I need to diversify my fruit & veggie. I eat about 5-6 crowns of broccoli a week and about a dozen bananas each week. I think broccoli is one of the more nutrient-rich vegetables.
As far as vegetables, I would recommend spinach, broccoli, tomatoes, and carrots or squash. That would be awesome if you ate all of those.
For fruits...bananas, blue berries, apples, and oranges. That would be a super mix also. But there are
so many other combinations & choices.
Really, the sky is the limit...make sure you get a good variety. That's the important thing. Every food has unique nutritional values, so eating a select few will not optimize your health.
