THE 5-MINUTE DETOX -- one slice each of watermelon and honeydew melon, blend on high for 2 minutes. Honeydew melons are excellent at reducing water weight (thereby banishing bloat) and help to cleanse the kidneys. They are also loaded with Vitamin C, which boosts the immune system, destroys free radicals and makes skin glow. Watermelons contain fibre, lycopene, vitamin A and vitamin C, to cleanse the kidney, bladder, heart, stomach, colon and liver for full body rejuvenation.
