Q. What do you mean by Oxalates?
Oxalates are widely distributed in plant foods mostly in the form of calcium salts. Oxalates are known to interfere with calcium absorption. High intake of oxalates increases their excretion in the urine, which in turn, may predispose the person to urinary stones. Rich sources of oxalates are green and leafy vegetables and some legumes like horsegram and kesari dhal (Lathyrus sativus).
