Renew Your Body

The hidden reason you’re unhealthy and the science-backed plan to fix it.

In this groundbreaking book, a leading expert in functional medicine reveals the missing piece of the puzzle.

Exhaustion. Brain fog. Weight struggles. Chronic health issues. Chances are you’ve experienced at least a few of these, only to be told that the root issue was genetics, bad habits, or simply getting older. For decades, health experts have told us to avoid toxins, eat healthy, and exercise more. Yet chronic disease keeps rising. And millions more feel the effects without receiving a diagnosis.

The actual culprit? The breakdown of the body’s most critical defense systems.

Dr. David Friedman was the epitome of good health—until he was blindsided by a severe Crohn’s diagnosis which left him sick for two years and bedridden for five months. Facing a lifetime of infusions, medication, and surgery, his desperate search for answers led him to a discovery that changed everything: filter repair, which enabled him to return to optimal health.

Combining cutting-edge research, real-life patient transformation stories, and a step-by-step, science-backed plan to restore your body’s critical defense systems, Renew Your Body is a comprehensive guide that explains:

• The 8 essential filters in your body—and why common conditions, including fatigue, IBS, Alzheimer's, metabolic disorders, cardiovascular disease, and even cancer can all be traced back to faulty filters.
• The hidden ways "healthy" foods and supplements may be damaging your filters and triggering disease.
• How toxins in everyday items—your shower curtain, your water filter, even your grocery receipts—are quietly sabotaging your health and taking years off your life.
• A proven method to restore your body’s natural filtration system, stop disease before it starts, and reprogram your cells for renewal.

Fix the filter, fix the disease. Take control of your health and renew your body at any age.
