Sensitivity notes

Why dairy proteins food checker matters

Dairy proteins (casein and whey) can cause reactions in people with milk protein allergy or intolerance. This is different from lactose intolerance and can cause both digestive and systemic symptoms.

  • Dairy protein allergy requires complete dairy avoidance
  • Casein and whey are the main proteins to avoid
  • 'Non-dairy' products may still contain casein
  • Ghee may be tolerated as proteins are removed
  • This is different from lactose intolerance - treatment differs

Ingredient notes

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
