Food Industry’s Switch to Non-BPA Linings Still Poses Health Risks
By George Citroner
Bisphenol A (BPA) is well-known for its estrogen-mimicking properties (Trusted Source), and is used in many canned foods. While manufacturers have been removing this compound from their products, new research is showing that the substitute might be just as bad.
Bisphenol S (BPS) and bisphenol F (BPF) are manufactured chemicals now being used to replace the BPA in plastics lining aluminum cans and items like cash-register receipts.
But, according to a study published in the Journal of the Endocrine Society, these two substances are also linked with an increased likelihood of childhood obesity.
Children With Higher Levels Are More Likely to Be Obese
Researchers analyzed data from the U.S. National Health and Nutrition Examination Survey (Trusted Source) to evaluate associations between BPA, BPS, and BPF, and body mass outcomes among children ages 6 to 19.
They found children with higher levels of BPS and BPF in their urine were more likely to be obese compared to those with lower levels.
Asked if she found the findings surprising, study author Melanie Jacobson, PhD, MPH, of NYU School of Medicine, told Healthline, "Unfortunately not. BPF and BPS have almost the same chemical structure as BPA, so we might expect that they could act similarly in the body."
"Previous research has shown similar findings in both children and adults. For example, in a previous study, we found that BPA was associated with a higher prevalence of obesity in U.S. children, and this study found the same trend among these newer versions of that chemical," said Jacobson.
Bisphenol Disrupts the Body’s Metabolism
BPA had already been identified as an obesogen in a 2017 study (Trusted Source).
"An obesogen is a substance that disrupts the endocrine system and the body's metabolism such that it promotes fat accumulation, weight gain, and obesity," Dr. Nagendra Gupta, internist at Texas Health Arlington Memorial, explained.
He continued: "It actually belongs to a class of chemicals, which are known as endocrine disruptors. These chemicals look like and act like hormones, thus confusing the human endocrine system and causing disruption of its normal functions, resulting in a variety of effects, some of which can be harmful."
Exposure to These Chemicals Is Common
"Our study was about exposure to bisphenols, which are synthetic chemicals found in aluminum can linings, plastics, thermal paper receipts, and other consumer products, and their association with obesity among a nationally representative sample of U.S. children and adolescents," said Jacobson.
"We found that children who had greater levels of these chemicals in their urine were more likely to be obese compared with children with lower levels," she said.
"We conducted this study because exposure to these chemicals is very common in the U.S.," she continued. "Bisphenol S and bisphenol F are replacement chemicals for bisphenol A, which has been decreasing in use in recent years due to concern over potential health effects."
"These compounds basically mimic the effects of some hormones such as estrogen and glucocorticoids, which play an important role in metabolism of fat and reproductive health," Gupta said.
Bisphenol’s Are Recognized as Safe By Old FDA Rule
Some chemicals used in the process of packaging or preparing foods, like bisphenol, fall under a U.S. Food & Drug Administration (FDA) rule called Generally Recognized as Safe (GRAS).
This means that substances added to food must be FDA-reviewed unless the substance is "generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use."
The American Academy of Pediatrics said in a policy statement that many of these substances were grandfathered for approval because they were considered GRAS during the 1950s. However, this doesn't consider the impact of chemicals that can be absorbed into food indirectly, such as through dyes or packaging.
The Academy also said "the GRAS process, although intended to be used in limited situations, has become the process by which virtually all new food additives enter the market. Consequently, neither the FDA nor the public have adequate notice or review."
Responding to growing concerns over bisphenol and other chemicals, then-FDA Commissioner Dr. Scott Gottlieb and FDA Deputy Commissioner Anna Abram said in a 2018 statement (Trusted Source): "Food safety is at the core of the agency's mission to protect and promote public health for our nation's consumers. We take seriously our commitment to the consumers and industry who look to the FDA for important guidance when it comes to our nation's food supply, including the safety of substances used in food."
Minimizing Your Exposure to Bisphenols
According to Jacobson, some manufacturers are using naturally-based can liners, such as oleoresin.
"However, without a clear label to differentiate bisphenol from non-bisphenol linings, parents can minimize children's exposure by reducing consumption of processed foods such as canned foods, avoiding thermal paper receipts, and not microwaving polycarbonate plastic food containers."
She cautioned, "Although our study did not examine pregnant women, avoiding exposure to these chemicals is advised given the vulnerability of the fetus to any chemical exposures."
