6. Onion skins
Onion skins are packed with nutrients. They contain plant pigments that help lower blood pressure, reduce inflammation, and prevent clogged arteries. While the skin isn’t edible, you can easily make a broth from it or add it to soups and stews. This not only boosts the healthiness of your dish but also enhances its flavor—onion skins impart a rich taste. Just remember to remove them before serving.
