Question

BlackTom AI · Accepted Answer

In this question, we are asked about the absorption-inhibiting effect of oxalic acid, a component of fiber.
Option 1: protein. Oxalic acid does not primarily interfere with protein absorption; its effects are not related to binding or reducing amino acid or protein uptake.
Option 2: vitamin A. There is no well-established mechanism by which oxalic acid directly reduces absorption of vitamin A; the interference is not typically described for fat-soluble vitamins like A in relation to oxalates.
Option 3: calcium. This is the correct mechanism: oxalic acid can bind calcium to form calcium oxalate, a poorly soluble compound, which reduces calcium absorption in the gut and can contribute to calcium bioavailability concerns.
Option 4: thiamin. Oxalic acid’s known interactions do not involve thiamin (vitamin B1); there is no common claim that oxalates inhibit thiamin absorption via complexation.
Overall, the inhibitory effect of oxalic acid is specifically linked to calcium by forming insoluble calcium oxalate, which lowers calcium bioavailability rather than affecting the absorption of proteins, vitamins like A, or thiamin.
