Can Coffee Lower Cancer Risk? Surprising Preventive Effects Revealed by Latest Research and How to Choose Safely

I'm Kamei, owner of the premium mold-free coffee shop.

While you may hear that "coffee is good for your health," some of you might be concerned and wonder, "What about the risk of cancer?"

To answer directly, the International Agency for Research on Cancer (IARC), a subordinate organization of the World Health Organization (WHO), announced in 2016 that there is "no conclusive evidence that coffee consumption causes cancer," and furthermore, it may reduce the risk of certain cancers.

This time, we will explain in detail the relationship between coffee and cancer based on scientific data.


1. Scientifically Proven Preventive Effects on "Specific Cancers"

Research both in Japan and abroad, including by the National Cancer Center, suggests that regular coffee consumption may reduce the risk of developing certain cancers.

  • Liver Cancer: The most significant data has been found for liver cancer. Studies show that people who drink two or more cups of coffee per day have about half the risk of developing liver cancer compared to those who drink almost no coffee. This is thought to be because antioxidants like chlorogenic acid in coffee suppress liver inflammation.

  • Endometrial Cancer: A tendency for women who regularly drink coffee to have a lower risk of developing endometrial cancer has also been shown in Japanese domestic research (JPHC Study).

  • Colorectal Cancer and Prostate Cancer: In Western research, there have been successive reports on the reduced risk of colorectal cancer and prostate cancer.

2. The True Identity of Invisible Enemies That Hinder "Cancer Prevention"

While coffee has wonderful health benefits, there are two risks that we must never ignore.

① Carcinogenicity of Mycotoxins

Mycotoxins such as "aflatoxin" and "ochratoxin" produced from mold adhering to coffee beans are known as substances with strong carcinogenicity themselves. Even if you drink coffee for cancer prevention, if the beans are contaminated with mycotoxins, you are introducing toxins into your body, which negates the benefits.

② Acrylamide Formation

During the roasting process of coffee beans, a substance called "acrylamide" is formed. This is also one of the substances suspected of being carcinogenic, but it is generally understood that if coffee is properly extracted, its content is not at a level that affects health.

3. For a Worry-Free Cancer Prevention Habit: The Role of Mold-Free Coffee

Our thorough quality control is precisely for the purpose of "maximizing benefits and minimizing risks."

  • Mycotoxin Testing by Third-Party Organizations: We scientifically prove "non-detection" to thoroughly eliminate the intake of carcinogens.

  • Thorough Hand-Picking: By manually removing defective beans (moldy beans and unripe beans), we eliminate not only off-flavors but also health concerns.


Summary: Choose Wisely for a Lifelong Healthy Habit

If chosen correctly, coffee can be a powerful ally in reducing cancer risk.

However, inexpensive beans with unclear management may harbor invisible risks. Precisely because this generation wishes to cherish their future health even more, choosing "tested, clean beans" is the best investment in themselves.

A clear cup with no worries. We hope you will enjoy its aroma and taste while nurturing your health 10, 20 years from now.