"These chemicals can be present in basically anything. Besides plastics and aluminum cans, BPS is found on a variety of surfaces, such as documents generated from a thermal printer. Likewise, many skin lotions are packaged in plastic bottles that might result in exposure to bisphenol compounds," explained Gupta.
"Given the labeling restrictions confined only to BPA as of now, it is very hard for people to screen for the presence of BPS and BPF in plastics," he said.

When President Donald Trump visited California on September 14 and dismissed the state Secretary of Natural Resources Wade Crowfoot's plea to recognize the role of climate change in the midst of the Golden State's worst and most dangerous recorded fire season to date, he gaslighted the tens of millions of West Coast residents suffering through the ordeal.
Foxes Guarding the Henhouse<p>Before he assumed power, Trump attacked regulations as unnecessary barriers to freedom and economic prosperity. Since taking office, he has targeted anything enacted by the administration of his predecessor, Barack Obama, and taken steps to withdraw the U.S. from the Paris agreement, the international effort to combat climate change. He has also staffed heads of key agencies with climate deniers of various stripes, forced out career public servants and created a hostile work environment for those who don't profess loyalty to his deregulatory agenda.</p><p>Like Trump himself, some of his cabinet choices displayed an audacious penchant for <a href="https://www.nytimes.com/interactive/2020/09/27/us/donald-trump-taxes.html?action=click&module=Spotlight&pgtype=Homepage" target="_blank">self-dealing</a> and abusing their positions of authority. One example is Trump's first Environmental Protection Agency (EPA) Administrator, Scott Pruitt, who aggressively worked to overturn Obama's climate regulations, spent most of his time in <a href="https://www.washingtonpost.com/national/health-science/trump-epa-head-steps-down-after-wave-of-ethics-management-scandals/2018/07/05/39f4251a-6813-11e8-bea7-c8eb28bc52b1_story.html" target="_blank" rel="noopener noreferrer">private meetings</a> with fossil fuel and chemical company executives, sidelined career EPA staff and reconfigured independent scientific advisory boards to make them more supportive of the industries EPA is charged with regulating.

Like Pruitt, Trump's first Interior Secretary Ryan Zinke aggressively attacked environmental regulations, <a href="https://www.washingtonpost.com/news/energy-environment/wp/2017/05/07/epa-dismisses-half-of-its-scientific-advisers-on-key-board-citing-clean-break-with-obama-administration/" target="_blank">ditched more than 200 advisory panels</a>, and pushed to open up vast swaths of public land to oil and gas drilling.

These include repealing Obama's main climate policy, the Clean Power Plan, which was intended to reduce dirty emissions from power plants; increasing pollution from cars by rolling back fuel economy standards and challenging California's longtime authority to set stricter emissions standards; targeting controls on hydrofluorocarbons, powerful greenhouse gases used mainly in refrigerators and air conditioners that also destroy the Earth's protective ozone layer; and allowing unreported and unregulated emissions of methane, another potent greenhouse gas, by oil and gas companies.</p><p>Besides these measures, Trump is also trying to gut core environmental statutes like the Clean Air Act, the Clean Water Act, the National Environmental Policy Act and the Endangered Species Act, all of which were enacted to protect human health and preserve a livable world.</p><p>The Paris agreement aims to keep the rise in average global temperatures at less than 2 degrees Celsius above pre-industrial levels and hopefully cap it at 1.5 degrees C or lower.

It wasn't so long ago that the issue of climate change was poised to play a huge – possibly even a decisive – role in the 2020 election, especially in the race for control of the U.S. Senate. Many people supporting Democratic candidates saw a possible Democratic majority as a hedge against a potential Trump re-election … a way to plug the firehose spray of more than 100 environmental regulation rollbacks and new anti-climate initiatives by the administration over its first term.
