Jill Brook, MA is a long-time nutritionist, researcher, and autoimmune dysautonomia patient. She earned degrees from Princeton University and UCLA, worked as a researcher and nutritionist at UCLA and the Pritikin Longevity Center, then became a nutritionist in private practice in Pasadena, California. She counseled individuals and families, consulted for Caltech and Disney, wrote books, trained other nutritionists around the globe, but gradually became too sick with dysautonomia to run her busy practice. She was homebound for years, but eventually worked her way back to feeling great again. She has since focussed on nutrition for chronic illness patients, especially those with autoimmunity and complex nutritional challenges.
