Summary:Limited research suggests mushroom consumption may improve indexes of brain health. Mushrooms contain bioactive compounds and antioxidants capable of crossing the blood–brain barrier and impacting vital neurological processes. We conducted a randomized controlled feeding trial assessing the effects of adopting a healthy U.S. Mediterranean-style dietary pattern (MED) with or without mushrooms on indexes of brain health and well-being. Sixty adults (aged 46 ± 12 y; BMI 28.3 ± 2.84 kg/m2; mean ± SD) without severe depression consumed a fully controlled MED diet with 84 g/d of mushrooms (4 d/week white button and 3 d/week oyster) or without (control with breadcrumbs) for 8 weeks. At baseline and post-intervention, surveys were used to evaluate anxiety, depression, mood, and well-being, and behavioral tests were used to evaluate cognition. Consumption of the MED diet, with or without mushrooms, increased (improved) self-reported vigor/activity (Time p = 0.026) and both behavioral measures of immediate memory (Time p < 0.05). Mixed effects were observed for other domains of neuropsychological function, and there were no changes in other measured indexes of brain health with the consumption of either MED diet. Adopting a healthy MED-style dietary pattern, with or without consuming white button and oyster mushrooms, may improve vigor/activity and immediate memory among middle-aged and older adults.
