Can cooking pasta, rice, or bread, and then cooling it down, actually make it healthier? Could yesterday’s leftovers affect your blood sugar differently than a freshly cooked meal, or is this just another nutrition “hack” invented by the internet? Melissa and Jam investigate starch, glucose, insulin, digestion, crystallization, and the surprising chemistry that happens while your food sits in the fridge. Plus, the whole thing somehow turns into a Lord of the Rings battle involving glucose, hobbits, and ents, because of course it does.
