Secrets of Your Supermarket Food

Sian Williams and Stefan Gates investigate whether fresh fruit and vegetables really are the best option, and whether some five-a-day favourites work out cheaper, tastier and more nutritious when frozen. They compare the sugar levels in fresh juice and smoothies, find out how much a typical family can save by buying frozen instead of fresh, and following the trail of a pea being picked being frozen. Plus, Sian asks whether the term `freshly baked' bread is misleading and there's a look at the safest way to store food in a fridge.
