8 Key Concepts
Stem Cells
Stem cells are early, primitive cells that can develop into any type of cell, forming our bodies from conception. After birth, about 70 million 'extra' stem cells are stored in places like bone marrow and are activated by distress signals (e.g., injury) to repair and regenerate organs from the inside out, becoming liver, nerve, blood vessel, or even brain cells as needed.
Ursolic Acid
Ursolic acid is a natural bioactive chemical found in the peels of fruits such as apples, pears, cranberries, and blueberries. Research has shown that this compound can stimulate stem cells to emerge from the bone marrow, contributing to regeneration and the repair of blood vessels.
Beta-D-glucan
Beta-D-glucan is a soluble fiber found in foods like mushrooms (especially in the stem), oats (e.g., steel-cut oats), and barley. This compound has been discovered to stimulate stem cells, particularly those involved in regenerating circulation and helping to repair and grow new blood vessels.
Proanthocyanidine
Proanthocyanidine is a natural plant-based bioactive present in high-cacao dark chocolate (80% or higher). Clinical studies have demonstrated that consuming enough of this compound can lead to its presence in the bloodstream, doubling the number of circulating stem cells and improving the resiliency of blood vessels.
Hydroxytyrazole & Oleocanthal
These are polyphenols found in olive oil, acting as natural substances with powerful effects on the body. They protect stem cells in the bloodstream by acting as 'police escorts,' helping them reach their destination safely and shielding them from damage.
Oxidative Stress
Oxidative stress is a condition in the body caused by various chemical exposures, such as fumes, vaping, off-gassing from carpets, artificial flavorings, preservatives, and cleaning materials. This stress can damage stem cells, and natural molecules like hydroxytyrazole from olive oil have been shown to protect stem cells against it.
EGCG (Epigallocatechin-3-gallate)
EGCG is a specific catechin, a type of polyphenol, found in tea. It is considered heart-healthy and beneficial for vascular health, working to protect blood vessels against oxidative stress, lower inflammation, and support gut health.
Chlorogenic Acid
Chlorogenic Acid is a polyphenol found in coffee. Like EGCG in tea, it contributes to heart and vascular health by protecting blood vessels from oxidative stress, reducing inflammation, and benefiting gut health.
7 Questions Answered
Stem cells are primitive cells that can develop into any cell type. After birth, about 70 million 'extra' stem cells are stored in bone marrow and are released in response to injury or distress signals to repair and regenerate damaged tissues and organs throughout the body.
Natural substances found in plant-based foods can activate the body's reserve stem cells, gently coaxing them into action to help repair and regenerate tissues in a more robust way, without necessarily needing a distress call.
Foods like fruit peels (containing ursolic acid), mushrooms, oats, and barley (containing beta-D-glucan), and dark chocolate (80%+ cacao, containing proanthocyanidines) have been shown to stimulate stem cells.
Consuming high-quality dark chocolate (80% cacao or higher) can introduce proanthocyanidines into the bloodstream, which has been clinically shown to double the number of circulating stem cells and improve the resiliency of blood vessels twofold within a month.
Olive oil contains polyphenols like hydroxytyrazole and oleocanthal, which act as protective escorts for stem cells in the bloodstream, shielding them from damage caused by oxidative stress from various environmental and dietary exposures.
To get the highest levels of polyphenols, look for extra virgin, first-press, monovarietal olive oils made from specific olive varieties like PICUAL (Spanish), Koroneiki (Greek), or Moriolo (Italian, Umbria).
Yes, both tea (containing catechins like EGCG) and coffee (containing polyphenols like Chlorogenic Acid) are heart and vascular healthy. They protect blood vessels against oxidative stress, lower inflammation, and contribute to gut health.
12 Actionable Insights
1. Prioritize Blood Vessel Health
Pay super attention to how well your blood vessels are functioning, especially after age 40, as healthy circulation is a critical starting point for optimizing all other aspects of your health.
2. Harness Food for Stem Cells
Understand that certain foods can stimulate and protect your vital stem cells, enhancing your body’s natural ability to regenerate and heal from the inside out.
3. Eat More Plant-Based Foods
Incorporate a variety of plant-based foods, including fruits, vegetables, nuts, legumes, healthy oils, and seeds, as they contain natural substances that can activate your stem cells.
4. Read Prepackaged Food Labels
Always check the ingredient labels of prepackaged foods, avoiding those with added sugar, emulsifiers, artificial chemicals, preservatives, and stabilizers; opt for minimal ingredients or prepare food yourself.
5. Focus on Net Daily Consumption
Recognize that the cumulative effect of your daily dietary choices, rather than isolated instances, significantly contributes to maintaining healthy blood vessels and overall circulation.
6. Small Tweaks, Big Impact
Make small, consistent dietary and lifestyle tweaks, as these choices can lead to profoundly important improvements in your future health, vision, brain function, and muscle strength.
7. Don’t Peel Your Fruit
Consume the peel of fruits like apples, pears, cranberries, and blueberries, as it contains ursolic acid which stimulates stem cells to aid in regeneration and blood vessel repair.
8. Eat Beta-Glucan Rich Foods
Include foods rich in beta-D-glucan, such as mushrooms (especially the stem), steel-cut oats, and barley, in your diet to stimulate stem cells and regenerate circulation.
9. Daily High-Cacao Dark Chocolate
Consume high-quality dark chocolate (80% cacao or higher), potentially as two cups of hot chocolate daily for 30 days, to double circulating stem cells and improve blood vessel resiliency.
10. Choose High-Polyphenol Olive Oil
Select high-quality extra virgin, first-press, monovarietal olive oils for their higher polyphenol content, which protects your stem cells against oxidative stress.
11. Select Specific Olive Varieties
When buying olive oil, look for monovarietal Spanish PICUAL, Greek Koroneki, or Italian Moriolo olives, as these varieties contain the highest levels of protective polyphenols.
12. Drink Tea and Coffee
Incorporate tea (containing catechins like EGCG) and coffee (containing chlorogenic acid) into your diet, as their polyphenols protect blood vessels, lower inflammation, and support gut health.
5 Key Quotes
A stem cell is basically a early primitive cell that has formed us. So when your dad's sperm met your mom's egg, and we were just this ball of cells, those cells all started as stem cells, which means that they could become anything.
Dr. William Li
If your blood vessels are healthy, you are at a really great starting point to optimize the rest of your health. But if your blood vessels are unhealthy, you're going to be far behind.
Dr. William Li
One of the most light bulb going off moments that I had as a food as medicine researcher to discover that natural substances in our food can similarly activate our stem cells and call them into action.
Dr. William Li
The stuff that you get in a packet at the grocery store, and it might taste really great... If you now take a look at the ingredient label... if you start seeing the added sugar and then the emulsifiers and all the artificial chemicals and preservatives and the stabilizers, that's probably not something that you want to actually put in your body.

Hydroxytyrazole, again, is one of those natural molecules that have been shown to protect your stem cells against oxidative stress.
