Paul Jaminet, an astrophysicist, and Shou-Ching Jaminet, a molecular biologist and cancer researcher, were both chronically ill in their middle years and each lost a parent at a very young age. After unsuccessful attempts to regain their health, they dedicated their entire research spirit for several years to the topic of human nutrition and its potential for healing. They developed five premises to evaluate the research findings. They adjusted their diet according to the insights gained during their research journey and both became healthy. Their blog encouraged others to follow their example, leading to remarkable results as well. The "Perfect Health Diet" was born. A bestseller in America, it is now available in German translation and adapted to local dietary habits. The goals of this diet are achieving a healthy weight, the disappearance of diseases, and improved well-being.
