My Day on a Plate: Jo Whiley, radio DJ 7pm Interview over, I nip into my studio to go on air, fuelled by tea and some biscuits from the packet we always have on hand. 8.30pm Race to the radio theatre, mid-show, to introduce Paul on stage. 10:30pm Arrive home where my husband is waiting with a vodka and lemonade and some kettle chips. Jo's schedule makes it understandable that she's a grazer but she's choosing fatty, salty and sugary snacks. Pasta or couscous salads would provide longer-lasting energy and more nutrients than the mayo-based sarnie and crisps at lunch. Unsalted nuts, dried apricots or fruit bread would be a lot more sustaining than biscuits.
