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 can be toxic, and water-containing levels over 1.0 mg/L should not be used for drinking. If there are iron pipes present, the water can be colored rust or reddish, and contains metallic or sulfur odors, and sediment.Eventually corrosion can cause the piping to fail, in some cases in less than 10 years.
