Why lactose food checker matters
Lactose is the natural sugar in milk and dairy products. People with lactose intolerance lack sufficient lactase enzyme to digest it, leading to bloating, gas, and digestive discomfort after consuming dairy.
- Try lactose-free dairy products - they're real dairy with lactase added
- Hard aged cheeses are naturally lower in lactose
- Lactase enzyme supplements can help when eating dairy
- Yogurt and kefir may be better tolerated due to probiotics
- Your tolerance level is personal - some can handle small amounts

What to know about fructose
Fructose is the sugar at the centre of the condition called fructose malabsorption. Pure crystalline fructose is all free fructose with no glucose to help carry it across the gut wall, so it is the textbook excess-fructose FODMAP. When the small intestine cannot keep up, the rest ferments in the colon and causes bloating, gas, cramping and diarrhoea.
Watch for
- The definitional excess-fructose FODMAP: with no glucose alongside it, absorption fails easily and symptoms follow
- A frequent trigger for bloating, wind, cramping and diarrhoea in anyone with fructose malabsorption, even in small amounts
- Poorly suited to SIBO, where the extra fermentable sugar feeds bacterial overgrowth
