It’s melon season in Russia, where stands hawking watermelons and torpedo melons pop up all over Moscow at this time of year. The fruits’ popularity goes deeper than their suitability as a sweet, refreshing snack–Russians believe that melons are the ultimate Master Cleanse, flushing out the body’s systems, and making up for all the vodka you drank this summer. Folklore holds that melons are good for everything from your kidneys, joints, and bowels, to your sexual performance. So it’s no wonder that this time of year, some Russians exist on a diet of nothing but melons, and many rush to consume them as often as possible. You don’t even need a spoonful of sugar with that medicine.
