Some foods are delicious and some are good for you, watermelon is one of those foods that is both, packed full of nutrition and hydrates all at the same time. While many of us think of watermelon as a great snack option, when you tally up its nutritive value, you might consider making this all-star a feature player in your diet. Watermelons are an excellent source of several vitamins: vitamin A, which helps maintain eye health and is an antioxidant; vitamin C, which helps strengthen immunity, heal wounds, prevent cell damage, promote healthy teeth and gums; and vitamin B6, which helps brain function and helps convert protein to energy. Tomatoes have been highly touted as a great source for lycopene, a powerful antioxidant that helps fight heart disease and several types of cancer but, did you know that watermelon has the highest concentration of lycopene of any fresh fruit or vegetable around. It is a great source of potassium, which helps muscle and nerve function, helps maintain the body's proper electrolyte, and helps lower the risk of high blood pressure. I mean need I say more...well only that it also makes the perfect treat after a long day at the beach, so throw on your bikini and pack a few slices.
