Pura Kiki Stainless Steel Baby and Sippy Bottles

Bottles that grow with your baby Pura

The Pura alternative to Plastic baby bottles and sippy cups.

The stainless steel Pura baby bottles and sippy cups are a great alternative to plastic.  If you have decided to stay clear of any plastic baby and sippy bottles, and now you are on the hunt for a stainless steel baby bottle that can also be used as a sippy cup, Pura baby bottles are the bottle you have been looking for.

In general, I tend to lead parents to a hybrid style bottle that will grow with their child. In other words, a baby bottle that can then easily also be used as a sippy bottle. For glass, I usually steer parents to the Lifefactory glass bottles (I will write more about Lifefactory soon). And for a stainless steel hybrid bottle, Pura is the way to go.

Pura designed their line of baby and toddler bottles with a few simple concepts in mind featuring:

  • no plastic components
  • a versatile style opening that allows you to choose from a large selection of nipples and sippy spouts that are compatible with the bottle

Why is this so important? Can’t I just buy the Pura brand of nipples?

Yes, you can, but as a lot of parents find out over time, your baby or toddler may tend to prefer a brand of nipple or sippy spouts over another. So instead of having to spend your money and time looking for a perfect fit, Pura makes it easy.

Pura bottles come in either a 5oz. or 11oz baby bottle size or an 11oz. sippy size. There are even some fun sealing disks that can turn the bottle into a great storage container for snacks while on the go. Below is a chart of all of the nipple and sippy tops that are compatible with the Pura bottles.

Minnesota Bans BPA in Baby Bottles & Sippy Cups

BPA ban in Baby bottles and Sippy Cups

Minnesota has become the first state to legislate a ban on Bisphenol-A (BPA) in baby bottles and sippy cups.

Interestingly, but not surprisingly, the FDA continues to maintain the chemical is safe.

Other states (California, Connecticut) are set to follow suit and this precedent by Minnesota will only serve to make further bans more likely. Canada has already banned BPA from numerous baby and toddler products.

Unfortunately, even in Minnesota, you’ll still have to wait until 2010 before the ban goes into effect.

While we applaud these efforts we must point out that most (all?) proposed bans target only a very small range of products used by infants and the youngest of children. Important product categories such as feeding and food storage containers, amongst others, are still not being addressed, not to mention the continuing risk of BPA in older children.

Nanotechnology & You

Nantotechnology and you, learn more about Nanotechnology

There is no firmly established definition of nanotechnology but this extremely diverse field could simply be described as the science of the extraordinarily small. A human hair is 80,000 nanometers wide and nanomaterials are commonly accepted to reside in the 100 nanometer or smaller range. In short, nanotechnology operates at the atomic and molecular levels.

Nanotechnology is a very promising field and it seems almost certain that humankind will benefit, perhaps greatly, from further study. Equally certain is that some applications of nanotechnology will prove to be dangerous to human and environmental health. Unfortunately, as with commercially produced chemicals, we are once again putting the cart before the horse in a big way. The following lists just a few consumer products already utilizing nanomaterials:

  • Food (nanofood) & food packaging products
  • Many agricultural products
  • Kitchenwares
  • Clothing
  • Sunscreen
  • Makeup
  • Household appliances

In order to keep a huge topic manageable, the rest of this post will concentrate on the food, food packaging and agricultural applications of nanotechnology.

Nanotech In Our Food Supply, Really?

As frequently occurs with any new and exciting technology a debate is brewing between the keep-government-regulation-out–of–my-hair-so-as-not-to-stifle-innovation crowd and the let’s-make-sure-this-stuff-is-safe-before-releasing-it-on-unsuspecting-consumers crowd. As of this writing, the “innovators” and big business are winning.

If you don’t believe that consider the current state of affairs in the US:

  • No nanotech-specific regulation or safety testing is required before nanomaterials can be used in food, food packaging or agricultural consumer products.
  • There are no labeling laws relating to nano ingredients that are in our food supply or its packaging.

In essence, the public’s right to make up their own minds regarding the consumption of nanofoods and materials is being usurped in much the same fashion as with genetically modified foods. This is, in the classic sense of the word, an outrage.

I’m no Luditte. I’m all for innovation. I support clean energy, stem cell and, yes, nanotech research. But it is equally outrageous that we would not regulate a potentially dangerous new technology in any way, shape or form before unleashing it on the public. It is the height of recklessness and clearly a sop to the usual monied interests.

Furthermore it is a false choice between requiring safety research and encouraging innovation. Research does not stifle innovation, it creates it! It is research that will show us the way forward as well as the paths to avoid. This is a far superior approach to creating instant profits by using the public as a beta tester.

Make no mistake, the pressure from industry to use and develop nanotechnology will be enormous, and I’m actually fine with that. But if I’m any sort of observer of such things, they won’t want to be regulated – at all. And therein lies the problem.

Two last points:

  • Enormous amounts of money are going to be made in the field of nanotechnology in the decades ahead.
  • On the smaller half of the nanotech scale, 50 nanometers and smaller, the laws of the universe as we know them give way to the bizarre and largely mysterious laws of quantum physics.

Did I mention I favor regulation of nanotechnology?
