Sensitivity notes

Why oxalates food checker matters

Oxalates are compounds found in many plant foods that can bind with calcium to form crystals. High oxalate intake may contribute to kidney stones in susceptible individuals and can cause other symptoms in those with oxalate sensitivity.

  • Stay well-hydrated to help prevent oxalate crystal formation
  • Pair high-oxalate foods with calcium-rich foods to bind oxalates
  • Cooking and boiling can reduce oxalate content in some foods
  • Spread oxalate intake throughout the day rather than one large dose
  • Consider probiotics - some gut bacteria break down oxalates

What to know about green apple

Green apples such as Granny Smith taste sharp and less sweet, so people assume they are the gentle choice, but on FODMAPs they are anything but. They are high in excess fructose and in sorbitol, the same two sugars that make any apple a top FODMAP trigger, which is why a whole green apple often brings on bloating, wind and cramps in a sensitive gut.

Watch for

  • High in excess fructose, with more fructose than glucose, which many people absorb only partially
  • High in sorbitol, a sugar alcohol that ferments and pulls water into the gut, stacking on top of the fructose
  • Being tart and less sweet does not make it lower FODMAP; the fermentable sugars are still there, so it is a poor pick for a sensitive gut or for SIBO
  • Carries a little nickel and is mildly histamine-liberating, minor next to the FODMAP load but worth a note for very sensitive people
