Statement in Response to 'Analysis and Valuation of the Health and Climate Change Cobenefits of Dietary Change'Tuesday, March 22, 2016
Attribute Statement to Barry Carpenter, President and CEO, North American Meat Institute
“The notion that global veganism is a nutrition and environmental panacea is flawed at its core and dozens of recent studies bear this out.
The authors of the recent paper published in the Proceedings of the National Academy of Sciences suggest that somehow consensus exists that a diet lower in meat is healthier but we think no such consensus exists. In fact, recent research points to the many health benefits of a balanced diet that includes meat in ensuring brain development in children, maintaining brain function later in life, preventing sarcopenia and anemia, and providing a sense of “satiety” or satisfaction, which helps prevent obesity.
Many papers, such as a recent summary by Dr. David Klurfeld, emphasize the benefits of meat in the diet and the risks associated with a diet that excludes meat. In fact, more than a dozen recent studies detail issues associated with the nutritional inadequacies associated with some vegan diets. Those problems include B12 deficiencies and associated development issues, eating disorders, mood and mental disorders, subclinical protein malnutrition, hyperhomocysteinemia and the increased vulnerability of some vegetarians to cardiovascular diseases.

In addition, one of the world’s experts on the environmental impact of livestock production, Dr. Frank Mithloehner of the University of California Davis reviewed the paper and concluded, “Comparing the 4.2% GHG contribution from livestock to the 27% from the transportation sector, or the 31% from the energy sector in the United States, puts all contributors into perspective.”
When all the data on nutrition and environmental impact are reviewed together, a compelling case continues to exist for making meat a part of a healthy balanced diet while continuing to look for ways to raise livestock and produce meat in the most sustainable ways possible.”
