Researchers at UC Davis Health found that people with anxiety disorders have about 8% lower levels of choline in their brains, especially in the prefrontal cortex, which controls thinking, emotions and behavior[1][2]. This nutrient is important for the proper function of the brain and the regulation of neurotransmitters that affect the processing of emotions and the response to stress[2]. Chronic activation of the stress response in anxiety can increase the consumption of choline, leading to its depletion and imbalance in the brain[1][2]. The study analyzed data from 370 people with anxiety disorders and 342 healthy subjects, confirming a consistent chemical pattern of low choline levels in patients with various forms of anxiety, including generalized anxiety, panic disorder, social anxiety and phobias[1]. Research suggests that choline deficiency may be a biological factor in anxiety and that a diet rich in this nutrient could help restore brain balance, although more research is needed[1][2]. Many people in the US do not achieve the recommended dietary intake of choline, making it a potential target for the prevention and treatment of anxiety disorders[1].
