The world is producing more fruit and
vegetables – but still not enough. In
2000 world production totalled just 306
grams per person per day. By 2017 this
had risen to 390 grams (FAO, 2020) –
but this includes non-edible portions
such as the core and peel, as well as
loss and waste, which are often very
high. WHO recommends that people
should eat at least 400 grams of fruit
and vegetables a day (Mason-D’Croz et
