What to know about water
Plain water is the baseline safe drink: no histamine, no FODMAPs, no salicylate, no caffeine, nothing to react to. If water seems to bother you, the trigger is almost always an additive, not the water. Tonic water contains quinine and sugar, flavoured and vitamin waters add sweeteners and citric acid, and sparkling or carbonated water can bloat a sensitive or reflux-prone gut. Still water itself is as clean as a drink gets.
Watch for
- Tonic water is not plain water: it contains quinine and added sugar, so a reaction to tonic is not a reaction to water
- Flavoured and vitamin waters add sweeteners, acids and colourings, any of which can be the real trigger
- Sparkling and carbonated water can cause bloating or reflux for some, from the carbonation rather than any chemical trigger
