PLASTIC PACKAGING CAUSE FOR OBESITY AND DIABETES?

It is unimaginable as to why hundreds of chemicals are allowed for use by the food industry for one reason or the other. While pharmaceutical industry is shackled, forcing it to be more careful and cautious in using different ingredients in medicine formulations, food industry is allowed to get away, mostly under the so called GRAS provision under which proof of safety is not insisted on!  The result is that many of the food ingredients had to be withdrawn after consumers were exposed to their dangers unnecessarily. Latest to join the list of monster chemicals are phthalates and Bisphenol A. Though indications about their suspect safety credentials were known earlier, they were allowed to be used for technical reasons ignoring the harm they could bring upon the consumers. The dangers posed by the above chemicals have been highlighted succinctly in a recent report which has some credibility. 

"Children exposed to two chemicals commonly used in food packaging are more likely to be obese or show signs of diabetes precursors than those with lower exposure, new research suggests. Researchers found urine levels of one type of phthalate, used to soften plastic, were tied to a higher risk of insulin resistance among teenagers. Based on data from the same large nutrition survey, another study group linked bisphenol A, or BPA - used to line aluminum cans - to obesity and larger waists in youth. According to the Centers for Disease Control and Prevention, about one in six U.S. children and teenagers is now obese. "Clearly unhealthy diet and lack of physical activity are the drivers of this epidemic … but increasingly environmental chemicals are being identified as possible contributors," Dr. Leonardo Trasande, a pediatrician from New York University, said. He and his colleagues analyzed data from a nationally-representative health and nutrition survey conducted in 2003 to 2008, which included urine and blood tests for 766 adolescents aged 12 to 19. They found urinary levels of one particular type of phthalate, known as Di-2-ethylhexylphthalate (DEHP), were closely tied to a teenager's chance of having insulin resistance, a precursor to diabetes. Just under 15 percent of study participants with the lowest one-third of DEHP levels were insulin resistant, compared to almost 22 percent of those with the highest levels. DEHP, Trasande said, is often used to soften plastic bottles. It's used in plastic that is printed with the number 3 for recycling. The researchers said their findings don't prove that eating food packaged with phthalates causes insulin resistance. For example, it's possible children who are already insulin-resistant have unhealthier eating habits and eat and drink more packaged products - thus the higher phthalate levels in their urine. But Trasande told Reuters Health the chemical may influence how the body secretes insulin in response to sugar. Because of that, he tells parents to avoid buying plastics made with DEHP. "I advise them not to wash plastic containers in the dishwasher," he said. And, "When the plastic is clearly etched or damaged, it's time to throw it away." For a separate study published concurrently in Pediatrics, Dr. Joyce Lee from the University of Michigan in Ann Arbor and her colleagues used nutrition survey data through 2010 to compare BPA levels in the urine of six- to 18-year-olds with other health measures. In their analysis of 3,370 kids, BPA - an industrial chemical that may mimic estrogen in the body - was not linked to insulin resistance or blood sugar. But children with higher BPA levels were more likely to be obese, and tended to have a higher waist circumference-to-height ratio, than those with the lowest levels."

The particular variety of Phthalate-DEHP is implicated in developing insulin resistance leading to diabetic conditions, especially among children. Similarly BPA is now being confirmed as an obesogenic chemical causing early obesity among children. On the face of the fact that almost 20% of American kids are obese and the consumption of processed foods is very high in that country, there is a definite cause for alarm. It is high time that safety authorities wake up to this shocking reality and revisit the issue of safety of all food ingredient currently allowed for use by the industry before further damage is caused to the innocent public.
