Flaxseeds are the richest plant-based source of omega
fatty acids and are easy to find in
health food stores. Buy the seeds, grind them in
a coffee grinder, and sprinkle them on cereal or toast or add them to a smoothie. If you're in a rush, buy a bottle of flaxseed oil and drizzle 1 tablespoon a day over salad, popcorn, or a baked potato. (Just don't cook with flaxseed oil; the heat destroys its beneficial nutrients.
