The 5-a-day slogan was invented in the late 1980s in America, before finding its way to the UK in the early 2000s. It was based on the idea that we need 400g of fruit and vegetables every day to reduce the risk of cancer, heart disease, stroke, and other diseases.

While it still rings true that getting enough fruit and vegetables in our diets is important, the thinking has changed - just like how we don't all need to do 10,000 steps every day or get eight hours of sleep.
