Which processed foods are better than natural?
In 2017, a group of researchers each bought fresh vegetables from different grocery stores and analysed their levels of nutrients, including vitamin C and folate, on the day they purchased them and five days later, after storing them in the fridge.
When they compared the frozen and chilled vegetables, they found that they had comparable levels of nutrients. In some cases, the paper found, the frozen vegetnables had higher levels than their fridge-stored rivals.
"There's a misconception that frozen produce isn't as good as its fresh counterparts, but that's truly inaccurate," says Ronald Pegg, food science and technology professor at the University of Georgia.
