When choosing a safe water bottle the most important factor to consider is the material it is made of. Small amounts of the materials you eat or drink out of eventually end up in your body. Common materials that water bottles are made of include plastics, metals, and glass. Each of these materials has advantages and disadvantages when making a safe water bottle. Plastic Most water bottles are made of plastic. Plastic is a petroleum-based resin that is popular with water bottle manufacturers because it is easily molded or extruded. Most of today’s water... 

There is much debate on the internet about the safety of SIGG water bottles. Much of the debate arises from the fact that there has been little to no research on their safety compared to stainless steel and plastic water bottles. In this article I will go over the limited information available (and why it is limited) and ultimately try to answer the question: are SIGG water bottles safe? What we know for sure about SIGG water bottles is that the exterior is made of aluminum while the interior is lined with a “water based epoxy resin.” The liner is added... 

Stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content. The name comes from the fact that stainless steel does not stain, corrode or rust as easily as ordinary steel. 300 series stainless steels (of which water bottles are made) comprise over 70% of total stainless steel production. They contain a maximum of 0.15% carbon, a minimum of 16% chromium and sufficient nickel and/or manganese to retain an austenitic structure at all temperatures from the cryogenic region to the melting point of the alloy. A typical composition of 18%... 

Stainless steel water bottles are cleaned easily with baking soda or distilled vinegar. A new water bottle should be soaked in water and vinegar overnight. This will get rid of the metallic taste that can be a source of complaint. Water bottles can also be cleaned by putting some rice with vinegar and shaking well.  Read More →

Most are made of 18/8 food-grade stainless steel (Guyot Designs uses 18/10 surgical grade stainless steel). They are made in China. Most companies claim that their bottles are made “responsibly” in China. Since most stainless steel water bottles are not insulated, they are not good for hot liquids (This can be overcome by using an insulating tote). Freezing is not recommended Drinking out of stainless steel may seem quite different at first, but accustoming oneself to this material does not take long. Stainless steel doesn’t insulate very well and will...

In 2006, a research study described something quite extraordinary. A third of male fish in English rivers were in the process of changing sex, from male to female. Such reproductive anomalies are not just limited to fish. In humans, studies show that girls are hitting puberty earlier than ever, and that male infertility is on the rise. Men now have a greater range of reproductive abnormalities, from undescended testes to mutated sperm. In one study, it was found that sperm counts have dropped by 30% in the last fifteen years. The incidence of breast cancer...
