Teachers Neil and Angela have two daughters with very different eating habits. 17-year-old Ffion is a disabled swimmer, born with one arm. She trains twice a day and hopes to represent Britain at the 2020 Paralympics. Ffion is a meat-loving athlete, whereas 16-year-old Alice is a committed vegetarian who usually ends up eating a different microwave meal from the rest of the family. Add to that Angela's love of pre-prepared, premium-brand products, and their shopping bill has become out of control.

Newlyweds Mandy and Adie have four children between them. Brand-loving Mandy admits to having 'champagne taste with a lemonade income' - she never says no to the kids' food requests and, as a result, they go through 70 bags of branded crisps a week. Adie, however, thinks budget versions are just as good. Mandy also relies on convenience microwave meals whereas Adie likes to cook from scratch, leaving this couple completely at loggerheads.

Meet the Hoyland family. Dad Derek, who has coeliac disease, has not eaten the same meal as his family for nearly six years, living off salads to avoid any gluten in his diet. Mum Clair is brand obsessed, filling the trolley with frozen convenience food, diet-ready meals and litres of bottled water every week, spending over double the national average for a family of four. Their two children, Connor and Amy, long to sit down as a family and all eat the same meal, but Clair's fear of gluten-free cooking means she cooks three separate meals every day.
