Is Coffee Good For You ? Drinking three cups a day could help reduce the risk of diabetes and stroke

Trois tasses de café par jour pourrait contribuer à réduire le risque de maladies cardiométaboliques.

Regular consumption of coffee and caffeine in moderate amounts may have a protective effect against the development of multiple cardiometabolic diseases, including type 2 diabetes, coronary heart disease and stroke.

Obesity, diabetes, cardiovascular disease, fatty liver disease… The increase in the number of people with cardiometabolic diseases worldwide is becoming a public health concern. Worse, with the aging of the population, many people suffer from several pathologies, what is called cardiometabolic multimorbidity.

"People with a single cardiometabolic disease may have a risk of mortality from all causes twice as high as those who do not suffer from it", explain scientists from Soochow University (Taiwan). "And those with cardiometabolic multimorbidity may have an almost 4- to 7-fold increased risk of all-cause mortality."

The emphasis should therefore be on prevention in order to prevent these diseases from developing. While many studies have shown the protective effects of coffee, tea, and caffeine consumption on the morbidity of single cardiometabolic diseases, the potential effects of these beverages on the development of multiple pathologies have been largely unknown.

A combination of benefits

To fill this gap, the Taiwanese researchers relied on the UK Biobank, a large study of the diet and health data of more than 500,000 participants aged 37 to 73.

Result: “Coffee and caffeine consumption (decaf does not count, ndlr) at all levels was inversely associated with the risk of developing cardiometabolic multimorbidity.” Specifically, “consuming three cups of coffee, or 200 to 300 mg of caffeine per day, could help reduce this risk“.

What mechanisms ?

While the authors do not specify the nature of the protective effects of coffee, a complete review of its benefits, conducted last July, revealed “a complex interaction of antioxidant, anti-inflammatory, lipid-modulating, insulin-sensitizing effects… These mechanisms collectively contribute to reducing the risk of a spectrum of adverse cardiometabolic outcomes, including hypertension, metabolic syndrome, type 2 diabetes, cardiovascular disease, and all-cause mortality“.
