Walnut Oil: A Plant Source of Omega-3s
Walnut oil is rich in alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid. While many plant oils contain mostly omega-6s, walnut oil stands out as a natural source of ALA, which the body can use as a building block for healthy cell membranes. In the kitchen and in supplements, it’s valued for its light, nutty flavor and its healthy unsaturated fat profile.
