Bought a standard poodle puppy.  Bringing him home October 5, so October will be full of housebreaking, and FUN.

Uh-Oh. Animals Are Getting Fat Too

A new research study shows that America’s obesity problem is not limited to humans.  Rather, our animals are getting fatter too.  Cats and dogs, research animals including primates and mice, and wild urban rats are all undergoing an increase in obesity.

         This new finding goes along with the puzzling nature of the human obesity epidemic.  Lots of magazine articles blame American obesity on super-sized MacDonald’s meals and sitting all day in front of computers and electronic games. 

         But lots of studies show that the obesity problem is not that simple.  Other factors seem to be at work.  Now, the fact that animals living near or with humans are also suffering from rising obesity points to some common environmental factor.  The study I am citing controlled animal diets and exercise, so the animals are not getting fat from being snack-happy couch potatoes

         In my last post (Dec. 28, 2010), I wrote about the possibility that the plastic ingredient BPA, an endocrine disruptor, could be causing declines in sperm counts.  This same BPA has been shown to have a significant connection with obesity, as have other pollutants.  Certain cold viruses have also been shown to be connected with obesity.

         So it seems quite possible that our environment is working right along with our lifestyles to make us and our animals fat.  When this mystery gets solved, I wonder if we’ll also understand the environmental factors that bring about autism, breast cancer, and other modern scourges.

         With all that still remains to be discovered, 2011 should be a year full of wonder.  Happy New Year!

BPA and Low Sperm Count

There’s more and more news about hazards of Bisphenol A or BPA.  Some of the most recent comes from Kaiser-Permanente, indicating that even small amounts of BPA exposure can lower sperm counts and sperm motility in men. 

         To me this qualifies as a wonder, though a negative one.  BPA apparently mimics certain hormones and disrupts processes controlled by those hormones.   We don’t yet know exactly how this comes about, but eventually researchers will figure at least some of it out.  And it will illustrate one or more wonders about the way our cells function when they are free of poisons.

         I looked up the video in this post so that I can show it to you here, and so that I can refer back to it next time.  In my next post, I’ll write about an obesity mystery that might be related to BPA also.
