http://www.bbc.co.uk/news/magazine-35595530 "People used to really like eating liver. In 1974 a typical household bought 36g of it per week. But not by 2014. Then the figure had fallen to just 3g - a 92% drop." I find it difficult to believe it possible to buy just 3g of liver, or even 36g for that matter, but leaving aside the nonsense weights, I accept the premise that fewer people eat liver now than in 1974. Supermarkets don't put a lot of it on their shelves and I am never certain whether our diets change as a consequence of customer preference or lack of supply. One thing I can say in confidence though, is that farmers haven't started breeding liver-less animals. What do you make of the Department for Environment, Food and Rural Affairs survey?
