"When you spike your blood sugar level several times a day, every day, it is exactly like taking sandpaper to the inside of your delicate blood vessels," he writes, with the cool hand of a surgeon who has "peered inside thousands upon thousands of arteries." His eye for imagery is also hardened. "Take a moment to visualize rubbing a stiff brush repeatedly over soft skin until it becomes quite red and nearly bleeding," he writes. "This is a good way to visualize the inflammatory process that could be going on in your body right now."

Lundell blames not only the refined carbohydrates, but the proportion of omega-6 to omega-3 fatty acids in Western diets. Excessive omega-6 acids create inflammation, and American diets that are high in corn and soybean oils often involve omega-6:omega-3 ratios around 15:1. Lundell is not alone in saying that the ratio should ideally be around 3:1. He gets into the popular hunter-gatherer reasoning there, that "the human body cannot process, nor was it designed to consume, foods packed with sugars and soaked in omega-6 oils."

"There is but one answer to quieting inflammation," Lundell writes, "and that is returning to foods closer to their natural state." Don't eat anything your grandmother wouldn't recognize as food. He recommends eating protein and complex carbohydrates like colorful fruits and vegetables. He recommends abandoning concern about saturated fat, choosing olive oil or grass-fed meat or dairy as a better source of fat than high-omega-6 processed foods.

"Since we now know that cholesterol is not the cause of heart disease, the concern about saturated fat is even more absurd today," he writes. "Mainstream medicine made a terrible mistake when it advised people to avoid saturated fat in favor of foods high in omega-6 fats."

The thing is, like so many viral posts, this is a rerun. It's an old one. That's fine, except that learning it makes the "Today is the day" framing feel disingenuous. Lundell's same confession was also very popular when it was published on the website Prevent Disease in 2012. At that time it openly included a plug for his book, The Cure for Heart Disease, which made the same argument. That was published in 2007.

Lundell since came under fire from consumer advocate Dr. Stephen Barrett who runs the blog Quackwatch. In "A Skeptical Look at Dwight Lundell, MD," Barrett offers a profoundly skeptical look at Dwight Lundell, MD. Barrett digs into Lundell's past, which is fraught with legal issues including having his medical license revoked in 2008 on several counts of professional misconduct and negligence, issues with bankruptcy, and pleading guilty to three counts of willful failure to file income tax returns. Barrett concluded, "Dr. Lundell would like you to believe that he has special knowledge of heart disease prevention. I do not trust his advice."
