“…Similarly, this finding has been reflected in older adults. Esmaeilpour-Bandboni et al ( 13 ) found a reduction of depressive symptoms in an older population after a five-week green tea intervention (dose not specified). In addition, Calapai et al ( 14 ) showed a significant reduction in anxiety scores following a 12-week grape extract intervention in healthy older adults (250 mg capsule containing V. vinifera extract consisting of proanthocyanidins (>9% w/w) and anthocyanins (4%–5% w/w)/day).…”

IntroductionDuring the postpartum period, parents face psychological challenges and consequently, changes in mood and associated mood disorders have become increasingly prevalent in the 6-months following birth. Dietary flavonoids have been found to benefit mood and are therefore an appealing non-pharmacological option for potentially treating mood disorders in the postpartum. The aim of this study was to investigate whether a two-week dietary flavonoid intervention would improve mothers’ and fathers’ mental health in the immediate 6-month postpartum period.MethodThe study employed a randomised, parallel groups, controlled design to explore the effects of a flavonoid intervention vs. control group on several outcomes, including mood (PANAS), postpartum depression (EPDS), postpartum anxiety (PSAS-RSF-C) and quality of life (WHOQOL). Sixty participants (mothers n = 40, fathers n = 20) in the 6-month post-partum period were randomised to either a “flavonoid” or “control” condition. The flavonoid group were asked to add two flavonoid-rich foods (approximate flavonoid intake 218 mg/day) into their daily diet whilst controls (n = 23) were asked to continue with their usual diet for two-weeks (ClinicalTrials.gov (NCT04990622).ResultsSignificant effects were found in the flavonoid group where mothers reported higher positive affect and lower postpartum depression after the two-week intervention relative to baseline. This finding is especially relevant as a clinical reduction in postpartum depression scores in the flavonoid group by an average 2.6 scoring points was observed, which equated to a reduction from “possible depression” at baseline to “little or no depression” at 2-weeks, which was not observed in the control group. Fathers’ data was not analysed due to non-compliance with the intervention.DiscussionThis study provides evidence for the benefits of a dietary flavonoid intervention for mood and mental health in new mothers, supporting the utility of non-pharmacological, self—administrable changes to the diet for improving positive mood outcomes and reducing symptoms of postpartum depression in mothers during an especially challenging time. Further research for the effect of dietary interventions on paternal mental health is needed. Clinical Trial RegistrationClinicalTrials.gov, identifier NCT04990622.

“…The catechin can provide hydrogens from the hydroxyl groups in their structure; therefore, they possess an excellent ability to scavenge free radicals [3][4][5]. Catechin exhibited potential health benefits, such as lowering obesity, diabetes, and aging, as well as boosting the immune system [6,7]. Catechin found in tea leaf extract has been linked to a lower risk of cancer, stroke, and cardiovascular disease [8,9].…”

“…Furthermore, catechin has been used as functional food ingredients, providing users with a variety of health benefits such as cholesterol-lowering effects, brain aging prevention, and antioxidants. They were commonly found in cereals, ice cream, fried snacks, biscuits, and soft drinks [7,[10][11][12]. Catechins have been used in the pharmaceutical industry to prevent oxidants and bacteria in shower gel, cleanser, mouthwashes, and toothpaste [8,13].…”

Polyphenolic chemicals found in tea leaves are frequently used in pharmaceutics and the food industry. Catechin is a polyphenol that has antimicrobial, antioxidant, and antibacterial effects, as well as other health advantages. The goal of this study was to create a catechin-encapsulated alginate hydrogel (Cate-ALG) that would protect catechin from degradation and bioactivity loss in stressful environments while also delivering catechin. The antioxidant ability of catechin was found to be greater than that of vitamin C using the 2,2-diphenyl-1-pierylhyrazyl assay. The FT-IR spectra revealed the distinct peaks of catechin and alginate. Additionally, due to the hydrogen bond interaction between alginate and catechin molecules, frequency downshifting was observed in the carbonyl and hydroxyl regions. Furthermore, release profile revealed a burst release of 5% catechin-ALG in the first 25 min. On the other hand, the 3% Cate-ALG approached the controlled release profile of catechin and increased the release time by more than 40 minutes. The catechin in alginate hydrogel has the potential for controlled release via transdermal and wound dressing applications.
