5 A Day is any of various national campaigns in developed countries such as the United States, the United Kingdom, France, and Germany, to encourage the consumption of at least five portions of fruit and vegetables each day, following a recommendation by the World Health Organization that individuals consume "a minimum of 400g of fruit and vegetables per day (excluding potatoes and other starchy tubers)." A meta-analysis of the many studies of this issue was published in 2017 and found that consumption of double the minimum recommendation – 800g or 10 a day – provided an increased protection against all forms of mortality. In some places, people are being encouraged to aim for not just five portions a day, but seven.
