Thursday, July 25, 2019 (HealthDay News)-Manufacturers are phased out plastic chemicals Bisphenol A For evidence, it can be harmful to human health. Now, new research raises questions about the chemicals that have replaced it.
Bisphenol A, Or BPA has been used for a long time plastic.. In the past, it was used in a variety of products such as food can linings, food storage containers, water bottles, and even coatings on cash receipts.
However, in recent years, companies have turned to alternatives and advertised their products as “BPA-free.”
It is based on a series of studies showing that BPA is an endocrine disruptor that can interfere with the body’s hormones and have a negative impact on health.Studies show higher BPA exposure obesity, Type 2 diabetes And attention deficit /Hyperactivity For example, a failure.
But is BPA a safer alternative?
“Not much is known about them,” said Melanie Jacobson, a research scientist at NYU Langone Health in New York City, who led the new research. “There was more research on BPA.”
However, she pointed out that alternative chemicals are structurally similar to BPA. This is as the names suggest, such as bisphenol S and bisphenol F, two of the most common BPA alternatives.
And there is laboratory evidence that BPA alternatives have estrogen-like activity. A 2017 study by the US Environmental Protection Agency found that certain alternatives were actually more potent than BPA in activating estrogen receptors in human cells.
In a new study, Jacobson’s team focused on urinary levels of bisphenol S and bisphenol F in more than 1,800 US children and teens. Overall, researchers found that higher levels of these chemicals correlate with higher prevalence. obesity..
Studies show that for each “unit increase” in BPS, the odds of obesity increased by 16% and the likelihood of severe obesity increased by 18%.
On the other hand, BPF was less detected in the urine of children.But when it happened, the odds of excess Tummy fat Increased: Children with detectable BPF had a 29% increased risk of abdominal obesity.
However, none of them prove the cause and effect.
“We need to interpret the findings carefully,” Jacobson said. “I can’t guess it [the chemicals] Causes obesity or Weight gain.. “
Instead, she said, studies show that there is a link between chemicals and obesity. For example, further research is needed to determine if BPA alternatives are associated with children. Weight gain with time.
Dr. Robert Sajisi is an assistant professor of endocrinology at the University of Illinois at Chicago. “It is very important to study these other bisphenols and determine their health effects,” he said.
The “BPA-free” label may seem to mean that the product is safe, but in practice it often contains bisphenols that have not been well studied.
New findings published online on July 25 Journal of the Endocrine SocietyIs based on data from a government health survey conducted between 2013 and 2016.This has 1,831 children teens 6-19 years old.
Almost all urine samples contained BPA, but 88% contained BPS and 55% contained BPF.
Bisphenols are often found in food packaging, so high-level people may eat a lot of processed foods.So Jacobson pointed out that it can be difficult to get the effect of bisphenol out of it. diet..
But she said her team was able to explain the calorie intake of the child. Still, the relationship between bisphenol and obesity remained.
In addition, Sargis said it was not in either or both situations. diet Chemicals “interact” to produce more effects than just one.
If you want to avoid bisphenols, Samara Geller, a non-profit environmental working group, provided the following advice: Reduce processed foods and increase fresh ones. Choose frozen or dried foods over canned foods, or foods sold in place of glass or cans, plasticAvoid hard, clear plastics marked with Recycle Code 7 or “PC”. Request an electronic receipt. Wash your hands after handling the paper receipt.
Jacobson repeated the advice.
“I still don’t know what these are [BPA substitutes] “But if you want to limit your exposure, there are some simple things you can do,” she said.
