Most Blood Pressure Readings Are Wrong # A cuff two sizes too small adds nearly 20 mmHg. An unsupported arm adds almost 7. A full bladder adds 10 to 15. Stack a few of those and you have a diagnosis of hypertension manufactured entirely by technique. Why this matters in both directions # High blood pressure is the largest single contributor to strokes and heart attacks worldwide, and it produces no symptoms until it produces a catastrophe. That makes measurement genuinely important — and it makes measurement error important too, in both directions.
No Vegetable Unclogs Anything # Nothing you eat clears an artery the way a plumber clears a drain. But three categories of vegetable, eaten consistently for years, measurably slow arterial ageing, keep existing plaque more stable, and lower blood pressure in controlled trials. That’s a smaller claim and a far better supported one. Third: cruciferous vegetables # Broccoli, cauliflower, cabbage, kale, Brussels sprouts. People eating these regularly show less calcification and hardening in artery walls — the kind visible on an X-ray as faint parallel lines tracking a vessel, and conspicuously absent in people with healthy arteries.
Ten Minutes After Dinner Beats Thirty Minutes Whenever # Same shoes, same thirty minutes, same person. Split it into three ten-minute walks straight after meals instead of one block at a convenient hour and postprandial glucose drops about 12% — and 22% after the evening meal. The variable that changed was timing. The trial that isolates timing # Reynolds et al. (2016, Diabetologia) ran a randomised crossover study in adults with type 2 diabetes, comparing advice to walk 10 minutes after each main meal against advice to walk 30 minutes a day without specified timing. Total walking was held equal.
