The Claim

Higher national meat consumption is statistically associated with higher life expectancy at birth across 175 countries, even after adjusting for caloric intake, urbanization, obesity, education, and GDP per capita.

In plain English

Countries with higher meat consumption tend to have higher life expectancy at birth, even when accounting for differences in calorie intake, urbanization, obesity rates, education, and income.

See the scientific wording

Higher national meat consumption is statistically associated with higher life expectancy at birth across 175 countries, even after adjusting for caloric intake, urbanization, obesity, education, and GDP per capita, suggesting that meat intake may be a population-level predictor of longevity independent of socioeconomic and lifestyle confounders.

Why this might work

Eating more meat provides more complete proteins and essential nutrients like iron, zinc, and vitamin B12, which help cells repair damage, make energy efficiently, and maintain healthy tissues, allowing the body to function longer without failure.
