People with anxiety disorders may have a measurable chemical imbalance in the brain, according to new research. Scientists found that people with anxiety had lower levels of choline — a key nutrient that supports mood and memory. In a review of 25 studies, those with anxiety showed about 8% less choline overall, especially in the prefrontal cortex, the part of the brain that controls emotion, stress, and decision-making.
Choline helps build brain cell membranes and supports neurotransmitters that influence mood and focus. Researchers believe that long-term stress may cause the brain to use up choline faster, eventually lowering its levels. It’s not yet clear whether eating more choline-rich foods can reduce anxiety, but experts say this discovery could help guide future treatments and deepen understanding of how nutrition affects mental health.
Many people don’t get enough choline in their diet. Good food sources include eggs, salmon, beef, chicken, and soybeans. While supplements aren’t recommended for everyone, maintaining healthy choline levels may support brain function and emotional balance. Since anxiety affects nearly one in three adults worldwide, finding links between diet and brain chemistry could lead to new ways to prevent and manage it.
