National Eat a Peach Day - August 22 Whether you like them fresh and juicy out of hand or baked into a luscious dessert, peaches are a summer must. Enjoy them while you still can! The peach, like many fruit, contains many useful vitamins, minerals and nutrients. The seed, though, is less good for you, being toxic with the chance of producing the dangerous hydrogen cyanide gas. So, eat a peach, but don’t eat the stone.
