“…Preparation of fermented Laminaria japonica (FLJ) by Lactobacillus brevis BJ20 and placebo FLJ was prepared according to our previous report (Reid et al, 2018). Briefly, L. japonica was added to water at a ratio of 1:15 (w/ v) with the addition of glucose and yeast based on L. japonica dry weight used.…”

A randomized, double-blind, and placebo-controlled clinical study was used to determine the cognitive functions related to working memory (WM) and antioxidant properties of fermented Laminaria japonica (FLJ) on healthy volunteers. Eighty participants were divided into a placebo group (n = 40) and FLJ group (n = 40) that received FLJ (1.5 g/day) for 6 weeks. Memory-related blood indices (brain-derived neurotrophic factor, BDNF; angiotensin-converting enzyme; human growth hormone, HGH; insulin-like growth factor-1, IGF-1) and antioxidant function-related indices (catalase, CAT; malondialdehyde, MDA; 8-oxo-2'-deoxyguanosine, 8-oxo-dG; thiobarbituric acid reactive substances, TBARS) were determined before and after the trial. In addition, standardized cognitive tests were conducted using the Cambridge Neuropsychological Test Automated Batteries. Furthermore, the Korean Wechsler Adult Intelligence Scale (K-WAIS)-IV, and the Korean version of the Montreal Cognitive Assessment (Mo-CA-K) were used to assess the pre and post intake changes on WM-related properties. According to the results, FLJ significantly increased the level of CAT, BDNF, HGH, and IGF-1. FLJ reduced the level of TBARS, MDA, and 8-oxo-dG in serum. Furthermore, FLJ improved physical activities related to cognitive functions such as K-WAIS-IV, MoCA-K, Paired Associates Learning, and Spatial Working Memory compared to the placebo group. Our results suggest that FLJ is a potential candidate to develop functional materials reflecting its capability to induce antioxidant mechanisms together with WM-related indices.

“…19 Five studies were also excluded because they used pro-/synbiotics in combination with other compounds only in the intervention group. [20][21][22][23][24] Finally, 10 RCTs with 12 treatment arms were included in this systematic review and metaanalysis. [9][10][11][25][26][27][28][29][30][31]…”

“…In contrast, supplementation with a plant extract of leaves of Eriobotrya japonica Lindley in apparently healthy subjects [35] and supplementation with nano-curcumin in subjects with metabolic syndrome [41] showed a trend to increased serum and plasma BDNF concentrations, respectively. Furthermore, supplementation with seaweed in apparently healthy subjects resulted in a significant increase in serum BDNF concentrations [36,37]. Supplementation with ellagic acid significantly increased plasma BDNF concentrations in overweight subjects but not in healthy subjects [40].…”

“…It can contribute to the development of atherosclerosis and its complications [36]. Insulin resistance and hyperglycaemia play an important role in the pathogenesis of endothelial dysfunction [37]. Next to glucose metabolism, insulin also exerts control on the endothelium where it stimulates the production of the vasodilator nitric oxide and vasoconstrictor endothelin-1 [38].…”

“…Therefore, the type of polyphenols studied was markedly different. One study examined 32 polyphenols from Eriobotrya japonica Lindley [35], two studies seaweed rich in polyphenols [36,37], two studies resveratrol [38,39], one study ellagic acid [40], two studies (nano-)curcumin [41,42], one study Ginkgo Biloba [43], one study green tea [44], and one study dark chocolate [45]. A combination of resveratrol and quercetin showed no effect on serum BDNF concentrations in overweight subjects [39].…”

Background: Brain-derived neurotrophic factor (BDNF) plays an essential role in brain and metabolic health. The fact that higher concentrations are associated with improved cognitive performance has resulted in numerous intervention trials that aim at elevating BDNF levels. This systematic review provides an overview of the relation between various nutritional factors and BDNF concentrations in controlled human intervention studies.Methods: A systematic search in May 2020 identified 48 articles that examined the effects of dietary patterns or foods (n = 3), diets based on energy intake (n = 7), vitamins and minerals (n = 7), polyphenols (n = 11), long-chain omega-3 polyunsaturated fatty acids (n = 5), probiotics (n = 8), and miscellaneous food supplements (n = 7).Results: In particular, studies with dietary patterns or foods showed increased peripheral BDNF concentrations. There are also strong indications that polyphenols tend to have a positive effect on BDNF concentrations. Four of the 11 included studies with a polyphenol intervention showed a significant increase in BDNF concentrations, one study showed an increase but this was not statistically analyzed, and two studies showed a trend to an increase. Conclusion:The two polyphenol classes, phenolic acids, and other phenolic compounds were responsible for the significant effects. No clear effect was found for the other dietary factors, which might also be related to whether serum or plasma was used for BDNF analysis. More work is needed to understand the relation between peripheral and central BDNF concentrations.
