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 yam bean

The yam bean is neither a yam nor a bean you eat, and both halves of that name mislead in ways that matter. It is Pachyrhizus erosus, a vine in the pea family whose swollen root is the only food part: crisp, wet, faintly sweet, eaten raw in Mexico and across Southeast Asia. The pods and mature seeds that give it the bean half of its name contain rotenone and are genuinely toxic, historically used as a fish poison and a garden insecticide. The root itself is clean on the sensitivity chemistry, grading A for galacto-oligosaccharides, lactose, gluten, dairy protein, caffeine, sulfites and nitrites, with histamine, salicylate, oxalate, tyramine and nickel all mild at B. The one real gut caveat is fructans, which grade D here, alongside a D for total FODMAPs, so the trigger to watch is fructan load rather than anything chemical.

Watch for

  • Fructans grade D and total FODMAPs grade D, so the storage sugars in the root are the thing to log.Galacto-oligosaccharides, polyols and excess fructose are all clean, which is unusual for something in the pea family
  • Only the root is food.The pods, the mature seeds and the vine carry rotenone, and eating the seeds is a real poisoning risk rather than a folk warning. If you buy it whole or grow it, discard everything except the tuber
  • It travels under a confusing pile of names: yam bean, Mexican turnip, sengkuang, bengkoang, sa kot, jicama.Log it under one name consistently or your own history will not add up
  • Nothing else scores high.Histamine, salicylate, oxalate, tyramine, nickel and free glutamate all sit at B, so if you react hard and fast to this root, suspect what it was dressed with, typically chilli, lime and salt
