Previous research shows that drinking three to five cups of coffee a day may reduce the risk of heart disease and type 2 diabetes. An average cup of coffee contains 70-150 mg of caffeine.
In the new study, researchers used Mendelian randomization to understand how high blood caffeine levels affect body fat and the risk of type 2 diabetes, stroke, coronary heart disease, heart failure, and irregular heart rhythms.
Experts examined the role of two common genetic variants, CYP1A2 and AHR, in about 10,000 people. These people were mostly of European descent. They were also involved in six long-term studies. It is known that the CYP1A2 and AHR genes are responsible for the caffeine metabolism rate in the body.
According to the results of the study, higher genetically predicted caffeine levels in the blood were associated with lower weight (body mass index), less body fat, and a lower risk of developing type 2 diabetes.
They also found that the 43% increase in weight loss increased the effect of caffeine on the risk of developing type 2 diabetes.
When it comes to blood caffeine levels and heart disease risk, no strong associations were found between the two.
In addition, caffeine itself is known to accelerate metabolism, increase fat burning and reduce appetite. With a daily intake of 100 mg of caffeine, energy expenditure increases by about 100 calories per day. Accordingly, it can reduce the risk of developing obesity.
