significantly higher (b1⁄4 0.331, p1⁄40.03) but not in the top intake tertile (b1⁄4 0.116, p1⁄40.49). Compared with VAMP levels for individuals in the lowest tertile of total n-3 fatty acid intake, levels were higher only among individuals in the third but not the second tertiles of intake (for tertile 2, b1⁄4 0.228, p1⁄434; for tertile 3, b1⁄40.50, p1⁄4.04). Conclusions: This study suggests that one potential biological mechanism underlying the relation of long-chain n-3 fatty acids to brain health during aging is maintenance of neural reserve by sustaining higher levels of presynaptic proteins, vital to neural signaling.
