Poor, rural societies which ate high-quality foods bought locally had the best diet and health in mid-Victorian Britain, a new report has revealed.
The healthiest regions, measured by low mortality rates, were often the most isolated.
In those areas, people would have ingested plenty of locally-produced potatoes, whole grains, veggies, fish and milk.
There were also fewer demises there from pulmonary tuberculosis.
This indicates people had better diets, the researchers writing in JRSM Open suggest.
They received the most nutritious diets were enjoyed in isolated, rural areas of England, the two sides of the strait and islands of Scotland and the west of Ireland – which was at that time part of the United Kingdom of Great Britain and Ireland.
