Ok, last week’s title: “Plastic makes you fat!” obviously was partly provocation, like a cheap news paper screaming shameless stirring headlines to get more sales. Sorry! But I was so surprised finding out about the link between plastic and weight gain, I had to share it.
But than, I started thinking, do I see a link between plastic and fat people? Like, are my friends who drink out of reusable (polycarbonate) plastic drink bottles and eat canned food notably bigger? I thought it would be too awkward to analyze, to make a table and list down all my friend’s names in the first column, second column “drinks from bpa bottles yes/no”, third column “fat yes/no?”. So I didn’t.
My statement about last week is not necessary about plastic. It is about a component that makes plastic hard and clear. It’s about BPA: that is the bad guy. According to North Carolina State University (NCSU), it enters our world in large numbers: 6 billion pounds of BPA is produced each year to be included in items from beverage containers to eyeglass frames to epoxy linings inside cans and jars.
Babies have been brought up by milk in bottles since decades. Bad news: the classic baby bottles contain BPA. And according to research by Dr. Heather Patisaul, an assistant professor in the Department of Biology at NCSU, especially in our early years, BPA is brutal to our bodies.
This lady studied the endocrine-disruptive properties of soy products and received two grants totaling $174,000 to examine the changes that occur in the brains of rats exposed to BPA. She found that especially critical during early development, BPA interferes with the system of the body. But many of the animal studies done by for example Betts, find that BPA exposure leads to a higher body weight do not find that increase in body weight until the exposed animals reach puberty. So a short cut conclusion: drinking out of a plastic BPA-containing bottle as a baby, increases the risk for obesity on a higher age.
