The NHS is at crisis point. Despite the diet books, the fitness videos, the health bloggers, in 2016, Public Health England estimated that Illness associated with lifestyle costs the NHS £11 billion every year.

But are we missing something obvious? Could we bring down the cost to the taxpayer, reduce pressure on the health system, with simple advice on what we should eat and drink when we go to see our GP?

A growing group of medical professionals think so. Meet the doctors demanding better training on food and nutrition for students at medical school; Dr Rangan Chatterjee (BBC One's Doctor In The House), Dr Michael Mosley, (BBC Two's Trust Me I'm a Doctor) and Dr Rupy Aujla (The Doctor's Kitchen) and many more, all believe that if tomorrow's doctors were taught more about nutrition and diet, it could have a transformative effect on the health of the UK.

In this programme Professor Sumantra Ray, doctor and founding chair of NNEdPro Global Centre for Nutrition and Health describes a decade of work which could soon see widespread training for trainee doctors. And Sheila Dillon meets the students taking the conversation about food and health into their own hands.
