Building a healthier Britain. Part 1, Heart disease.

The first in a four-part series in which Richard Hannaford looks at how since the 1950s doctors have continuously researched people's health and lifestyle, leading to epidemiological studies, the results of which we can perhaps now begin to assess. This part focuses on heart disease, in particular the findings of the Seven Countries Study which started in the 1950s and looked at the differing rate of heart attacks across the world. The study had a huge impact on the incidence of heart disease in Finland and still inspires health initiatives today, such as the 'Have a Heart, Paisley' one in Scotland.
