Melon and other similar fruits have a number of interesting effects on the body. The high intake of antioxidants and vitamins is accompanied by high levels of fiber. This can help to optimize digestion and regulate organ function, including the kidneys. Melon, in particular, is known to benefit people suffering from ascites, the accumulation of excess fluid in the abdomen. By starting each day with melon, or drinking concentrated melon juice, ascites patients reported a rapid reduction in stored fluid within their abdomen.
