It is always interesting to hear from people what their experiences are with black or white coffee. I find this sort of feedback more relevant. White coffees are easier on the stomach, and some people find black coffee too acidic. Everyone is different, and so are their tolerances. I enjoy both, but try to keep the volume of milk as low as possible. First thing in the morning, a white coffee is more palatable, as I find an espresso quite harsh on an empty stomach. I do enjoy black coffees through the day, and am always partial to an iced latte or deviation of it on a hot day. When dining out, I shy away from white coffees as generally the milk used in cafes, does not always agree with me. As to health benefits of certain foods, I listen to my body. Fads come and go, and research depends on the parameters, which should be carefully analyzed. Data can be manipulated to show whatever it is you seek to promote.....
