Taxing fatty foods and fizzy drinks and subsidising fruit and vegetables could improve the diet and health of the nation.
That's the view of researchers who've reviewed more than 30 international studies on how food prices affect purchasing decisions.
Auckland University researcher Helen Eyles says food pricing is the key factor in the decision-making process.
She says similar taxes in Denmark and France have seen changes in people’s food-buying habits – but that subsidies can also cause further problems with people using their savings to buy unhealthy foods – and the science sector must continue to look into the issue.
“Our role as scientists is to provide the best evidence possible,” she told Firstline this morning.
