Diet, lifestyle and biological determinants of health and chronic diseases: the EPIC-Norfolk Prospective population study

Twenty-five thousand men and women in Norfolk have been logging their diets, exercise habits, and health for decades, and researchers are now using that data to figure out what keeps people healthy as they age. This matters because the population is getting older, and the big question is how to prevent the chronic diseases that often come with age—heart disease, stroke, cancer, arthritis, diabetes, respiratory disease, and osteoporosis—rather than just treating them after they appear. Most studies focus on a single disease; this one tracks a large group of people over time to see which combinations of diet, lifestyle, and biology predict who stays well and who doesn't. If the research succeeds, it could change how doctors and public health officials advise people on what to eat and how to move to avoid disability in later life. The study is also measuring new biological markers in blood, including genetic profiles, to understand disease processes better. That deeper knowledge could eventually point toward more targeted treatments. For now, the work is fundamental: it is building a long-term picture of what healthy ageing actually looks like in a real population, which is the foundation for any future prevention strategy.
