction, you should switch to green or yellow grapes.
Outcome
Like any food product, grapes have their own benefits and contraindications. The rich chemical composition makes the berry an irreplaceable component in the diet of every person. In the food industry, winemaking and cosmetology, grapes occupy well-deserved first places.

Vines are also used in folk medicine.... The ash after the burned vine is effective for hemorrhoids and nervous system exhaustion. It is recommended to drink an aqueous infusion of ash for bruises. Ash from the shoots, with the addition of olive oil, is effective for weakened joints, as well as muscle tears.
In addition, grape wine is considered a panacea for various ailments. It is used for anemia, to improve appetite, normalize blood pressure. Eating 1 tbsp daily l. red wine promotes the elimination of radionuclides.
And also from the leaves of the plant, medicinal decoctions and infusions are prepared, which are used for dermatological pathologies, for gargling with sore throat, periodontal disease. The juice from the leaves is effective for dysentery as well as vomiting.
The use of seeds with seeds for men and women
For the male body, grapes are considered a natural remedy for maintaining sexual function. The plant contains polyphenol, which activates metabolic processes. And also studies have shown that the berry helps a man to overcome infertility.
Grapes have unique and beneficial properties for women:
- Berries reduce the harmful effects of ultraviolet radiation on the body and prevent skin cancer.
- Essential oils support skin elasticity and keep it youthful.
- Prontocyanides reduce the risk of developing breast cancer and help fight it.
- Phytoestrogen normalizes hormonal levels.
- Glucose protects against stress, relieves depression, improves mood, normalizes the nervous system.
- This plant is considered a natural aphrodisiac.
In addition, it is used for weight loss. Although it contains enough calories, it satiates quickly and keeps you healthy.
The grape is a berry with many beneficial properties. However, the results will be noticeable with moderate use.
It is difficult to isolate the elements that are present in abundance from the vitamin-mineral complex contained in grapes. Of course, there are useful substances in the berry, but in relatively small quantities. But grapes are rich in simple sugars and carbohydrates, but proteins and coarse fibers in their composition are minimal. Note that the differences between different grape varieties (for example, with and without seeds) are insignificant.
But the situation changes dramatically when it comes to raisins. Dried grapes contain more minerals, fiber, and most importantly - much more sugar and carbohydrates, which leads to a sharp increase in calorie content. Thus, it is best to consume the berries fresh. And it is recommended to exclude raisins from the diet, especially for people who want to lose weight.
Healing properties
As mentioned above, grapes are not considered a vitamin bomb, but their nutrients still make a valuable contribution to the body. For example, copper is involved in energy production, and together with vitamin C, it is responsible for collagen formation. Potassium, in turn, is essential for cellular metabolism. A number of trace elements (calcium, magnesium, phosphorus, manganese) and vitamin K help to strengthen bones. By the way, 100 g of berries provides 28% of the daily intake of vitamin K, which the body needs not only for healthy bone tissue, but also for normal blood clotting. In addition, the berries contain small doses of beta-carotene, lycopene, lutein, etc.
The antioxidants found in grapes help reduce oxidative stress in the body, which is known to be the root cause of many chronic diseases of the nervous and cardiovascular systems. Note that dark berries have a more powerful antioxidant effect, since they contain natural anthocyanin pigments.
In addition to reducing oxidative stress, the flavonoid complex supports the normal functioning of the cardiovascular system in several other ways. First, these substances reduce the risk of blood clots by preventing platelets from sticking together. Secondly, due to the production of nitric oxide, they dilate blood vessels, reducing the risk of heart attack and hypertension. In addition, there is a little phytosterol (a plant analogue of animal cholesterol) in grapes, which prevents the formation of plaques on the walls of blood vessels and, thus, protects the body from atherosclerosis.
