In June the government announced plans to launch a review of hospital food following the listeria outbreak that led to the deaths of six people in NHS hospitals.
Philip Shelley, former head of the Hospital Caterers Association said there will be a ‘root and branch’ review. The report will explore the increasing amount of in-house catering as well as how hospitals can use more fresh produce and less frozen food.
Leith will act as an advisor to improve the standards of hospital food. She commented: "Millions of pounds are wasted in hospitals with food ending up in the bin, unpalatable food being the main complaint.
"I'm delighted that at long last Downing Street and the Department of Health have decided to do something about it.
"A hospital meal should be a small highlight, a little pleasure and comfort, and it should help, not hinder, the patient's recovery.
Prime Minister Boris Johnson, added: "Guaranteeing hospitals serve nutritional, tasty and fresh meals will not only aid patient recovery, but also fuel staff and visitors as they care for loved ones and the vulnerable."
A 2013 report found that more than £50 million had been wasted on failed schemes to improve the quality of hospital food.
Rachel Power, chief executive of the Patients Association, said: "We are pleased to see a full review of hospital food being undertaken and hope it leads to more nutritious and nourishing meals to help patients with their recovery.
"People should be able to look forward to their meals, particularly when dealing with the pressures and worries that a stay in hospital can bring, even with the best of care."
