In fact, they may change the activity of the enzymes produced by the body for metabolism.
Anthocyaninsare a certain type of flavonoids. They are natural colors, which change in different environments. For example, they become blue in an alkaline environment. In the presence of acids, they are either red or pink. In neutral condition, they are purple. In highly acidic environments, they simply decompose. Anthocyanins are well-soluble in water, which is why we get perfect red wines from the skins of black or red grapes.

Its antihistaminic properties reduce the allergy reactions, the blood viscosity, and strengthen the immune system. Due to quercetin, it is possible to reduce the risk of cardiovascular disease and the level of free cholesterol in the blood.
Resveratrolis the same as phytoalexin. This is the substance that is produced by plants for protection against pathogens. Resveratrol can be found in all parts of the grapes, but its highest content is in the skin of black and red grapes. In fact, the properties of Resveratrol are many-sided. It is a strong antioxidant. In addition, it has anti-inflammatory effects, including preventing the growth of cancer cells. It also affects the leukemia cells, helping to stop the progression of the disease.
