A new study has found that a low-fat vegan diet—regardless of how processed the food is—can significantly reduce hot flashes and promote weight loss.
The research, conducted by The Menopause Society and published in the journal Menopause, explored how plant-based eating can benefit women in midlife.
"This study highlights the potential positive effects of a plant-based diet rich in soy, regardless of the level of processing, in terms of both hot flash and weight management," Dr. Stephanie Faubion, medical director for The Menopause Society, said in a statement.
"Given these and the other known benefits in terms of lowering heart disease and cancer risk, women in midlife should consider leaning into a plant-based diet."

The study followed existing data that found a plant-based diet can reduce hot flashes, in part by aiding with weight loss.
But with many plant-based foods being highly-processed, the Ohio-based society wanted to find out whether the type of food consumed, be it vegan, ultra-processed or animal-based, affected hot flash severity.
Participants in the trial were randomly assigned to follow either a low-fat vegan diet supplemented with soybeans or an omnivorous diet under supervision. Both groups reported similar levels of hot flash frequency and severity at the outset.
Over a 12-week period, those in the vegan group reported a 92 percent reduction in severe hot flashes. Their average weight loss was 3.6 kilograms, compared to a negligible 0.2 kilogram change in the omnivorous control group.
Significantly, the benefits in the vegan group remained consistent whether their food was minimally processed or highly processed, indicating that the critical factor was the source of the food—plant-based versus animal-based—rather than the degree of processing.
The findings challenge traditional views that all processed foods are detrimental to health, at least within the context of a vegan diet.
For alternative ways to manage hot flashes, Newsweek spoke with Tonie Reincke, M.D., a Texas-based specialist in interventional radiology who has experienced hot flashes firsthand.
"Speaking not only as a physician, but also as a woman who has experienced hot flashes, several things that I found helpful to reduce these include layering my clothing to quickly cool down, carrying a portable fan, and drinking ice water throughout the day," Reincke said.
"Herbal supplements such as black cohosh and primrose oil may help some women, though results can vary, and hormone replacement therapy is an option under medical supervision."

Woman Claims Marine Laced Her Drink With Abortion Pills
A Texas woman accused a U.S. Marine in a lawsuit on Monday of lacing her drink with abortion pills, terminating her pregnancy against her wishes. The woman, Liana Davis, 37, claims that Christopher Cooprider, 34, a U.S. Marine Corps Captain from Arizona who she says impregnated her, secretly dissolved 10 pills of misoprostol, a drug used in medical abortions, in a hot chocolate he made for her on April 5. She made the accusation in a civil complaint filed in a federal court in Texas.. Shortly after drinking the beverage, the complaint says, Ms. Davis began bleeding and went to the hospital, where she lost her pregnancy. The lawsuit also names Aid Access, a major seller of abortion pills online, as a defendant. Ms. Davis said in the lawsuit that Mr. Cooprider used Aid Access to obtain the pills. The suit named the founder of Aid Access, the Dutch physician Rebecca Gomperts, as a third defendant. Mr. Cooprider, a flight student with the U.S. Marines in Corpus Christi, Texas, declined to comment on the lawsuit or say if he had a lawyer. The U.S. Marine Corps said in a statement that it was aware of a civil lawsuit involving one of its aviation students but that no additional information was available. In a statement, Dr. Gomperts pointed to Aid Access's role in providing 'essential, lifesaving health care' for vulnerable women. Ms. Davis became pregnant by Mr. Cooprider in early 2025, the lawsuit claims. Text messages included in the lawsuit and said to be from Ms. Davis to Mr. Cooprider describe the pregnancy as 'unplanned.' In one message she called herself Mr. Cooprider's 'mistress.' The lawsuit says that Ms. Davis has three children with her husband, with whom she was in divorce proceedings. According to the messages, Mr. Cooprider told Ms. Davis that he wanted her to have an abortion, even before she had confirmed her pregnancy with a test. Ms. Davis texted Mr. Cooprider on Jan. 31, 2025, for his thoughts on her possible pregnancy, and he responded, 'Get rid of it,' the lawsuit said. Mr. Cooprider added that the two were not in love or a couple, and that bringing a child into the world would be 'messed up,' according to the lawsuit. On Feb. 3, Mr. Cooprider sent a text message saying that if the pregnancy test was 'positive then we need to schedule a clinic visit and get an abortion pill asap,' according to the complaint. On Feb. 5, Mr. Cooprider texted Ms. Davis and said he was going to order abortion pills for her, according to the complaint, a step it said Ms. Davis opposed. On Feb. 6, Mr. Cooprider purchased pills from Aid Access, according to the lawsuit. 