The Fruit That 35 Million Dollars Could Not Prove

One family spent a fortune studying the pomegranate. Here's what held up, what fell apart, and what the federal government had to say about it.

The pomegranate turns up everywhere in old stories. Persephone eats the seeds and gets stuck in the underworld. Leaves from the tree sat on the coffin of Tutankhamun.

Then one American family got interested. They spent more than 35 million dollars funding research on it.

What came out of all that money is a good lesson in how to read a health claim.

Let me lay it out…

First, The Seed Myth

You may have heard that every pomegranate holds exactly 613 seeds. The number matters in Jewish tradition, since it matches the count of commandments.

Somebody actually checked. A Columbia University graduate student named Alexander Haubold counted the seeds in 206 pomegranates.

The average came out at 613. Lovely. But individual fruits ran anywhere from 165 seeds to 1,370.

So the average is a nice coincidence. The rule is not true of any single fruit you'll buy.

What's Actually In One

Half a cup of the seeds, about 87 grams, gives you 72 calories.

You also get 3.5 grams of fiber, 205 milligrams of potassium, and a small amount of vitamin C, per USDA data.

Those numbers come with a catch, and the catch is juice.

Press pomegranates into juice and the fiber is gone. USDA lists 4 grams per 100 grams in the seeds and 0.1 grams in bottled juice.

Vitamin C mostly disappears too. A glass of juice carries around 31 grams of sugar, which is soda territory.

Eat the seeds. Chew them, because the crunchy bit inside each one is where the fiber lives.

The Small Study Everyone Quotes

Here's where the money comes in.

Michael Aviram at the Technion in Israel ran a study on people with narrowed neck arteries. Ten of them drank pomegranate juice daily. Nine did not.

After a year, artery wall thickness had dropped in the juice group. In the comparison group it had gone up 9 percent. The paper ran in 2004 in Clinical Nutrition.

That result got quoted everywhere. It's also 19 people, with no placebo and no blinding.

Then Somebody Ran The Big One

A proper trial followed. Michael Davidson and colleagues randomized hundreds of people to pomegranate juice or a placebo drink, for up to 18 months.

Two hundred eighty-nine of them completed it. Same measurement, the thickness of the artery wall.

The answer was no. No meaningful difference between the juice group and the placebo group. Published in 2009 in the American Journal of Cardiology.

One more detail. That trial was funded by the parent company of the biggest pomegranate juice brand in America.

They paid for a real test, and the real test came back empty.

So What Does Hold Up

Blood pressure, modestly.

Amirhossein Sahebkar and colleagues pooled eight trials in 2017. Pomegranate juice lowered the top blood pressure number by about 5 points, and the bottom number by about 2.

That's a real effect, and a small one. It's also the most defensible claim anyone can make about this fruit.

THE FINDING: A 2017 review in Pharmacological Research pooled eight trials of pomegranate juice. Systolic blood pressure fell by about 5 points and diastolic by about 2. That modest blood pressure effect is the best-supported claim for pomegranate. The larger claims about arteries and cancer did not survive proper testing.

The Part With Lawyers In It

In 2006, a team at UCLA gave pomegranate juice to men whose prostate cancer markers were climbing. The markers slowed down.

That study had no control group. Everyone got the juice, so there was nothing to compare against.

A randomized version came later, published in 2015. Against placebo, pomegranate extract made no significant difference.

Meanwhile the marketing had gotten ahead of the science. The Federal Trade Commission went after the company in 2010 over its health claims.

The case ran for years. A federal appeals court upheld the core of it in 2015, and the Supreme Court declined to hear it in 2016.

Money bought a lot of studies. It did not buy the results the ads promised.

Why I Still Eat Them

None of this makes the pomegranate a bad food. It makes it a food.

Fiber, potassium, a bit of vitamin C, a real if small blood pressure effect, and a fistful of polyphenols.

That's a good fruit. It just isn't a medicine, and it never needed to be one.

Three Things Worth Knowing

Open It Underwater

Score the skin into quarters, then break the fruit apart in a bowl of water. The seeds sink and the white membrane floats, and none of the juice ends up on your shirt.

Choose The Fruit Over The Bottle

Juice loses nearly all the fiber and the vitamin C, and a glass carries about 31 grams of sugar. The seeds cost more effort and give you far more.

They Don't Ripen After Picking

What you buy is as ripe as it gets. Pick heavy fruit with taut skin, and keep it in the fridge, where a whole pomegranate holds for up to two months.

Here's What I'd Do This Week

Buy one whole pomegranate. Open it underwater over the sink.
Eat the seeds, crunch and all. That's where the fiber is.
Skip the juice as a daily habit. It's a sugary drink with the fiber removed.
Ignore anyone selling it as cancer protection. The randomized test came back negative.

A tiny study said one thing. A big study said another. Guess which one made it onto the label.

The pomegranate is worth eating anyway. Just eat it as fruit, not as a promise.

Open one this week. Watch the seeds sink.
