Lags’ food in prisons tastes nice – because it is served on blue plates.
The colour of crockery has been used in jails for some time.
But now research has revealed that eating meals from blue ones can increase the consumer’s satisfaction.

The trial for the study took place at hospitals.
Patients had all their meals served on white plates for the first four weeks and blue crockery for the next four.
The research took place at Royal South Hants Hospital, in Southampton.
The results gathered by the NHS exposed that 14% more of the blue plates were returned empty.
Producing an impressive 20% less food waste.
A second trial took place at the Northampton General Hospital NHS Trust, as reported by Need To Know.

During the study, the number of meals returned uneaten on white plates ranged between 25% and 30%.
This fell to 10% when the blue plates were introduced.
The conclusion stated that the food looked more ‘appetising’ on a blue background.
It was particularly popular for patients with dementia or visual impairments.
According to NHS chiefs 20% of all hospital meals are wasted, with bosses now looking to extend the scheme to improve nutrition and reduce food waste.
Blue plastic plates, bowls and mugs are standard in public-sector prisons across England and Wales, according to Inside Time.
The Prison Service has been approached for comment.
