New research has suggested that a high-fat diet could contribute to symptoms of anxiety and depression due to the unhealthy levels of blood sugar and excess body weight.
Research conducted the study on mice. The mice that were fed a diet that was high in fat underwent changes in the brain. The areas of the brain that underwent changes were associated with symptoms of anxiety. These symptoms were also able to cancel out the effects of anti-depressants due to the diet that the mice were consuming.
