Calcium Absorption

Calcium Absorption

Write the factors interfering with the absorption of calcium.
Answer.

Factors Which Interfere with Calcium Absorption

Calcium Absorption: How It Works and Its Importance

• Phytates present in cereals form insoluble calcium salts and inhibit calcium absorption
• Oxalates present in vegetables like cabbage and spinach form insoluble calcium salts and inhibit calcium absorption
• High content of dietary phosphorus results in the formation of insoluble calcium phosphate and inhibits calcium absorption
• Free fatty acids inhibit calcium absorption by reacting with calcium to form insoluble calcium soap. This is particularly observed when fat absorption is impaired
• High pH (alkaline conditions) inhibits calcium absorption
• High content of dietary fiber interferes with calcium absorption
• A high content of magnesium in the diet decreases calcium absorption
• High content of iron in the diet inhibits calcium absorption.
