Prison inmates are better fed than National Health Service (NHS) patients in the UK, according to new research.

Researchers from Bournemouth University found that about 40% of patients admitted to NHS hospitals were already malnourished and this did not tend to improve during their stay in hospital, BBC News reports.

Prisoners are given healthier and more nutritious food than patients, where they don’t add salt and there is relatively little frying of food, researchers said.
