Bottled water may contain fluoride. Consumers drink it as a convenient way to hydrate. Although some brands of bottled water contain fluoride, the amount of fluoride is typically not sufficient enough to prevent tooth decay or promote oral health.
The fluoride content in some bottled water occurs naturally in source water or it can be added. The US Food and Drug Administration established limits for how much it can be in a plastic bottle water. The limit is based on the source of the water and other factors. If the water is identified as demineralized or distilled, it has been treated in a way that it no longer contains fluoride or it may only include a trace amount of this mineral. Because of this, the fluoride in bottled water is not harmful.
However, the FDA does not require manufacturers bottled water to list the amount of fluoride on the label. The manufacturer will list the amount of this mineral on the tag if it has added it to its product within the set limits.
For years, many experts argued about how safe it is to drink water with fluoride. Is it toxic to humans? Several studies showed that it is harmful if the level is extremely high, which causes neurotoxicity in adults. It can also negatively affect memory and learning. Other studies also found strong indications that it can influence the cognitive development in children.
The problem with bottled water is not the fluoride content but its components and how it is made. A plastic water bottle contains bisphenol A, a chemical used to stabilize plastics or hard plastics. It can be used to prevent cracking in softer plastics. This chemical can contribute to a high level of estrogen in your body that may cause ovarian, prostate, and breast malignant tumors.
PET bottles can also be used to store drinking water. They may be free of BPA, but they can still pose health risks as they contain fecal matter, saliva, and food residues. When they are re-used, they can be hazardous to your health.
In addition to BPA and PET, another chemical used to make a plastic bottle is phthalate. This chemical can cause liver cancer, sterility in males and other human diseases.
Bottled water products do not only affect human health, but they can also negatively impact the environment. Bear in mind that millions of water bottles are thrown away each day, causing a huge amount of waste.
Drinking bottled water containing fluoride does not help you avoid tooth decay. The fluoride content is not harmful, but the bottle itself is not 100% safe for your body and the bottles are not safe for the environment.
