Using a non-invasive MRI-based technique that measures brain chemicals, researchers at UC Davis Health in California looked at data from 25 previous studies, comparing 370 people with anxiety disorders to 342 without anxiety.\u00a0<\/p>\n
They found that, across the combined studies, individuals with certain anxiety disorders showed an average of about 8% lower choline levels in brain regions that help regulate thinking and emotions.\u00a0<\/p>\n

(iStock)<\/p>\n The study authors propose that heightened stress responses in anxiety disorders may increase the brain’s demand for choline, gradually lowering levels of the nutrient \u2014 especially in regions that help regulate stress and reduce the threat response, according to the published research.<\/p>\n The findings don’t prove that low choline causes anxiety. The researchers also emphasized that it’s too early to recommend eating more choline or taking large doses of it in supplement form.<\/a>\u00a0<\/p>\n BRAIN AGING MAY SLOW WITH GREEN TEA, WALNUTS AND TINY SWAMP PLANT, STUDY FINDS<\/a><\/p>\n The research does, however, reveal a pattern across three major anxiety disorders that could shape future research into how nutrition and brain chemistry interact with anxiety disorders, they said.<\/p>\n “It suggests nutritional approaches \u2014 like appropriate choline supplementation \u2014 may help restore brain chemistry and improve outcomes for patients,” study co-author Jason Smucny said in a statement.<\/p>\n Anxiety disorders affect nearly 30% of U.S. adults, according to experts. (iStock)<\/p>\n But several clinicians and nutrition experts told Fox News Digital the results should be interpreted cautiously and warned Americans against assuming anxiety is caused by a nutrient deficiency.<\/p>\n Maddock said more research is needed to learn if increasing choline will reduce anxiety. He warned that heavy choline supplements can cause side effects.<\/p>\n Experts note that people may benefit from reviewing their choline intake as part of routine nutritional guidance and recommend discussing any changes \u2014 especially for those with anxiety \u2014 with a healthcare provider.<\/p>\n YOU MAY BE EATING KALE ALL WRONG AND MISSING OUT ON KEY NUTRIENTS, RESEARCHERS WARN<\/a><\/p>\n Choline is considered “essential” because the body makes only a small amount of it, and the rest has to come from food, research has shown. Studies have found<\/a> that most Americans, including children, don’t get the recommended daily amount of the nutrient.<\/p>\n Some omega-3 fats found in fish, such as salmon,<\/a> may be “especially good” at delivering choline to the brain, Maddock noted.<\/p>\n Experts say a balanced, choline-rich diet may support brain health but is not a replacement for anxiety treatment. (iStock)<\/p>\n “Anxiety disorders are the most common mental illness<\/a> in the United States, affecting about 30% of adults,” Maddock said.\u00a0<\/p>\n “They can be debilitating for people, and many people do not receive adequate treatment.”<\/p>\n TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZ<\/a><\/p>\n Nona Kocher, a board-certified psychiatrist in Miami Beach, agreed that an 8% drop is not “trivial.”\u00a0<\/p>\n Kocher, who was not involved in the study, described the pattern as potentially indicating stress on metabolic processes.<\/p>\n “One big misunderstanding is thinking that a nutrient deficiency is the main cause of anxiety.”\u00a0<\/p>\n “We know from the clinic that this kind of burden is associated with feeling easily overwhelmed, feeling less resilient under stress and being mentally tired earlier in the day,” she told Fox News Digital.<\/p>\n Nonetheless, the data suggest a consequence more than a cause, she noted.<\/p>\n CLICK HERE TO SIGN UP FOR OUR LIFESTYLE NEWSLETTER<\/a><\/p>\n The researchers emphasized that the new findings do not mean choline is the cause of anxiety \u2014 or that people should ditch treatment plans in favor of diet tweaks.<\/a> The MRI technique they used captures chemical stress signals in the brain, so low choline may reflect metabolic strain and not simply a nutrient deficiency.<\/p>\n “One big misunderstanding is thinking that a nutrient deficiency is the main cause of anxiety,” said Lauren Manaker, a registered dietitian nutritionist in South Carolina.\u00a0<\/p>\n Researchers say lower choline levels in brain regions are responsible for emotion regulation and stress response. (iStock)<\/p>\n “Anxiety is complicated and usually involves a mix of factors, like genetics, life experiences and brain chemistry,” Manaker, who was not involved in the research, told Fox News Digital.\u00a0<\/p>\n “While low choline might have an association, it’s not the whole story.”\u00a0<\/p>\n CLICK HERE FOR MORE LIFESTYLE STORIES<\/a><\/p>\n Mood and anxiety disorders have been tied to other nutrient deficiencies, including vitamin D, Manaker said.\u00a0<\/p>\n A balanced diet that includes foods like dairy milk and eggs \u2014 which provide choline, vitamin D, B12 and other brain-supporting nutrients \u2014 may help address those gaps, but nutrition is only one piece<\/a> of managing anxiety, she emphasized.<\/p>\n Experts caution that more research is needed before recommending choline supplementation. (iStock)<\/p>\n Kocher agreed choline is just “one of many pieces of a larger stress biology puzzle, not the sole driver.”<\/p>\n Manaker said a choline-rich diet is important for overall brain health,<\/a> regardless of whether someone has anxiety.<\/p>\n![\"Woman's](\"https:\/\/a57.foxnews.com\/static.foxnews.com\/foxnews.com\/content\/uploads\/2025\/12\/1200\/675\/fried-eggs-choline-anxiety-nutrient.jpg?ve=1&tl=1\")
