A New Zealand scientist says diets of the future will have to adapt as global population grows from 7 billion to 10 billion over the next 35 years.
Professor Paul Moughan from Massey University's Riddet Institute has just been picked to join a think tank in Germany in June to help tackle world hunger and malnourishment.
He says he and the three other international experts chosen will research why 800 million people world wide are chronically malnourished and how to improve future global diets as the climate changes.
"As some large economies become wealthier people demand higher protein diets. So the nature of the diet is also going to change over time. And when we talk about malnutrition you know we think of under nutrition but there's also malnutrition in the sense of people eating too much of the wrong food."
Professor Moughan says the report they published will help shape governmental and United Nations policies.
