Sesame oil is, as you probably guessed, derived from sesame seeds. It has a distinct nutty taste and is considered a healthier alternative to vegetable oils, mostly because of its anti-inflammatory, antioxidant, and antimicrobial properties (via Healthline).
A study published in 2015 in the journal, Acta Medica Iranica, assessed the effect of sesame seeds on inflammation and oxidative stress in people with osteoarthritis (OA). Of the 50 study participants, 25 were given 40 grams of sesame seeds daily and the other 25 were given a daily placebo powder, along with their regular treatments. After two months, researchers found was those who ate the sesame seeds had significant decreases in inflammatory proteins. The study’s authors confirmed sesame seeds could be a safe, effective, and complementary treatment for people with OA.
According to Healthline, it is best to use unrefined sesame oil at low to medium heat. The site further added that refined sesame oil can be used for deep frying and stir-frying. Toasted sesame oil, on the other hand, is much more delicate and can be best used for dressings and marinades.
