Edgar Anstey and Arthur Elton’s sponsored documentary on Britain’s malnutrition crisis, blending expert testimony (Julian Huxley, J. B. Orr, A. V. Hill/Gowland Hopkins) with school-meal scenes and simple charts to link low income to poor diets and argue for “protective” foods and public provision. Commissioned by the gas industry, it plays like a brisk scientific lecture-film that helped push nutrition into public debate.
