Secrets of Your Supermarket Shop - Season 5

Return of the consumer strand. Alexis Conran lifts the lid on the nation's vitamin supplement habit, while Angellica Bell investigates the truth about the carbon footprint of favourite sandwich fillings. And the team reveals how to cook a Sunday roast while saving on energy bills.

Angellica Bell tests kitchen gadgets, asking which are worth buying and which simply gather dust. With rising petrol prices, Alexis Conran finds out how people can drive more efficiently, and how meat-free manufacturers are creating foods that taste and smell just like meat.

Alexis Conran investigates how supermarket clothing matches up to the high street for quality and cost. Angellica Bell investigates healthy offal and how it can halve the cost of a typical dinner, while the team also discovers the surprising truth about the carbon footprint of supermarket asparagus.

Angellica Bell investigates why many people overlook ethically sourced lesser-known great value fish in favour of better-known and fashionable favourites. The team also examines sun cream to find out whether cheaper supermarket sunscreens keep us safe.

The team finds out if fabric conditioner is worth shelling out for in every wash, or if we could all save a little money (and perhaps the planet) by using it less. Angellica Bell investigates if simple ingredient swaps make for cheaper meals. Angellica is in the kitchen testing fishfingers, crackers and pasta to see if she can persuade one family to swap some of their favourite brands for lesser known and cheaper versions.
