When Influencers Replace Scientists, Everyone Loses Every few years, nutrition gets a makeover. First comes a new graphic. Then comes a new slogan. Soon after, we hear claims that this time, someone finally figured it all out. Recently, that makeover arrived in the form of a “reverse food pyramid” and the cheerful phrase “Eat Real Food.” On the surface, that message sounds reasonable. In fact, many doctors have said the same thing for decades. However, the real problem isn’t the slogan. Instead, the problem lies in who is now shaping nutrition advice—and who is not.
Yes, Some of the Advice Is Right To be clear, let’s start with agreement. Eating real food helps health. Limiting added sugar makes sense. Reducing ultra-processed foods improves outcomes. Importantly, none of this is new. Doctors, dietitians, and public-health researchers have said these things for years. Because of that, when influencers now say, “See, we were right,” a serious issue appears. They didn’t discover this information. They copied it.
The Real Risk Isn’t Agreement At first glance, agreement sounds harmless. Nevertheless, agreement becomes dangerous when it turns into ownership. Once someone believes they have discovered basic nutrition truths, they often assume they can rewrite everything else. As a result, bad ideas slip in quietly, wrapped in confidence instead of evidence. That shift matters.
Scientists and Influencers Are Not Interchangeable At this point, we need to say something clearly. We cannot afford to replace scientists with influencers. Nutrition science didn’t come from podcasts or social media. Instead, it came from metabolic ward studies, long-term population research, and randomized trials. Moreover, real scientists accept uncertainty. They change their minds when the data changes. By contrast, influencer culture rewards certainty. Even worse, confidence often replaces humility. There is no “Mediterranean diet influencer community.” Likewise, there is no “DASH diet movement.” Those dietary patterns exist because scientists studied them, tested them, and measured outcomes over time. On the other hand, a loud low-carb and carnivore influencer ecosystem does exist. That ecosystem includes brands, supplements, coaching programs, and a strong contrarian identity. Because of that structure, influence—not evidence—often drives the message.
Fiber Versus Saturated Fat: A Telltale Sign If you want to know whether someone understands nutrition science, ask a simple question: Which matters more—fiber or saturated fat? Influencers often say, “Fiber isn’t an essential nutrient.” Technically, that statement is true in the narrowest sense. However, context matters. Fiber supports a healthy gut microbiome. Additionally, fiber improves insulin sensitivity. Furthermore, fiber lowers cardiovascular risk. Finally, fiber supports colon health. Because fiber feeds beneficial gut bacteria, entire fields of microbiome research depend on it. Now compare that with saturated fat. Saturated fat is truly non-essential. Your body can make all it needs. No deficiency disease exists from avoiding it. Even more importantly, excess saturated fat raises LDL cholesterol and worsens artery health. Over time, that increases cardiovascular risk. So ask yourself this: Why dismiss fiber as optional while quietly promoting saturated fat? That choice reflects ideology, not biology.
The Brain Doesn’t Care About Trends Here’s another reality check. Your brain—the most important organ you own—relies heavily on polyunsaturated fats. These fats support cell membranes, nerve signaling, and blood flow. Ironically, these same fats often get labeled “seed oils” and dismissed. Meanwhile, saturated fat does not belong in high amounts in brain tissue. Worse still, saturated fat can clog the arteries that supply the brain. Biology does not respond to marketing. Physiology does not care about popularity.
The “You’re On Your Own” Problem Another issue deserves attention. After influence

With all the spices we have access to, it is amazing how bland recipes have become. I have many cookbooks, some from great chefs, television personalities, and friends. What I am always surprised by is how bland the food has become. People seem to think a bit of salt, pepper, maybe onions, and garlic provide the spices one needs. Perhaps it is because some associate spice with heat. Mostly because many have never experimented with some of those great warm spices available. A pinch of coriander, some freshly ground cumin, a little cardamom, or a touch of cinnamon can turn an ordinary dish into something remarkable. And the most astonishing part is that these spices financed voyages around the world, built cities, created fortunes, and caused people to kill one another. Without the spice trade, it is safe to say that the United States, as we know it, would be vastly different from what it is now. The money loaned to the United States, when we were a fledgling country, came from the wealthy spice merchants from what was considered one of the great hyperempires of the world, based in Amsterdam. But before we go to the birth of the United States, let me take you to the meatball.

MesoAmerica and Chocolate In our series looking at foods that built civilizations, today we are going to stay in the Americas with chocolate. Chocolate has been used as currency, consumed by kings, incorporated into religious ceremonies, and prescribed as medicine. Today, it is a multibillion-dollar industry that wants you to believe that eating chocolate is an act of preventive cardiology. I mean, why not? They convinced us to give chocolate to people we love, eat it when we are happy, when we are sad, when only the dog understands us. Don’t feed chocolate to your dog. And we have done all this with a bitter seed that most of us would probably spit out if we tasted it straight from the tree.
I’ve been doing a series about foods that built civilizations. In this episode, we are talking about the potato. It is difficult to imagine that thousands of years ago, people constructed large buildings, managed rivers, built monuments, and created art. We have glimpses of these civilizations through stories, archaeology, and the structures they left behind, but much of their history has been lost. Imagine, we don’t even know where Cleopatra or Alexander the Great are buried, yet we know their stories. As European powers conquered Indigenous peoples, their languages, cultures, and oral traditions were suppressed. When a language disappears, so are the stories preserved within it. Our clues come from archaeology when we uncover a monument, a building, or an ancient settlement. In the Andes, the potatoes they cultivated were not the Russets, Yukon Golds, or fingerlings you find in the store today. Different colors, shapes, and textures. Adapted to survive the elevations, temperatures, and growing conditions. Biodiversity protected their food supply against frost, disease, and changing environmental conditions. If one variety failed, another might survive. The ancient wisdom of diversity that Andean farmers developed over thousands of years was lost when the potato eventually reached Ireland.
In our series about foods that built civilization, we talked a lot about grains, from wheat to corn to rice. Today, we are taking you to the ocean, with the civilizations that salmon built. From California to the interior of Alaska, salmon, a staple, allowed people to settle into villages, develop complex social networks, art, and trade routes. Those trade routes are as large as the ones in the Mediterranean. Some tribes built communal homes and developed complex art and language. Some were Seafaring tribes with canoes up to 60 feet long that traveled across oceans. All because there was a fish that would return in large numbers to streams and rivers, reliably, predictably. So predictable, the people could build their lives around salmon runs. So much so that some built a calendar not only with lunar cycles, but also with the return of the salmon. Civilizations have always gathered around food and water. The Mediterranean connected people who grew wheat and olives, giving people time to make wine, mine copper, build ships, trade with their neighbors, and occasionally go to war with them. Asia had rice and grain near the great river systems. The reliable calories from rice and grains allowed villages to become cities and to travel by water to trade. Today we are going to my home, from the Ventura River in California to my home state of Alaska.
