Future foods: What will we be eating in 20 years' time?

Insects, or mini-livestock as they could become known, will become a staple of our diet, says Gaye.

It’s a win-win situation. Insects provide as much nutritional value as ordinary meat and are a great source of protein, according to researchers at Wageningen University in the Netherlands. They also cost less to raise than cattle, consume less water and do not have much of a carbon footprint. Plus, there are an estimated 1,400 species that are edible to man.

Gaye is not talking about bushtucker-style witchetty grubs arriving on a plate near you. Insect burgers and sausages are likely to resemble their meat counterparts.

“Things like crickets and grasshoppers will be ground down and used as an ingredient in things like burgers.”
