Seed Oils: The Honest Case Against Them

Industrial seed oils — soybean, canola, corn, sunflower, safflower, grapeseed — went from near-zero in the human diet to the single most-consumed fat on Earth in about a century, and I don’t think that experiment has gone well.

Is Dairy Actually Bad for You? The Evidence

Few foods carry a reputation as lopsided as dairy’s. It gets blamed for inflammation, acne, weak bones, heart disease, and a throat full of mucus — a list long enough that plenty of otherwise-healthy people quietly cut it and never look back.

Meditation: What the Evidence Actually Shows

Meditation is one of the rare wellness practices with a genuine evidence base — and one of the most aggressively overhyped. The two facts sit uncomfortably together.

Is Sitting Really the New Smoking?

“Sitting is the new smoking” is one of the stickiest health slogans of the last decade — short, alarming, and repeated everywhere from morning television to standing-desk ads.

Is Loneliness as Deadly as Smoking?

It is one of the stickiest statistics in modern public health: loneliness, we are told, is as deadly as smoking fifteen cigarettes a day.

Sauna & Longevity: How Strong Is the Evidence?

Few wellness habits arrive with numbers this eye-catching. In a long-running cohort of middle-aged Finnish men, those who used a sauna four to seven times a week had roughly half the risk of dying from heart disease — and a lower risk of dying from anything…

Is Moderate Drinking Actually Healthy?

For thirty years you were told a glass of red wine a night was practically a cardiac supplement — that moderate drinkers outlived teetotallers, that a little alcohol was heart-protective, that abstaining was almost the risk.

Hearing Aids & Dementia: What the Trial Showed

In the most influential model of dementia prevention we have, one risk factor sits at the very top of the modifiable list — ahead of smoking, high blood pressure, obesity, and physical inactivity. It is not what most people would guess. It is hearing loss.

Grip Strength & Longevity: Marker or Lever?

Few numbers in medicine punch above their weight like grip strength. A cheap spring gauge you squeeze for a couple of seconds turns out to forecast your risk of dying — from anything, and from heart disease specifically — across studies spanning seventeen c…

Coffee and Longevity: Does It Help You Live Longer?

Few habits have a research file as flattering as coffee’s. Across enormous prospective cohorts on multiple continents, people who drink moderate amounts — roughly two to four cups a day — die at lower rates than non-drinkers, and carry lower risk of cardiov…

Sauna and Cold Contrast Therapy: Worth It?

Sauna to cold plunge and back again has become the recovery ritual of choice, sold with a tidy story about a vascular “pump” that flushes your muscles clean. The honest evidence is more interesting than the pitch.

Forest Bathing: Is Shinrin-Yoku Real Medicine?

Walk slowly through a forest, breathe, put the phone away, and something measurable happens: your cortisol drops, your blood pressure eases, your nervous system shifts out of fight-or-flight. That part is real, and the meta-analyses back it.

Rucking & Weighted Vests: What the Evidence Says

Strap weight to your back and walk, and you have done something deceptively simple: you have turned an easy aerobic activity into a harder one without changing your pace, your route, or your knees-on-pavement risk profile.

Hydrogen Water: Worth It or Expensive Water?

It is sold in $400 bottles and dissolving tablets, marketed for energy, recovery, skin, and almost everything else. There is a real, if early, science here — and then there is the marketing. Here is the honest line between the two.

The calories-in-calories-out model was never wrong — it was just incomplete. A 2026 network meta-analysis and a confirmed NYU Langone randomized trial now say the same thing: when you eat matters as much as how much.
