Lower the risk of chronic diseases like diabetes, cancer, and heart disease

Boost your gut health by feeding different types of beneficial gut bacteria
-
Help maintain a healthy weight through nutrient-dense, low-calorie options

Add berries to your breakfast — oatmeal, yogurt, or smoothies.

Use leafy greens as a base for salads and bowls.
-
Incorporate roasted or steamed vegetables of different colors into dinner.
