Ingredient Analysis of Dr. Lisa Newman

This is a wonderful analysis of ingredients found in most pet foods. The list was produced as a collaborative effort between pet food formulator Dr. Lisa Newman, N.D., Ph.D. (www.Azmira.com), Mike Adams (www.HealthRanger.org) and the non-profit Consumer Wellness Center (www.ConsumerWellness.org). Mike Adams and the Consumer Wellness Center compiled the following list of 448 ingredients found in pet foods available to the US market, and Dr. Newman has provided nutritional analysis and a description for each ingredient.

Dr. Lisa Newman has over 20 years experience in pet nutrition and nutritional therapies, and neither her nor Mike Adams were funded for this research.
