Campbell's primary argument against the Paleo diet is that excessive consumption of animal protein causes diseases such as cancer, diabetes, multiple sclerosis, osteoporosis, kidney stones and heart disease. Campbell cites increased cancer rates in countries that consume more animal products in support of this assertion. Campbell's claim that diets based on high consumption of animal proteins and increased disease rates is supported by several factors including that the animals themselves are often unhealthy, that cooking animal meat at excessively high temperatures has negative effects, and that most meats are processed with chemicals and preservatives.
Campbell is a vegan and advocates a diet with lower total protein consumption as well as the elimination of animal-based foods. Campbell believes that the elimination of animal proteins from the diet can help prevent, or even reverse, certain diseases.Learn more about Diet Plans
