When you have symptoms (belly pain, diarrhea, a lot of gas), choose foods that are easy on your gut. The trick to managing the disease is to choose foods from the left hand column when you have a flare up or an upset in the functioning of your gut. These foods are low in fiber, fats and are easier on you.
Copper pipes corrode as well, but (theoretically) over a longer period than the galvanized types. Generally a copper pipe can last 50-70 years under good conditions. PH levels in the water and grounding both affect the pipes and speed up corrosion extensively.
Copper typically takes longer and/or more workers to install than PEX or CPVC pipes. For example, Repipe1 in California typically schedules one day for any re-plumbing project, but uses a three-member crew to install PEX and a five-member or larger crew for copper pipes.
