Grapes are a fruit enjoyed by many from summer to fall. Fully ripened grapes are sweet and delicious, but eating them can sometimes be inconvenient because of their skins and seeds. Unlike apples or pears, grapes are not easy to peel or de-seed elegantly, so people often set aside the skins and seeds while eating. However, grape seeds, which were once discarded, have recently been gaining attention.
In fact, the history between grapes and humans is very long. In ancient Egypt, the various benefits of grapes were already known at least 6,000 years ago. Ancient Greek philosophers praised the advantages of grapes, and they were widely consumed during the Roman Empire as well. Even today, grape festivals are celebrated in various parts of Europe.
Why have grapes been so beloved for such a long time? It is not simply because of their sweet taste. The ancients valued grapes not only for their flavor but also for their various health benefits, such as helping to restore energy. These benefits were not limited to grape juice alone. Grape leaves were used to treat hemorrhoids and served as hemostatic agents, anti-inflammatories, and pain relievers, while raisins were helpful for relieving constipation and quenching thirst.
Recently, the U.S. Department of Agriculture has taken notice of the benefits of grapes and conducted research on the byproducts of grapes that were discarded at California vineyards. Until now, grape skins and seeds were either thrown away or used as livestock feed. Research revealed that grape seeds are beneficial for weight loss, improving fatty liver and cholesterol levels, and preventing diabetes and peripheral artery disease.
Grapes and Grape Seeds Nutritional Information
Grapes and grape seeds contain a variety of beneficial components, including vitamin E, flavonoids, linoleic acid, and resveratrol. Among them, the polyphenol known as OPC is recognized as a powerful antioxidant, with levels 50 times greater than vitamin E and 50 times greater than vitamin C. This strong antioxidant plays a major role in maintaining and improving the body’s health functions. OPC also protects healthy cells in the body and helps maintain skin elasticity by preventing UV-induced skin damage and wrinkle formation. It has been proven effective against brown spots caused by melanoma, ultraviolet rays, hormonal imbalances, and cosmetic toxicity. In addition, the linoleic acid found in grapes and grape seeds is known to promote blood circulation, remove bodily waste, alleviate symptoms of high blood pressure, and have a positive effect on cardiovascular diseases such as chronic venous insufficiency.
Grapes and Grape Seeds Benefits
Here are the commonly known potential benefits of grapes and grape seeds.
They Are Effective for Anti-Aging and Beauty
Grapes and grape seeds are rich in antioxidants that help prevent cell damage caused by free radicals and assist with various symptoms of aging. They also protect the skin from UV rays, helping to prevent skin troubles and skin cancer.
They Are Effective in Improving High Blood Pressure and High Cholesterol
The antioxidant components found in grapes and grape seeds, such as flavonoids and linoleic acid, help prevent blood vessel damage and support vascular health. When blood vessels are healthy, blood circulation improves, significantly reducing the risk of high blood pressure. Additionally, grapes and grape seeds are effective in lowering LDL cholesterol levels. As blood pressure and cholesterol levels stabilize, the risk of cardiovascular disease also decreases.
They Are Effective in Managing Diabetes
Diabetes is a dangerous disease where the sugar levels in the blood become abnormally high, leading to potential damage to blood vessels. This occurs when insulin is not secreted properly or its function is impaired. The antioxidant components found in grapes and grape seeds help improve this situation. Antioxidants suppress reactive oxygen species that interfere with insulin function and play a role in strengthening the immune system.
They May Help Prevent Cancer
Research is actively being conducted to determine whether grapes and grape seeds are effective in cancer prevention, and some studies have shown positive results. There is potential for them to be effective against various types of cancer, including breast cancer, stomach cancer, colon cancer, prostate cancer, lung cancer, and skin cancer. Of course, cancer is not an easily treatable disease, and its causes and symptoms are complex, so finding a complete solution may take time. While studies on the effectiveness of grape seeds are still in the animal testing phase, consuming them as food may help reduce the risk of cancer, even though they are not a cure-all.
They Are Effective in Preventing Vision Deterioration
Antioxidants play an important role in preventing cell damage caused by aging. Grapes and grape seeds are rich in antioxidants, which help prevent vision deterioration due to aging.
They Are Effective in Preventing Alzheimer’s Disease
Alzheimer’s disease is one of the main age-related diseases, and antioxidants play an important role in preventing cell damage caused by aging. The antioxidants abundantly found in grapes and grape seeds help in this role, aiding in the prevention of brain diseases associated with aging.
They Are Effective in Improving Hemorrhoids
Grapes and grape seeds help strengthen blood vessels. This has a positive impact on various blood circulation-related conditions, including hemorrhoids. By strengthening the blood vessels in the hemorrhoidal veins, circulation is improved, which reduces the size of the hemorrhoids and alleviates the symptoms.
It Helps Boost Immunity
One of the main benefits of antioxidants is enhancing the immune system. Antioxidants play a crucial role in preventing bacterial infections and healing cells that are already infected. Strengthening the immune system is vital for maintaining good health.
Recommended Intake and Side Effects
There is no exact standard for the amount to consume. Many researchers recommend 100-300mg per day. Grapes are generally considered a safe fruit, but like most plants, they may have side effects along with their benefits. People with a grape allergy should avoid grape seed extract. Additionally, symptoms such as headaches, scalp itching, dizziness, and nausea may occur.
