Sensitivity notes
Why fodmaps food checker matters
FODMAPs are fermentable carbohydrates that can cause digestive distress in sensitive individuals. They include fructose, lactose, fructans, galactans, and polyols. These sugars are poorly absorbed in the small intestine and ferment in the colon, potentially causing bloating, gas, and discomfort.
- Start with a 2-6 week elimination phase, removing all high-FODMAP foods
- Keep a detailed food and symptom diary to track your reactions
- Reintroduce one FODMAP group at a time to identify your specific triggers
- Remember that threshold varies - you may tolerate small amounts
- Work with a dietitian trained in the low-FODMAP diet for best results

What to know about yam
True yam, the starchy Dioscorea tuber sold in African, Caribbean and Asian markets, grades high in oxalate. That is not incidental: raw yam contains needle-shaped calcium oxalate crystals, which is exactly why peeling one bare-handed can leave your skin itching. It is otherwise clean on histamine, gluten, lactose, nickel and nightshades, with a moderate polyol grade that can matter on a low FODMAP plan. It is also graded pro-inflammatory as a dense starchy staple.
Watch for
- High in oxalate, driven by the calcium oxalate raphides in the tuber, so it is a food to portion rather than pile on if you form calcium oxalate kidney stones
- Raw yam sap irritates skin, which is why cooks glove up or peel under water.Yam should always be cooked thoroughly, never eaten raw
- Moderate polyol content, the sugar alcohol group behind bloating and osmotic diarrhoea, so a large serve can be an issue even though yam is clean on fructans, GOS and fructose
- Graded pro-inflammatory as a dense starchy staple, which is a dietary pattern note rather than a chemical sensitivity
- Yam and sweet potato are different plants and are often mislabelled in supermarkets, so check what you actually bought before you trust a lookup
