Researchers believe caffeine is in your blood

Scientists have always believed there was a link between caffeine consumption and genetics. An article on ABCnews claims that researchers have found the genes which actually do it. The genes were CYP1A2 and AHR. The researchers believe this will allow them to study the effects of caffeine on our bodies. The study analyzed 47,000 middle-aged Americans. A sizeable study which resulted in a positive correlation between carriers of the gene and the high intake group of caffeine consumers. The study found that 9 out of 10 Americans consume caffeine regularly. The difference between the high-intake and low-intake group was 40 mg of caffiene per day. It does not say if that difference occurs as the difference between one cup of coffee and one and a third cups or eight cups of coffee and eight and a third cups. This study is a huge waste of money. The guy says it's astonishing to find the two genes after seaching 300,000 genes. Well, I think he got tired of looking and wanted to finally prove he was justified in looking. Honestly, the difference between 40mg of caffiene is nothing and meaningless. What a waste of time and money. Who authorized such an extensive study (47,000 people?) based on such a poor design? "We're going to ask these people if they drink a lot of caffeine based on a 40 mg difference." Dumb. They need to keep looking if they really think this is the case. It's weak. There are probably a lot of things those genes could be correlated with. I could just as easily have claimed those people are slightly more high strung and it's based in genetics. This study is disappointing and not news. I can't believe it got published.
