People who grow their own fruit and veg waste less food and eat more healthily, says research

The rising cost of living is making it harder for people, especially those on lower incomes (who often have poorer diets), to afford to eat healthily. Despite this, households in the UK continue to waste a shocking amount of food – including around 68kg of fruit and vegetables each year.

Food waste is not only damaging to your pocket, it’s also bad for the environment too. Globally, 1.3 billion tonnes of food are wasted every year, generating about 8% of the world’s greenhouse gas emissions. These emissions arise from unused food at all stages of the food supply chain, from production to decomposition.

However, our recent study revealed that those who grow their own food in gardens and allotments waste an average of just 3.4kg of fruits and vegetables – 95% less than the UK average. These households adopted various practices to minimise food waste, including preserving or giving away their excess produce.

There has been renewed interest in growing fresh produce in gardens, community gardens and allotments in the UK and elsewhere in recent years. But the available supply of allotments is not enough to meet increasing demand.

Allocating more land for household fruit and vegetable production could make a significant contribution to the availability of fresh produce for urban residents.

Research has shown that using a mere 10% of the available space in the English city of Sheffield for food cultivation could supply enough fruit and vegetables to meet the needs of 15% of the city’s population. And more people growing their own food could also reduce waste.

Our study involved 197 households in the UK that grow their own food. We asked them to
