Doctors worry that iodine deficiency — a dietary problem from the past — is coming back

NEW YORK (AP) — The 13-year-old boy came to the clinic with a rapidly ballooning neck. Doctors were puzzled.

Testing ruled out their first suspicion. But further tests pinpointed what they — and the boy — had been missing: iodine.

A century ago, iodine deficiency affected kids across large swaths of the country. It essentially disappeared after some food makers started adding it to table salt, bread and some other foods, in one of the great public health success stories of the 20th century.

But today, people are getting less iodine because of changes in diet and food manufacturing.

Although most people are still getting enough, researchers have increasingly been reporting low levels of iodine in pregnant women and other people, raising concerns about an impact on their newborns. And there is also a very small, but growing, number of reports of iodine deficiency in kids.

“This needs to be on people’s radar,” said Dr. Monica Serrano-Gonzalez, a Brown University doctor who treated the boy in 2021 in Providence, Rhode Island.

Iodine is a trace element found in seawater and in some soils — mostly in coastal areas. A French chemist accidentally discovered it in 1811 when an experiment with seaweed ash created a purple puff of vapor. The name iodine comes from a Greek word meaning violet-colored.

Later that century, scientists began to understand that people need certain amounts of iodine to regulate their metabolism and stay healthy, and that it’s crucial in the development of brain function in children.

One sign of insufficient iodine is a swelling of the neck, known as a goiter. The thyroid gland in the neck uses iodine to produce hormones that regulate the heart rate and other body functions. When there's not enough iodine, the thyroid gland enlarges as it goes into overdrive to make up for the lack of iodine.

At the beginning of the 20th century, goiter was very common in children in certain inland parts of the United States, especially in a “goiter belt” that stretched from Appalachia and the Great Lakes to the northwest United States. Some of the kids were unusually short, deaf, intellectually stunted and had other symptoms of a syndrome once known as “cretinism.”

Public health experts realized they couldn't solve the problem by feeding everyone seaweed and seafood, but they learned that iodine can essentially be sprayed on table salt. Iodized salt first became available in 1924. By the 1950s, more than 70% of U.S. households used iodized table salt. Bread and some other foods also were fortified with iodine, and iodine deficiency became rare.

But diets changed. Processed foods now make up a large part of the American diet, and though they contain a lot of salt, it's not iodized. Leading bread brands no longer add iodine. In the case of the 13-year-old boy, he has mild autism and was a fussy eater, mostly only eating specific brands of bread and peanut butter.

And for people who do salt their food, the fashion now is to use kosher salt, Himalayan rock salt or other noniodized products.

“People have forgotten why there's iodine in salt,” said Dr. Elizabeth Pearce of Boston Medical Center. She is a leader in the Iodine Global Network, a nongovernmental agency working to eliminate iodine deficiency disorders.

She noted a reported 50% drop in U.S. iodine levels in surveyed Americans between the 1970s and the 1990s.

Though iodine consumption is falling overall, most Americans are still getting enough through their diet, experts say. But doctors worry that's not the case for women and children, who are most vulnerable to iodine deficiency.

The American Academy of Pediatrics and other medical societies recommend that all pregnant and breastfeeding women get 150 micrograms of iodine each day. You can get that from one-half to three-quarters of a teaspoon of iodized table salt.

In the last 15 years or so, U.S. researchers have increasingly reported seeing mild iodine deficiency in pregnant women. A Michigan State University study of about 460 pregnant women in the city of Lansing found about a quarter of them were not getting enough.

Many prenatal vitamins don't contain iodine, noted Jean Kerver, the study's lead author. That's why doctors recommend that pregnant or breastfeeding women check labels to ensure they are taking multivitamins or prenatal supplements with iodine.

Some studies have linked even mild iodine deficiency to lower IQs and language delay in children, although there is debate about at exactly what levels problems start, Pearce said.

Experts say there hasn't been enough research to establish what impact that iodine deficiency has actually been having on the U.S. population in recent years.

Serrano-Gonzalez said she and her colleagues have seen four other cases in children in their clinic in Providence.

