Chia Seeds
Although chia seeds have an abundance of plant omega-3s, our bodies are not so great at absorbing the specific nutrients they offer. There isn't enough extensive research to say much about the good and the bad, but chia seeds do have the soluble fiber vital for avoiding a visit to the gastroenterologist. Just remember to eat them in moderation so the bathroom doesn't become your next best friend.
