Why was it a no-go? For years peanut butter was seen as something that was just for kids’ sandwiches and was too fattening for health conscious adults to include in their diet. Why they were wrong: Whilst it is true that peanut butter is chock full of calories and is high in fat, in the right doses (around a tablespoon or two a day) the health benefits outweigh the risk to your waistline. Peanut butter is a source of healthy protein which is important for helping to repair muscles. It also contains potassium, healthy fats, fibre and vitamin E. So feel free to add some peanut butter to your toast in the morning to keep you feeling full until lunchtime. Or have a cut up apple with two tablespoons of peanut butter as a super healthy mid-afternoon snack.
