Don't chop up carrots before you boil them - if you do, you're losing most of the cancer-fighting properties of the vegetable.
Instead, say researchers, cook the carrot whole, and chop it up only after it's been boiled. That way, the vegetable retains more of its cancer-fighting compound falcarinol.
It also seems the carrot tastes better if it's not chopped up before cooking. It keeps more of its natural sugars, and was preferred in a blind tasting, say researchers from Newcastle University.
