Sensitivity notes

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 soy milk

Soy milk is high FODMAP and high in nickel, which surprises people who assume any dairy-free milk is gentle. The FODMAP load comes from galacto-oligosaccharides (GOS), so how the milk is made matters: soy milk pressed from whole soybeans is high FODMAP, while soy milk built from soy protein isolate tests low FODMAP and is usually fine. Histamine and lactose are not the issue here.

Watch for

  • High FODMAP through GOS, the same bean-family carbs that make legumes hard to digest, so a full glass can bring bloating, gas and cramps
  • The label decides it: 'whole soybeans' means high FODMAP, 'soy protein isolate' means low FODMAP and usually tolerated
  • High in nickel, one of the more nickel-rich plant milks, which can matter if you get systemic nickel allergy flares like dyshidrotic eczema or itching
  • Rated pro-inflammatory and not AIP or EoE friendly, since soy is one of the common elimination-diet proteins
