What are the risks versus benefits of drinking kombucha?Is Kombucha Tea Good for You? is one of my first videos. It was featured in a blog entry entitled “NutritionFacts.org: the first month,” where I marveled the video had reached nearly 100,000 people. You can see it below and at 0:20 in my video
What were the results of a randomized, double-blind, placebo-controlled trial of a daily half teaspoon of powdered black cumin in Hashimoto’s patients?“Autoimmune thyroiditis, also known as Hashimoto’s thyroiditis, is an organ-specific autoimmune disorder,” where our body attacks our own thyroid glan
Is the apparent protection of plant-based diets for thyroid health due to the exclusion of animal foods, the benefits of plant foods, or both?Several autoimmune diseases affect the thyroid gland, and Graves’ disease and Hashimoto’s thyroiditis are the most common. Graves’ disease results in hyperthy
How much nori, dulse, or arame approximates the recommended daily allowance for iodine?Dairy milk supplies between a quarter and a half of the daily iodine requirement in the United States, though milk itself has “little native iodine.” The iodine content in cow’s milk is mainly determined by factor
Most plant-based milks are not fortified with iodine.“Adequate dietary iodine is required for normal thyroid function.” In fact, the two thyroid hormones are named after how many iodine atoms they contain: T3 and T4. “Given that iodine is extensively stored in the thyroid gland itself, it can safely
How effective are flu shots, elderberries, echinacea, and cranberries?The U.S. Centers for Disease Control and Prevention (CDC) recommends that everyone over the age of six months get a routine flu shot every year, unless you have some sort of contraindication, such as an allergy to any of the vacci
Worldwide, physical inactivity accounts for more than 10 million years of healthy life lost, but what we eat accounts for nearly 20 times that. As I discuss in my video Fewer Than 1 in 5,000 Meet Sodium and Potassium Recommended Intakes, unhealthy diets shave hundreds of millions of disability-free
More than 95 percent of human exposure to industrial pollutants like dioxins and PCBs comes from fish, other meat, and dairy.By cultivating muscle meat directly, without associated organs like intestines, the incidence of foodborne diseases “could be significantly reduced,” as could exposure to anti
Medically important antibiotics are being squandered by animal agriculture to compensate for typical factory farming practices.Cultivating muscle meat directly from cells instead of raising and slaughtering animals would reduce the risk of foodborne illnesses “due to fecal contamination during slaug

What are the direct health implications of making clean meat—that is, meat without animals?In a 1932 article in Popular Mechanics entitled “Fifty Years Hence,” Winston Churchill predicted that we would one day “escape the absurdity of growing a whole chicken in order to eat the breast or wing, by gr
Why is the incidence of side effects from statins so low in clinical trials while appearing to be so high in the real world?“There is now overwhelming evidence to support reducing LDL-C (low-density lipoprotein cholesterol)”—so-called bad cholesterol—to reduce atherosclerotic cardiovascular disease
Switching to a plant-based diet has been shown to achieve far better outcomes than those reported on conventional treatments for both active and quiescent stages of Crohn’s disease (CD) and ulcerative colitis.Important to our understanding and the prevention of the global increase of inflammatory bow
Plant-based diets can be 98 percent effective in keeping ulcerative colitis patients in remission, far exceeding the efficacy of other treatments.“One of the most common questions physicians treating patients with IBD [inflammatory bowel disease] are asked is whether changing diet could positively a
Eating a diet filled with animal products can disrupt our microbiome faster than taking an antibiotic.If you search online for “Crohn’s disease and diet” or “ulcerative colitis and diet,” the top results are a hodgepodge of conflicting advice, as you can see below and at 0:15 in my video Preventing

In the United States in January 2025 alone, approximately 20 million commercially-raised birds, mostly egg-laying hens, were affected by the highly pathogenic avian influenza (H5N1). These numbers are staggering yet barely scratch the surface of a potentially larger threat looming over the country.
What do hospitals have to say for themselves about serving meals that appear to be designed to inspire repeat business?“Hospital food needs a revolution.” I was surprised to learn that most inpatient meals served in hospitals are “not required to meet national nutrition standards for a healthy diet.
Cardiologists can criminally game the system by telling patients they have much more serious, unstable diseases than they really have—fraud that results in unnecessary procedures, unnecessary costs, and unnecessary patient harm.“The history of medicine abounds with dogmas assumed and later overcome”
Again and again, studies have shown that doctors tend to make clinical decisions for patients based on how much they themselves will get paid.In 2007, we learned from the COURAGE trial that angioplasty and stents—percutaneous coronary intervention (PCI)—don’t reduce the risk of death or heart attack
Sham surgery trials prove that procedures like non-emergency stents offer no benefit for angina pain—only risk to millions of patients. Angioplasty and stents—percutaneous coronary intervention (PCI)—for stable, non-emergency coronary artery disease are among “the most common invasive procedures per
What do physicians and stent companies have to say for themselves, given that they promote expensive, risky procedures with no benefit?“Percutaneous coronary intervention (PCI)”—angioplasty and stent placement—“continues to be frequently performed for patients with stable [non-emergency] coronary ar
Why are doctors killing or stroking out thousands of people a year for nothing? How do doctors even convince patients to sign up for procedures that are all risk without benefit?Millions of people have gotten stents for stable coronary artery disease (CAD), yet we now know that angioplasty and stent
