The Claim
Replacing 3% of daily energy intake from animal protein with plant protein is associated with a 10–12% reduction in all-cause and cardiovascular mortality over a 15-year period.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who replace 3% of their daily calories from animal protein with plant protein have a 10–12% lower risk of dying from any cause or from heart disease over 15 years.
See the scientific wording
Replacing 3% of daily energy from animal protein with plant protein is associated with a 10–12% reduction in all-cause and cardiovascular mortality over 15 years, suggesting a significant public health benefit from dietary protein source substitution.
When plant proteins reach the gut, they are not fully broken down and feed beneficial bacteria that produce short-chain fatty acids. These fatty acids strengthen the gut lining, prevent harmful substances from leaking into the bloodstream, reduce inflammation throughout the body, and lower blood pressure by blocking a key enzyme that narrows blood vessels. This combination of effects reduces the risk of heart disease and death from all causes.

1 studyStudy: Interactions Between Plant Proteins and Gut Microbiota as Determinants of Intestinal Health
This study found that if you swap a tiny bit of meat or dairy in your diet for beans or lentils, you’re 10–12% less likely to die from heart disease or other causes over 15 years — exactly what the claim says.