'I'm not OK with you buying something like that w/o my permission,' Ms. Davis wrote him, according to the complaint. Mr. Cooprider brought the pills to Ms. Davis's home and repeatedly asked her to take them, according to the lawsuit. Pictures included in the lawsuit show two containers of abortion drugs labeled 'Chris Cooprider.' The text exchanges grew more heated over several weeks, then took an abrupt turn. In early April, the lawsuit says, Mr. Cooprider texted Ms. Davis to propose a 'trust building night' where he would make them 'warm relaxing tea.' Mr. Cooprider went to Ms. Davis's home on April 5, where he made her a hot chocolate, according to the lawsuit. Ms. Davis was eight weeks pregnant at the time, the lawsuit said. According to the lawsuit, she began hemorrhaging and cramping within 30 minutes of drinking the beverage. Mr. Cooprider said he would drive to get Ms. Davis's mother, who lived nearby, the lawsuit said. The plan was that she would mind Ms. Davis's three children, and Mr. Cooprider could then drive Ms. Davis to the emergency room. But after leaving to get Ms. Davis's mother around 12:10 a.m., Mr. Cooprider stopped responding to calls and texts, and did not pick her up, according to the lawsuit. Screenshots of text messages included in the lawsuit show Ms. Davis repeatedly texting Mr. Cooprider, including one sent at 12:34 a.m. saying: 'I'm gushing blood. Please hurry.' Ms. Davis sent her mother money for an Uber just before 1 a.m., around the same time Mr. Cooprider responded to the text messages, the lawsuit said. He apologized and told her he had a flight in the morning, according to the complaint, and then stopped answering. Before leaving the house, Ms. Davis found the opened packets of pills, the lawsuit said. A neighbor drove Ms. Davis to a Bay Area hospital's emergency room, where she lost the pregnancy, according to the complaint. Ms. Davis brought the pill bottles with her to the emergency room and gave them to the Corpus Christi Police Department, according to the lawsuit. The Police Department said a detective investigated the allegations and shared the results with the Nueces County District Attorney's Office. 'After careful review, both agencies concluded that the elements of a crime could not be established, and the investigation was subsequently closed as unfounded,' Madeline Vaughn, a spokeswoman with the department, said in a statement. Ms. Davis's suit seeks punitive damages from the defendants. It did not give a figure, but said the amount was greater than $75,000. Sheelagh McNeill contributed research.

Trump's Approval Rating With Medicaid Recipients Takes a Nosedive: Poll
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. President Donald Trump's approval rating with Medicaid recipients has dropped a staggering 16 points since January, a new poll from Morning Consult shows on Thursday. Why It Matters The shift occurred as Republicans advanced major cuts to Medicaid in the party's signature budget legislation, a bill the president dubbed "the big, beautiful bill." Medicaid covers more than 71 million low-income Americans and serves as a cornerstone of health coverage for vulnerable populations. Recently, the Centers for Medicare & Medicaid Services (CMS) and Department of Homeland Security (DHS) reached an agreement that provided U.S. Immigration and Customs Enforcement (ICE) access to certain Medicaid user data, a move that raised privacy and access-to-care concerns among advocates and some officials. Critics warned that such measures could deter eligible patients from seeking care. What To Know In the poll, the president's approval rating with the group is 36 percent, a drop from 52 percent during the president's first week in office. Trump's disapproval mark is 55 percent, soaring from 34 percent during the same time frame. Morning Consult conducts the surveys weekly among 14,695 U.S. adults, including 3,134 Medicaid recipients. The poll has a margin of error of 1 percent to 2 percent. The survey noted that "The biggest political question facing the Republican Party ahead of the next couple of election cycles is whether it can consolidate gains made in recent years among lower-income Americans. In the wake of those Medicaid cuts, that sure looks like a very steep climb," Cameron Easley, Morning Consult's head of U.S. Political Analysis, wrote. The president's overall approval rating with U.S. adults in the poll is 44 percent compared to a 50 percent disapproval rating.

