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.
