Researchers at the University of Helsinki used computer modelling to find the optimal diet combination to meet nutritional needs, while also minimising global warming potential, water and land use.
They found that if people replaced meat and dairy with foods produced sustainably like insects, it could significantly reduce all environmental impacts as they offer a more sustainable alternative to traditional proteins found in meat and soy.
The hope is that by shifting towards animal proteins, it could help to reduce the 64 million tons of carbon dioxide that is emitted each year from producing and the consumption of meat-based products.
Some companies say their insect farms only generate four per cent of the current emissions released each year by farms that maintain cows, pigs and chickens. Yay!
Using insect protein as a base requires far less feed, land and water, all of which generates fewer greenhouse gases per kilogram than those made with beef, pork or chicken.
'Global food systems face the challenge of providing healthy and adequate nutrition through sustainable means, which is exacerbated by climate change and increasing protein demand by the world's growing population,' the researchers, led by lead author Rachel Mazac, wrote in their paper.
'We estimate the possible reductions in global warming potential, water use and land use by replacing animal-source foods with novel or plant-based foods in people’s diets.'
