Gloria Hunniford, Angela Rippon and Julia Somerville round off the series investigating viewers' complaints about all things food and drink. They explore whether free-range eggs are really worth the extra cost, and reveal the unexpected levels of salt in some everyday products.

Also, how much can we trust the labels promising food is ethically produced?
