“…These inconsistent results could be due to the differences in study population, patterns of food consumption, and the heterogeneity in the instruments used to assess cognitive function (31) . It should be mention that the STICs-m is a screening questionnaire and not a diagnostic one, and it is mainly focused on determine the verbal episodic memory.…”

Polyphenol intake and cognitive decline in the Seguimiento Universidad de Navarra (SUN) Project

The global growing rates of cognitive decline and dementia, together with the absence of curative therapies for these conditions, support the interest in researching potential primary prevention interventions, with particular focus on dietary habits. The aim was to assess the association between the intake of polyphenols and 6-year change in cognitive function in the “Seguimiento Universidad de Navarra” (SUN) Project, a Spanish prospective cohort study. Changes (final – initial) in cognitive function were evaluated in a subsample of 806 participants (mean age 66 years (SD 5), 69.7% male) of the SUN Project using the validated Spanish Telephone Interview for Cognitive Status-modified (STICS-m) score. Polyphenol intake was derived from a validated semi-quantitative food-frequency questionnaire and matching food composition data from the Phenol Explorer database. Multivariable linear regression models were used to evaluate the association between total polyphenol intake, polyphenol subclasses and cognitive changes. No significant association between total polyphenol intake and changes in cognitive function was found. However, a higher intake of lignans (βQuintile (Q) 5 vs. Q1 0.81; 95% CI 0.12, 1.51; p trend = 0.020) and stilbenes (βQ5 vs. Q1 0.82; 95% CI 0.15, 1.49; p trend 0.028) was associated with more favorable changes in cognitive function over time, particularly with respect to immediate memory and language domains. Olive oil and nuts were the major sources of variability in lignan intake; and wine in stilbene intake. The results suggest that lignan and stilbene intake was associated with improvements in cognitive function.

“…Fruits and vegetables are the source of phytochemicals and major contributors of dietary polyphenols that provide protective mechanism such as antioxidant and anti-inflammatory for human (Hervert-Hernández et al 2011;Slavin & Lloyd 2012). Polyphenol consumption also shows beneficial effects on cognitive and mental health status especially among elderly (Rosli et al 2014).…”

The aim of this study was to determine the polyphenol content and antioxidant activities in commercialized date and pomegranate concentrates that are available in local market. A total of seven samples comprised of two brands of date concentrates (D1 and D2) and five brands of pomegranate concentrates (P1, P2, P3, P4, and P5) have been analyzed for their polyphenol content and antioxidant activity. The Folin-Ciocalteu assay was used to determine the polyphenol content (TPC) of the samples while 2,2-diphenyl-1-picrylhydrazyl-hydrate (DPPH) and Ferric Reducing Antioxidant Power (FRAP) assays were used to determine the antioxidant activity. The results showed the commercialized date concentrate D2 contained the highest TPC (1243.00 ± 67.00 mg GAE/100 ml) and antioxidant activity using FRAP assay (2.67 ± 0.01 mmol TE/100 ml). Date concentrate D1 showed the highest antioxidant activity using DPPH assay (0.39 ± 0.02 mmol TE/100 ml). The pomegranate concentrate P5 showed the highest reading for TPC (3260.10 ± 428.70 mg GAE/100 ml), DPPH (1.61 ± 0.05 mmol TE/100 ml) and FRAP assays (20.98 ± 0.42 mmol TE/100 ml). As a conclusion, the studied commercial date and pomegranate concentrates available in the local market contained high polyphenol and antioxidant contents although the content levels were different from one brand to another. Further study is needed to identify the causes of this distinction. The results of this study could help the consumers to make a better selection of commercialized date and pomegranate concentrates that are available in local market in term of polyphenol content and antioxidant activity.

It has also been reported to be rich in polyphenols (Su & Arab 2006) that may be beneficial in improving cognitive status (Rosli et al 2014). Medicinal plants such as herbs and ulam are therapeutic agents which have been used in many cultures but studies regarding the development of ulam as fortified food products are still limited.…”

Ulam is the South East Asian traditional vegetables which contains high total phenolic content and exhibits antioxidant activity. Several studies have reported the potential of neuroprotective effect of ulam. The objective of this review article was to highlight the total phenolic content (TPC) and antioxidant activity of ulam and the roles of phenolic content that can contribute to attenuation of cognitive decline. The review includes randomized controlled trial and experimental studies from year 2007 to 2017. In this review, PRISMA method was used to report the results (n=15). Phenolic compounds, ie plants' second metabolites of selected ulam in South East Asia were also discussed in this review, with respect to its potential for health promotion which and reducing the risk of cognitive disease. Oenanthe javanica (selom), Ocimum basilicum (daun selasih) and Anacardium occidentale L. (pucuk gajus) were ranked in the top three highest TPC among all the selected ulam. In general, Polygonum minus (kesum), Anacardium occidentale L. (pucuk gajus) and Cosmos caudatus (ulam raja) exhibited high DPPH radical scavenging activity whereas Anacardium occidentale L. (pucuk gajus) exhibited highest ferric ion reducing potential (FRAP) among all the selected ulam in South East Asia countries. Overall, some studies had shown Centella asiatica (pegaga), Oenanthe javanica (selom), Polygonum minus (kesum), Ocimum basilicum (daun selasih) and Murraya koenigii (daun kari) are beneficial in improving cognitive status and mood. The bioactive compounds in ulam may exhibit neuroprotective effects but human studies are still lacking in exploring the relationship between ulam consumption and cognitive status.
