Festive sprout question.

YOUNG scientists are investigating the science of one of the key festive foods as they aim to answer the eternal Christmas dinner conundrum: why can't some people stand Brussels sprouts? A-level students are testing their DNA for the gene that is believed to determine whether a person likes their sprouts or not at the Eden Project in Cornwall.

The vegetables contain a bitter chemical similar to PTC (Phenylthiocarbamide) which tastes bitter to people that have a variation of a certain gene, a spokesman for the Eden Project said.

But those with a mutation on that gene do not taste the bitterness.

Around half of the world's population have the mutation, which scientists consider beneficial since people with it are more likely to enjoy eating Brussels sprouts, which are high in vitamin C and iron.

Alex Ledbrooke, Cornwall College science, technology, engineering and mathematics project manager, said: "Christmas dinner isn't usually associated with science. This hands-on project helps to do exactly that, as it explores why some people like and some hate Brussels sprouts."

The students are taking part in the tests as part of a national programme run by the UK Association for Science and Discovery Centres (ASDC) and supported by the Wellcome Trust - which aims to give young people hands-on experience with DNA.
