Chasing Delicious made a cool little chart to visually represent different colored produce, what nutrients you can get from each group, and what they can do for your health. Check out their blog post for more in-depth knowledge of the benefits of each.
Truth is, you don’t need a chart. Just focus on switching up what you eat a lot. You’ve heard “eat the rainbow” before, and I’m always going on about a varied diet here on Eating Clean in the Dirty City. But the chart does serve as a friendly reminder of all the foods we’re not eating, even if we think we eat a varied diet. I, for one, could totally work more blue/purple veggies into my routine. You can purchase the chart as a print too–it would look lovely in the kitchen.
