"Thank you for teaching me that the human being is what he eats. It is revealed in our body, our mind and our actions." - Jacqueline Gabriel

An optimal microbiome is the key to a life of health and well-being.

About the author

I graduated from El Bosque University (Bogotá, Colombia) as a medical doctor. I had a belief that as a doctor I knew what it takes to be healthy. I took care of my body, exercised a lot and ate what I considered healthy.

However, a few years later I was diagnosed with a stage three cancer in the left vocal cord. I was wondering how this can happen to me as I am a medical doctor, I didn't smoke and I had a "healthy" lifestyle.

My cancer led me to study more about alternative and natural methods of preventing and treating illnesses. The detailed story of my recovery and the studies that followed can be found in the book. 

Many years have passed since I had cancer and my health is perfect. Thanks to my professional development and life experience, I have learned that the best way to cure any disease is to prevent it.

Currently, I am dedicated to helping people who want to reach an optimal level of health through natural methods and thus prevent the disease. Similarly, if a person has cancer or any other illness and would like to obtain treatment with means other than allopathic or conventional medicine, it is my pleasure to help them.

I travel the world giving lectures, doing seminars and workshops to share my testimony, knowledge, and experience.

Thank you for your interest in my new book! Make the changes suggested in the book, and I am sure you will reach new levels of health.
