Ecological Study of the Impact of National Food Availability on the Epidemiology of National Cardiovascular Mortality

An ecological study investigates the relationship between national food supply and cardiovascular disease (CVD) mortality across high, upper-middle, and lower-middle-income countries. Using WHO and FAO data, the study applies linear and multivariate regression analyses to explore associations between dietary variables and CVD mortality. The findings reveal a significant positive association between animal food sources and CVD mortality, while vegetable food variables show no significant correlation. The study concludes that increasing animal food supply contributes to higher national CVD mortality, offering insights for public food policy adjustments
