Miracle Fruit Makes Sour Sweet

Here's an odd one for you. If you're not fond of sour patch kids or bitter lemon, you may want to check out these tablets made from a tropical fruit native to West Africa. A pink-colored tablet, they contain a sweet-inducing protein called miraculin which will make anything sour that you eat taste sweet for up to 2 hours.

This is because the protein miraculin firmly binds to sweet receptor cells in a person's tongue when sour substances are present. The protein then transmits a false message to the brain, resulting in a strong, sweet taste.
