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