Potential Climate Voters<p>In a September 1 memo on climate and the election, Andrew Baumann, vice president of the consultants Global Strategy Group, wrote: "Few issues have seen as dramatic a shift in public opinion as climate change has over the last few years. Only marriage equality and the recent shift in views around racial justice outpace the rapid growth in the salience of climate change as an issue."</p><p>Calling it a "winning political issue" the memo says: "First, it is clearly a motivator for both younger and Latinx voters. Second, it has the power to move swing voters, particularly center-right white women."</p><p>Baumann points to a finding that when a group of such women were asked generic ballot questions, Democrats trailed by nine percentage points. But when the question was revised as a choice between:</p><p>"A Democrat who supports taking strong government action to combat climate change.<br>A Republican who opposes taking strong government action to combat climate change."</p><p>… the result was a 29 percentage point shift, putting Democrats ahead by 20 percentage points among that same group.</p><p>"I think it is playing a role," says Senator Sheldon Whitehouse, D-RI, a longtime outspoken climate activist who is on the Senate Environment and Public Works Committee and also on the Senate Democrats' Special Committee on the Climate Crisis. If Democrats win back the Senate, he stands to play an even more pivotal climate role as part of the majority. He is not up for re-election this year.</p><p><span></span>"I think from the Democratic side it's playing a role in generating enthusiasm – particularly making younger voters feel that they have a real stake in this election. On the Republican side, I think things have moved enough that candidates can no longer get away with simply scoffing about climate change."</p>
Climate a Top Concern for Youths, Latinx<p>So who's still thinking climate? Mostly young voters – 18 to 25 or 29 and Latinx voters.</p><p>Climate and the environment are the top concern among young voters, just above racism and healthcare according to <a href="https://circle.tufts.edu/latest-research/poll-young-people-believe-they-can-lead-change-unprecedented-election-cycle" target="_blank" rel="noopener noreferrer">CIRCLE</a>, the Center for Information and Research on Civic Learning and Engagement at Tufts University, which focuses on the political life of young people in the U.S. For Latinx youth, it drops a bit but remains in the top three.</p><p>The issues young people care about have an impact on how they volunteer their time, says Kristian Lundberg, an associate researcher at CIRCLE. He says that's played out most notably through the Sunrise Movement, which focuses on climate change and the environment along with other key activist groups such as Black Lives Matter and March for Our Lives.</p><p>He points to polling this summer that showed that 83% of 18-to-29-year-olds felt they had the power to change things. "Young people feel much more empowerment than in 2016 and 2018," Lundberg says. "It's intentional these movements are carving out space for young people. It's an important strategy."</p><p>In positions of power in these organizations, young people have developed peer-to-peer outreach on activism. And Lundberg says young people have made the leap that connects activism to voting as a lever for change. "In the past in very close races, young people breaking heavily have provided the margin of victory," he says.</p><p>CIRCLE is highlighting 10 U.S. Senate races as ones in which young voters can be decisive. Several of them have notable climate or environmental components – most prominently the Colorado and Montana races.</p><p>The Republican incumbents in each state – Cory Gardner in Colorado and Steve Daines in Montana – are running against a popular Democratic governor – John Hickenlooper in Colorado, now out of office — and Steve Bullock, still the governor of Montana. Both governors have had to balance their state's fossil fuel economic interests with supporting climate change solutions.</p>
Tying Climate Change to the Economy<p>In August, Data for Progress, a progressive research think tank, released polling on climate change – including in the battleground Senate elections in Arizona, Iowa, Maine, and North Carolina – showing voters back a Senate candidate supporting strong climate action.</p><blockquote>Climate change as 'mobilizing issue … key persuasion issue.'<br></blockquote><p>It also showed that linking climate change to the economy may be key. That means talking about clean energy and jobs together, says Danielle Deiseroth, climate data analyst for <a href="https://circle.tufts.edu/latest-research/poll-young-people-believe-they-can-lead-change-unprecedented-election-cycle" target="_blank">Data for Progress</a>. She says that in addition to jobs, climate change issues include climate justice and economic equality – both of heightened interest because of fallout from western wildfires.</p><p>"Climate change, we've observed over the last year or so, is a key mobilizing issue and a key persuasion issue," she says. "Climate issues can only grow support for Democratic candidates.</p><p>"I think it's pretty naive to say climate is the key issue for voters. For a lot of voters it really exemplifies so many things that are wrong with the Trump presidency," Deiseroth says.</p><p>So a factor among others. Helpful, but pivotal only in narrow circumstances.</p><p>At the League of Conservations Voters, a progressive environmentalist organization putting a lot of money and effort into the 2020 races, Senior Director of Political Affairs Craig Auster says: "I'll push back that climate change doesn't matter or isn't registering."</p><p>"It's still showing up in several Senate races. It's been playing a role in almost all of them."</p><p>Candidates are still talking about it, he says, pointing to Colorado, Montana, Iowa, and other states where ads are addressing climate and environmental issues. That shows the candidates believe their opponent is vulnerable on the issue or they're strong on it, he says.</p><p>Like others, Auster calls climate a motivator.</p><p>"Climate change matters," he says. "We have proof point after proof point about what's happening, whether it's a hurricane, a superstorm, derechos in Iowa, or wildfires out west.</p><p>"Pre-COVID it was top tier for Democratic voters along with healthcare. If COVID didn't happen I think climate would be a big deal."</p>
