Jujube is the fruit of the jujube tree, holding a high place in Chinese food and tradition, often a symbol of being 'restorative'. But to understand it, first separate fresh from dried — the two differ greatly.

Fresh jujube is crisp, sweet, and juicy, with fairly high vitamin C. But what most of us eat is the sun-dried red date: drying pulls out water and concentrates sugar, while heat-sensitive vitamin C is largely lost. So though both are 'dates', the dried one is essentially a 'concentrated sweet dried fruit' — the same story as grapes becoming raisins (grapes).

This island's task is to separate jujube's real nutrition (next scene) from its most famous claim — 'red dates build blood' (third scene). The conclusion may differ from what many of us heard growing up.
