Hypothesis
Is bone mineral density associated with the intake of soft drinks, fruits, and vegetables?
Conclusion
Frequent intake of soft drinks and rare intake of fruits and vegetables is negatively related to bone mineral density.
Supporting Evidence
- There was a consistent negative association between the Dietary Index and forearm bone mineral density.
- Colas and non-cola soft drinks were negatively associated with bone mineral density.
- The negative association persisted after adjusting for various covariates.
Takeaway
Drinking a lot of soft drinks and not eating enough fruits and vegetables can make your bones weaker.
Methodology
Bone mineral density was measured in a subsample of the Oslo Health Study, and a Dietary Index was calculated based on intake estimates of soft drinks and fruits/vegetables.
Potential Biases
Potential information bias from self-reported dietary intake and unmeasured confounding variables.
Limitations
The study is cross-sectional, which limits causal inferences, and self-reported dietary intake may introduce bias.
Participant Demographics
Participants included both men and women from various age groups, primarily residents of Oslo.
