The Claim
Inadequate calcium intake in vegan diets, resulting from the exclusion of dairy and low consumption of fortified alternatives, is associated with reduced bone mineral density and increased fracture risk, particularly when dietary calcium sources contain high levels of phytates and oxalates that limit bioavailability.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Vegan diets that lack dairy and fortified foods often provide insufficient calcium, leading to lower bone density and a higher rate of bone fractures when the calcium comes from sources high in phytates and oxalates.
See the scientific wording
Calcium intake is frequently inadequate in vegan diets due to exclusion of dairy and low consumption of fortified alternatives, contributing to lower bone mineral density and increased fracture risk, particularly when dietary sources are not bioavailable due to phytates and oxalates.
When not enough calcium is absorbed from food, bones cannot harden properly, making them weaker and more likely to break. Phytates and oxalates in plant foods block calcium from being absorbed, and without dairy or fortified foods, the body does not get enough calcium to maintain bone strength.
What the research says
1 studyVegans who don’t eat dairy or fortified foods may not get enough calcium, and this study shows they’re more likely to have weaker bones. But eating the right plant foods or taking supplements can fix it.
