Need to focus? Put down the coffee and go green. Yes, you could load up on fighter-pilot-strength attention pills, but the right combination of fruit and veg could give you improved focus, concentration and mental clarity – without the unpleasant comedown. 

Use nutritionist Scott Baptie’s smoothie to turn over a new leaf. With its antioxidant-rich ingredients, this smoothie might just give your focus a boost. At any rate it’s a good way to increase your intake of plant varieties – in an article explaining prebiotics, the Gut Health Doctor recommends aiming for 30 different types per week.
