Fifth of world’s food lost to over-eating and waste

March 9, 2017

A study has found that almost 20% of food available is lost through over-eating or waste. Globally, the population consumes approximately 10% more food than necessary and almost 9% is thrown away or left to spoil.

The team at the University of Edinburgh says that efforts to reduce the significant amount of food lost could improve global food security and help prevent damage to the environment. It will help ensure everyone has access to a safe, affordable and nutritious diet.

According to researchers, almost half of harvested crops (2.1 billion tonnes) are lost through over-consumption, consumer waste and inefficiencies in production processes. Increased demand for some foods, particularly meat and dairy products, would decrease the efficiency of the food system and make it difficult to feed the world’s expanding population in sustainable ways.

Meeting this demand could cause environmental harm through increased greenhouse gas emissions, depleted water supplies and loss of biodiversity. However, these trends could be reversed by encouraging people to eat fewer animal products, reduce waste and not exceed their nutritional needs.
