First, the combination of flavors is terrific. Pineapple is a terrific companion for tropical fruits like mangoes, bananas, and citrus like oranges and grapefruits because scientifically they share similar aromas. Both are rich in vitamins (like vitamin C), minerals, antioxidants, and enzymes (pineapple). You can tell by their bright colors, that's the beta carotene. So eating them together is a power-packed way to get a healthy dose of something delicious and a boost to your health as well.
