Scientists have proven that fiber from grape skins and seeds contains a lot of antioxidants that reduce the risk of cardiovascular disease.
New research has shown that black grape extract is extremely effective in fighting heart attack and, most importantly, unlike other seeds and grains that are a rich source of either antioxidants or fiber, black grapes are rich in antioxidants and fiber, writes the Daily Mail.
Thus, during the research, scientists were able to prove that the fibers found in the peel and seeds of grapes contain a lot of antioxidants that reduce the risk of cardiovascular disease, which are the world’s number one “killer”. Of these diseases, Finland has the most cases in Europe, while Americans are in the lead in the world in general.
Experts believe that black grape extract could lower high blood pressure and reduce cholesterol by 14 percent, while in addition to a Mediterranean diet based on olive oil, tomatoes, and wine, the risk of cardiovascular disease would be reduced by as much as 50 percent.
Grapes are the fruit of a plant with the Latin name Vitis vinifera. The grape berry has a crispy texture and a sweet, dry, or astringent taste. The transparent flesh is wrapped in smooth skin. 100 g of fresh fruit contains 69 kcal or 288 kJ of energy, 0.72 g of protein, 0.16 g of fat, 18.10 g of carbohydrates, 0.9 g of dietary fiber, and 15.48 g of sugar. Grapes are a good source of vitamin C (11 mg, which is 14% of the recommended daily intake). It contains phosphoric acid, all B vitamins except B12, which are important for carbohydrate metabolism and have a beneficial effect on the nervous system. Grape berries contain magnesium, manganese, and potassium.
Grapes are a high-value source of bioflavonoid phytochemicals. It is a specific group of plant pigments (colors) that are being intensively researched today. A more pronounced grape color means a stronger concentration of bioflavonoids. These substances have a pronounced antioxidant potential, ie. protect cells from the harmful effects of free radicals. Numerous evidence shows that the polyphenols present in wine have a beneficial effect on heart health. In a new study, they found that grapes, with their polyphenol components, also have a protective effect on the heart. Polyphenols from grapes (which are also found in wine), resveratrol, anthocyanins, catechins, and quercetins, act in two ways: they collect and inactivate free radicals, and reduce the formation of malondialdehyde, a by-product of oxidation.
It has also been shown that the consumption of grapes improves blood flow as it prevents the accumulation of red blood cells in the arteries, improves the capacity of the heart, and reduces the extent of tissue destroyed after a heart attack. Consumption of grape juice has a threefold effect: it raises the level of nitroxide, which helps reduce vascular congestion, reduces red blood cell aggregation, and increases the level of alpha-tocopherol, which as an antioxidant increases the antioxidant properties of plasma by 50%. The phenolic ingredient resveratrol in grape skin inhibits the action of proteins involved in cell regulation, as well as enzymes and hormones that contribute to high blood pressure and heart disease.
Grape residues can be used to fight as many as 14 types of bacteria, including Escherichia coli and Staphylococcus aureus, research shows. The skins of grape berries are rich in ballast substances and improve bowel function and eliminate constipation while removing excess water from the body, remove toxins, and bind fatty substances. Grapes are ideal for autumn diets. Accelerates the flow of urine through the kidneys, bladder, and urinary tract. Grapes act as a natural tonic for the body, and it is also a portion of very nutritious food. The seeds should be chewed carefully because they contain an active substance that acts to lower cholesterol.