However, the antioxidant substance resveratrol, which belongs to the group of polyphenols, usually attracts the most attention in grapes. It is credited with anti-cancer and anti-aging properties. In addition, resveratrol is believed to be able to protect the brain from damage that leads to various neurodegenerative diseases, including Alzheimer's disease. Note that the amount of substance coming from grape berries is not so large as to prevent the development of a pathological process, but it can delay its occurrence.
As for the effect of resveratrol on cancer, experiments have shown that the use of juice from dark red grape varieties helped to reduce breast tumors in rats. This antioxidant also slowed down the development of agents that cause colorectal cancer.
Finally, resveratrol, along with zeaxanthin and lutein, has a positive effect on the health of the visual organs. This substance is involved in protecting the retina from ultraviolet radiation, thereby reducing the risk of developing age-related macular degeneration, glaucoma and cataracts.
It should be noted that a large number of biologically active elements (antioxidants, vitamin E) are concentrated in the seeds and skins of grape berries, therefore, it is recommended to eat whole grapes for maximum benefit. And by the way, do not believe the myths that pitted berries can lead to appendicitis. Moderate consumption does not provoke inflammation of the appendix.
Interestingly, all the beneficial properties of antioxidants are preserved during the fermentation of grapes, and therefore they can be obtained from wine. However, we note that we are talking about a drink from dark varieties, since white wine is mainly made using grape juice without pulp (skin and pits).
In medicine
Due to the presence of P-vitamin substances in the composition of red grape leaves, their extract began to be used as the main active ingredient in a preparation called Antistax. It is used for chronic venous insufficiency, hemorrhoidal lesions of veins, hypertension, various dental pathologies, and also as a neuroprotective and anti-inflammatory agent. This medicine does a good job of eliminating symptoms such as swelling, calf muscle cramps, and leg pain.
In addition, biologically active additives based on grape seed extract from dark varieties are now very popular on the phytopharmacological market. Manufacturers claim that, thanks to phenolic and tannins, as well as unsaturated fatty acids (linoleic and linolenic), these supplements support the health of veins and blood vessels, reduce the risk of blood clots, activate lymphatic drainage, normalize blood pressure, provide nutrition to brain cells, and reduce age-related visual impairment.
In folk medicine
The grape berries, along with other parts of the plant, are used in folk medicine to treat a wide range of ailments and diseases. There is even a separate direction - ampelotherapy (grape treatment). The plant is used for problems with digestion, vision and blood vessels, as well as for kidney disease, sore throat, bronchitis, periodontal disease, gout, migraine, etc. In addition, leaves, as well as decoctions and infusions from them are often used to treat skin diseases (boils, ulcers), wound healing.
Moreover, herbalists advise replacing cabbage leaves with grapes when preparing cabbage rolls. Such replenishment of the diet will help to establish the work of the pancreas and intestines. Surprising as it may be, even grapevine ash is used in folk medicine, helping with intestinal ulcers.
For rinsing the throat with angina or rinsing the mouth with periodontal disease, it is advised to make an infusion of grape leaves: 1 tablespoon of dry crushed raw materials is poured with one liter of boiling water and insisted for 2 hours. Then it is filtered and applied several times a day. The same liquid can be used to wipe wounds and sores on the skin.
Also, inflammation in the throat is treated with alcoholic tincture of grape seed. To prepare it, you need to wash 100 g of seeds of dark berries, blot with a napkin and crush in a mortar. Then pour 0.5 l of vodka, cover and leave in a dark place for 1 month, shaking regularly. After straining, add a few drops of the tincture to the herbal decoction and gargle with this mixture. You can also take this potion 1 teaspoon before meals. It helps to strengthen the walls of blood vessels, helps to fight varicose veins and prevents platelets from sticking together.
Traditional healers offer a decoction of grape leaves to treat gout, metabolic disorders and night blindness. To prepare it, you need to add 1 tablespoon of dry raw materials to 200 ml of boiling water and leave on low heat for 10 minutes. After straining, the medicine can be taken in 50 ml four times a day. In addition, to speed up the wound healing process, it is advised to wipe the affected skin.
