Highly processed foods make up 67% of youth diets, Friedman study finds

As smartphones, online shopping and cryptocurrency have become more prevalent in the past 20 years, so too have ultraprocessed foods, which make up the majority of youth diets. The percentage of child and adolescent diets composed of ultraprocessed foods — those made with refined ingredients and additives — hasincreased from 61% to 67% in the past 20 years, according to a recent Friedman School of Nutrition Science and Policy study published in the Journal of the American Medical Association. The findings may have implications for combating the development of ultraprocessed food-related disease in adulthood.

Op-Ed: The university’s climate responsibility

Correction: In the Dec. 11, 2016 op-ed “The university’s climate responsibility,” by Bruce Everett the sentence "Research suggests that climate sensitivity is in fact near or even below the bottom end of the IPCC range — on the order of two degrees celsius or fewer” was changed to  "Actual evidence strongly suggests that climate sensitivity is in fact below even the bottom end of the IPCC range – on the order of one degree Celcius or less for a doubling of atmospheric carbon dioxide.” This correction was made after the Daily received evidence substantiating the latter statement.
