Grapes are not just a tasty berry, but also a product with a rich history. It was cultivated back in the Neolithic era in the Middle East, and the secrets of its cultivation are captured in Egyptian hieroglyphs.
Today, there are more than 8 thousand grape varieties, and breeders are constantly developing new ones. Varieties are divided into table varieties (for fresh consumption), technical varieties (for winemaking) and universal varieties, suitable for both food and wine production. The calorie content of grapes depends on the variety: the record holder is sultanas - 270 kcal per 100 g, but on average this figure is lower.

Grapes are a storehouse of vitamins (C, K, group B), phytonutrients, potassium and copper. However, it is important to know that the highest concentration of nutrients is not in the pulp, but in the peel and seeds.
Six beneficial properties of grapes:
1. Extension of youth
Grapes contain more than 150 types of flavonoids and other antioxidants. These substances play a key role in the fight against free radicals - unstable molecules that damage cells, accelerating aging and triggering the development of various diseases, including Alzheimer's and Parkinson's.
2. Increased immunity
Resveratrol, an antioxidant found in red grapes, can stimulate the body's innate immunity. The effectiveness of this antioxidant increases significantly when combined with vitamin D.
Innate immunity, also known as the body's first line of defense, is responsible for fighting bacterial infections.
3. Helps prevent cancer
According to research, grapes not only act as a preventative against cancer, but also contribute to the overall health of the body. These berries have been proven to reduce the risk of developing breast, colon and prostate cancer. Grape seed extract has the ability to stop the growth of malignant prostate cells.
4. Cardiovascular support
Grapes are rich in polyphenols, which have a beneficial effect on the health of the cardiovascular system. These substances regulate the level of “good” cholesterol, strengthen the walls of blood vessels and reduce the risk of developing atherosclerosis. Red and black grapes are especially rich in polyphenols.
In addition to polyphenols, grapes contain resveratrol, which also plays an important role in the prevention of cardiovascular diseases.
It is worth noting that 100 g of grapes provides 28% of the daily requirement of vitamin K, which is necessary for the production of prothrombin and osteocalcin proteins, which are involved in blood clotting and bone tissue building.
5. Help prevent diabetes
Regular consumption of grapes reduces the risk of developing type 2 diabetes. It is noteworthy that this effect is more pronounced in women than in men.
At the same time, frequent consumption of grape juice, on the contrary, can increase the risk of developing diabetes.
6. Maintains strong bones
Vitamin K and copper contained in grapes play a key role in the formation and strengthening of bone tissue. Copper deficiency in the body can lead to growth retardation.
Including grapes in your diet at any age will help maintain healthy and strong bones.
Harm of grapes
Grapes contain a lot of fructose. Excessive consumption can lead to bloating. Therefore, it is not recommended to use grapes as a snack between meals or on an empty stomach.
People suffering from diabetes or gestational diabetes during pregnancy should consume grapes with caution.
Grapes can also cause allergies. If you have diseases of the digestive system, it is not recommended to swallow grape seeds.
