Abertay University students are urging people to live a bug's life as part of efforts to prevent global famine.

Masters students have developed "bug biscuits", using the bodies of ground-up crickets baked with cocoa powder and a hint of orange.

The programme aims to test what it would take for Scots to accept insects as a real source of nutrition.

Student Anja Sieghartsleitner says western attitudes towards food must change if the world is to meet the food demands of a growing population.

She added: "Insects are a lot more sustainable than other sources of meat like beef, chicken and pork.

"They use a lot less land and water and you can eat the whole insect, not just part of the animal. You may not want to eat a whole cricket but if it's hidden away in flour, or in a biscuit, you may be more likely to accept it.

"If we are seeking to feed nine billion people by 2050 then we have to change our eating behaviour as the amount of meat we eat is not sustainable."
