Grape is one of the types of fruits grown thousands of years ago. It is available in different varieties, including green grapes, red, black, yellow and pink. Grape contains seeds that cannot be eaten, and their seeds are edible. In the mild climate around the world, grapes provide a range of health benefits due to its high content of nutrients and antioxidants that are available at a higher concentration in the outer crust and seeds, and that is why most research is conducted on grapes using seed extracts or outer shell.
Benefits of grape seeds
Grape seed contains a very high amount of antioxidants. Grape seed extract, made from crushed and dried grape seeds, is a form of dietary supplement, and therefore contains very high concentrations of nutrients. The benefits of this extract are as follows:
- Blood pressure reduction: Several studies have found that the extract of grape seeds has an effect on high blood pressure, and the results showed that it significantly reduces systolic and diastolic blood pressure.
- Improved blood flow: Some studies suggest that grape seed extracts can improve blood flow and blood circulation by diluting blood, which reduces the risk of blood clots.
- Reduce the risk of heart disease: Grape seeds can help reduce LDL cholesterol, which is a risk factor for heart disease, arteriosclerosis, and reduces oxidation of heart and arterial tissue as a result of stress.
- Improvement of collagen and bone strength: Increased consumption of flavonoid compounds improves collagen and bone formation. The grape seed extract is a rich source of this compound. Numerous animal studies have shown its ability to increase bone strength and density, Bone loss and cartilage in cases of osteoporosis, but these benefits need further studies to prove their effectiveness in humans.
- Maintaining brain health: Flavonoids found in the grape seed extract help delay or reduce the risk of degenerative neurological diseases such as Alzheimer’s, improve the cognitive status, and prevent memory loss due to its anti-oxidant and anti-inflammatory properties. More human studies to prove their effectiveness.
- Improved kidney function: Grape seeds can reduce the risk of kidney damage, improve their health, and their ability to function by reducing oxidative stress and damage caused by kidney infections.
- Inhibition of the growth of infectious microbes: Grape seeds have antibacterial and fungal properties. Several studies have shown their ability to inhibit the growth of antibiotic-resistant and common-pathogenic bacterial strains and to prevent bacterial food borne diseases.
- Reducing the risk of cancer: The intake of large amounts of antioxidants such as many laboratory studies have shown the ability of the powerful grape seed extract to inhibit the formation of cancer cells in the breast, Stomach, liver, prostate, and pancreas, but this benefit needs more human studies to prove its effectiveness.
- Maintaining liver health: Grape seed can protect the liver from toxicity and damage caused by the use of drugs. However, more human studies are needed to prove this benefit.
- Wound healing: Creams containing grape seed extract can contribute to wound healing by stimulating the secretion of growth factors in the skin, so it can be considered an effective treatment for wound healing.
