Coffee Contains More Polyphenols Than Tea

You’ve heard red wine and dark chocolate fight heart disease—but what if your morning coffee does even more? A major Japanese study reveals that the polyphenols in your daily cup rival those in wine, and you’re likely getting most of your daily dose without realizing it.

Coffee packs 200mg of polyphenols per 100ml—nearly matching red wine’s average (230mg) and beating green tea (115mg). Japanese researchers found it’s your top source of these heart-protective compounds.

What Are Polyphenols—and Why Do They Matter?

Polyphenols are plant compounds linked to lowering artery-hardening risks. Found in red wine, cocoa, and now coffee, they’re a key reason these drinks are tied to cardiovascular benefits. The focus here: how much you actually get from your daily routine.

Coffee vs. Wine vs. Tea: The Polyphenol Breakdown

Researchers measured polyphenol content per 100ml: red wine ranges 150–300mg (average 230mg), coffee hits 200mg, and green tea sits at 115mg. That means your post-meal coffee delivers comparable—or higher—antioxidant levels than a glass of wine.

How Much Polyphenol Are You Really Getting?

In a survey of 9,000 people (with detailed data from 109), researchers found 80% of daily polyphenols come from beverages, not food. Of those drinks, half the polyphenols come from coffee. That’s your biggest source, far ahead of tea or wine.

Why Japan’s Heart Health Might Link to Coffee

The study notes Japan has the world’s lowest rate of heart attacks from arterial sclerosis and the highest life expectancy. While tea’s polyphenols contribute, coffee—now shown to deliver even more—might be a key factor in that health profile.

Frequently Asked Questions

How many milligrams of polyphenols are in 100ml of coffee?

Coffee contains 200mg of polyphenols per 100ml, as measured in the Japanese study. This is nearly equivalent to red wine’s average of 230mg and significantly higher than green tea’s 115mg per 100ml.

What percentage of daily polyphenols come from coffee?

Does green tea or red wine have more polyphenols than coffee?

No. Coffee has 200mg of polyphenols per 100ml, which is higher than green tea’s 115mg and roughly equal to red wine’s average of 230mg (ranging 150–300mg depending on concentration).

Why is polyphenol intake important for health?

Polyphenols are linked to reducing the risk of arterial sclerosis and supporting cardiovascular health. Regular intake from sources like coffee, wine, and tea may contribute to lower heart disease rates.

Is coffee the best drink to replace tea for polyphenols?

If you’re looking for a beverage to match or exceed tea’s polyphenol content, coffee is the top choice. It provides more polyphenols per 100ml than green tea and similar levels to red wine.
