Food attitudes
Browsing through my late grandad's copy of Furneaux's Human Physiology (1940 edition), I found something interesting in the chapter on Food. First the author goes through the "Standard Forms of Food": milk, eggs, meat and bread. Then he briefly goes through the "Adjuncts to Food" - see the picture. He hardly considers fruit and vegetables to be food at all, which perhaps goes some way to explaining why, 70 years later, we still turn our noses up at them.
