In this enlightening discussion, Dr. Michael Greger, a physician and author known for his expertise in nutrition and aging, unveils how 'zombie' cells accumulate in our bodies, fueling chronic inflammation as we age. He reveals the power of everyday foods: fisetin from strawberries, quercetin from red onions, and piperlongumine from long pepper. Just a teaspoon of onions or a handful of strawberries can trigger significant health benefits. Discover why these foods are nature's answer to combating inflammation and promoting healthier aging.

Senescent Cells Drive Inflammaging
Cells only divide a limited number of times (Hayflick limit) and then signal the immune system to remove them.
As immunity declines with age, senescent cells accumulate and drive chronic inflammation.

Eat Antioxidant Foods To Protect Cells
Prevent premature senescence by eating antioxidant-rich foods like berries and greens.
Flood your body with antioxidants to reduce DNA damage from free radicals.

Senolytics Clear Zombie Cells But Can Be Toxic
Senolytic compounds clear 'zombie' senescent cells and may reverse inflammation.
Many pharmaceutical senolytics have severe side effects, limiting broad use.

"Our body's tissues get littered with these senescent cells spewing out inflammation" - Dr. Michael Greger
Dr. Michael Greger walks through one of the most fascinating discoveries in aging research: your cells are supposed to divide about 50 times, then release inflammatory signals so your immune system can clear them out. It's a brilliant protective mechanism against cancer. But here's what's quietly sabotaging your health: as you age, your immune system starts losing its ability to remove these cells. They pile up in your tissues, pumping out inflammation day after day, which is why your blood markers for inflammation climb with every passing year. Scientists call it "inflammaging." These zombie cells are literally sitting in your body right now, actively contributing to the chronic inflammation driving disease and aging.
The game-changer? Scientists tested dozens of drugs to clear these cells, but they had brutal side effects. Then they found three compounds in everyday foods that actually work: fisetin in strawberries, quercetin in red onions, and piperlongumine in long pepper. Dr. Greger shares the research showing people experiencing measurable benefits from eating as little as a teaspoon of chopped onions or a handful of fresh strawberries daily. He explains exactly why red onions beat white onions, why he personally switched from blackberries to strawberries despite their lower antioxidant content, and where to find long pepper to add to your diet. This isn't about taking another supplement or following a restrictive protocol. It's about understanding what's actually aging your body at the cellular level and using specific, accessible foods to fight back.
