There maybe a debate about the healthiness or otherwise of wartime diets, but to claim that the UK current diet of over 50% processed foods, lots of industrially produced meat and dairy products is the optimum diet for good health and much better than any other available is a not something many would agree with. Mediterranean countries have a healthy diet with olive oil, fresh fruit and veg, smaller portions of meat and far less reliance on ready meals, processed burgers etc. Less than 12% of food bought in Italy and Greece is processed, people in those countries aren't "starving" either.
