Coffee or no Coffee

Coffee or no Coffee
Coffee is a brewed beverage with a dark, slightly acidic flavor prepared from the roasted seeds of the coffee plant, colloquially called coffee beans. The beans are found in coffee cherries, which grow on trees cultivated in over 70 countries, primarily in equatorial Latin America, Southeast Asia, South Asia and Africa. Green (unroasted) coffee is one of the most traded agricultural commodities in the world.[1] Coffee can have a stimulating effect on humans due to itscaffeine content. It is one of the most-consumed beverages in the world.

I believe that a lot of people fall in love with coffee, and I am one of them. However, coffee is hard on kidney when you already have Renal Failure. Some patients with Renal Failure strictly follow it. And some people may oppose to it. This is an old argument. Why do I say coffee is bad for patients with Renal Failure? There are three reasons as follow.
Ⅰ Coffee contains much caffeine, which is common sense. Many patients with Renal Failure maintain that caffeine has not bad effect on kidney disease, but we should not forget that coffee can always let spirit rouse, and then difficultly in falling asleep. Low quality of sleep and body can not get well rest, which may arouse the relapse of kidney disease.
Ⅱ Coffee restrains the absorption of ferrum, which is reported by dietitian. Patients with Renal Failure may know there will be renal anemia when Chronic Kidney Disease (CKD) develops into stage 3. At this moment, coffee plays a role in stopping the absorption of ferrum, which is bad for treating renal anemia
