Overview
About Amaranth Grain
Amaranth grain is the poppy-seed-sized pseudocereal, not a true cereal, sold for porridge, popped rajgira and gluten-free flour blends.
It is genuinely gluten free (graded A) and the reason it sells so well, but it is not the blank-slate grain the packaging implies. Our data grades it D for oxalate, C for total FODMAPs with fructans and GOS both at C, C for nickel and C for SIBO fermentability. None of those is severe on its own. Together they explain why amaranth porridge can sit badly with people who assumed a gluten-free grain would be automatically gentle, and why it deserves a portion cap rather than a free pass.

How Amaranth Grain scores
Watch for
What trips people up
- Graded D for oxalate. Amaranth grain is one of the higher-oxalate gluten-free options, so if you are restricting oxalate for kidney stones it is a poor default replacement for wheat
- Total FODMAPs graded C with fructans at C and GOS at C. Three moderate grades stacking in one food is why a large bowl of amaranth porridge behaves worse than the individual grades suggest
- Nickel graded C. Whole seeds and pseudocereals are recognised nickel carriers, which is relevant if you have systemic nickel allergy and are tracking dyshidrotic eczema or flare patterns rather than gut symptoms
- Graded C for SIBO fermentability, so it is a middling choice on a low-fermentation protocol. White rice and rice noodles are graded A and B respectively on the same measure
- Truly gluten free at A, and unlike oat products there is no shared-crop issue, though flour blends that combine amaranth with other grains still need a label check

FAQ
Common questions about Amaranth Grain
Is amaranth grain high in oxalate?
Our data grades amaranth grain D for oxalate, which is the high band. That makes it a questionable swap if you are on an oxalate-restricted diet for calcium oxalate kidney stones, even though it is an excellent swap for gluten. Rice and corn tortillas are both graded A for oxalate and cover the same starch role.
Is amaranth grain low FODMAP?
It is moderate rather than low. Amaranth grain is graded C for total FODMAPs, with fructans at C and galacto-oligosaccharides at C. Small servings are often fine and larger ones frequently are not, which is the classic signature of a portion-dependent food. If you are still in the elimination phase, rice is graded A across every FODMAP subgroup.
Is amaranth gluten free?
Yes. Amaranth is a pseudocereal from the Amaranthus plant, botanically unrelated to wheat, barley and rye, and it is graded A for gluten. It is safe for coeliac disease in its pure form. Multigrain flour blends that include amaranth are the only real risk, so read the full ingredient list rather than trusting the front of the pack.
Is amaranth high in nickel?
It is graded C, which is the moderate band. That puts it in the same general territory as most whole seeds and legumes. For people with systemic nickel allergy syndrome, moderate-nickel foods usually matter as cumulative daily load rather than as single-meal triggers, so the useful thing to log is how many nickel-carrying foods stacked up that day.
