On changing your mind about food

A short history of dietary certainty, and what the pattern of reversal teaches

The past four decades have produced a series of public reversals on dietary fundamentals. Saturated fat, dietary cholesterol, eggs, salt, red meat, low-carb diets, seed oils. Each was confidently declared dangerous, then re-evaluated, sometimes reversed. The pattern of reversal is itself the lesson.

The lectin question, examined

Steven Gundry, The Plant Paradox, and what to make of a popular thesis the field has rejected

Gundry argues that lectins — a class of plant proteins — are responsible for chronic inflammation, autoimmune disease, and obesity. The book has sold millions; the mainstream nutrition community has dismissed it. A closer look at where the argument is right, where it falls apart, and why elimination diets keep producing apparent results.

The morning protocol industrial complex

What the evidence actually supports, and why the format keeps spreading

A genre has emerged in which a successful person describes their twelve-step morning routine and the audience is invited to copy it. The interesting question is not whether the protocols work — some do, some don't — but why the format itself has become the thing.

"Science is fifteen years behind" — separating the real from the rhetorical

Translation lag is a real phenomenon. It is also the most common defence used for unsupported claims.

A rhetorical move common in wellness discourse: mainstream medicine is decades behind what is already known, and current critique can be dismissed as a temporary lag. The phenomenon is real. The deflection is mostly not. Distinguishing the two is one of the more useful skills available.

The blue light glasses question, examined

Lab findings, RCT results, and where the popular advice goes wrong

The blue light glasses market is large and growing. The premise — that filtering short-wavelength evening light prevents melatonin suppression and protects sleep — is half-supported by the laboratory research and contradicted by the real-world trials. The science is real. The product is mostly not what the science is about.

Does TV really "eat your dopamine"?

What the neuroscience says about passive consumption and reward, and where the slogan overreaches

The claim that television "depletes dopamine" has spread from Lembke and Huberman into general health discourse. The underlying neuroscience does not say what the popular version claims it says. The behavioural concerns about passive consumption are real, and largely independent of dopamine.

You are not the average of the five people you spend the most time with

The Jim Rohn quote, the Christakis findings, and what social-influence research actually says

A well-loved aphorism with the rhetorical force of a research finding. The actual research on social influence is real, more modest in its claims than the popular framing, and tangled with a confound the slogan does not acknowledge.

The rapid skill acquisition claim, examined

Ericsson, Kaufman, and what "twenty hours" does and doesn't get you

Josh Kaufman's argument that any skill can be acquired in 20 hours pushed back usefully against the popular misreading of Anders Ericsson's expertise research. It also overcorrected. What 20 hours actually buys, and where the "creativity over facts" framing breaks down.
