Is pea milk vegan-compatible?

Serving size, prep, and portion notes for pea milk

Pea milk is built from yellow pea protein isolate rather than from ground whole peas, and that one manufacturing detail is why it grades clean where the legume behind it does not. Whole peas are high FODMAP and heavy in galacto-oligosaccharides; isolating the protein leaves the fermentable carbohydrate behind, so pea milk grades A on total FODMAPs and on every subgroup, A for histamine and histamine liberation, A for salicylate, oxalate, nickel, sulfites, nitrites, free glutamate and tyramine, and A for lactose, dairy protein and gluten. Nothing on the trigger panel is flagged. Its practical selling point is what it leaves out: no dairy, no nuts, no soy, no gluten, at roughly 8 g of protein per cup, which is dairy milk's own number and about eight times what almond milk delivers. That combination is genuinely rare, and it is why pea milk keeps turning up as the recommended swap on our pages for people juggling more than one restriction at once. The real caveats sit with the carton rather than the pea: it is still a legume, it carries a moderate lectin grade, it is out during an AIP elimination, and the sweetened and flavoured cartons are a different product from the unsweetened original these grades describe.
