What kind of “natural trace minerals” are left in filtered water?
The best water filters do not take everything out of the water. Some minerals are needed by your body in order to stay healthy, and water can be a great way to get some of these healthy minerals. The best water filters are designed to take out unhealthy chemicals and leave in the necessary minerals at natural and healthy levels.
Calcium is one of these minerals. As most people know, calcium is necessary for healthy teeth and bones. A lack of calcium causes bones to become brittle and break more easily. The World Health Organization recommends that drinking water should have at least 60 milligrams per liter, as calcium-poor water also increases the risk for coronary diseases.
Iron is also a mineral naturally found in good drinking water. In small doses, iron helps your body to create hemoglobin, which allows your body to take the oxygen from your lungs and give it to your muscles, which then use that oxygen to help you move. Too much or too little iron can make you unhealthy, and a water filter is a great way to make sure that your water contains the correct amount of iron.
Some people may be surprised to realize that copper, in small amounts, is very good for your body. It helps to remove contaminants from your body, can reduce the risk of cancer, and can help to relieve pain caused by arthritis.
Finally, Aquasana water filters leave magnesium in the water. Magnesium helps to prevent overactive nerves in muscles. A lack of magnesium will lead to an increased risk for muscle soreness, spasms, cramps, and fatigue. Another function of magnesium is to aid your body in turning carbohydrates and fats into energy the body can use. Without magnesium, your body must work harder to turn your food into energy.
Distillers and reverse osmosis type water systems strip all the natural minerals from water leaving it in an acid state and very aggressive.
