PHYSICIANS ASSOCIATION FOR NUTRITION

The Physicians Association for Nutrition (PAN) International aims to raise awareness among health professionals, the general public, and policymakers about the role of whole food, plant-based nutrition in promoting good health and preventing and treating disease.

PAN International was founded in 2018 as an officially recognized nonprofit organization located in Munich, Germany.

PAN is expanding and constantly launching new national PAN offices around the world to work effectively under local conditions and maximize impact.

PAN works to:

 

Educate Medical Students & Health Professionals

⇒ We deliver evidence-based nutrition and health information, reevaluating our content regularly in accordance with the newest available and most thoroughly researched findings, while recognizing—and addressing—the opportunities and limitations of particular research results and established scientific methods. We appreciate, welcome, and foster scientific exchange and discussion.

Support Patients in Dietary Changes
  • by providing easy-to-follow educational resources and tools to optimally support patients in the prevention and treatment of diseases
  • by providing effective nutrition programs and workshops

⇒ We serve people so that they can discover and use their own abilities to choose a healthier life. We aim to inspire and provide guidance while appreciating every single step an individual makes.

Build a Global Network
  • by connecting health professionals, scientists, and medical students
  • by establishing PAN student groups at universities
  • by founding national PAN offices around the globe in order to effectively work under local conditions and maximize impact

 As part of a global network, we stand up for the common goal of improved health. We seek to expand and strengthen our network by inviting new partners to support, critique, and evaluate our actions. In doing so, we create a paradigm shift, driving a worldwide community and making sustainable change possible.

Create an Influential Medical Lobby Organization

⇒ to promote political change and bring nutrition to the heart of health-care systems and communities

As a general practitioner in the field of clinical nutrition, author and professional speaker, I have been addressing public health issues for over two decades. What I learned and found most disturbing is the lack of education of health professionals regarding nutrition, its effects on the human body, and its preventive and therapeutic potential.
By providing evidence-based educational material and events, PAN will have a great impact on the education of the general public and health professionals alike.
I am honored to be a member of PAN International.

The medical profession continues to enjoy the trust of its patients, but the health potential of a whole food plant-based diet has not yet spread among all health professionals. Therefore, I welcome the creation of PAN and support its work to promote the importance of nutrition for the prevention and treatment of chronic diseases.

Prof. Dr. Leitzmann

PAN is committed to supporting and encouraging changes in our views on the role nutrition and WFPB diets play in “lifestyle diseases.” I believe investing in the education of health professionals and the general population may be the key determinant that brings about a decrease in the prevalence of these chronic diseases.

Sophia Shalhout

Among the patient population that I see on daily basis, the major comorbid diseases are diabetes mellitus and obesity. I cannot stress enough and will continue to do my best to promote lifestyle education predicated on evidence-based medicine, showing my patients that it is possible for anyone to work towards a WFPB diet. I believe that patients can be cured or can stop the progression of such diseases if they can be conscious of what they eat. I am so fortunate to be a part of an organization like PAN, which strives to give nutrition a higher status in medicine as a whole.

The current scientific evidence points to a diet centered around whole, unrefined, or minimally processed plant foods including fruits, vegetables, whole grains, legumes, spices, nuts, and seeds.

This is what can be described as a “whole food, plant-based diet.” We will closely monitor the latest evidence in order to continuously reevaluate and update our content and recommendations.
