Diet and mental health: Review of the recent updates on molecular mechanisms

Since few human studies had explored the brain structures potentially affected by long-term diet quality, Akbaraly et al. (2018) tested whether there is an association between cumulative average Alternative Healthy Eating Index 2010 (AHEI-2010) score during adult life, with hippocampal volume. The researchers gathered data on the 459 participants of the Whitehall II imaging sub-study […]

Since microglia in the hippocampus are vulnerable to the effects of ageing, Spencer et al. (2019) assesses if the morphological and functional changes in microglia explain the findings from their previous studies showing short-term high-fat diets (HFD) significantly impairing hippocampal- and amygdala- based cognitive function only in the ageing and not in the young rats.
