Option a calcium absorption is decreased by phytic acid, oxalic acid, and tannins because Foods high in oxalic acid also impede the absorption of calcium .
Pregnancy, lactation, and growth are additional factors that affect calcium absorption from the food. These conditions boost calcium absorption. The fact that oxalate can bind to minerals in the gut and stop the body from absorbing them is one of the main health problems associated with it. For instance, spinach contains a lot of oxalate, which hinders the body from absorbing a lot of the calcium. High oxalate concentrations increase the likelihood that it may bind to calcium and produce kidney stones.

The majority of kidney stones are caused by oxalates, which also contribute to the body's depletion of nutrients.
