The Claim
The association between a healthy diet score and reduced cardiovascular disease and mortality is significantly stronger in low-income countries than in high-income countries.
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 low-income countries, people who eat healthier diets have a stronger reduction in heart disease and death compared to people in high-income countries who eat similarly healthy diets.
See the scientific wording
The association between a healthy diet score and reduced cardiovascular disease and mortality is significantly stronger in low-income countries than in high-income countries, suggesting that increasing intake of protective foods may have greater public health impact where consumption is lowest.
When people eat very little healthy food, their bodies lack key nutrients that keep blood vessels healthy and calm inflammation. Adding those foods restores the nutrients, which directly lowers inflammation in blood vessels and improves how well they expand and contract, reducing the chance of heart attacks and death.
What the research says
1 studyStudy: Diet, cardiovascular disease, and mortality in 80 countries
In countries where people eat very little healthy food like fruits, nuts, and dairy, adding just a little more of these foods is linked to much bigger drops in heart disease and death than in countries where people already eat plenty. The study found this pattern across 80 countries.
