Watermelon

As its name suggests watermelon is an excellent way to hydrate in the morning. Whats less well known is this juicy fruit is among the best sources of lycopenea nutrient found in red fruits and vegetables thats important for vision heart health and cancer prevention. Best of all watermelon contains just 40 calories per cup landing it on lists of so called negative calorie foods that supposedly burn more calories during digestion than they add in. (Actually its a bit more complicated than that but thats no reason to not eat watermelon!)
