Omega-6 Linoleic Acid Is Not What Makes Seed Oils Bad

Introduction: Clearing Up Confusion About Omega-6 Linoleic Acid in Seed Oils You might have heard that seed oils, like soybean or corn oil, are bad because of a fat called omega-6. People say omega-6 causes health problems like diabetes or heart trouble because it’s “inflammatory.”  That’s a myth we need to bust! Omega-6 isn’t the real villain. The problem is how certain seed oils are made. Let’s learn about the eight unhealthy oils—I call them the “hateful eight”—and why they hurt your body. This simple story will show you the truth. What Are the Hateful Eight? The “hateful eight” oils…

Toxic Seed Oils Turn French Fries Toxic, Sadly

French fries are a beloved indulgence, but the toxic seed oils used to fry them can transform this treat into a health hazard. You may have seen this photo of cigarettes in a French fry cup before. It’s an AI-generated image. But it’s not just a made-up meme. It started circulating shortly after I was interviewed for this movie. During the interview, I made the rather shocking comparison between cigarettes and French fries. That comes from a study called: Toxic Lipid Oxidation Product (LOP) Generation in Culinary Frying Oils (CFOs) During High-Temperature Frying Practices: Passage into Fried Foods. In it,…

Why are seed oils unhealthy?

Why Seed Oils Are the Biggest Threat to Your Health Seed oils,  also known as vegetable oils, or more precisely as The Hateful Eight, are not benign. To best understand why seed oils are harmful, we need to understand a biological process called oxidative stress. Oxidative stress: the great disease promoter. Understanding oxidative stress is crucial if you’re interested in health or nutrition science. I have spent over two decades researching various diets and their ability to prevent or promote oxidative stress. Oxidative stress is the root cellular process driving all known diseases. It occurs when free radicals—unstable molecules—overwhelm the…

Did Leading Nutrition Experts Manipulate Data in Widely Cited Seed Oil Study

JAMA Internal Medicine published the first-ever study comparing butter to seed oils. But they skewed the data to the point of absurdity. Time and again, I’ve seen supposedly peer-reviewed studies making conclusions that defy common sense. Especially seed oil studies. This latest journal is one of the worst examples I’ve come across. I’m going to break down what they did and how they got away with it in this article. Their paper is especially important. It’s the first, to my knowledge, to compare seed oils head to head with butter. More than 70 years have passed since health authorities started…

Why do we get hangry?

Hangry is not normal hunger. Normal hunger is usually brought about by smelling food. It’s also common to feel normal hunger around our normal mealtimes because our digestive system has its own internal clock that keeps excellent track of time. (This is why your dog or cat always seems to know when it’s dinner o’clock.) Ordinary hunger does not make us angry or irritable. And unless we’ve gone for days without eating, normal hunger is a light stomach-grumbling sensation that goes away when we ignore it. Hypoglycemia makes us hangry. Hangry on on the other hand is hard to ignore.…

Why My Magnesium Supplement of Choice is Magnesium Oxide

TLDR: I use and recommend Magnesium Oxide because it is more compact and easier to swallow. Also, being physically smaller, we only need to swallow a single pill. Studies claiming it doesn’t get absorbed are suspect. My approach to supplementation is minimal. I do recommend magnesium as well as a few other minerals and vitamins. (To learn which ones and why click HERE.) One of the most common questions I get is Why do you recommend magnesium oxide and not one of the other more bioavailable magnesium formulations? This question reflects the common belief that some magnesium formulations don’t get…

Attention Keto Dieters: Seed Oil is Worse than Sugar

Fellow members of the keto community, keto dieters everywhere, we need to talk. I want to convince you that any amount of seed oils is way worse than small amounts of sugar. Ketones are not the miracle cure for all that ails us. A healthy metabolism is. The only reason we can’t see this is because we’ve been lied to about fats.  Seed oils destroy our metabolism. Sugar doesn’t. AFTER seed oils make us sick and insulin resistant THEN sugar can potentially become toxic to us. But because of HOW seed oils harm our body fat and mitochondria, cutting carbs…

Low Smoke Point Olive Oil on High Heat–Is It Safe?

Olive Oil has a Low Smoke Point. Can you still cook with it? We’ve all heard a thousand times high smoke point oils like soy and canola are the oils of choice for cooking–especially high-heat cooking. This is a particular concern for professional chefs who typically cook with temperatures far higher than those used by a home cook. If the oils aren’t smoking that must mean, the thinking goes, that they are chemically stable. No smoke, no free radicals, no toxins. No problems. But I want you to set aside, for a moment, everything you’ve been told about smoke point…

Guilt by Association: Salt Is Not Even A Little Bad For Our Health

You might think salt makes you bloated. It’s actually something else. We hear all the time that salt is bad for us. So my patients who notice swelling or bloating after eating salty junk food naturally assume salt caused their symptoms. But of all the ingredients in junk food, salt is the least likely to cause health problems.  I grew up surrounded by messaging that salt was bad but I was always skeptical. Probably because my dad, a doctor, always snatched up the shaker and doused his food in salt before even tasting it. He’s done that his whole life,…

Blue Zones Website Misrepresents Diets

The Blue Zones book has powerfully influenced medical thinking on nutrition. But the Blue Zones website and Adventist Healthcare system contradict the reality of people’s diets that are presented in the book itself.

Who Teaches Doctors About Cholesterol-lowering Drugs?

Did you know that the cut off for “high” cholesterol used to be nearly twice as high as it is today? The number considered low enough has had to shift downward multiple times. Cholesterol-lowering “targets” are lower today than ever before. And lately, heart attacks are increasing.
