Coconut water

Coconut water is notable for nickel, salicylate, FODMAPs and fructose. Clear on histamine, tyramine, sucrose, lactose, oligosaccharides, sorbitol, oxalates and gluten.

Yes — coconut water is high in nickel. Coconut water carries the mineral load the palm draws up, nickel included. It is drunk by the glass rather than the spoonful, which is what puts it here. Coconut is one of the few plant foods measured for this axis in its own right: the level follows a survey of essential and non-essential metals across COCONUT PRODUCTS, which is why the water, the flesh and the milk do not all read the same here.

Coconut water contains moderate levels of salicylate. Coconut is mild on this axis and the water is the most dilute part of it, but it is drunk in large volumes, which is what brings it up to moderate. Neither study publishes a value for this particular drink.

Coconut water contains moderate levels of FODMAPs. Coconut water carries sorbitol, which is why a drink that is mostly water lands here. The threshold is about half a glass, and it is easy to pass because it is marketed as hydration rather than as a sugary drink.

Coconut water contains only low levels of fructose. Coconut water carries a small amount of sugar, mostly sucrose and glucose rather than free fructose. It is drunk by the glass, which is what puts it on the scale at all. Amounts vary by brand and recipe, so always check the label of the exact product.
