In Your Health Is at Risk, Dr. John addresses misinformation surrounding the treatment of Type 2 diabetes and other diseases categorized as lifestyle illnesses; disinformation in the Trump Administration’s initial response to the pandemic; and missing information on the impact of diet and carbohydrates in cancer and heart disease. His mission is to make us more informed, engaged, and literate health care consumers. Patients want answers to questions regarding their health. Each chapter of Your Health Is at Risk contains questions patients can ask so that both the patient and doctor are better informed about health care choices.


After 20 years of studying the research on diabetes, Dr. Poothullil explains in this book that insulin resistance does not make biological sense. Instead, he shows how a normal body metabolism can go haywire when you overconsume grains, leading to high blood sugar and diabetes. If you avoid eating grains as much as possible, you can lower your blood sugar and halt the progression of diabetes. In this way, diabetes is lifestyle and dietary condition, not a hormonal disease, that you can reverse in as few as 8 weeks. Take control of your diabetes and read this life-changing book.

Surviving Cancer

Receiving a diagnosis of cancer is terrifying—and you may feel like there is little you can do. But Dr. Poothullil explains how many cancers are survivable. Surviving Cancer will give you renewed hope and a clear program of dietary and cognitive/emotional changes that can help you defeat your cancer and return to health. This book is for anyone who is currently diagnosed with cancer and cancer survivors who want to ensure they do not develop it again.

When Your Child Has Cancer

If you are the parent of a child with cancer, the questions and feelings you have can be overwhelming. In this insightful and thoughtful book, you will find information, hope, advice, and solace. Dr. John Poothullil expertly guides you to understand childhood cancer. He offers two new scientific theories to explain how the leading types of childhood cancers might occur, given that children have not lived long enough to develop the number of gene mutations that usually cause adult cancers. You will learn how you as parents can care for your child with cancer. Most importantly, you will learn how your child’s diet can be a key corollary element in controlling cancer along with the medical treatments. 

Eat, Chew, Live

In Eat Chew Live you will learn how to change your approach to food and eating – to ensure that you can prevent diabetes from happening to you. Dr. Poothullil explains how the mysterious development of “insulin resistance” is an incorrect theory on the cause of diabetes and explains in clear terms how grains cause you to produce an oversupply of glucose that your body cannot use, leading to weight gain and eventually high blood sugar. Preventing diabetes is entirely possible – read how and why.
