Sir, - During the second world war, food rationing in Britain meant that meat became almost unobtainable with the result that the average diet during that period and well into the 1950s became semi-vegetarian. From research carried out during that period, we now know that Britain under a system of rationing, where the diet consisted mainly of vegetables and cereals, with almost no meat and limited amounts of sugar and white floor, attained far higher standards of health than ever before or since. - Yours, etc.,
