Energy drink

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

Yes — energy drink is high in histamine. Energy drinks are near the top of this axis because of what they stack rather than any one ingredient: caffeine at two or three times a cola's concentration, benzoate, azo colours and acidity regulators. Be precise about what that means - benzoate and the azo colours are documented in the PSEUDOALLERGEN literature, which is not the same as being documented liberators of histamine, and the caffeine claim is the weak one it is everywhere else. The elimination protocols remove all of these at once, and a can brings several of them cold and fast.

Yes — energy drink is high in salicylate. Energy drinks are high in salicylates through their flavourings and plant extracts — guarana and citrus among them — and the colourings they often carry are separate triggers on this same axis. Neither study publishes a value for this particular drink.

Energy drink contains moderate levels of sucrose. Energy drinks are sugar and caffeine in water, and a standard can carries as much sucrose as a cola. The sugar-free versions are a genuinely different product on this axis.

Energy drink contains only low levels of oxalates. Energy drinks carry little oxalate. Their relevance to stones is different and worth knowing: caffeine is mildly diuretic and sugar load matters, so the useful advice is about fluid rather than about oxalate. Amounts vary by brand and recipe, so always check the label of the exact product.