In addition, the broth can be prepared using grape seeds: usually take one glass of boiling water per tablespoon of seeds, and then put in a water bath for 20 minutes. After straining, it is recommended to drink this liquid 1 tablespoon three times a day before meals. It has a strong diuretic effect.
Grape wines were used as medicines in Ancient Egypt and Ancient Greece. Then they were treated for both physiological ailments and mental disorders. In addition, they were added to water for the purpose of disinfection. And by the way, it was not at all useless, since they are indeed toxic to certain types of bacteria.
Today wine is also actively used in folk recipes. For example, for headaches and migraines, it is recommended to mix dry red wine, honey and aloe juice in a 1: 1: 0.5 ratio. Take a teaspoon three times a day for a month. According to another recipe, you need to pour red dry wine over a jar filled with raspberries. Insist for 3 weeks in a dark place, and then take 50 ml three times a day 30 minutes before meals. Red wine itself is considered a good remedy for insomnia. Usually, it is enough to drink 100-150 ml an hour before bedtime.
It is used in folk medicine and white wine. For example, to remove small stones from the kidneys, it is necessary to pour 100 g of marshmallow seeds with two liters of dry white wine and leave to infuse in a dark place for 4 weeks, shaking from time to time. Then you need to boil the liquid over low heat for 30 minutes, strain and use 50 ml three times a day before meals.
In case of problems with urination, one liter of boiling dry white wine is poured into 30 g of dry birch leaves and left on low heat for 15 minutes under a lid. Then the liquid must be filtered, add 3 tablespoons of honey and drink 70 ml three times a day one hour after meals.
Traditional healers claim that 1 glass of grape juice in the morning can relieve headaches. They are also advised to treat kidney disease. For a month, you should drink 1 liter of grape juice daily with the addition of 10-12 drops of lemon juice. With proteinuria (the appearance of protein in the urine), you need to drink such a mixture in one gulp, and the induced urination should flush the urinary tract.
In oriental medicine
In ancient oriental medicine, grapes (both the berries themselves and the rest of the plant) were highly valued for their medicinal qualities. The vineyard was classified as a cold yin-type and was considered a dry product in the II degree, but ripe berries were hot in the I degree and moist. Healers claimed that if you knead young branches of grapes with leaves and tendrils, and then mix them with barley flour and apply to the body, you can get rid of hot headaches or hot swellings.
Juice from grape leaves helped to get rid of problems with a hot stomach: it stopped vomiting, bilious diarrhea, and healed ulcers. It was believed that it has a diuretic effect, saves from hemoptysis and increases potency. It was recommended for pregnant women as it strengthened the developing fetus. The topical application of the juice was supposed to stimulate hair growth. The gum of the vineyard, according to ancient healers, cleansed and dried nature. And together with wine, they cleared the spleen well and healed eczema.
Used in healing practices and grapevine ash. By mixing it with vinegar, they obtained a cure for hemorrhoids, and by adding vegetable oil and honey to this mixture, they prepared an antidote for snake bites.
Hot berries normalize the disturbed nature and strengthen the organs in the chest area. Grape juice is good for the stomach, kidneys, liver and bladder. Grape oil, in turn, warms up the body well and stops the development of tumors.
In scientific research
Grapes are often the subject of scientific research. Most of the attention of scientists is focused on its anti-cancer properties. It is believed that antioxidants, found mainly in the skins and seeds of berries, are effective both as a preventive measure and as an adjunct to cancer therapy if the disease has already developed. For example, resveratrol, according to scientists, helps reduce oxidative stress and thus protects the rectum, breast, prostate and lungs from cancer.
