Meta study shows coffee protects against 6 different cancers

As if you needed another reason to drink more coffee …

Well, how about six?

Many people count on their java for a kickstart. But as it turns out, coffee can keep you healthier long after the caffeine wears off.

A new study published in the scientific journal Nature shows that drinking coffee can help protect against six different types of cancers.

This was the biggest meta-study (a "study of studies") ever done on the relationship between coffee and cancer.

The researchers reviewed data from 105 cancer studies and re-analyzed them.

Their studies showed that coffee intake can reduce the risk of oral/pharynx cancer, colon cancer, liver cancer, prostate cancer, endometrial cancer and melanoma by 31%, 13%, 54%, 11%, 27% and 11%, respectively. That’s for the highest vs. lowest coffee intake.

These new findings only add to growing evidence that supports the many health benefits of coffee.

The nation’s top nutrition panel released its newest dietary recommendations not long ago.

And the group did something it had never done before

It weighed in on whether people should drink coffee.

The Office of Disease Prevention and Health Promotion came out and said moderate coffee consumption can be part of a healthy dietary pattern.

One warning here, though, is to be careful that you’re not adding high-calorie and/or high-fat creamers and sugars to your daily brew.

So, coffee lovers can rejoice. Not only can you keep drinking it, but there are reasons to suggest you should … up to five cups a day.

"We saw that coffee has a lot of health benefits," said Miriam Nelson, a professor at Tufts University and one of the committee’s members. "Specifically, when you’re drinking more than a couple cups per day."

Now, perhaps it’s because I enjoy coffee myself that I commend the ODPHP for a long-overdue recommendation of coffee.

But the government agency forgot to say that not just any type of coffee will do.

To really take advantage of the many health benefits that coffee offers, remember that the quality of your coffee matters.

That means making sure you drink only the highest-quality, lowest-toxin java you can get your hands on.

What kind of coffee should you drink?

It’s important your coffee beans are of the highest quality. That means doing some homework to find producers that target the lowest toxin content possible.

Toxins can alter the flavor of your coffee. But worse, they can take away the positive health effects … and even produce negative ones.

Ideally, the beans should be harvested from a single family-owned estate. Preferably one located 1,200 meters (about three-quarters of a mile) or more above sea level. Many coffee connoisseurs say that’s high enough to produce top-quality coffee.

Altitude isn’t everything, though. The estate where the coffee beans are grown should also not allow chemicals. (Herbicides, pesticides, etc.)

The coffee beans should be handpicked by experienced coffee harvesters. Skilled people who know how to pick only perfectly ripe berries.

Getting back to flavor for a moment …

Most coffee beans are processed by leaving them in the sun and elements to wither and dry. Either that, or they get pressed and left to ferment (spoil) to remove the outer layer of the bean.

This can enhance the flavor, but it also lowers the quality. That’s because both techniques are known to produce significant levels of mycotoxins.

High-quality, low-toxin beans should be mechanically processed right after they’ve been picked … and using only clean, cold water.

This process is more-expensive than regular coffee processing. But it’s also safer. That’s because it dramatically reduces harmful molds or bacteria from impacting your health.

And finally, the beans should be roasted in small batches under the strictest conditions. Roasting the beans enhances their antioxidant capacity and flavor to provide you with a healthier, tastier cup of coffee.

Now, that may sound like a tall order to fill just to make sure you’re drinking the right kind of coffee.

That’s why I’ve already found for you what I believe to be the highest-quality, lowest-toxin beans on the market. Below are three brands I most recommend when it comes to sourcing your coffee beans:

  Upgraded Coffee

  Caveman Coffee

  Longevity Coffee

I have absolutely zero affiliation with any of these companies. I simply find them the best when it comes to bean quality.

We would love to know your favorite coffee brands, how you brew and any other fascinating details about your love for coffee. Leave us a comment with your favorite finds, too.

Just remember, sourcing your coffee beans is critical if you want to reap the many health benefits of coffee.

Happy and healthy investing,

Your thoughts on “Meta study shows coffee protects against 6 different cancers”

  1. Coronado Coffee is the specialty small batch roaster in the Southern New Mexico Sacramento Mountains with over 30 years experience. They ship their specialty gourmet coffees throughout the Western US for coffee consumers seeking the gold standard cup of coffee.

  2. I concur with the above comments on Starbucks, but I think it has to do with storage. I’ve had Starbucks in Seattle quit a few years ago and it was good, but when I tried it where I live in Tucson, I didn’t care for it. Probably has something to do with the temperature cycling it goes through in our warehouses. Therefore, I buy a local brand, Adventure Coffee Roasting ( and I’ve been happy with it.

    I think it is the local roasting that makes the difference, I purchase the coffee so that I consume it anywhere from 1 week to three weeks after it is roasted, you can’t do that with a national brand. Then again, this is from someone who probably gets a tad too obsessive about coffee taste.

  3. A few years ago I read somewhere (can’t recall where, but it seemed authoritative) that this advice to drink coffee applies to decaffeinated coffee as much as to regular. That would be important to people whom caffeine keeps from peaceful sleep (like my wife) or whose stomach linings are seriously irritated by repeated caffeine use (like me).

  4. Quote from your article: “And finally, the beans should be roasted in small batches under the strictest conditions. Roasting the beans enhances their antioxidant capacity …”

    That they have to be roasted is self evident, but that it has to happen in small batches is not the case. Why would that be? As long as the roaster can evenly distribute the temperature to the whole load all is well until the process is stopped at whichever colour you prefer after the second popping.

  5. I wonder if the study considered decaffeinated coffee. I drink both, as I can only take so much caffeine.

  6. I drink only Nestle’s Nespresso Ristretto, 1-3 daily, in a ristretto thimble-like server.
    Very intense. Great stuff. I assume Nestle’s coffees are top notch.

  7. Another source for absolutely great coffee is:
    Colorado Legacy Coffee (
    1048 Independent Avenue
    Grand Junction, CO 81501
    (970) 241-6558
    We are not affiliated but love their coffee and have it shipped to Indiana.

  8. My experience tells me that popular brands are amongst the least tasty. On a scale of 1 to 10 (10 being the best), I would rate Starbucks, for example, at around 6. Folgers would be near the bottom at around 2, so would be most other popular brands. I buy my coffee from the local grocery brand, med roast (Winn Dixie). It is inexpensive and tastes great. I do not roast or grind my coffee; too much hassle.

  9. This is very interesting to me, Brad, as a serious drinker, but not a connoisseur of coffee. I can’t stand Starbucks – I swear they put ashes in their brew. And while I’m also not a big fan of fast food, I’d rather have coffee from McDonald’s or Dunkin Donuts.

    Concerning your comments on the “highest quality, lowest toxin” coffee, I wonder how many of the life-long coffee drinkers involved in the study you cited drink that type of coffee as opposed to the Folgers, Maxwell House, and other standard brands? I would wager that it was very few if any. And so, the results suggest that most any coffee consumption leads to the health benefit. Wouldn’t you agree?
