Water Bottles

17214426_mWater is the most essential nutrient for human health. Among its most important functions, water assists in transporting oxygen and nutrients to cells and exporting waste out of cells.[1] Adequate hydration can help prevent cognitive impairment, kidney stones, bladder cancer, and colorectal cancer. In the case of cancer, it has been theorized that increased water intake and corresponding increased urinary frequency reduces contact of carcinogens with mucous membranes in the digestive system.[2]

There is growing awareness that adults require 8-10 eight-ounce glasses of water per day to maintain a healthy level of hydration.[3] Consequently, many people drink water throughout the day from reusable water bottles. One alternative is to use a reusable plastic, BPA-free bottle, but manufacturers typically do not reveal the ingredients of their “safe” plastic.[4] Consequently, independent scientists cannot verify whether the BPA-free alternative is in fact non-toxic in the short-term. Aluminum bottles should also be avoided since they are frequently coated with an epoxy resin liner that may contain BPA or other dangerous chemicals.[5] The only reliably non-toxic option is stainless steel.
