That morning cup of coffee might provide more benefits than just a quick energy boost. New research suggests that consuming higher levels of caffeine could help curb body fat and reduce the risk of developing type 2 diabetes. Drinking coffee daily can also extend your life according to the study.
Analyzing genetic data from 9,876 European individuals who participated in six different long-term studies, the researchers specifically monitored the CYP1A2 and AHR genes, which influence the rate at which the body will metabolize caffeine. Those who had genes that metabolized caffeine at a faster rate were associated with having a lower body mass index (BMI) and lower whole body fat mass. They were also found to have a reduced risk of type 2 diabetes.
The benefits should be weighed against its potentially dangerous side effects. The Food & Drug Administration (FDA) recommends sticking to 400 milligrams of caffeine per day. That’s equivalent to about four to five cups of coffee, but different people react differently to caffeine depending on their metabolism, tolerance and sensitivity.
While it has been linked to a bevvy of benefits, it is still a stimulant. People who are at risk for cardiac and psychiatric disorders — such as insomnia, mania or bipolar disorders may not tolerate the drug and may face adverse effects.
