Seitan

Why seitan is rated low

Seitan starts as wheat flour, which is why it surprises people, but the making of it is the point. The dough is kneaded and washed under water until the starch and the water soluble carbohydrates rinse away down the drain, leaving a springy mass of gluten protein behind. The rating here is estimated from that finished composition rather than from a weighed serving, so the portion guide is worded plainly and rates "Any typical portion" as low. The catch is that seitan almost never arrives plain. It is sold sitting in seasoned broth, braised as mock duck, marinated, or shaped into sausages and burgers, and those preparations are where onion and garlic come in. Worth saying clearly: low FODMAP is not the same as gluten free, and seitan is close to pure wheat gluten.

What changes your risk

• Serving size The guide covers "Any typical portion" and rates it low. Helpings well beyond a normal serving of protein are not something this data addresses.
• What washed away in the making The water soluble carbohydrates leave with the rinsing water, which is why the finished gluten sits where it does. Making it at home from vital wheat gluten starts from that same washed protein, so homemade and plain bought seitan tell the same story.
• The liquid it was packed or braised in Tubs and jars of seitan usually sit in a seasoned stock, and braised styles such as mock duck are cooked in a broth that typically begins with onion and garlic. The seitan soaks that liquid up, so draining it is not optional and reducing the packing liquid into a sauce undoes the point.
• Marinades, sausages and burgers Flavoured wheat protein products lead with onion powder and garlic powder, and some blend in chickpea, lentil or soy flour to bulk them out. Those additions change the product even though the seitan in it has not changed.
• The sauce you finish it in Hoisin, teriyaki, barbecue and most stir fry sauces are built on garlic, onion and honey. Garlic infused oil, ginger, chives, the green tops of spring onions and a pinch of asafoetida cover the same savoury depth.
• The rest of the plate Seitan adds nothing to the meal's total, but a wheat wrap or a couscous side does. Several low servings sharing one subgroup in a single sitting still add up.

What else works

Seitan holds its place well, and the other plain proteins sit alongside it: firm tofu, eggs, and plain meat, poultry and fish all fill the same slot without a portion to count. The category to be careful in is the rest of the meat alternatives aisle, because many of those patties, mince and sausages are built on chickpea, lentil or soy bean flour rather than wheat gluten, and they do not sit where seitan does. Flavoured mock meats, including seitan based ones, belong in that same careful group, since the seasoning rather than the protein is what moves them. Seitan is also not an option for anyone avoiding gluten, given what it is made of.

How to keep it low

Look for plain seitan sold as a block or strips and drain and pat it dry before cooking, rather than tipping the packing broth into the pan. Making your own from vital wheat gluten powder, water and your own seasoning is genuinely simple and puts you in charge of what goes in. Because plain seitan is bland by design, it rewards a hot pan: sear it hard in garlic infused oil so the edges crisp, then finish with ginger, chives and spring onion tops rather than a bought stir fry sauce. Shop by ingredients list rather than by the words on the front of the pack, since wheat protein products aimed at the flavour market are where the onion and garlic powder live.

Common questions

is seitan low fodmap if it's made from wheat

Yes. Washing the dough rinses the starch and water soluble carbohydrates out, and what is left is mostly gluten protein, which is why "Any typical portion" is rated low. The rating is an estimate from that finished composition.

how much seitan can i eat

The data is qualitative rather than in grams, and it rates "Any typical portion" as low, so a normal serving of it is not the number to watch. The marinade, packing broth and sauce are the parts worth checking.

is store bought seitan ok

Plain seitan, drained of its packing liquid, is straightforward. Pre marinated tubs, braised mock duck and seitan sausages are a different matter, because onion powder, garlic powder and garlic heavy braising stocks are standard in them.

is seitan gluten free

No, it is essentially pure wheat gluten. Low FODMAP and gluten free are two different things, and seitan is a clear example of a food that is one and not the other.
