Diets high in red meat, especially processed meat, have been associated with a wide range of health consequences including obesity, type 2 diabetes, cardiovascular disease, and some cancers. Based on a comprehensive review of epidemiologic evidence, the International Agency for Research on Cancer of the World Health Organization classified processed meats such as hot dogs, bacon, and sausages as carcinogenic to humans for colorectal cancer, and unprocessed red meats, such as beef and pork, as “probably carcinogenic.”1 In addition, there is growing concern that industrial meat production can contaminate natural resources, including rivers, streams, and drinking water, with nutrients from animal waste lagoons and runoff. There is also concern that the raising of livestock can lead to the loss of forests and other lands that provide valuable carbon sinks as well as the large amounts of greenhouse gas emissions that contribute to the ongoing environmental and climate-related issues.2
