If you are into nutty oils, here is another to add to your list: walnut. An even trendier oil than peanut, this one is made from nuts that have been dried and cold-pressed. The rich, nutty flavour works great as a salad dressing, or simply as a flavour enhancer, says Popeck. It's also a good source of Alpha-linoleic acid, which the body converts to the Omega-3 fatty acids EPA and DHA.These may help lower lipids, blood pressure and vascular inflammation, all of which support overall health. Whoo!
Pro tip: Walnut oil does not stand up to high heat due to its medium smoke-point, says Popeck. Because of this, stick to drizzles of it on salads or other veggies.
Other uses: You can make like Renaissance painters and use walnut oil as as a paint, paint thinner and brush cleaner. Woodworkers also use this oil in some finishes.
