Although a few sources of grape seed oil exist in the United States, most available for purchase are imported from France, Switzerland and Italy, according to Epicurious. A plant-based food product, grape seed oil is an omega-3 rich food source, as stated by the American Academy of Neurology in a 2007 press release.

The U.S. Department of Agriculture's National Nutrient Database says 1 tsp. of grape seed oil provides 40 calories. In addition to calories, the food product provides 1.3 mg vitamin E, 0.4 g saturated fat, 0.7 g monounsaturated fat and 3.1 g polyunsaturated fat. There are 8 mg of phytosterols in a 1-tsp. portion of grape seed oil and no cholesterol.
Expert Insight
The Nov. 13, 2007 edition of "Neurology," the official journal of the American Academy of Neurology, used grape seed oil as an omega-3 fatty acid-rich food source in a study. The conclusion of the study cited the frequent consumption of fruits, vegetables and omega-3 rich oils may decrease the risk of dementia and Alzheimer's disease.
Uses
Grape seed oil may be the oil of choice when sauteing food because it has a high smoking point. Grape seed oil can also have a distinctive flavor. It may be preferred for use in salad dressings for this reason.
