Hypothesis
What is the association between protein intake and the risk of mortality from all causes, cardiovascular diseases, and cancer?
Conclusion
Higher plant protein intake is associated with a reduced risk of all-cause and cardiovascular disease mortality.
Supporting Evidence
- Total protein intake was not associated with all-cause, cardiovascular, and cancer mortality.
- Animal protein intake was not associated with all-cause, cardiovascular, and cancer mortality.
- Plant protein intake was inversely associated with the risk of all-cause mortality.
- Plant protein intake was inversely associated with the risk of cardiovascular disease mortality.
Takeaway
Eating more plant-based protein can help you live longer and reduce the risk of heart disease.
Methodology
A meta-analysis of prospective cohort studies was conducted, using random effects models to calculate pooled effect sizes and confidence intervals.
