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.

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.

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.
