Causes or Cures Is Sugar the Most Misused Word in Health? With Dr. John Lewis
Can a plant-derived polysaccharide formula affect Alzheimer’s symptoms? A researcher explains his study, and its limits.
In this episode of Causes or Cures, Dr. Eeks speaks with researcher Dr. John Lewis about his study investigating an aloe polymannose multinutrient supplement in Alzheimer’s disease.
We discuss what polymannose is, why he feels mainstream wellness gets sugar wrong, why the intervention combines multiple nutrients rather than a single compound, and the biological theories behind how it might influence inflammation and immune signaling.
Dr. Lewis also walks through the study design, including the open-label approach, the cognitive and functional outcomes measured, his thoughts on testing against a placebo, and how to interpret mixed results across different tests.
We also talk about the bigger question: what early nutrition studies can suggest — and what they cannot yet prove.
John E. Lewis, Ph.D., is Founder and President of Dr Lewis Nutrition® and a Voluntary Associate Professor at the University of Miami Miller School of Medicine. His research focuses on nutrition, dietary supplementation, and exercise in human health and disease, and he has led or contributed to over 30 studies and more than 180 peer reviewed publications.
Dr. Lewis has presented his work nationally and internationally, mentored students across all levels of training, and delivered a TEDx talk on nutrition and brain health. He is also a Diplomate and Faculty Member of the Medical Wellness Association and continues to promote evidence based approaches to health and wellness.
