This led researchers to conclude that one thing about processed meals causes elevated calorie consumption and weight acquire.

Nonetheless, it needs to be famous that whereas energy between the diets had been the identical, vitamin wasn’t. The ultra-processed eating regimen group acquired much less fiber and protein and extra added sugars–vitamins related to urge for food management.
