3. Say yes to pineapple for a happy mouth
Here’s something to smile about: This tangy treat does wonders for your mouth. Thanks to high levels of vitamin C and an enyzme called bromelain that comes from its core, just a small serving of pineapple can help fight gum disease, stimulate digestion and minimize plaque. (A recent Indian study found that brushing with a bromelain-extract toothpaste significantly reduced stains on teeth.) Even better, pineapple (as well as citrus fruits) has been linked to sweeter breath and better body odour.
