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.
Pipe longevity also depends on the thickness of zinc in the original galvanization, which ranges on a scale from G40 to G210, and whether the pipe was galvanized on both the inside and outside, or just the outside.