“We’re concerned this may be increasing, especially in patients with restricted diets," she said.

NEW YORK (AP) — President-elect Donald Trump was denied Tuesday in his second attempt to delay this week's sentencing in his hush money case.

A New York appeals court judge swiftly rejected Trump's request for an order that would put off sentencing while he appeals a decision last week upholding the verdict. It remains on schedule for Friday, though he can still ask other courts to intervene.

Judge Ellen Gesmer issued a one-sentence ruling after an emergency hearing in the Appellate Division of the state’s trial court. She did not give a reason for her decision. Trump did not attend the hearing.

Trump, fighting to avoid the finality of his conviction before he returns to the White House, turned to the Appellate Division after the trial judge, Juan M. Merchan, on Monday rebuffed his initial bid to indefinitely postpone sentencing.

At the emergency hearing, Trump lawyer Todd Blanche argued that Trump can’t be sentenced because, as president-elect, he enjoys the same immunity from criminal proceedings as a president.

Merchan had rejected that idea in his ruling last week and Steven Wu, arguing for the Manhattan district attorney’s office, said it flew in the face of the long-held concept of one president at a time.

Asked by Gesmer if he could cite anything to support his position, Blanche said: “There’s never been a case like this before.” But, citing a longstanding Justice Department memorandum on presidential immunity, Blanche said, “everybody agrees that President Trump is entitled to complete immunity from any criminal process” once he takes office.

Merchan has suggested he will not sentence Trump to jail time or any punishment, but Blanche said that isn't binding and asked Gesmer: “If Judge Merchan were to sentence President Trump to 11 days in prison, would the court say, ‘OK now we need to step in?’”

Trump, whose sentencing will be held 10 days before his inauguration, is poised to be the first president to take office convicted of crimes. If his sentencing doesn’t happen before his second term starts Jan. 20, presidential immunity could put it on hold until he leaves office.

Merchan has signaled that he is not likely to punish Trump for his conviction on 34 felony counts of falsifying business records and will accommodate the transition by allowing him to appear at sentencing by video, rather than in person at a Manhattan courthouse.

Still, the Republican and his lawyers contend that his sentencing should not go forward because the conviction and indictment should be dismissed. They have previously suggested taking the case all the way to the U.S. Supreme Court.

Merchan last Friday denied Trump’s request to throw out his conviction and dismiss the case because of his impending return to the White House, ruling that Trump’s current status as president-elect does not afford him the same immunity from criminal proceedings as a sitting president.

Merchan wrote that the interests of justice would only be served by “bringing finality to this matter” through sentencing. He said giving Trump what’s known as an unconditional discharge — closing the case without jail time, a fine or probation — “appears to be the most viable solution.”

In his filing Tuesday, Blanche argued that Merchan's interpretation of presidential immunity was wrong and that it should extend to a president-elect during “the complex, sensitive process of presidential transition.”

“It is unconstitutional to conduct a criminal sentencing of the president-elect during a presidential transition, and doing so threatens to disrupt that transition and undermine the incoming president’s ability to effectively wield the executive power of the United States,” Blanche wrote.

Trump’s lawyers are also challenging the judge's prior decision rejecting Trump’s argument that the case should be thrown out because of the U.S. Supreme Court’s ruling last July that gave presidents broad immunity from prosecution.

Manhattan prosecutors have pushed for sentencing to proceed as scheduled, “given the strong public interest in prompt prosecution and the finality of criminal proceedings.”

Trump was convicted last May on charges involving an alleged scheme to hide a hush money payment to porn actor Stormy Daniels in the last weeks of Trump’s 2016 campaign to keep her from publicizing claims she’d had sex with him years earlier. He says that her story is false and that he did nothing wrong.

The case centered on how Trump accounted for reimbursing his then-personal lawyer Michael Cohen, who had made the payment to Daniels. The conviction carried the possibility of punishment ranging from a fine or probation to up to four years in prison.

Trump’s sentencing initially was set for last July 11, then postponed twice at the defense’s request. After Trump’s Nov. 5 election, Merchan delayed the sentencing again so the defense and prosecution could weigh in on the future of the case.
