Is the Nova Rating Correct About Processed Vegan Protein?

“You’re being lied to about ‘ultra-processed’ meals,” reads a current Vox headline.

The majority of the plant-based ultra-processed energy as an alternative got here from what the authors describe as ‘industrialised packaged breads, pastries, buns, and desserts,’ and ‘biscuits,’ higher recognized within the US as cookies—meals which have little to do with plant-based meats or different specialty vegan merchandise. The brand new technology of vegan burgers, together with Unimaginable and Past burgers, didn’t but exist when the info was collected between 2009 and 2012.”
