A top cardiovascular researcher warns that current global heart health guidelines are too one-size-fits-all, overlooking regional differences and social determinants of health, as revealed by the multi-country PURE study, which highlights disparities in physical activity, diet, and environmental factors affecting heart disease risk worldwide.
A new study based on the international Prospective Urban and Rural Epidemiological (PURE) study and data from five other international trials suggests that diets containing higher amounts of certain food categories, including fruit, vegetables, nuts, legumes, fish, and whole-fat dairy, may be protective against cardiovascular disease and premature death. The study challenges the preference for low-fat or no-fat dairy foods in healthy-diet recommendations and highlights the need for updated guidelines and policies that focus on increasing the consumption of protective foods. The findings also emphasize the importance of context-specific policies to improve the availability and affordability of healthy foods, especially in lower-income countries.
