                                Despite persistent online claims, the idea that fruit is 'H3O' is a fundamental chemical misunderstanding. Fruits are not composed of the hydronium ion ($H_3O^+$), but are indeed excellent sources of hydration, containing high percentages of regular water ($H_2O$) along with beneficial nutrients and electrolytes.
