How Bad are Plastic Water Bottles for Your Health, Really?


In 2008, Americans drank nearly 9 billion gallons of bottled water, which is second only to soft drinks as the largest beverage type in the U.S. market, according to the Beverage Marketing Corporation.
In the first study of its kind, researchers determined just how much BPA you absorb when you drink bottled water.
Its popularity has been growing strong since 2000, with significant sales growth noted every year of the decade … that is until now. In 2008, the gallons of bottled water consumption went down by 1 percent, for the first time this decade. And whereas in 2007 Americans drank 29 gallons of bottled water each, in 2008 that went down to 28.5 gallons. It’s a small decrease, but perhaps a sign of larger changes to come.
What are You Really Drinking When You Drink Bottled Water?
Plastic water bottles have come under scrutiny in recent years for both their environmental and health effects, including those surrounding the chemical bisphenol-A (BPA).
That BPA can leach out of plastic during everyday use, causing health problems, is hardly news. It’s now widely known that BPA mimics the female hormone estrogen and may affect fertility and promote cancer. And just last year it came out that BPA may also lead to heart disease, diabetes and liver problems.
Studies have shown that detectable levels of BPA exist in more than 90 percent of the U.S. population, but exposure has been blamed on not only drinking water and food, but also on dental sealants, dermal exposure and inhalation of household dusts.
Which leads one to wonder, just how much BPA are we exposed to when drinking from a plastic bottle? And how great are the health risks, really?
Well, a new study from the Harvard School of Public Health (HSPH) found out.
The researchers recruited Harvard College students for the study in April 2008, and all 77 participants then began a seven-day “washout” during which they drank all cold beverages from stainless steel bottles in order to minimize BPA exposure. For the next week, participants were given two polycarbonate bottles and asked to drink all cold beverages from them.
Urine samples were taken at the end of each week-long period, and the results that came back were shocking: levels of BPA rose 69 percent after just one week of drinking out of plastic bottles.
"We found that drinking cold liquids from polycarbonate bottles for just one week increased urinary BPA levels by more than two-thirds. If you heat those bottles, as is the case with baby bottles, we would expect the levels to be considerably higher. This would be of concern since infants may be particularly susceptible to BPA's endocrine-disrupting potential," said Karin B. Michels, associate professor of epidemiology at HSPH and Harvard Medical School and senior author of the study.
While previous studies have found that BPA could leach from polycarbonate bottles into their contents, this study is the first to show the corresponding increase in BPA levels in humans.

The end result is this: if you drink out of plastic water bottles, you can pretty much guarantee that you’re increasing your levels of BPA, which is very risky for your health.
Why You Do NOT Want to Drink Out of BPA-Containing Plastic Bottles
Chronic exposure to very low levels of BPA, such as might occur when drinking bottled water, is potentially very harmful.
"An expert panel of scientists has concluded that exposure to extremely low doses of bisphenol A is strongly linked to diseases such as breast cancer, prostate cancer, and diabetes, and to reproductive and neurological development," the Sierra Club reported.
And single-serve bottles are not the only ones to be concerned about. Consumer Reports found in 2000 that eight of 10 5-gallon water jugs they tested contained residues of BPA.
While the use of BPA in polycarbonate baby bottles was banned in Canada in 2008, and some manufacturers have voluntarily eliminated the chemical from their bottles, this is not yet widespread in the United States.
In fact, BPA is so widely used that it may be nearly impossible to avoid exposure entirely, however you can greatly reduce your exposure by avoiding BPA-containing products as much as possible, including one of the biggest BPA predators: plastic water bottles.
Plastic containing BPA may be called:
Polycarbonate
Lexan
Polysulfone
Make sure any plastic bottle you give to your baby is BPA-free.
Though it is generally clear, it can be tinted in various colors. Plastic that contains BPA carries the #7 recycling symbol, as well, so never use those bottles.
Are There Any Safe Alternatives?
Drinking plenty of pure water throughout the day is one of the best habits you can get into for your health. This is also what makes bottled water so convenient; simply throw a bottle in your purse, briefcase or gym bag and it’s easy to quench your thirst anytime.

