Check out the nutrition label on a bottle of water, most likely you will find more ingredients than good old H20. Bottled water companies are purifying water and then adding ingredients that impact the taste. According to Marion Nestle, professor of Nutrition, Food Studies, and Public Health at NYU, most people find distilled water to taste flat and prefer chemically enhanced sweet water.

Many popular plastic water bottle brands will add calcium, magnesium and a little salt to sweeten the taste of the water. For example, Dasani lists magnesium sulfate, potassium chloride, and salt alongside purified water on the label and Nestle Pure Life’s nutrition label includes calcium chloride, sodium bicarbonate, and magnesium sulfate.  Although these salts are generally naturally occurring chemicals, consumers should still take pause. The EPA recommends only drinking water that contains 20 mg of sodium or less and often the typical amount of sodium in bottled water averages to be about 17 mg per liter.

Nestle recommends that consumers stick to drinking tap water. “To the extent that tap water is clean and free of harmful contaminants,” says Nestle, “it beats everything in taste and cost.” Follow Marion Nestle’s advice and switch to a Quench Bottleless Water Cooler to have a miniature water purification plant in the office, so you have the cleanest, best-tasting water delivered to your glass!
