What Happens to Your Body When You Eat Grapeseed Oil Regularly

Grapeseed oil often flies under the radar of household cooking oils. This is a shame, considering grapeseed oil offers many potential health benefits, such as combating inflammation, boosting cardiovascular health and reducing cancer risk.1

But what happens to your body when you eat grapeseed oil regularly? To find out, we delved into the research and spoke with a registered dietitian. Read on to uncover grapeseed oil’s nutrition profile, the health benefits of incorporating it into your weekly menu, whether there are potential red flags to look out for and tips for enjoying it as part of a healthy, well-balanced diet.

Health Benefits of Grapeseed Oil

Promotes Heart Health

Grapeseed oil is rich in polyunsaturated fats (PUFAs), specifically omega-6 fatty acids, which can be beneficial for heart health.3 Harris-Pincus says, “The PUFAs in grapeseed oil can help lower LDL (often called “bad”) cholesterol when you substitute it for saturated fats in your diet.”4 Grapeseed oil also contains compounds like linoleic acid, which may help reduce inflammation and boost overall cardiovascular health.2

May Reduce Chronic Disease Risk

Grapeseed oil contains antioxidants like vitamin E and proanthocyanidins. These antioxidants can help protect cells from damage caused by free radicals, which are unstable molecules that can lead to oxidative stress and various chronic diseases.1 Other antioxidants found in grapeseed oil can also help reduce inflammation. “Grapeseed oil has antioxidants like polyphenols such as resveratrol and quercetin that may offer anti-inflammatory benefits,” says Harris-Pincus.

Supports Better Skin Health

The antioxidants and omega-6 fatty acids in grapeseed oil can also help improve your skin. Vitamin E, in particular, is known for its moisturizing and wound-healing benefits.5 Since grapeseed oil is rich in vitamin E, applying grapeseed oil topically or eating it regularly may help improve skin hydration, elasticity and overall appearance. Additionally, Harris-Pincus says grapeseed oil’s vitamin E content may offer anti-aging benefits for skin.

May Help Regulate Blood Sugar

Some studies suggest that grapeseed oil may help improve insulin sensitivity and reduce blood sugar levels.6 While more research is needed to confirm these benefits, incorporating grapeseed oil into a balanced diet may benefit those with diabetes or prediabetes.

Grapeseed Oil Nutrition

One tablespoon (14 milliliters) of grapeseed oil contains the following, per the USDA:

Calories: 120

Total Carbohydrates: 0 g

Dietary Fiber: 0 g

Total Sugars: 0 g

Protein: 0 g

Total Fat: 14 g

Saturated Fat: 0 g

Sodium: 0 mg

Vitamin E: 4 mg (27% Daily Value)

Cons to Consider

One potential drawback of frequent grapeseed oil consumption is the high omega-6 fatty acid content. While omega-6 fats are essential for optimal health, excessive consumption may lead to an imbalance in the omega-3 to omega-6 ratio over time, which research shows can increase the risk of inflammation and other health issues.7

Grapeseed oil is high in calories and fat, so consuming large quantities may lead to weight gain. “Grapeseed oil is a concentrated source of calories, the same as any oil,” explains Harris-Pincus. “With 120 calories per tablespoon (all from fat), it’s important to be aware of portion sizes when using any oil.”

Is Grapeseed Oil Safe for Everyone to Eat?

While grapeseed oil is generally safe for most people when enjoyed in moderation as part of a balanced diet, regularly consuming it may result in inflammation or adverse effects for those with grapeseed oil allergies. “Grapeseed oil is likely safe for anyone who does not have an allergy to grapes or a medical disorder requiring a limit on fat intake,” says Harris-Pincus. “Make sure to store it away from heat in a dark place to protect the oil from oxidizing.”

4 Ways to Enjoy Grapeseed Oil

In Salad Dressings

Instead of using a store-bought salad dressing, combine grapeseed oil with vinegar or citrus juice, herbs and spices for a simple, flavorful homemade dressing. Try our Grapeseed Oil Caraway Vinaigrette as a refreshing addition to your salads.

For Roasting Vegetables

Grapeseed oil’s high smoke point makes it a fantastic option for roasting veggies at high temperatures. Toss your favorite veggies in grapeseed oil, season with salt, pepper and herbs, and roast until tender and caramelized. The result is deliciously crispy vegetables with a hint of nutty flavor, like our Sheet-Pan Roasted Root Vegetables.

In Baking

Substitute grapeseed oil for some of the butter or other oils to reduce saturated fat content in baking recipes. Grapeseed oil adds moisture and richness to baked goods without overpowering other flavors. Try using it in cakes, muffins or a baked oatmeal recipe like our Peach Baked Oatmeal.

As a Marinade

Grapeseed oil can be used as a marinade base for meats, poultry, seafood or tofu. Combine it with herbs, spices and acidic ingredients like vinegar or citrus juice to tenderize and flavor your protein before cooking. Give our Spicy Herb Sauce a try and it may become part of your regular rotation.
