Feeling sluggish after the New Year's festivities? This will perk you up - incredible info on diet and how it affects your focus: This year, I wanted to focus on creating a podcast for you right at the start of 2018 that focuses on optimum nutrition for body and brain. Because let's be honest, a few too many mince pies have probably been consumed over the last month. (Side note: Americans don't have mince pies, which is a shame.) And today's guest knows how that can have an impact in surprising areas.   Steven Masley is one of the world's top experts in this area. He's a bestselling author and TV Doctor in the States, and he knows his stuff. His new book, The Better Brain Solution, is out tomorrow and I heartily recommend a cheeky pre-order as he is one of the top people in the field. It focuses on the link between body, brain and what we eat.