But one of the latest studies has shown that grape juice extract with its phenolic composition significantly reduces the viability of pathogenic cells in case of rectal lesions. In the experiment, we used raw materials obtained from the berries of the Autumn royal and Ribier varieties. By the way, depending on the dose, the extract not only led to cell death, but also reduced their mobility, slowing down the process of metastasis. And yet another experiment demonstrated that in colorectal cancer, infected cells are vulnerable to proanthocyanids isolated from grape seeds.
There are also several scientific papers supporting the effectiveness of various constituents in grape berry in the fight against breast cancer. Scientists claim that grape seed extract has a significant effect on cell motility in mice for breast cancer. Thus, they inhibit the formation of metastases in other organs. In another study, the metastasis process was stopped by polyphenols extracted from the skins of grape berries. True, they influenced the viability of infected cells to a much lesser extent, mainly limiting their mobility.
As for the prostate tumor, after a series of experiments, scientists came to the conclusion that the anthocyanins contained in the dark grapes of the Muscadine variety have a destructive effect on pathogenic cells without touching the healthy epithelium. They also help prevent the spread of bone metastases.
Note that in all the above studies, the anti-cancer properties of various components from the composition of the grape berry were studied, but each group of scientists focused on a specific substance, without considering it in combination with other components. On the one hand, this made it possible to learn in more detail about all the properties of one or another antioxidant. On the other hand, it did not allow to see the results of its interaction with other substances.
That is why scientists from the University of Wisconsin took as the object of their research all the polyphenols found in grapes (resveratrol, quercetin, kaempferol, catechins, anthocyanins, etc.). So, they came to the conclusion that, entering the body along with other antioxidants, the effectiveness of many of them is enhanced. This synergistic effect is important at the stage of preventing the development of oncological diseases.
These studies were confirmed by an experiment carried out by a group of American scientists. For two weeks, 30 people at risk of developing colorectal cancer were given up to 450 grams of grapes per day. As a result, after the end of the experiment, the risk of the disease decreased, especially in people after 50 years. If the pathological process has already started, then, naturally, the amount of polyphenols contained in grapes, and in any other fruit or berry, will not be enough to treat the disease. To achieve the desired effect, it would be necessary to eat tens of kilograms of berries per day.
In addition to studies studying the effect of grapes and its individual components on cancer, a few years ago there was a scientific work in which Australian David Sinclair argued that resveratrol isolated from wine slows down the aging process of cells. This discovery quickly spread throughout the world media, but journalists often missed important nuances. For example, the fact that the experiments have so far been carried out only on mice. And the level of resveratrol in the rodents was so high that it would take several hundred glasses of wine to reach it.
By the way, the bioavailability of resveratrol is not very high, that is, it is poorly absorbed from food and drinks. Scientists have found that the highest concentration of this antioxidant is in the skins and seeds of berries of dark wine varieties. In addition, frequent rains during grape ripening increase the amount of bioavailable resveratrol in the skins, but does not affect the content of this substance in the seeds.
However, all this is still not enough for the body to receive a biologically active dose. Scientists from Johns Hopkins University have been monitoring the health of the elderly in the Chianti region of Italy for 9 years. Their traditional diet includes many foods that contain resveratrol. But researchers have never been able to establish a link between lifespan or aging rate and the level of resveratrol in the body.
But numerous studies of grape polyphenols have confirmed that these substances are able to maintain the normal functioning of the cardiovascular system. By lowering cholesterol levels and stimulating nitric oxide production, they help prevent atherosclerosis and improve endothelial function.
In one experiment, 69 adults were divided into three groups. Participants in one of them were given 500 g of dark grapes every day for eight weeks, participants in another - 500 g of berries of light varieties, and the rest were completely excluded from the diet. As a result, those who ate the dark varieties experienced significant reductions in their "bad" cholesterol levels. White berries were inferior in efficiency, but still led to an improvement in performance compared to the third control group.
