The Claim
Higher meat intake is associated with longer life expectancy, and this association persists in populations with high vegetarian prevalence, indicating that the proportion of vegetarians in a country does not account for the observed relationship.
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 countries where many people eat vegetarian diets, those who eat more meat still tend to live longer, and this pattern cannot be explained by how many vegetarians live there.
See the scientific wording
The association between meat intake and life expectancy remains significant even in populations with high vegetarian prevalence, suggesting that the observed pattern is not explained by the proportion of vegetarians in a country.
Meat provides essential amino acids, iron, zinc, and B vitamins that the body uses to build proteins, make red blood cells, and power energy production. These nutrients help maintain muscle mass, support immune function, and keep organs working efficiently, which allows the body to sustain health and function longer.
What the research says
1 studyEven in countries where lots of people don’t eat meat, those who do eat more meat still tend to live longer, and this isn’t just because meat-eating countries are richer or healthier overall—the study shows meat intake is still linked to longer life even after accounting for those factors.
