Last Updated: 2026/02/24, A previous Greek study found that drinking coffee for a long time can reduce the risk of diabetes, while a recent Swedish study said that drinking coffee can help reduce the risk of breast cancer in addition to its refreshing effect. Swedish researchers surveyed 40000 women for 20 years about their daily diet, including daily coffee, according to British media reports quoted by Taiwan's China Times on July 28.

According to Taiwanese media, a previous study found that long-term consumption of coffee can reduce the risk of diabetes, while a recent study in Sweden suggested that drinking coffee not only has a refreshing effect, but also helps reduce the risk of breast cancer.

Swedish researchers conducted a 20-year daily diet survey of 40000 women, including the amount of caffeine in coffee and tea, and found that women who drank more than five cups of coffee a day had a 19% lower risk of breast cancer than those who drank one or two cups a day, according to British media reports.

However, the survey also found that women who had more than one cup of tea a day had a 19% increase in breast cancer compared with women who did not touch tea at all. It has been learned that this research report has been published in the International Journal of Cancer (International Journal of Cancer).

The researchers said that the study that "coffee helps reduce the risk of breast cancer" may have something to do with the antioxidants in coffee, which can effectively protect cells and prevent cancers from becoming cancerous.
