For people who are not used to drinking hard water, it is easy to have symptoms such as gastrointestinal dysfunction, abdominal distension and excessive exhaust, which will increase the burden on the stomach.
If vegetables, fish, meat, bean products and other foods are cooked with hard water, it is easy to cause protein precipitation and inorganic salt precipitation, which makes cooking difficult, reduces the nutritional value of food and affects the taste. Soaking tea and coffee in hard water will also greatly reduce the taste of tea and coffee.
