12. Pineapples
One of the many wonders of pineapples is their astonishing power of regeneration. You’ll just need a couple of pineapple leaves, and there you go! In only three years you’ll find your own pineapple tree in the garden. Moreover, one pineapple contains 131 % of vitamin C. That directly implies that while eating your bare-peeled pineapple, you’ll be safe from flu, cold and cough. And remember, always prefer a fresh over canned pineapple!
