The Claim
Higher scores on the healthful Plant-Based Diet Index (hPDI) are weakly and positively associated with bone mineral apparent density (BMAD) in young adult women, but this association is no longer statistically significant after adjustment for overall diet quality, body fat, and physical activity.
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.
In young adult women, a diet higher in healthy plant-based foods shows a very small statistical link to higher bone mineral density, but this link is not meaningful once other factors like total diet quality, body fat, and physical activity are taken into account.
See the scientific wording
Higher scores on the healthful Plant-Based Diet Index (hPDI) are weakly and positively associated with bone mineral apparent density (BMAD) in young adult women (β = 0.077, P = 0.21), but this association disappears after adjusting for overall diet quality, body fat, and physical activity.
Eating more healthy plant foods provides nutrients that support bone building, but only if the body is also active and has the right amount of fat. Without enough movement or with too much or too little fat, the bones don’t get stronger, even with good nutrition.
What the research says
1 studyStudy: Plant-based dietary patterns and peak bone mass in healthy young adult women.
The study found that eating lots of healthy plant foods like fruits and veggies doesn’t really make young women’s bones stronger — any tiny link you might see goes away when you account for how active they are and how much body fat they have.