Despite the high sugar content in grapes, scientists argue that it may be beneficial for patients with type 2 diabetes. In a 16-week experiment, 38 men took 20 g of dark wine grape extract daily, after which their blood sugar levels decreased compared to the control group. In addition, resveratrol increases insulin sensitivity, which helps the body process more glucose and thus helps lower blood sugar levels.
Slimming
There is no unequivocal opinion about the benefits of grapes for weight loss. Some nutritionists call these berries the most useless of all, other experts willingly include them in various diets. It usually speaks against grapes that they contain a lot of sugars and carbohydrates. On the other hand, its glycemic index is not that high - 45 units, which means that grapes do not cause a sharp rise in blood glucose levels.
In addition, some of the substances in these berries increase insulin sensitivity and, thus, help to improve the absorption of sugar in the body. Moreover, American scientists conducted an experiment in which people with significant excess weight took part. They were divided into 3 groups and took 30-minute walks daily for three weeks. The first group added grape juice to the diet, the second - grapes, and the third - no changes were made. As a result, after 3 weeks, representatives of the first group lost an average of about 1.5 kg of weight, the second - about 2 kg, and the third - about 0.5 kg.
Nutritional researchers concluded that grapes improved insulin metabolism and inhibited fat storage. Berries had the best effect because most of the essential substances are concentrated in the skin, which usually does not get into the juice. Thus, grapes should not be discounted, because with moderate use and in combination with little physical exertion, it benefits the body and helps to gradually get rid of excess weight.
But all this cannot be said about raisins - one of the most terrible enemies of weight loss. It practically does not contain nutrients and consists of 60% sugar, not much different from sweets. The calorie content of raisins (299 kcal) is 4 times higher than the calorie content of grapes (67 kcal).
Note that when losing weight, they usually pay little attention to drinks, mainly trying to limit themselves in products. However, special care should be taken when drinking wine, as the average 175 ml glass contains 160 kcal. The calorie content depends on the variety of grapes used and even more on the amount of added sugar, but in any case it remains quite high.
In cooking
Grapes are used in all cuisines of the world. In addition to the berries themselves, the leaves of the plant are used, from which, in the Middle East, for example, dolma is prepared. In addition, during the preparation of red wine, scallops are often used along with berries (twigs to which grapes are attached). As for the berries themselves, they are dried, pickled, they are used to make jams, ice cream, compotes are cooked, they are added fresh to various desserts, salads and even served with meat.
Grapes are often used to make snacks. Since it goes well with cheeses and nuts, it can be dipped in soft goat cheese, then poured over with honey and sprinkled with chopped pistachios. These balls must be refrigerated for 45 minutes, and then can be served. By the way, if we are talking about cheeses, then grapes can be safely served with blue cheese. And the peculiarity of the French cheese "Arôme au gêne de marc", reminiscent of brie, is that it is kept in a grape brandy for 30 days along with the seeds, skins and sprigs of grapes left after pressing.
Real balsamic vinegar is made from grape juice. First, it is boiled down to a thick syrup consistency and then kept in barrels for at least three years. Also, from the juice of grapes in the Transcaucasus, a traditional sweet is prepared, which the Armenians call "sudjuk", and the Georgians call "churchkhela". The juice is boiled until its volume decreases 3 times, then a little flour is added and nuts strung on a thread are dipped in this syrup. Then the resulting "sausage" is dried in a cool dark place.
Special wine grapes are usually grown to make wines, but some winemakers go even further. For example, Tokaj wines in Hungary and several expensive wines in France are made from grapes covered with gray mold. This helps the berries to get rid of unnecessary moisture and increase the concentration of sugar. In addition, there is the so-called ice wine, which is made from grapes caught in the first frost. By the way, frozen grapes are often used as ice. They cool the drink without diluting it with water.
In cosmetology
In cosmetology, grapes have been used for quite a long time and successfully. The beauty industry actively uses extracts and extracts from the skin and pulp of berries, seed oil, and the antioxidant resveratrol. You can find these ingredients in a wide variety of products: hand and face creams, cleansing foams, scrubs, anti-cellulite gels, shampoos, lip balms, lipsticks, nail coatings, and anti-aging products.
