Figure. Association of Mediterranean diet, fish, and meat with brain volume and cortical thickness.

(A) Mean levels (intracranial-adjusted residuals) of total brain volume (TBV), total gray matter volume (TGMV), and total white matter volume (TWMV) among participants with low (score 0–2), middle (score 3–5), and high (score 6–9) levels of adherence to the Mediterranean diet (MeDi), among tertiles of fish consumption (caloric intake adjusted residuals), and among tertiles of meat consumption (caloric intake adjusted residuals). (B) Mean cortical thickness by levels of MeDi, fish, and meat consumption.
