Saudi coffee has less caffeine than black coffee. It contains brown -not black- slightly roasted coffee beans. So when I want less caffeine I drink Saudi coffee. One can drink it like drinking a lot of water, in spite of that, there is no heartburn at all. Regarding that, what is it called when you are full of water? = Perhaps overhydrated? By the way, what is the food called when it has little fat like bread and cheese and jam and so on, in slang? Fat free, although cheese has fat./A low cholesterol diet./Healthy.
