Dr. Campbell’s excellent book is critical of statistics related to health issues in populations eating meat. Understandably, there are problems with eating meat because by and large the meat people are eating these days represents a dangerous food. I agree with absolutely avoiding the type of meat that people consumed in his studies. These are meats from grain-fed animals, which are most commonly genetically modified. In addition, these are cattle who have been treated with antibiotics and who knows what else.
