Better Health Benefits with Sports Bottles by:Kim Medeiros

Did you know that drinking water from plastic containers and bottles pose a health risk to you

? Many people do not know the risks involved in drinking water straight from plastic bottles and the best part is, some types of plastic are worse than others. When buying bottles, you have to consider the reason of purchase as well as the type of plastic being used. In the bottle industry, manufacturers use different types of plastic material to produce bottles so it is important to recognize the many different types of plastics. Sports bottles normally use high quality and safe plastic and most use aluminum, which is a better and more durable alternative.

In America, plastics are given the rating from one to seven and this number is usually printed on the base of the container, and is inside the symbol of the recycling triangle image. The one to seven rating classifies the "resin identification code" that represents different types of resin. Apart from this, the abbreviations for the type of plastic will also be printed. Examples of these abbreviations are such as PET which is a type one in the plastics range and it stands for polyethylene terephthalate.

Disposable soft drink and sports water bottle made of plastic are rated on whereas milk jugs, shampoo bottles and liquid detergent bottles tend to be made from high density poly ethylene (HDPE), and labeled as number two plastic.

Number three is poly vinyl chloride (PVC) and items such as meat wrap, cooking oil bottles and plumbing pipes use PVC. Number four is low density polyethylene (LDPE) and can be found in cling wraps, grocery bags and sandwich bags. Number five is polypropolene (PP) and is commonly used in cloudy plastic water bottles and yogurt cups. Disposable coffee cups and take out containers use number six is polystyrene (PS) and baby bottles, some reusable water bottles and stain resistant food-storage containers come in number seven which is any sort of plastic that doesn't fit into the first six categories. If a plastic container doesn't have a recycling symbol with a visible number it is considered a number seven.

A study conducted in 1998 on plastics showed that bisphenol-A (BPA), a chemical which mimics the hormone estrogens, can seep into the water from polycarbonate bottles. This study was published in the April 2003 issue of Current Biology. According to the research, BPA has a lot of harmful effects as it has been tested on the reproductive process of rats and mice. Some of the side effects are low sperm counts to changes in tissue that resembles early-stage breast cancer. These test show that similar changes can happen to human beings as a result of PBA. Bottles with number one bottles (PET) should only be used once and after finishing the liquid in them, take it to the recycling center.

For extended use, buy sports bottles and water bottles with number 2,4 and 5 ratings. These types of plastics are your best choices and they do not transmit any known chemicals into your body through the food and drink you consume. Also, these types of plastics are recyclable.