The most common and popular ingredient is grape seed oil. Due to the presence in its composition of vitamins A and B, tocopherols, flavonoids and polyunsaturated acids, it nourishes the skin well and does not leave any shine or film feeling on the face. Regular use of products based on this oil stimulates the regeneration processes of the skin and gives it elasticity.
For oily skin:
- mix 2 tablespoons of dark grape juice with egg white and a little starch or flour. This mixture is applied to the face for 15-20 minutes, and then washed off with warm water;
- a handful of dark varieties of berries, mashed into gruel, are mixed with sour cream until a thick mass is obtained. Apply on face for 20 minutes and then wash off with a cotton pad dipped in cool milk.
For dry skin:
- combine egg yolk, a tablespoon of honey, half a teaspoon of olive oil, a tablespoon of chopped oatmeal with a tablespoon of red grape juice. Apply on face for 15 minutes, then rinse with warm water.
Cleansing Lotion:
- 400 ml of dark grape juice must be mixed with two tablespoons of honey and 200 ml of vodka. Store in a refrigerator in a glass container for no more than 7 days. Wipe your face twice a day.
Harm of grapes and contraindications
In moderation, grapes are extremely beneficial to the body. But too large portions can provoke an upset stomach and gas formation. In addition, some experts believe that grapes should not be consumed by pregnant women, since resveratrol becomes toxic when hormones are unbalanced. In addition, it is not easy for a weakened digestive system to digest the skin of the berries. It may not be necessary to completely abandon grapes during pregnancy, but its inclusion in the diet should be done with caution.
In the situations listed below, it is better to refuse the use of grapes:
- exacerbation of stomach ulcers;
- exacerbation of gastritis or colitis;
- taking blood thinning drugs (for example, warfarin).
It is also necessary to give grapes with caution to children under 4-5 years old. The fact is that babies often swallow whole berries without chewing them. The grape can become stuck in narrow airways and, due to its soft and smooth surface, create an airtight seal, blocking the flow of air. It is best to cut the berries in half before giving them to your child.
We have collected the most important points about the benefits and possible dangers of grapes in this illustration and we will be very grateful if you share the picture on social networks, with a link to our page:
Grapes are exported to almost all countries of the world, and recently breeders have done a lot to expand the geography of growing these berries. Interestingly, grapes were actively cultivated in many republics of the Soviet Union. At that time, his image could be seen on the coats of arms of Moldova, Armenia, Georgia and Turkmenistan. Unfortunately, during the anti-alcohol campaign, a huge number of vineyards were barbarously cut down. And yet, today about 80 thousand square meters. km. the territory of our planet is planted with this plant.
Problems arose with the production of wine during Prohibition in the United States. However, no one destroyed the vineyards there, and enterprising Americans began to produce very hard concentrates of grape juice, which were called "wine bricks". To avoid problems with the law, sellers applied a warning to the briquette that the brick dissolved in water should never be stored in a cool, dark room for 21 days, thereby creating an excellent advertisement for their product.
As for the former Soviet republics, after the collapse, winemaking traditions were renewed with renewed vigor. Georgia and Moldova have been particularly successful in this. By the way, not so long ago, the remains of an ancient jug were found in Georgia, on the fragments of which clusters were depicted. Very old seeds of wild grapes were also found there.
The fact that in ancient times grapes were no less popular than they are now is evidenced by references to them in mythology, art and the Christian religion. So, for example, the Bible says that the first plant planted on Mount Ararat after the great flood was precisely the vine. The ancient Slavic goddess of fertility Zhivu was always depicted with an apple in one hand and a bunch of grapes in the other. The ancient Greek poet Homer wrote about eating grapes in the Odyssey. Also, images of berries often appeared on the coins of different states.
