TikTokers are obsessed with ‘fibermaxxing'. Here's what the experts say
Break out the chia pudding! The social media trend known as 'fibermaxxing' wants you to add more fiber to your daily diet. TikTok users tout the health benefits of including simple foods packed with the carbohydrate, including the relieving effects in the bathroom. Some TikTokers point to the recent rise in rates of colon cancer in young people, and note that eating fiber can help reduce the risk. To 'fibermaxx,' they're eating more chia seeds in their yogurt bowls, making meals with more beans, and taking supplements. While nutritionists are largely supportive of the trend, they have a few caveats. 'More isn't always better,' Mascha Davis, a registered dietician nutritionist and the owner of Nomadista Nutrition, told Health this week. 'Many people don't get enough fiber, but it's just important to be thoughtful about how you're doing it so that it's not too much too fast,' Kate Mintz, a registered dietitian at U.C.L.A. Health, also recently told The New York Times. Fiber is often used to fight constipation, helping stools to pass easier. 'Even if you suffer from constipation, increasing fiber all at once could make the situation worse before you get cleared out,' Jennifer House, a dietitian and founder of First Step Nutrition, also explained to Health. Getting too much fiber could lead to a bloated and uncomfortable experience, according to the Mayo Clinic. People need to be careful and methodical, and talking to a physician can help to determine what's a right amount, on a case by case basis. What's more, when people with autoimmune conditions such as Crohn's disease see symptoms flare up, they may need to eat less fiber to help manage symptoms. After stomach or intestinal surgery, doctors may also instruct you to keep a lower fiber diet that lets your digestive system heal. Before a colonoscopy the advice may be similar, helping to clear out the large intestine to ensure a successful procedure. But in general, Americans aren't getting enough fiber - more than 90 percent of women and 97 percent of men do not meet the recommended daily intakes. Total dietary fiber intake should be 25 to 30 grams a day from food, and not supplements, according to UCSF Health. Currently, dietary fiber intakes among American adults average about only 15 grams a day. Fiber is good for your gut, heart, and brain, and may also slash the risk of type 2 diabetes and heart disease. The Mayo Clinic recommends adding fiber to the diet slowly over a few weeks, letting the natural bacteria in your digestive system adjust to the change. Staying hydrated is also crucial and fiber works best when it absorbs water. So, what can you eat to fiber to the max? The next time you're at the grocery store, pick up some popcorn, beans, cereal, apples, oranges, peas, cauliflower, or carrots. Raspberries are a particularly fiber-rich fruit, packed with eight grams. "If you're going to have a cookie, have an oatmeal cookie," Joanne Slavin, a professor of food science and nutrition at the University of Minnesota, told the American Heart Association. "It doesn't take large amounts of fiber to have a real effect.'

Trump is all-in on AI sandboxes. Do they work?
With help from Anthony Adragna Among the many, many ambitious ideas baked into his AI Action Plan, President Donald Trump wants to inculcate a 'try-first' culture for innovation in the U.S. The plan, released Wednesday, includes a strong push for industries to hurry up with adopting AI — arguing that 'many of America's most critical sectors,' notably health care, have been slow to integrate it into their operations. And when it comes to the nitty-gritty of how this is supposed to happen, the White House suggests a classic tech-world mechanism: Regulatory sandboxes. 'Sandbox' is a term that gets thrown around a lot in tech, usually referring to a closed environment to test software. When talking about policy, a sandbox is a little different: It essentially gives companies a temporary hall pass on pre-existing regulations — like those for medical devices or data privacy — to pilot new technologies to the public. The idea is that, based on data collected during the trial period, companies can adjust their product designs, and governments can tailor their technology regulations. Federal agencies have previously implemented sandboxes for emerging tech, most notably in financial services. The action plan calls on the Food and Drug Administration and other agencies to establish similar programs for AI — though it's unclear where the funding will come from. Sandboxes for AI systems have already popped up in various states. Last year, Utah enacted a law that has allowed companies to run some tryouts: The ElizaChat platform got approval for a 12-month trial of mental health chatbots, and a firm called Dentacor was allowed to test AI-enabled radiograph diagnostic tools. Texas signed similar legislation into law in June, as did Delaware on Wednesday. To many free-marketers, sandboxes can achieve multiple aims — developing technology, and also putting pressure on regulations to adapt. 