This end result demonstrated that “each ultra-processed and fewer processed meals can have a low wholesome consuming rating,” Allen Levine, professor emeritus within the Division of Meals Science and Diet on the College of Minnesota in St. Paul, informed UPI through electronic mail.
Levine categorized the totally different meals within the NOVA system for the research.
“Moreover, ultra-processed meals with a wholesome consuming rating much like that of much less processed meals have an extended shelf life and are inexpensive,” Levine mentioned.

For the brand new research, the researchers requested the other query: Is it potential to create a low-quality menu that will get most of its energy from “easy” meals?
To reply that query, they constructed a much less processed menu, which obtained 20% of its energy from ultra-processed meals, and a extra processed menu, which obtained 67% of its energy from ultra-processed meals. The NOVA system decided the extent of processing concerned in every menu.
The researchers estimated that the menus had a Wholesome Consuming Index rating of about 43 to 44 out of 100, a comparatively low quantity that displays poor compliance with the Dietary Pointers for Individuals.
