Question

_______ present in cereals and green leafy vegetables interfere with absorption of calcium and phosphorus

Answer 1

Foods high in phosphorus can inhibit calcium absorption 
Hence, the answer is food high

Answer 2

Phytates and oxalates present in cereals and green leafy vegetables interfere with absorption of calcium and phosphorus.

Explanation:  

• Calcium and phosphorus are essential elements of the body. They are usually absorbed from the body from the stomach and gut.  

• They are absorbed in free form. But the phytates in cereals like wheat and oxalates in leafy green vegetables bind with calcium and phosphorus to form a complex compound.  

• This complex compound prevents the absorption of calcium and phosphorus from the gut. Hence these food should not be taken much in patients with hypocalcemia.
