Pomegranate
A cup of pomegranate juice most days lowers your blood pressure about five points, roughly what a starting dose of an ACE inhibitor does Ghaemi et al. 2023. That one modest effect is the entire honest claim. The fifteen years of marketing that had it reversing arterial plaque, preventing prostate cancer, and treating erectile dysfunction collapsed under placebo-controlled trials and a Federal Trade Commission ruling. What's left is a tasty fruit with one small, replicated heart benefit, worth a slot in a good diet.

The blood-pressure drop is the one piece that held up. Two pooled reviews land the same answer: about a cup a day drops systolic pressure roughly five points and diastolic about two, within a few weeks, with no extra benefit past 300 mL 1 2.

The dramatic claims came from small early trials that bigger ones erased. Daily juice was reported to shrink artery-wall thickening; the larger, longer replication found no difference 3. Juice seemed to slow rising PSA in 50 men with no control arm; the placebo-controlled version in 183 men made juice and placebo indistinguishable 4.

The active compound isn't the one you taste. Pomegranate is loaded with plant compounds called ellagitannins. Your gut bacteria convert them into urolithin A, the molecule that actually circulates. Separately, the polyphenols partially block the same enzyme a whole class of blood-pressure drugs targets, which is where the five points come from 5.

Five points sounds like nothing; the arithmetic says otherwise. You won't feel it and nobody will notice it. But a sustained five-point-lower systolic across a decade maps to roughly 10% fewer coronary deaths and 13% fewer stroke deaths at the population level. It's one small protective factor stacked on top of the things that move your heart far more: salt, weight, sleep, exercise, and a statin if you're on one.

Eat the fruit, not the bottle, and let your home cuff decide.

Within a month: your cuff reads about five points lower on top, two lower on the bottom. 138/88 becomes closer to 133/86. You feel exactly the same. No energy lift, no skin change, no head-clearing.

Years out: you've added one silent protective factor to a longer cardiovascular trajectory, on the order of a low-dose blood-pressure drug claimed back as a fruit. The reward isn't a felt experience but an actuarial one, and you don't get to know which version of you avoided the event.

The fine print β€” when to skip it, and what people get wrong

Only about 40% of adults carry the gut bacteria that make urolithin A, and the split worsens with higher body weight 6. The blood-pressure effect skips that pathway, so the cuff is still your test.

Warfarin: juice can prolong your INR; tell your clinic first. On a BP drug: stacking five points can cause dizziness; monitor a month. Type 2 diabetes: eat arils, skip juice. Kidney disease stage 3+: a cup carries about 590 mg potassium.

The FTC ruled POM Wonderful's disease claims unsupported, upheld on appeal in 2015 7. And not all juice is equal: some "100% pomegranate" blends carry a quarter of the active compound, doing nothing.
