Dear Secretary Vilsack and Secretary Burwell,
As a citizen and a taxpayer concerned about the sustainability of our health and our planet, I applaud the Dietary Guidelines Advisory Committee (DGAC) for including the major findings represented in Chapter D.5: Food Sustainability and Safety regarding plant-based diets as more health promoting and associated with less environmental impact than the current U.S. diet.
In late 2014, the international affairs think-tank Chatham House released a study which concluded that it is unlikely global temperature rises can be kept below two degrees Celsius without a radical shift in global meat and dairy consumption. However, they found that there is a striking lack of efforts to reduce consumption of meat and dairy products due to not least, government’s fear of backlash to pursue policies that would shift consumer behavior. The absence of attention afforded to the issue among policy-makers contributes to a lack of research on how best to reduce meat and dairy consumption, which the health of our nation and our planet can no longer afford.
