The Claim

Carbohydrate crop intake is not significantly associated with life expectancy at the population level after adjustment for meat intake and other confounding variables.

In plain English

Across countries, differences in life expectancy are not explained by how much people eat from carbohydrate crops like rice, wheat, or corn, once differences in meat consumption and other factors are accounted for.

See the scientific wording

Carbohydrate crop intake shows no significant association with life expectancy at the population level after adjusting for meat intake and other confounders, suggesting that energy from plant-based staples alone does not explain variations in longevity across nations.

Why this might work

Eating more rice, bread, or sugar does not change how the body ages because the body only needs a certain amount of energy from carbs to function, and extra carbs don't trigger any biological changes that slow down or speed up aging.

  1. Study: Total Meat Intake is Associated with Life Expectancy: A Cross-Sectional Data Analysis of 175 Contemporary Populations

    The study found that how much rice, bread, or sugar a country eats doesn’t help predict how long people live there — even when you account for how much meat they eat and other factors like income and education. So, eating more carbs doesn’t make people live longer, according to this data.
