Following a two-day, DC-based workshop entitled “Saturated Fats: A Food or Nutrient Approach?” a group of leading nutrition scientists, mainly from the U.S., released a consensus statement detailing their findings on the latest research regarding the intake of saturated-fats and heart disease.

The addition of 3-Nitrooxypropanol to the feed of dairy cows reduced their enteric methane emissions by about 25% in a recently published study—one in a series of Penn State studies of the investigational substance in the United States—which might be an early step toward it being approved for use in this country.
A new research paper by Michigan State University scientists analyses the impacts of soil carbon sequestration on life cycle greenhouse gas emissions in Midwestern USA beef finishing systems and finds that eEmissions from the multi-paddock grazing system were offset completely by soil carbon sequestration and that soil carbon sequestration from well-managed grazing may help to mitigate climate change.
From the United States comes this good news about a new rule that has gone into effect curtailing use of antibiotics in livestock production with the aim of reducing the rise of antimicrobial resistance to drugs of medical importance.
Phil Thornton leads CGIAR research on institutions and policies for climate-resilient food systems.