(Photo by) What People Are Saying Political analyst Craig Agranoff told Newsweek via text message on Thursday: "The notable decline in his approval rating among Medicaid recipients, signals growing discontent within a key demographic reliant on public health programs. This drop, sharper than among the general public, appears tied to Republican led efforts to cut Medicaid funding through legislation like the One Big Beautiful Bill Act, which accelerated the slide when proposed in March and enacted in July. "It's particularly concerning for the GOP, as it erodes support even among Republican and independent Medicaid users, potentially complicating efforts to maintain gains with working class voters ahead of midterms. If unaddressed, this could highlight vulnerabilities in Trump's coalition where policy impacts clash with economic promises." Independent Senator Bernie Sanders of Vermont posted to X on Wednesday: "Trump's 'Big, Beautiful Bill' is a direct attack on the 1 in 3 Americans with disabilities who rely on Medicaid for their health care. It cannot stand. We must work together until every American with a disability has the freedom, opportunity and respect that they deserve." Trump wrote on Truth Social in May: "Republicans MUST UNITE behind, 'THE ONE, BIG BEAUTIFUL BILL!' Not only does it cut Taxes for ALL Americans, but it will kick millions of Illegal Aliens off of Medicaid to PROTECT it for those who are the ones in real need. The Country will suffer greatly without this Legislation, with their Taxes going up 65%. It will be blamed on the Democrats, but that doesn't help our Voters. We don't need 'GRANDSTANDERS' in the Republican Party. STOP TALKING, AND GET IT DONE! It is time to fix the MESS that Biden and the Democrats gave us. Thank you for your attention to this matter!" What Happens Next The president's approval rating will continue to be tracked by numerous outlets and pollsters leading up to the 2026 midterm election season.

High Cost of Cheap Coal: The Coal Paradox
A coal train rumbling across Montana is a mile and a half (2.4 kilometers) long yet carries barely a day's fuel for a large power plant. The U.S. burns more than a billion tons of coal a year. Photograph by William Campbell/Corbis Learn about the high cost of cheap coal, including pollution and global warming. On a scorching August day in southwestern Indiana, the giant Gibson generating station is running flat out. Its five 180-foot-high (54.9-meter-high) boilers are gulping 25 tons (22.7 metric tons) of coal each minute, sending thousand-degree steam blasting through turbines that churn out more than 3,000 megawatts of electric power, 50 percent more than Hoover Dam. The plant's cooling system is struggling to keep up, and in the control room warnings chirp as the exhaust temperature rises. But there's no backing off on a day like this, with air conditioners humming across the Midwest and electricity demand close to record levels. Gibson, one of the biggest power plants in the country, is a mainstay of the region's electricity supply, pumping enough power into the grid for three million people. Stepping from the sweltering plant into the air-conditioned offices, Angeline Protogere of Cinergy, the Cincinnati-based utility that owns Gibson, says gratefully, "This is why we're making all that power." Next time you turn up the AC or pop in a DVD, spare a thought for places like Gibson and for the grimy fuel it devours at the rate of three 100-car trainloads a day. Coal-burning power plants like this one supply the United States with half its electricity. They also emit a stew of damaging substances, including sulfur dioxide—a major cause of acid rain—and mercury. And they gush as much climate-warming carbon dioxide as America's cars, trucks, buses, and planes combined. Here and there, in small demonstration projects, engineers are exploring technologies that could turn coal into power without these environmental costs. Yet unless utilities start building such plants soon—and lots of them—the future is likely to hold many more traditional stations like Gibson. Last summer's voracious electricity use was just a preview. Americans' taste for bigger houses, along with population growth in the West and air-conditioning-dependent Southeast, will help push up the U.S. appetite for power by a third over the next 20 years, according to the Department of Energy. And in the developing world, especially China, electricity needs will rise even faster as factories burgeon and hundreds of millions of people buy their first refrigerators and TVs. Much of that demand is likely to be met with coal. For the past 15 years U.S. utilities needing to add power have mainly built plants that burn natural gas, a relatively clean fuel. But a near tripling of natural gas prices in the past seven years has idled many gas-fired plants and put a damper on new construction. Neither nuclear energy nor alternative sources such as wind and solar seem likely to meet the demand for electricity. Where guests are guardians Meanwhile, more than a quarter trillion tons of coal lie underfoot, from the Appalachians through the Illinois Basin to the Rocky Mountains—enough to last 250 years at today's consumption rate. You hear it again and again: The U.S. is the Saudi Arabia of coal. About 40 coal-burning power