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 Inflammatory Bowel Disease with […]

When I dove into the scientific research for my book How Not to Age, I uncovered the best ways we can care for our skin as we mature. What are the most important lifestyle factors? The best topical creams? Are there any beneficial procedures? This infographic summarizes the main takeaways. Get this infographic as a

What are the three sources of liver fat in fatty liver disease, and how can we get rid of it? Nonalcoholic fatty liver disease (NAFLD) is now the most frequent chronic liver disease, thanks in part to our epidemic of obesity, and is even seen in children. “[N]early 70–80% of obese children may have NAFLD.”

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. If action is not taken now, the next pandemic could be far

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.” An analysis of the nutritional value

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”—sometimes, much later. The Women’s Health Initiative study showed that giving women Premarin, a

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, but patients didn’t seem to get the memo.

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 performed in the United States.” Though they appeared to offer immediate relief of angina chest pain in

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 artery disease, despite clear evidence that it provides minimal benefit…” The procedure does not prevent heart attacks

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 placement don’t actually prevent
