Watermelon is my favorite summer fruit. Watermelon has lots of vitamin and minerals and has more lycopene than tomatoes Lycopene is a powerful antioxidant that gives fruits and vegetables a pink or red color. Most people think tomato is king of lycopene and it has a lot, but watermelon is actually a more concentrated source. Watermelon is one of my favorite fruits to combine with kefir. It gets super bubbly and delicious!