'Just because we've been regulating one way for a long, long time doesn't mean we always have to,' Adam Thierer, senior fellow at the R Street Institute, told DFD. 'We can try to find ways to innovate within boundaries – that's what sandboxes are.' Others are skeptical of the whole argument that somehow industry is slow-rolling AI, and needs a government-sanctioned space to try things out. 'Companies aren't held back by lack of permission to test AI,' said Lexi Reese, a former Google VP who ran for Congress in California on a tech-centric platform in 2023. 'They're already deploying it without oversight.' Sandboxes have also been used in the fintech sector for at least a decade, allowing institutions like banks to test out digital systems with real customers. Trump's action plan notably pushed forward on this as well, urging the Securities and Exchange Commission to develop more programs to allow financial firms to test out AI. Hilary Allen, a law professor at American University who specializes in sandboxes, considers herself a skeptic: She said the fintech experience indicates that the downsides of sandboxes outweigh the potential benefits for AI innovations, since they often lead to regulatory capture. 'Sandboxes have been a disappointment, and a lot of regulatory agencies are moving away from them in the fintech space,' she told DFD. She said there's little evidence that these regimes, which are expensive to implement, lead to more sophisticated policies. Instead, what ends up happening is that these sandbox periods stretch on indefinitely, since pilot businesses may grow to a point where agencies are hesitant to shut them down by reinstating regulations. Effectively, the experiment becomes permanent, even without guardrails. (She suggests that clear rules for sunsetting the experiments could help to mitigate the problem.) 'Regulators are in an awkward position,' she said, 'because they become sort of a cheerleader for the firm they have selected, and that leads to natural capture dynamics. Plus, AI companies often skirt regulations in the first place. What the sandboxes really do, said Allen, is attract investors, who get interested because it indicates that an AI company is getting favorable legal treatment. Victoria LaCivita, a spokesperson for the White House's Office of Science and Technology Policy, did not respond directly to Allen's concerns when asked by DFD. But she said in a statement that the administration was fostering 'a pro innovation environment that will foster positive, transformative uses of AI.' Despite the skeptics, sandboxes are still a go-to tool for governments around the world. Even the tech policy hardliners in the European Union have included a sandbox provision in the otherwise strict AI Act. 'The fact that the U.S. is following suit is a wonderful sign,' said Kevin Cochrane, CMO of the global cloud company Vultr. 'Every national government needs to accelerate up policy around AI.' COTTON'S PUSH ON CHINESE ENGINEERS AT DOD The Republican chair of Senate Intelligence is demanding answers from the Defense Department after Microsoft was found to be using China-based engineers to support DOD cloud computing, as ProPublica reported In a letter obtained Thursday by POLITICO, Sen. Tom Cotton (R-Ark.) told Defense Secretary Pete Hegseth, 'we must put in place the protocols and processes to adopt innovative technology quickly, effectively and safely.' Specifically, Cotton asked Hegseth for details on a two-week review of the Defense Department's current cloud contracts; all security classification guides given to Microsoft or other subcontractors; and plans for an agency-wide review of contracting practices to ensure against 'leveraging loopholes' that place systems at risk. Microsoft declined to comment on Cotton's letter. The Defense Department did not immediately respond to POLITICO's inquiry. TikTok won't get more extensions Commerce Secretary Howard Lutnick says that TikTok will have to go offline in the U.S. if China doesn't accept the administration's deal for the app's sale. 'You can't have Chinese control and have something on 100 million American phones,' Lutnick told CNBC Thursday. He added that the proposed deal has been sent to Chinese officials, and that TikTok is an 'unofficial' part of current trade negotiations with Beijing. TikTok did not immediately respond to DFD's inquiry. The app has been a perpetual headache for Trump since he took office. He thrice extended a deadline that Congress set in 2024 for buyers from a nonadversarial country to take majority ownership of TikTok. The administration has been negotiating for months with China and ByteDance, TikTok's Beijing-based parent company. They almost reached a deal in April, but Chinese officials walked away when Trump announced a slew of new tariffs on the country. Trump has reportedly gathered a consortium of U.S. buyers like Oracle for the deal, though Blackstone withdrew its involvement in July. post of the day THE FUTURE IN 5 LINKS Stay in touch with the whole team: Aaron Mak (amak@ Mohar Chatterjee (mchatterjee@ Steve Heuser (sheuser@ Nate Robson (nrobson@ and Daniella Cheslow (dcheslow@
