OLIVE OIL: Let’s all use more of it!
Olive oil is a top source of oleic acid, an omega-9 fatty acid that is converted during digestion to oleoylethanolamide (OEA), a hormone that helps keep brain cells healthy. In a new study from the University of California, Irvine, rodents fed OEA were better able to remember how to perform two tasks than those that didn’t eat it. Researchers hypothesize that OEA signals the part of the brain responsible for turning short-term memories into long-term ones. “OEA seems to be part of the glue that makes memories stick,” says Daniele Piomelli, PhD, a professor of pharmacology and biological chemistry at the university.
Serving tip: Drizzle on roasted veggies or salad, or mix with crushed garlic and a pinch of salt and spread on toasted whole grain bread. Or blend equal parts olive oil, balsamic vinegar, and water with a squeeze of lemon and use as a dip for crisp veggies like radishes or cucumber. Healthy daily amount: 2 Tbsp.
