A good quality peanut butter and a few oatcakes is all you really need in your desk drawer come 4pm. The oatcakes offer slow-release carbohydrate so they're much better for energy levels than bread, while Whole Earth's peanut butter
is packed with protein. Add a couple of slices of banana if you're really hungry. Or, try 1 apple, sliced, with 1tbsp peanut butter: A potent combo of fibre, antioxidants and protein.
How much? 1tsp on an oatcake.
