New research has come to the conclusion that consuming higher levels of caffeine can help curb body fat and reduce the risk of type 2 diabetes.
The study was conducted by researchers at the University of Bristol and the Karolinska Institutet in Sweden and Imperial College London, which analyzed the genetic data of 9,876 individuals who participated in 6 different long-term studies.
The researchers specifically looked at the genes CYP1A2 and AHR, which affect the rate at which the body metabolizes caffeine. Those with the genes metabolized at a faster rate had lower BMIs.
The researchers also found that the same people had a lower risk of developing type 2 diabetes.
Study co-author Benjamin Wolfe, PhD, PhD, in the School of Psychological Sciences at the University of Bristol, said the findings support an observational association between caffeine consumption and reduced risk of type 2 diabetes.
Bradley Serwer, a physician not involved in the study, said: “Many studies have shown an association between caffeine and a reduced risk of obesity and diabetes, but this study takes the next step to show a causal association.”
In turn, Ahmed Ergin, an endocrinologist, said, “The benefits of caffeine must be weighed against the potentially dangerous side effects.”
He added, “Caffeine can have some potentially harmful side effects if abused and increased in amounts. Excessive consumption of caffeine can lead to insomnia, palpitations, and even behavioral problems.”
The UK Food and Drug Administration (FDA) recommends sticking to 400 milligrams of caffeine per day.
And this isn’t the first research highlighting the potential health benefits of caffeine.
Dr. Ergin said multiple studies have suggested links between coffee consumption and a lower risk of cardiovascular disease.
He added, “Research shows that those who consume three to five cups a day have a lower risk of heart disease and stroke compared to non-coffee drinkers.”
Great drink!
It is best to consult a doctor first before proceeding to increase the levels of caffeine you take on a daily basis, according to the study.
Dr Serwer said: “Like any drug, there are pros and cons that have to be weighed. One should consult and discuss the matter with their doctor, and although the results of this study may seem promising, there are no guarantees that people will lose weight or get away from diabetes once they have it. Increase their daily caffeine intake.
