According to a recent analysis of UK Biobank data, people who frequently consume raw vegetables tend to have a higher total volume of brain white matter. Strangely, those with a higher intake of fresh fruit generally have a lower total volume of grey matter. However, they exhibit larger grey matter volumes in brain areas associated with dementia and depression. These findings were published in NeuroImage, and they suggest that regular consumption of fresh fruits and raw vegetables may have a positive impact on brain structure.
A recent meta-analysis has indicated that a high consumption of fruits and vegetables is linked with a lower risk of depression. Another study reported an association between high consumption of fruits and vegetables and a reduced risk of cognitive impairment and dementia. Despite these findings, the physiological mechanisms underlying these associations remain unclear.
