We are a nation of snackers and we tend to get a whopping 25% of our daily calories from our snacks. But surprisingly, snacking isn\\u2019t necessarily bad for our health. Dr Sarah Berry at Kings College London explores a pragmatic approach to snacking, and tells Michael how what you snack on and when you snack has the greatest impact on your health. You don\\u2019t have to stop snacking - just snack smartly by swapping in some less-processed options. Our volunteer Denise, a hotel facilities manager from Liverpool, tries to reap the benefits of better snacks.