As for painting, in all eras, vines and bunches were depicted in still lifes. Moreover, in the Middle Ages, these berries were often used as a symbol of the Holy Communion - the blood of Christ. In addition, grapes are found on the canvas of Karl Bryullov "A girl picking grapes in the vicinity of Naples" (1), Michelangelo Caravaggio "A young man with a basket of fruits" (2) and in the painting "Red grapes in Arles" by Vincent van Gogh (3). By the way, this canvas is considered the only work sold during the artist's lifetime.
Grapes are immortalized not only through painting, but also in other ways. For example, in 1913 the name Vinifera, which translates from Latin as grape, was given an asteroid. And in France, Israel, Turkey, Russia, Tunisia and many other countries, monuments have been erected depicting bunches or the harvesting process. Also, themed festivals and celebrations dedicated to the collection of wine berries are held around the world.
By the way, about the holidays and related traditions: in Cuba it is customary to pour water out of the window on December 31, wishing the new year a clean path, and directly at midnight, to the chimes, Cubans eat 12 grapes - this is considered a guarantee of the realization of the wish. Portuguese New Year's tables are not complete without grapes. There, these berries are considered a symbol of abundance and happiness.
Selection and storage
When choosing grapes, it is necessary to give preference to bunches with whole, dense berries without damage, rot and mold. Light brown dots on white grapes indicate that they are very ripe and ready to eat, but they will not be stored for a long time even in the refrigerator. You should not refuse to buy grapes if a light whitish coating is noticeable on the berries, since this is their defensive reaction to external stimuli. Sometimes white traces of chemicals can remain on the berries after processing, so in any case, the grapes need to be washed well.
As for storage, usually ripe berries are in the refrigerator for about 3 days. It is best to put them in a plastic or glass container, as moisture accumulates in the bag, and fungal infections can develop in combination with the sugar released with grape juice. To preserve the harvest for the winter, it is necessary to remove the grapes from the bunch and, spreading them on a tray in one layer, send them to the freezer. After a while, they can be transferred to any container and stored until the end of winter. This method allows you to preserve the maximum amount of nutrients.
Pickling, canning and drying robs the grapes of virtually all vitamins, minerals and antioxidants. In the case of raisins, questions also arise about the production process, since almost all dried fruits, in order to prevent spoilage and preserve their presentation, are treated with preservatives (for example, sulfur dioxide). If you still decide to buy dried grapes, then you need to soak it for half an hour in cold water, and then rinse well.
Varieties and cultivation
Grape varieties are striking in their variety, and breeders continue to work to improve their chemical composition, taste and make it possible to grow in different climatic conditions. Typically, grape varieties are divided into table (eaten fresh) and wine (used to make wines). Among the former, seedless berries (for example, raisins) are often found. Also, grapes are distinguished by color: white, pink, red and black. The most common varieties in our country are: Veles, Adler, Jupiter, Muscat, Ladies fingers and Chardonnay.
Among the unusual varieties of grapes are "Witch's fingers". These dark berries really resemble short fingers in their elongated oblong shape. And the fruits of the Cotton Candy variety do not outwardly differ from others, but the breeders have endowed them with a pronounced taste of cotton candy. They contain 12% more sugar and have almost no astringency, which makes them very popular with children.
It is impossible to ignore the variety "Roman Ruby", which is grown and sold at auction exclusively in the Japanese prefecture of Ishikawa. These red berries contain 18% sugar, so they are particularly sweet. Their size is also striking - each grape must weigh at least 30 g, and the entire bunch must weigh at least 700 g. In 2017, a sprig of such grapes was sold at an auction for $ 9800.
The so-called sea grapes and the Brazilian Jaboticaba grape tree are of great interest. True, none of these plants has any relation to the Grape family. They probably got their names solely for visual similarity. Moreover, under the name "sea grapes" is immediately hidden and the type of algae, which are eaten, and fruiting evergreen trees. Jaboticaba, on the other hand, is the edible fruit of a plant from the Myrtle family.
