Today, BPA is used in plastic containers, other food-packagings, electronic items and many other things.
Studies published in (2007–2016,) National Center for Biotechnology Information, U.S National Library of Medicine and Evidence for bisphenol A-induced female infertility: American Society for Reproductive Medicine have linked BPA to causing infertility, obesity (BPA has been shown to affect lipid metabolism and promote weight gain in animal studies), birth defects in babies, heart disease and Type 2 diabetes, and many other health problems such as polycystic ovary syndrome (PCOS), premature delivery, asthma, and liver/immune/thyroid dysfunction.
Unfortunately, the rush to replace BPA with the newer Bisphenol “S” (“BPS”) has proven premature. Both BPA and BPS will leach into the liquids or foods they protect. We are only now learning that BPS is just as toxic as its predecessor and may cause cancer in breast cells. But why would you be surprised, when its chemical composition is structurally similar to BPA?
According to the Mayo Clinic, Exposure to BPA is a concern because of possible health effects of BPA on the brain and prostate gland of fetuses, infants and children. Additional research suggests a possible link between BPA and increased blood pressure.
Polyethylene terephthalate, or PET, is the most commonly used material in single-use plastic food and water bottles. Strong and adaptable, it can be molded into almost any shape, and thus its practical popularity in the food and drink industry. In optimal conditions, PET keeps its contents safe, but in the tropical climes of Malaysia, where heat, humidity and sunlight are a fact of life, PET containers begin to lose their integrity and break down into harmful, microscopic parts.
You may be thinking, But the bottle is on a supermarket shelf. When is it going to see light? Well, it could have been sitting in the light of the full sun at any time between delivery from warehouse/factory to the store. Between loading and unloading, and movement of the product from point to point in the supply chain. After purchase, it may sit in your car for some time... But UV light isn’t the only consideration. Humidity and heat are also factors in the plastic components breaking down.
With opaque Watertree pods, the paper outer protective covering ensures that absolutely no UV light enters the packaging. This effectively eliminates the threat of UV light degrading the material. Its internal lining means also that it is not exposed to variations in humidity (only to the liquid or food it contains), removing the second threat.
RO (Reverse Osmosis) water is the purest, most neutral option.
RO water does not contain any sodium, making it perfect if you are on on a limited sodium intake.
The process combines carbon filtration with a special membrane that removes sodium and the tiny particles not caught by the filter. This system is very efficient at removing impurities, and these could include minerals. But you should not be depending on your water intake for your mineral requirements, a better source of minerals is nuts, seeds and a varied diet.
RO also removes lead, reducing the risk of kidney / liver issues.
A study published in JAMA Pediatrics found that mothers who had consumed fluoridated tap water while they were pregnant tended to give birth to children who ended up having slightly lower IQ scores by ages 3 to 4.
RO water is flouride-free.
