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.

Sian Williams and Stefan Gates get to the heart of supermarket food - the ingredients - finding out why what appears on the front of the packet may not always be the same as what's inside. Stefan highlights the use of cheap ingredients by comparing pizzas made with real cheese and processed cheese. Can a consummate pizza chef tell the difference? Sian looks at the amount of fat in ready meals and Stefan reveals how ice-cream companies use the cheapest secret ingredient of them all - air.
