Cooking with Grapeseed Oil: Is It Healthy?

Grapeseed oil’s popularity has surged in recent years. Touted for its health benefits due to rich polyunsaturated fat and vitamin E content, it’s often claimed to reduce blood cholesterol and heart disease risk.

This article examines the potential value in cooking with grapeseed oil by exploring why it brings nutrition and how you can benefit from that, separating fact from fiction.

What is grapeseed oil and how it’s made?

Grapeseed oil, derived from the seeds of grapes, a byproduct of the winemaking process, has become a valuable commodity in recent years. The transformation of these seeds from a discarded residue into a profitable oil is a remarkable example of modern technological and business innovation. 

Typically, this oil is extracted in factories where the seeds are crushed and solvents such as hexane are used, a common practice in the production of various vegetable oils like soybean oil. While there are concerns about the residual traces of such solvents and their potential health impacts, it’s important to note that the majority are removed during the refining process.

The process of cold-pressing presents an alternative method of extraction. Unlike the solvent-based method, cold-pressing involves mechanically pressing the seeds to extract the oil without the use of heat or chemical solvents. 

This method is particularly valued for its ability to preserve most of the oil’s natural nutrients and health benefits, making it a preferred choice for those seeking the most nutritious options. However, consumers should be aware that unless the oil’s packaging specifically mentions ‘cold-pressed’, it’s likely that the oil was extracted using chemical solvents like hexane. 

This underscores the importance of informed purchasing decisions in the context of health and environmental considerations.

Nutritional content of cold-pressed grapeseed oil

The nutritional appeal of grapeseed oil, especially when cold-pressed, lies in its rich content of vitamin E and polyunsaturated fats. In its composition, the fatty acid profile of cold-pressed grapeseed oil is notably beneficial:

  • Saturated Fat: 10%
  • Monounsaturated Fat: 16%
  • Polyunsaturated Fat: 70% (primarily omega-6, in the form of linoleic acid)

Cold-pressing helps in retaining these fatty acids in their most natural and beneficial form. Despite the predominant presence of omega-6 fatty acids, which have been speculated to contribute to inflammation, research suggests that linoleic acid, the primary omega-6 in grapeseed oil, does not exacerbate inflammatory markers.

Moreover, cold-pressed grapeseed oil is particularly valued for its substantial vitamin E content. This vitamin is known for its strong antioxidant properties, offering potential benefits for the nervous system and possibly playing a role in inhibiting tumor growth. 

However, it’s important to note that, aside from these significant nutrients, grapeseed oil, even when cold-pressed, is not a comprehensive source of other vitamins and minerals. This fact underscores the importance of a balanced diet to ensure a wide range of nutrients.

Health implications of consuming grapeseed oil

Grapeseed oil’s impact on health, particularly when consumed, has been the subject of some research, revealing a range of benefits. 

Studies suggest that grapeseed oil can help manage blood pressure, bolster the immune system, and may even play a role in preventing Alzheimer’s disease due to its anti-inflammatory properties. It’s also shown promise in speeding up wound healing, improving cholesterol profiles, and reducing swelling. 

Additionally, grapeseed oil might help in increasing testosterone levels and reducing scarring. Its potential in treating acne and as a hair moisturizer is also notable. However, it’s important to remember that some grapeseed oils may contain polycyclic aromatic hydrocarbons (PAHs), which are known carcinogens in animals. 

The extent of this issue and its impact on human health is still uncertain​.

Is cooking with grapeseed oil suitable?

Using cold-pressed grapeseed oil for cooking can be beneficial, albeit with certain considerations. While it’s not the optimal choice for frying due to its high polyunsaturated fat content, it excels in other cooking methods. 

Cold-pressed grapeseed oil is excellent for dressing salads, drizzling over finished dishes, and in low-heat cooking processes like sautéing, where its unique flavor and nutritional value, particularly its vitamin E and omega-6 fatty acid content, can be preserved. It adds a subtle, nutty taste to dishes, enhancing the overall flavor profile without overpowering the natural taste of the ingredients.

In summary, while grapeseed oil is rich in certain nutrients, cooking with grapeseed oil is best used in low-heat applications. It’s a versatile oil suitable for dressings and baking, providing many of the multiple supplementary benefits of the grape seeds at the table.
