Just one tablespoon (15 ml) contains an impressive 7,200 mg of omega-3 ALA, so you’re set for the day. Other excellent alternatives include ground flaxseed, hempseed, walnuts, and almonds. Olives, olive oil, avocados, and soybeans are also excellent sources, as are broccoli, sweet peas, and many leafy greens. Algae and seaweed are important sources of omega-3s for people on vegan or vegetarian diets, or anyone who doesn’t eat fish, as they are one of the few plant foods containing preassembled DHA and EPA.
