I have a serious coffee habit. After not drinking if for years (read two pregnancies in two years), I came back to the habit easily. The seriousness of my habit is not related to quantity, but rather constancy. I begin every day with a homemade latte. I wax and wane on having a second cup, but new research indicates that regular coffee drinkers, who drink two or more cups a day, have a lower all-cause mortality rate than non-coffee drinkers. This is probably due to the abundance of disease-fighting antioxidants in this rich brew. This news makes it so easy to rationalize a second cup.
Unfortunately, the brewing process can change how your java affects your health. Coffee that is not filtered, for example, can can raise blood fats, which means paper filters are better for your health than using a French press.
Bearing all this in mind, I am curious . . .