Ban Plastic Bottles


Bottled water is typically considered to be a healthy alternative to drinking plain tap water. In fact, Americans drink approximately eight million gallons of bottled water every year. While bottled water is definitely a better choice than soft drinks or sports drinks that contain high fructose corn syrup, bottled water is not a good choice for the wellbeing of the earth. Here are some of the health and environmental issues associated with consuming bottled water.1.It takes three to five times more water to manufacture the plastic water bottle than actually is contained in the water bottle itself. Because each bottle should only be used one time (so as not to contaminate water with phthalates) this seems to be an inordinate amount of water utilized in the manufacturing process.2.Plastic is a petroleum product so using plastic water bottles depletes this non-renewable resource. The Pacific Institute has calculated that the manufacturing process for making plastic water bottles used in the US consumes roughly 17 million barrels of oil every year.3.Plastic water bottles are not recycled the way they should be. It is estimated that in 2005 only about 12% of plastic water bottles were recycled. This is partly because water bottles are many times not included in local recycling plans. Another factor is that bottled water is often consumed away from home and so is disposed of in mixed-trash containers instead of being recycled. In a 2002 study by Scenic Hudson it was reported that 18 percent by volume of recovered litter from the Hudson River was beverage containers. In landfills, water bottles will remain biodegrading for approximately 1,000 years. Incinerating used water bottles produces toxic byproducts including chlorine gas and ash that contains heavy metals.4.Roughly 94 % of the bottled water in the U.S. is bottled domestically. Of this percentage, approximately 25 percent sold is just reprocessed municipal water according to a 1999 study by the National Resources Defense Council.5.Using plastic bottles that contain Bisphenol A is detrimental to human health. Bisphenol A behaves similarly to estrogen. This means that when enough of this accumulates in the body there will be negative health effects. Bisphenol A has been linked to obesity, diabetes, breast cancer, and hyperactivity.Alternatives to Plastic Bottles: Stainless steel, glass, and aluminum water bottles are safer and more earth-friendly. There are also many companies manufacturing BPA-free and phthalate-free plastic water bottles.Whatever kind of plastic is used, it is important to hand wash any plastic food and beverage items in warm (not hot) water. Washing plastic items at the high and sustained temperatures of an automatic dishwasher is detrimental to human health and should be avoided at all costs.Source: http://www.recordonline.com/apps/pbcs.dll/article?AID=/20071014/NEWS/710140325/-1/NEWShttp://www.pacinst.org/

Tap Vs. Bottled Water?


Tap vs. Bottled-What Should You Drink?
Glug, glug, glug!
Glug, glug, glug-- as we sip bottled water in our cars, at the gym or behind our desks.The sound you DON'T hear is the thwack of 60 million bottles a day being tossed into U.S. landfills, where they can take up to 1,000 years to biodegrade.If that's not enough to turn your conscience a brighter shade of green, add this: Producing those bottles burns through 1.5 million barrels of crude oil annually--enough fuel to keep 100,000 cars running for a year.Recycling helps but reusing is even better. Invest in a couple of portable, dishwasher safe, stainless steel bottles that won't leach nasty chemicals into your water. (Avoid refilling the water bottle you just emptied; the polyethylene terephthalate it's made of breaks down over time.)3 Reasons to Turn on the Tap1. Tap water is tested dailyUnder the Safe Drinking Water Act, water suppliers are required to provide an annual report on the quality of your local water and to test tap water daily. By comparison, the FDA examines bottled water only weekly, and consumers can't get the agency's results.2. Tap water is a bargainBottled water costs about 500 times more than tap. If you're into really fancy labels, up to 1,000 times more.3. Tap water is often tastySome places (New York City for one) have delicious water, but if you don't love the flavor of yours, the solution is simple: Run your tap water through a Brita or Pur filter to remove most tastes and odors.The average home filter goes for $8.99 and produces the equivalent of 300 large (16.9 ounce) bottles of water. That's about $0.03 cents a bottle, versus the $1.25 or so you'd pay in a market.One last thing: Don't just think about making this switch; actually do it. Today. It does the world and you a lot of good. Plus, allowing nagging, unfinished tasks (known as NUTs) to go undone can make you years older!

Are You Drinking Enough Water?

Keeping hydrated is very important - especially in the summer months. Each day you should drink half of your body weight in ounces of water. (for example - 140 lbs. means you drink 70 oz. of water daily. Make it cool water to experience a temporary boost in your metabolism. Drinking cold water rather than room temperature makes your body work harder to warm it - hence the boost in metabolism.

Water Bottle Warning

Think twice before drinking hot liquids from plastic bottles. New research from the University of Cincinnati shown that bottles made of polycarbonate plastic can release a certain endocrine-disrupting chemical up to 55 times faster when exposed to hot water. A synthetic chemical also found in baby bottles, bisphenol A (BPA) is known to mimic female hormones and alter endocrine function. Although there's limited research on BPA's human-health effects, a number of animal studies have concluded that the chemical may interfere with reproduction and hamper brain development.

Even when they're not filled with hot liquid, polycarbonate bottles can leak BPA. But occasionally drinking cold water from plastic isn't likely to drastically increase your exposure, says Kirby Donnelly, Ph.D., head of Texas A&M University's Environmental and Occupational Health department. Still, he notes, opting for glass or stainless-steel bottles is the best way to avoid BPA and other potentially harmful synthetic chemicals.
