What can reduce the absorption?

  1. High animal protein diets appears to increase calcium losses
  2. A sedentary lifestyle causes calcium to dissolve out of the bones and into the blood. On the contrary, regular exercise strengthens the bones by encouraging bone calcification
  3. High phosphorus intake, which would destabilize the balance Calcium/Phosphorus
  4. A number of substances can inhibit the absorption of calcium:
    • Phytic acid, which is found in raw cereals and legumes
    • Oxalic acid, which is found in chocolate, spinach, broccoli and rhubarb combines with calcium to form insoluble compounds which cause kidney stones
  5. Saturated fats: a meal high in fats can form insoluble calcium soaps
  6. Too much fiber may interfere with calcium's absorption
  7. Stress
  8. Sodium
  9. Caffeine
  10. Gastro-intestinal problems
