Grapeseed Oil: Benefits & Side Effects

Grapeseed oil is rich in monounsaturated fatty acids like omega-6 and omega-9. When consumed in moderation, these fatty acids can provide anti-inflammatory health benefits. On the other hand, too much of these fatty acids can be bad news. Side effects can include increased inflammation levels, hormone imbalance, and weight gain. But in moderation, grapeseed oil benefits include lower cholesterol levels, healthy skin, and healthy hair.

Grapeseed Oil Benefits

1. High in Omega-6

Grapeseed oil benefits the body by providing it omega-6 fatty acids and linoleic acid. Linoleic acid or LA is converted to gamma-linolenic acid or GLA through digestion. GLA has a protective effect on the body. For example, it helps lower cholesterol levels and inflammation. Grapeseed oil benefits also include the ability to aid in weight loss and lower insulin resistance. (1)

2. Good Source of Vitamin E

Grapeseed oil also benefits the body by providing it with a healthy source of Vitamin E. That's important because Vitamin E works as a powerful antioxidant to boost the immune system. Compared to olive oil, grapeseed oil benefits the body with double the amount of Vitamin E. (2)

3. Zero Trans Fat

Well, by now you've heard that trans fats are no good, and grapeseed oil benefits include zero trans fats. Research has shown that a diet high in trans fats is linked to numerous health issues. Fast food, packaged snacks, and fried foods are often full of trans fats. (3)

4. Benefits Skin and Hair

Thanks to the Vitamin E it contains, grapeseed oil also benefits the skin and hair. Vitamin E provides natural moisture, and the fatty acids in the oil work to prevent dryness and irritation. Furthermore, this versatile oil helps protect the skin from sun damage. (4)

5. It Has a High Smoke Point

Another grapeseed oil benefit is its high smoke point. Compared to olive oil and other vegetable oils, grapeseed oil has a significantly higher smoke point and can be used in cooking. In fact, many vegetable oils oxidize easily and become toxic when used in cooking, but grapeseed oil can be used for sauteing and cooking at moderate temperatures.

Grapeseed Oil Side Effects

Grapeseed oil side effects may occur due to a diet too high in omega-6 fatty acids. Possible grapeseed oil side effects include:

1. Increased Inflammation

Due to the omega-6 content, grapeseed oil side effects can include increased inflammation levels in the body. An imbalance of omega-6 fatty acids can increase the risk of heart disease and other inflammatory conditions.

2. Higher Cholesterol Levels

Consuming too much grapeseed oil may increase cholesterol levels. The oil is high in polyunsaturated fats. When polyunsaturated fats become oxidized, the body is unable to metabolize and use cholesterol properly. This can increase the rise of clogged arteries and heart disease, so avoid cooking with it at high temperatures.

3. Hormonal Imbalance

Increased inflammation levels can lead to a hormonal imbalance. High levels of omega-6 fatty acids can interfere with the body's ability to produce different hormones, which can lead to problems with thyroid activity.

4. Obesity and Weight Gain

Increased inflammation levels and a hormonal imbalance can lead to weight gain and obesity. If the thyroid isn't functioning properly, then the metabolism may also suffer.
