Grapes have been recognized for their food and medicinal value for thousands of years; philosophers wrote of the healing powers of grapes in the time of ancient Greece. Today, modern science recognizes that the oily extract of grape seeds is a source of antioxidants and other biologically active compounds that may help keep you healthy and disease-free.
If you typically use oils such as vegetable oil and olive oil for your cooking, it's time to consider adding a different type with a slightly tastier name. The use of grape seed oil, which is made from the seeds of red grapes, can benefit your health in a number of ways. Even if you're anxious to get the benefits of this oil, you don't have to go to the length of drinking it.
Don't Try Drinking It


:Antioxidant Benefits
Grape seed oil is a healthy type of oil to include in your diet. It has a multitude of uses in the kitchen and can easily replace other oils with which you might typically cook. Although no health organizations caution against drinking grape seed oil, you can consume the oil in better ways. Despite its name, this type of oil doesn't have a taste reminiscent of grapes, and its thick, oily texture isn't enjoyable to swallow.


Grape seeds are separated from grapes when they are pressed to make wine. Grinding the seeds releases an oil that contains a number of fatty compounds, some proteins, vitamin E and plant compounds called flavonoids. One class of flavonoids, oligomeric proanthocyanidins, or OPCs, contains especially potent antioxidants that may have significant health benefits. Antioxidants stabilize free radicals, which are unstable chemicals formed in your body as byproducts of digestion or after you are exposed to environmental toxins. Free radicals can speed aging and raise your risk of cancer and other diseases. When stabilized by antioxidants, they become harmless and your body can easily dispose of them.
:Keep Your Oil Intake Low


Cardiovascular Benefits
Part of the reason you shouldn't try to drink grape seed oil is because, taste and texture aside, you don't need to consume a significant amount of this oil. Provided you get at least 30 minutes of physical activity, ChooseMyPlate.gov cautions against consuming oil in excess of 7 teaspoons per day. Women between 19 and 30 years of age should consume up to 6 teaspoons of oil daily and 5 teaspoons after the age of 30. For men, an intake of 7 teaspoons per day is appropriate between the ages of 19 and 30. After 30, men should limit their oil intake to 6 teaspoons.


Many research studies suggest that grape seed oil has cardiovascular benefits. For example, a study published in "Journal of Medicine" found that subjects with high cholesterol who consumed grape seed extract along with chromium for two months had lowered cholesterol levels, compared to groups who consumed a placebo or the extract or chromium alone. In a review of clinical trials published in "Journal of the American Dietetic Association," the authors concluded that compounds in grape seeds can significantly lower blood pressure and reduce heart rates in human subjects. A laboratory study published in "Mutation Research" identified several mechanisms through which OPCs in grape seeds improve heart function, leading the authors to suggest that grape seed oil might be a useful therapeutic tool.

Other Benefits
You don't have to resort to drinking grape seed oil because you can include it in your diet in several easier-to-stomach ways. This type of oil is ideal to use for frying because it has virtually no taste that could otherwise affect your food. It also won't smoke even at high temperatures. Grape seed oil can work in your deep fryer or frying pan. It can also serve as an ingredient in homemade salad dressings.


Memorial Sloan-Kettering Cancer Center reports that compounds in grape seeds may have anti-cancer properties, citing a study in "Cancer Epidemiology, Biomarkers and Prevention" in which many supplements were evaluated for their possible use in preventing cancer. The authors concluded that grape seed extracts may lower the risk of developing certain cancers of the circulatory system. Cancer Center experts also report that grape seed extracts inhibit growth of cultured cancer cells in the laboratory and could increase the anti-cancer effects of some chemotherapy drugs. According to the University of Maryland Medical Center, grape seed oil can also speed recovery from swelling or edema caused by surgery or an injury, and it may improve symptoms of venous insufficiency, a disorder of the veins in your legs.
:A Healthy Source of Vitamin E


How To Use It
Grape seed oil is notable for its high concentration of vitamin E. One tablespoon of the oil has 3.9 milligrams of this vitamin. The same amount of corn, peanut or olive oil has just 2.1 milligrams of vitamin E. Your recommended dietary allowance of vitamin E is 15 milligrams per day. In your body, vitamin E serves as an antioxidant, improves your immune system and contributes to cell function.


Grape seed oil is available at some food markets as bottled oil or from health food stores as oil or extract in capsules, tablets or liquid. For maximum health benefit, choose oil or extract standardized for its content of OPCs. Generally considered safe and without significant side effects, grape seed oil or extract might cause mild nausea, stomach upset or diarrhea in some people and might interact with certain medications, including blood-thinners or drugs broken down in your liver. Do not consume grape seed extract if you are pregnant or breast-feeding. Talk to your doctor before consuming the oil or extract to decide what is best for your situation.
