Flax seeds offer a dose of plant-based omega-3s, just like chia seeds. However, whole flax seeds can pass through the body undigested so if you want to reap the benefits, you have to grind them before you eat them. You can either buy ground flax or stick the seeds in a coffee grinder, then add them to most dishes for a nutrient boost. If it’s ground finely enough, you may not even know it’s there!

Mix ground flax into yogurt, oatmeal or cereal, or combine it with whole-wheat flour for pancakes, muffins and other baked goods. You can also blend it into energizing fruit smoothies like my Memory-Boosting Berry Smoothie or stir it into soups and sauces. For a vegan venture, try using ground flax (or ground chia, for that matter) to replace eggs in just about any recipe that calls for them: Swap each egg for 2 tablespoons ground seeds and 2 tablespoons water, and brace yourself for a delicious discovery.
