Over the past 30 years, Donna has become one of the most respected authorities in the field of digestive health, diet, and nutrition. She was the first to introduce the popular sweetener stevia to the public here in the US, and her first book, The Body Ecology Diet, introduced the world to a sugar-free, gluten-free, casein-free, and probiotic-rich diet and a way of life that is now followed by tens of thousands of people around the world. Now she is focusing her attention on Nutritional Genomics, a brilliant new field of science that studies the effect of gene-diet interactions, opening the door to the most comprehensive, detailed, and genetically personalized nutrition plans ever designed --and unlocking your personalized pathway to health.
