Cultural taboos around food are powerful – could vegans change ours?

As campaigns such as Veganuary become more popular could the way westerners categorise what's edible start to shift?

Yesterday marked the end of "Veganuary", the campaign to encourage people to try a vegan lifestyle for a month. Year on year the trend has grown. Might those one-month vegans change the habits of the rest of us - by changing what an animal is?

Vegans shun all animal-derived products - meat, fish and leather obviously, but also eggs, dairy products, honey and wool. Beers refined using isinglass (derived from fish guts) are out, as would the new UK 5 and 10 notes, if they could be. The term itself was coined back in 1944, bringing together the start and end of the word VEGetariAN, as the next step on.
