Serving size, prep, and portion notes for hfcs
High-fructose corn syrup is a top FODMAP trigger precisely because it is everywhere: soda, sweetened drinks, sauces, cereals, bread and processed snacks. It carries more fructose than glucose, so it delivers excess fructose in exactly the foods where you are least likely to notice it. For anyone with fructose malabsorption or IBS, HFCS is often the hidden reason a packaged food causes bloating and diarrhoea.
Watch for
High in excess fructose and rated a top overall FODMAP source, so it triggers bloating, gas and diarrhoea in fructose malabsorbers / Hidden across processed foods and drinks, which makes accidental doses easy and hard to trace back to the culprit / A poor fit for SIBO, DASH and Mediterranean eating, and pro-inflammatory as a refined added sugar
