Beef Liver for Energy: 8 Science-Backed Reasons It May Help Reduce Fatigue

Beef liver is one of the most nutrient-dense foods on the planet and may help support natural energy levels. In this article, we break down eight science-backed reasons beef liver supports energy production — including heme iron, B vitamins, CoQ10, choline, and other key nutrients involved in metabolism, oxygen transport, and brain function.

Kineon Move+ Pro Review: Red Light Therapy for Joints and Recovery

I tested the Kineon Move+ Pro for several months to see if targeted red light therapy actually supports joint pain and recovery. In this science-based review, I break down the 660nm and 808nm wavelengths, pulse wave technology, LEDs vs lasers, and who this device is best for. Here’s what I noticed — and what the research says.

Are Humans Meant to Drink Cow’s Milk?

Dairy is one of the most controversial foods in modern nutrition. In this evidence-based deep dive, we examine whether humans are actually meant to consume cow’s milk, how dairy has been used throughout human history, what lactose intolerance really means, and why raw and traditionally produced dairy behaves very differently than modern processed milk.

11 Dietary Principles All Healthy Cultures Have in Common

Modern nutrition advice changes every decade — but human biology hasn’t. Across continents, climates, and thousands of years, the world’s healthiest cultures shared the same foundational foods. In this article, we explore the foods all thriving cultures had in common, why they worked so well with human physiology, and how modern diets drifted away from these principles — especially with the rise of ultra-processed foods and seed oils.

The Dark History of Canola Oil: Is This “Heart‑Healthy” Fat Actually Healthy?

Canola oil is widely marketed as a heart-healthy fat, yet its origins as an industrial lubricant and extreme processing raise serious concerns. This evidence-based breakdown explores how canola oil is made, why it lowers LDL cholesterol, what early research actually found, and whether oxidation—not cholesterol alone—may be the real driver of cardiovascular and metabolic disease.

Are Seed Oils Actually Toxic? The Science Behind Oxidation, LDL, and Chronic Disease

Seed oils are often promoted as heart-healthy because they lower LDL cholesterol — but that’s only part of the story. This evidence-based breakdown explores how seed oils contribute to oxidation, toxic byproducts, and long-term metabolic stress, and why focusing on LDL alone may miss the real drivers of chronic disease.

The Blue Zones Were Never Plant-Based: What These Long-Lived Cultures Actually eat

Blue Zones are often used as proof that humans thrive on a plant-based diet — but the real story is far more nuanced. When you look at anthropology, traditional food prep, and the actual diets of long-lived cultures, you’ll find meat, dairy, and properly prepared plants all play a role. Here’s what the Blue Zones really ate — and what we should actually learn from them.

Why Whole30’s Decision to Approve Seed Oils Is a Serious Mistake - And What the Science Actually Shows

Whole30 recently announced that seed oils are now permitted in their program, claiming that “the science has changed.” This article takes a deep dive into the research Whole30 cited—and the science they left out. We examine why focusing only on LDL cholesterol and short-term inflammation markers misses the bigger picture, how linoleic acid and oxidized fats behave in the human body, and why long-term exposure to seed oils may carry metabolic and cardiovascular risks that deserve serious consideration.

Eggs Aren’t the Enemy: The Truth About Cholesterol, Saturated Fat, and Choline

Eggs have been demonized for decades — blamed for high cholesterol, clogged arteries, and even “dangerous” compounds like TMAO. But the science tells a very different story. Here’s what decades of research (and updated dietary guidelines) actually say about eggs, cholesterol, saturated fat, and why egg yolks may be one of the most nutrient-dense foods you can eat.

Are Vegan Diets Really Healthier? A Scientific Breakdown of Netflix’s You Are What You Eat

Netflix’s You Are What You Eat: A Twin Experiment claims a “healthy vegan” diet outperforms an omnivorous diet — but the real story is more nuanced. In this evidence-based breakdown, I walk through what the Stanford identical-twin trial actually measured (and what it didn’t), how to interpret LDL vs HDL/triglycerides, and why short-term results don’t automatically translate to long-term health outcomes.
