Sensitivity notes
Why histamine food checker matters
Histamine is a compound naturally present in many foods, especially aged, fermented, or preserved items. In sensitive individuals, excess histamine can cause headaches, flushing, hives, digestive issues, and other symptoms. Your body normally breaks down histamine, but some people have reduced capacity to do so.
- Focus on fresh foods - histamine builds up as food ages
- Cook and eat meals fresh; avoid leftovers sitting more than 24 hours
- Be cautious with fermented foods, aged cheeses, and cured meats
- Consider that stress and hormones can affect your histamine tolerance
- Some antihistamines or DAO supplements may help (consult your doctor)

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
