There is a debate you may encounter if you research mineral availability and absorption that is more or less related to the distilled water debate. Organic vs. inorganic nutrients. Like distilled water, you will encounter passionate statements that only organic minerals can be absorbed, for example " Only plants can transform inorganic minerals into organic minerals. "Animals must eat plants or plant-eating animals to obtain their organic minerals. "Inorganic minerals are useless and injurious to the animal organism...Like mineral supplements, mineral waters cannot provide any beneficial minerals to the body. reference "
Bacteria can begin to live or collect in rusty water. When this occurs, water must be treated because coliform bacteria can be present. Iron pipes in older homes, age on the inside of the pipe rather than the outside. Rust and mineral deposits begin to build, oxidize and can flake off. This can cause corrosion, cracks and breaks in pipes, which then will cause leaks in the home. If the home floods, water damage leads to a risk of mold which then becomes a health risk. If mold in pipes or sinks gets into drinking water, it will make the person sick.
As you drink, the alcohol passes into your bloodstream. Ethanol is the intoxicating part of alcohol and its molecules are so small that they can actually pass into the gaps between brain cells. Here they can interfere with the neurotransmitters (the brain's central post office) that govern all the brain's activities. If you drink faster than one standard drink an hour, alcohol will start to flood the brain. Depending on how much and how fast you're drinking, it can affect the brain stem (even cause it to shut down) and this can interfere with vital body functions. A young person, or somebody unused to drink, may experience this after just a few standard drinks taken in one go. Fortunately, alcohol gives warning signs at each level of penetration into the brain so, if you spot the signs, moderate your drinking, or stop altogether.
