Episode 4

Last year, one story about food and health dominated the headlines and it was the claim that processed meat causes cancer. In this episode, Alice Roberts investigates the chemical that's causing the problem and asks how worried should we be about eating meat? Also do aphrodisiacs actually work? Forget oysters, champagne and strawberries as there's no evidence they work but research does point to a couple of substances that could claim to be aphrodisiacs. Tom Kerridge reveals the store cupboard essentials that as a professional chef he won't be without and he answers a cry for help from a viewer whose risotto always ends up a disaster. And our consumer journalist Sean Fletcher pulls apart the ingredients in cheap and expensive mayonnaise to find out what we're really paying for.
