Grapeseed oil is rich in antioxidants and polyunsaturated fats and is associated with various health benefits, including reducing inflammation and oxidative stress. Additionally, a study on rats found that grape seed oil may enhance cognition in Alzheimer’s disease. However, it is commonly processed with harsh chemical solvents such as hexane and high heats, which may result in the formation of harmful compounds and cause the oil to lose many of its naturally occurring nutrients. Even though it is valued for withstanding high heats, it is rich in polyunsaturated fats that may oxidize during cooking and form harmful compounds.
