Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread

Serving size, prep, and portion notes for baking powder
The question people actually type is whether baking powder is gluten free, and the honest answer is: usually yes, but it depends on the tin. Baking powder is three things blended together, sodium bicarbonate, a dry powdered acid such as monocalcium phosphate or sodium acid pyrophosphate, and a starch buffer that keeps the two from reacting in the packet. That starch is almost always cornstarch, which is why the standard product grades A for gluten, but a minority of brands use wheat starch instead, so coeliacs should read the ingredient line rather than assume. On every other trigger it is a quiet ingredient: A for histamine and histamine liberation, lactose, dairy protein, sulfites, nitrites, nickel, glutamates and nightshades, with all four FODMAP groups rated clean as well.
Watch for
The starch buffer is the only part worth checking. Cornstarch is the norm and is what the A gluten grade reflects, but wheat starch shows up in some brands, particularly outside the US. Certified gluten-free tins exist for exactly this reason / If you avoid corn rather than gluten, the same buffer is your problem in reverse. Corn-free baking powders exist, or you can mix your own from cream of tartar and baking soda / Double-acting powders built on sodium aluminium sulfate leave a faint metallic edge that some palates pick up in pancakes and yellow cakes. Aluminium-free versions use phosphate acids instead. That is a taste issue, not a graded trigger / It is still a sodium salt blend. A teaspoon runs around 400 mg of sodium, less than the same spoon of pure baking soda but not nothing if you are counting salt / Potency fades once the tin is opened. Stale powder gives a poor rise, cooks compensate by doubling it, and the extra unreacted acid and alkali is what makes the crumb taste chemical