As for the peculiarities of growing grapes, the choice of location is considered a key factor. The berries tolerate heat well, but they are afraid of the shade, so for planting it is better to choose a sunny side, protected from the wind. The soil can be sandy, clayey, or black earth. With frequent precipitation, the plant can not be watered, but if there is a lack of moisture or drought sets in, then additional measures are needed. In the absence of rain, you need to water the grapes up to 10 times per season, but not too abundantly.

Hello dear friends!
Grapes (useful properties, contraindications) will be the topic of our discussion.
If we compare the wonderful taste qualities of various grape varieties and the benefits that we get from its use, I even find it difficult to answer what personally attracts me most to this berry.
Each variety is attractive in its own way. A completely unique aroma of black grapes. The sweetness of the quiche-misha, the refined aroma of Isabella, the juicy pulp of white grapes. Just beautiful. I get pleasure and even my mood rises when I have a huge bunch of fresh grapes on my table in a beautiful plate.
And at this time I don't think about the benefits, health, vitamins and minerals, because the emotional and taste sensations at the time of the meal are in the first place for me. Having thus satisfied your gastronomic needs, you can talk about the beneficial properties of these wonderful fruit berries.
Grapes. Composition and useful properties
In the first place, I would attribute those components that are contained in the peel and seeds to the beneficial properties of grapes. From this point of view, the most valuable varieties are black grapes.
What are these special substances? This, or 
bioflavonoids, which primarily include resveratrol and quertecin. This also includes grape seed oil, which is rich in unsaturated fatty acids. Just do not try to crunch all grape grains and grind the rough skin with your teeth. All the pleasure of eating grapes will be lost and this activity will not bring benefits. Only the intestines are clogged.
Grape oil is sold in specialized stores. Buy it and add it to vegetable salads. Very tasty and healthy. But obtaining antioxidants from the peel and seeds requires special cooking technologies, always in an industrial environment. Finished products are sold in the form of dietary supplements, i.e. in special capsules, tablets or concentrated juices.
Due to the fact that grape berries have protective antioxidant properties, it is possible to be very successful in the prevention of heart disease and oncological processes, to reduce the content of low density lipoproteins and cholesterol. And all this can be done in the most natural way - just eating grapes with pleasure!
Interestingly, cosmetologists have long noticed these beneficial properties of antioxidants and have adopted them. All biologically active substances can be found in grapes, including antioxidants, which help to maintain the health of the skin of the face and body.
Now on sale there are creams and masks with an extract from the seeds and skins of grapes, dietary supplements with anti-cellulite properties, new generation lotions, massage oils from grape seeds are produced. All this, with constant use, creates a stunning rejuvenating effect that women like so much.
What other biochemical constituents are present in grape berries and give wonderful health to our body?
The grapes contain up to 6% tartaric and malic acid, gluconic and citric, succinic and oxalic. They give the berries a sour taste and provide many medicinal properties.
There are also minerals necessary for the human body. More than 60% of all trace elements are potassium, manganese, magnesium, rare trace elements (chromium, cobalt, nickel, etc.). They are essential elements for building enzymes and hormones, vitamins and proteins. Potassium improves heart function.
Grapes contain many vitamins: vitamin A, B1, B2, niacin or vitamin PP, B5 or pantothenic acid, B6, folic acid, vitamin C, biotin, vitamin K, flavonoid (vitamin P). Biochemical processes in a living organism, cellular metabolism occurs with the participation of natural vitamins. And they are very rich in grapes.
Grape berries contain up to 1.5% pectin. These are polysaccharides, which are structural elements of dietary fiber from grape skin. That is why berries perfectly cleanse our intestines.
Amino acids are found in grapes: lysine, histidine and arginine, methionine and leucine, cystine, glycine, which are involved in the metabolism, bringing plastic building protein material into our body.
