What to know about lucuma

Almost nobody outside Peru meets lucuma as a fruit. Fresh Pouteria lucuma is dry, dense and crumbly with a flavour somewhere between maple, caramel and sweet potato, and in the rest of the world it arrives as a beige powder sold as a natural sweetener. Its trigger row is quiet: A for histamine content, tyramine, nickel, gluten, lactose, dairy protein, free glutamates, sulfites, nitrites and nightshades, with mild B grades for histamine liberation, salicylates and oxalates. The FODMAP columns are unrated, and that gap matters more for lucuma than for most fruits because of the form it is sold in. Powder is dehydrated pulp, so a heaped spoonful represents several times its own weight in fresh fruit, and anything untested gets concentrated along with the flavour. Two other things are worth saying plainly. Lucuma powder is not a calorie free or carbohydrate free sweetener: it is dried fruit, mostly sugar and starch, and the low glycaemic marketing around it rests on very little published evidence. And the way most people actually eat lucuma, as Peru favourite ice cream flavour, brings its own trigger profile from the dairy rather than from the fruit.
