[Asia Economy Reporter Seohee Lee] A study has found that drinking just one cup of coffee a day can reduce the risk of death from various diseases, including cardiovascular disease, by 25%.

On the 30th, the Korea Food Communication Forum (KOFRUM) announced that Professor Jeong-eun Lee's team from the Department of Food and Nutrition at Seoul National University analyzed the relationship between coffee consumption and mortality rates from various diseases among 192,222 participants in the Korea National Health and Nutrition Examination Survey and the Korean Genome Epidemiology Study, yielding these results.

The research team tracked 37,281 participants from the National Health and Nutrition Examination Survey for an average of 7.7 years and 154,941 participants from the Genome Epidemiology Study for an average of 9.7 years.

During this period, there were 6,057 deaths, including 1,473 from the National Health and Nutrition Examination Survey participants and 4,584 from the Genome Epidemiology Study participants.

Analyzing the relationship between their deaths and coffee consumption, coffee intake contributed to lowering mortality rates from multiple diseases such as cardiovascular and respiratory diseases. Specifically, drinking just one cup of coffee a day reduced the mortality rate by 25% compared to those who did not drink coffee.

Drinking 1 to 3 cups of coffee a day reduced mortality rates from cardiovascular disease, respiratory disease, and diabetes by 20%, 32%, and 47%, respectively, compared to non-coffee drinkers.

The research team stated, "The reason coffee lowers mortality rates is still unclear," and estimated that "bioactive substances in coffee such as chlorogenic acid, caffeine, trigonelline, and melanoidin may have antioxidant and anti-inflammatory effects and improve blood sugar levels, which could be the key to reducing mortality rates."
