 Dark green leafy vegetables are the most nutrient-dense food on planet Earth. For weeks, six of the Daily Dozen challenge is your challenge. They add two servings of dark green leafy, cruciferous or not, to your day. Greens are win-win. The nitrates and the potassium work together, nitrates from green leafy vegetables, are converted to nitric oxide in your body, and potassium increases nitric oxide release, which can both improve our artery function within hours of consuming greens. Add some greens just about anything—any meal or snack, smoothie, soups, stews, pasta dishes, sandwiches—if getting two cups of raw leafy greens is intimidating to you, well then just chop it up and cook it down. Remember to use the hashtag Daily Dozen Challenge for all your posts. We will share a wrap-up of each week's challenge post to our stories on Friday.
