Bottled water has an expiration date: why it matters
Each of us always has several bottles of water. And now, during the quarantine on COVID-19, many people stock up on large packages of bottled water to make sure that they have enough for a long time. But it turns out that the water in the bottles really can not be stored forever, because it has an expiration date. Writes about this Reader's Digest.
When was the last time you checked the expiration date of bottled water? Yes, she has an expiration date. And although the reason meat or dairy products have an expiration date is pretty obvious, you may be surprised that bottled water also has a date stamp.
It turns out that you need not worry about the quality of the water, but about the plastic in which the water is packaged. Manufacturers typically use polyethylene terephthalate (PET) for small bottles and high density polyethylene (HDPE) for coolers.
According to Amy Lee Mercy, a healthy lifestyle expert and best-selling author, these plastics "leach out into the liquid, especially when the bottle has been exposed to heat, including sunlight." The toxicity contained in the plastic material penetrates the water. In addition, you will be surprised at how often you should wash a water bottle for reusable use.
This not only affects the taste of water, but can also pose a serious health hazard. Substances emitted by plastic disrupt the endocrine system, cause diseases of the reproductive system, various types of cancer, neurological problems and damage the immune system. Plastic can also cause odors and other unpleasant impurities to accumulate in water.
So how does the shelf life on water bottles protect us from all this?
“Many bottled water companies put a standard shelf life of two years on them,” says Mercy, but admits that this is a fairly arbitrary number. There is no scientific way to accurately predict when the water in the bottle is no longer suitable for drinking, but "it goes without saying that the longer the bottle was in use, the more likely it was to heat up or start to deteriorate."
According to the expert, water quality may depend on several factors.
“Even a completely new plastic bottle, which spent hours or more in a hot machine, can release harmful and toxic compounds into the water. And this can happen even with the first delivery of water to the grocery store, ”says Mercy.
But, as a rule, drinking bottled water is safe for your health if you drink it soon after purchase, do not expose the bottle to prolonged exposure to high temperature, do not keep it too close to household chemicals, and store it in the refrigerator after opening.