plants are now being designed or built in the U.S. China, also rich in coal, could build several hundred by 2025. Mining enough coal to satisfy this growing appetite will take a toll on lands and communities. Of all fossil fuels, coal puts out the most carbon dioxide per unit of energy, so burning it poses a further threat to global climate, already warming alarmingly. With much government prodding, coal-burning utilities have cut pollutants such as sulfur dioxide and nitrogen oxides by installing equipment like the building-size scrubbers and catalytic units crowded behind the Gibson plant. But the carbon dioxide that drives global warming simply goes up the stacks—nearly two billion tons of it each year from U.S. coal plants. Within the next two decades that amount could rise by a third. There's no easy way to capture all the carbon dioxide from a traditional coal-burning station. "Right now, if you took a plant and slapped a carbon-capture device on it, you'd lose 25 percent of the energy," says Julio Friedmann, who studies carbon dioxide management at Lawrence Livermore National Laboratory. But a new kind of power station could change that. A hundred miles (161 kilometers) up the Wabash River from the Gibson plant is a small power station that looks nothing like Gibson's mammoth boilers and steam turbines. This one resembles an oil refinery, all tanks and silvery tubes. Instead of burning coal, the Wabash River plant chemically transforms it in a process called coal gasification. The Wabash plant mixes coal or petroleum coke, a coal-like residue from oil refineries, with water and pure oxygen and pumps it into a tall tank, where a fiery reaction turns the mixture into a flammable gas. Other equipment removes sulfur and other contaminants from the syngas, as it's called, before it's burned in a gas turbine to produce electricity. Cleaning the unburned syngas is cheaper and more effective than trying to sieve pollutants from power plant exhaust, as the scrubbers at a plant like Gibson do. "This has been called the cleanest coal-fired power plant in the world," says Steven Vick, general manager of the Wabash facility. "We're pretty proud of that distinction." The syngas can even be processed to strip out the carbon dioxide. The Wabash plant doesn't take this step, but future plants could. Coal gasification, Vick says, "is a technology that's set up for total CO2 removal." The carbon dioxide could be pumped deep underground into depleted oil fields, old coal seams, or fluid-filled rock, sealed away from the atmosphere. And as a bonus, taking carbon dioxide out of the syngas can leave pure hydrogen, which could fuel a new generation of nonpolluting cars as well as generate electric power. The Wabash plant and a similar one near Tampa, Florida, were built or refurbished with government money in the mid-1990s to demonstrate that gasification is a viable electricity source. Projects in North Dakota, Canada, the North Sea, and elsewhere have tested the other parts of the equation: capturing carbon dioxide and sequestering it underground. Researchers say they need to know more about how buried carbon dioxide behaves to be sure it won't leak back out—a potential threat to climate or even people. But Friedmann says, "For a first cut, we have enough information to say, 'It's a no-brainer. We know how to do this.'" Yet that's no guarantee utilities will embrace the gasification technology. "The fact that it's proved in Indiana and Florida doesn't mean executives are going to make a billion-dollar bet on it," says William Rosenberg of Harvard's Kennedy School of Government. The two gasification power plants in the U.S. are half the size of most commercial generating stations and have proved less reliable than traditional plants. The technology also costs as much as 20 percent more. Most important, there's little incentive for a company to take on the extra risk and expense of cleaner technology: For now U.S. utilities are free to emit as much carbon dioxide as they like. Cinergy CEO James Rogers, the man in charge of Gibson and eight other carbon-spewing plants, says he expects that to change. "I do believe we'll have regulation of carbon in this country," he says, and he wants his company to be ready. "The sooner we get to work, the better. I believe it's very important that we develop the ability to do carbon sequestration." Rogers says he intends to build a commercial-scale gasification power plant, able to capture its carbon dioxide, and several other companies have announced similar plans. The energy bill passed last July by the U.S. Congress offers help in the form of loan guarantees and tax credits for gasification projects. "This should jump-start things," says Rosenberg, who advocated these measures in testimony to Congress. The experience of building and running the first few plants should lower costs and improve reliability. And sooner or later, says Rogers, new environmental laws that put a price on carbon dioxide emissions will make clean technology look far more attractive. "If the cost of carbon is 30 bucks a ton, it's amazing the kinds of technologies that will evolve to allow you to produce more electricity with less emissions." If he's right, we may one day be able to cool our houses without turning up the thermostat on the entire planet.
