Does a plant-based diet lower calcium requirements?

Recommendations for calcium requirements for the population are devised by panels of leading Nutrition and Scientific experts. They are based on age and life stage needs, but not dietary pattern choice. Therefore, the official dietary guidelines do not suggest lower calcium requirements for those following plant-based or vegan diets. In addition, the presence of oxalic, phytic and uronic acids in some plant foods decreases the bioavailability of calcium, as these compounds inhibit calcium absorption.
