arises from my annual review of the medical literature. With the help of a team of hundreds of volunteers, we churned through tens of thousands of scientific papers published in the peer-reviewed nutrition literature and are ramping up to break new records in 2022. How do I choose which studies to highlight? In general, I strive to focus on the most groundbreaking, interesting, and useful findings, but which topics resonate the most? The practical ones, offering cooking or shopping tips, or those that dissect the studies behind the headlines? Maybe the geeky science ones that explore the wonderfully weird world of human biology are the most popular. As you can see from the below list, the answer is a bit of all of the above.


I’m sorry this originally came out after pomegranate season ended, but you should be able to find them now! This is one of my favorite ways to eat BROL (barley, rye, oats, and lentils) for breakfast.

My Basic BROL—found in The How Not to Diet Cookbook—can be used in all kinds of savory or sweet ways, packing in a lot of prebiotic nutrition and helping to tick off those grain boxes on your Daily Dozen Checklist. For extra credit, sprinkle some matcha on top.


What are the risks versus benefits of drinking kombucha? I’m glad I was finally able to post an update. *Spoiler Alert* There are better options. Check out What Are the Best Beverages?


This was the first in a controversial seven-part video series documenting how stents perform compared to placebo (fake) surgery. Here are the next six in the series:


Tragically, the leading risk factor for death in the United States is the American diet—but that means we have the power to change it! The media likes to inflate the controversies, but the science has been clear for decades about the core tenets of healthy eating and living.


That was a common question during my monthly Q&As so I did a deep dive and created a nine-video series on the topic, including:

For a healthful, whole-food veggie burger, check out my recipe for Black Bean Burgers from my first cookbook.


What is the dirty little secret of drugs for lifestyle diseases? If patients knew the truth of how little these drugs actually worked, almost no one would agree to take them. This was part of a four-part series on statins, which includes:

Another popular video of 2021 was How Low Should You Go for Ideal Cholesterol Levels?. I explore how having a so-called normal cholesterol in a society where it’s normal to drop dead of a heart attack isn’t necessarily a good thing.


Thyroid health is another topic I got asked about a lot. In this video, I explore whether the apparent protection of plant-based diets for thyroid health is due to the exclusion of animal foods, the benefits of plant foods, or both. The other three videos in this series are:

One common cause of an underactive thyroid is autoimmune thyroiditis. Another popular video from this past year explores one tool for dealing with this friendly fire: Fasting for Autoimmune Diseases. See our fasting topic page for even more.


Nonalcoholic fatty liver is now a leading cause of liver failure. In this video, I address the three sources of liver fat and how you can get rid of it.


I’m excited people found this video as fascinating as I did. If you aren’t blown away by the eye-opening revelations, you may want to watch it a second time to fully absorb it all.

One of the reasons I love my work so much is that I love learning. That’s the first thrill. The second is being able to share the knowledge. In this video, I discussed that palmitic acid, a saturated fat concentrated in meat and dairy, can boost the metastatic potential of cancer cells through the fat receptor CD36.

I had never even heard of CD36 until recently! I followed this video with How to Help Control Cancer Metastasis with Diet and The Food That Can Downregulate the Metastatic Cancer Gene. I can’t wait to find out what I’m going to learn next year!

Speaking of discoveries, check out another popular video from this year, Boosting Anticancer Immunity with Forest Bathing. Visiting a forest can induce a significant increase in both the number and activity of natural killer cells, one of the ways our body fights off cancer. But why? The big reveal is in the follow-up: Why Does Forest Bathing Boost Natural Killer Cell Function?.
