The global market of functional foods targeting wellness promotion, disease risk reduction, and quality of life promotion has been increasing. Due to this demand, the development of novel functional ingredients is essential when producing new fortified foods and beverages. The aim of this study was to determine the effect of the eight-week consumption of a functional soup containing “Anthaplex” [a novel functional ingredient consisting of the extracts of purple waxy corn (Zea mays) and coloured sticky rice (Oryza sativa)] on cognitive function and eye dryness in healthy volunteers in late adulthood. This study was an 8-week, 3-arm, randomised, double-blind, placebo-controlled study. A total of 69 participants were randomly assigned to placebo, D2 (2g of Anthaplex), or D4 (4g of Anthaplex) treatment group. Results showed that “Anthaplex” can improve cognitive function and working memory together with eye dryness. Authors concluded that “Anthaplex” could be a new functional ingredient for supplements aiming to improve cognitive function and eye dryness.
Abstract
Due to the rising demand for supplements targeting cognitive enhancement and dry eye together with the health benefits of anthocyanins, we have developed a functional soup containing an anthocyanin-rich functional ingredient, or "Anthaplex," and assessed the effects on cognitive function and eye dryness together with the possible mechanisms. A total of 69 male and female health volunteers were randomized and divided into placebo, D2, and D4 groups. All subjects consumed 120 mL of placebo or functional soup containing "Anthaplex" either at 2 or 4 g per serving per day within 5 min in the morning for eight weeks. The cognitive function, working memory, dry eye, AChE, MAO, MAO-A, MAO-B, and GABA-T activities, BDNF, HAC, HDAC, and DNMT activities, pH, and amount of lactic acid-producing bacteria, particularly Lactobacillus and Bifidobacterium spp. in feces, were determined before intervention and after eight weeks of consumption. Subjects who consumed the "Anthaplex" soup had improved cognitive function, working memory, eye dryness, histone acetylation, ACh E suppression, and BDNF with increased Bifidobacterium spp. but decreased pH in feces. These data suggest that "Anthaplex" improves cognitive function and eye dryness via the modulations of the histone acetylation process, gut microbiome, and cholinergic function.

Plain language summary
High-intensity aerobic training has been shown to suppress leukocyte counts in moderately fit athletes. The aim of this study to explore possible advantageous effects of cashew apple juice (CAJ) supplementation, and, if present, to identify the possible mechanisms underlying those effects. The study is a double-blind randomised cross-over design with two treatment arms: CAJ supplementation and placebo. Ten moderately (endurance) trained and untrained men were randomized to one of the two groups for four weeks, with a four-week wash out period. Results showed that CAJ supplementation for four weeks increased leukocyte (a type of blood cell) counts, while simultaneously decreasing oxidative stress, following an acute bout of high-intensity exercise in trained men. Furthermore, the CAJ supplementation increased neutrophil (a type of white blood cell) counts while simultaneously reducing oxidative stress and stress hormone concentrations in untrained men. The antioxidant effects following exercise were observed in both endurance-trained and untrained men. Authors conclude that CAJ supplementation is beneficial to men, both in resting states and in response to an acute bout of high-intensity aerobic exercise.
Abstract
BACKGROUND Cashew apple juice (CAJ) was shown to improve immunological mechanisms by regulating a balance between reactive oxygen species and antioxidant concentrations. However, no study exploring the effects of the CAJ and training status on the immune system and oxidative stress induced by exercise. Therefore, we investigated the effects of CAJ supplementation primarily on leukocyte counts and secondary on oxidative stress and cortisol changes after high-intensity exercise in trained and untrained men. METHODS Ten moderately (endurance) trained (Age = 21.5 ± 0.97 yr., VO2max = 45.6 ± 4.12 mL/kgBM/min) and ten sedentary men (Age = 20.4 ± 2.72 yr., VO2peak = 32.2 ± 7.26 mL/kgBM/min) were randomized to ingest either daily CAJ or a placebo at 3.5 mL/kgBM/day for 4 weeks, with a four-week washout period. Before and after each period, they performed 20-min, high-intensity cycling (85% VO2max), with blood samples collected immediately preceding and the following exercise. Samples were analyzed to determine leukocyte counts, malondialdehyde, 8-isoprostane, and cortisol concentrations. A repeated measures analysis of variance was used to examine the effects of supplement and training status over time with an alpha level of 0.05. RESULTS There was no interaction between supplement and training status on those variables before and after exercise. However, CAJ raised resting neutrophil counts and exercise-induced leukocyte counts in the trained group (all p < 0.05). Besides, CAJ significantly reduced plasma malondialdehyde concentrations at rest and after exercise and reduced the post-exercise plasma 8-isoprostane concentration in both groups of subjects (p < 0.05). Moreover, CAJ reduced plasma cortisol after exercise in the untrained subjects. CONCLUSIONS We suggest that 4-week CAJ supplementation can enhance exercise-induced leukocyte and resting neutrophil counts in trained men. The possible mechanism is a reduction in oxidative stress. However, the supplementation did not change the immune responses of untrained men, but it did reduce stress hormone concentrations.

Abstract
Based on the benefit of polyphenolic compounds on osteoporosis, we hypothesized that the polyphenol-rich herbal congee containing the combined extract of Morus alba and Polygonum odoratum leaves should improve bone turnover markers in menopausal women. To test this hypothesis, a randomized double-blind placebo-controlled study was performed. A total of 45 menopausal participants were recruited in this study. They were randomly divided into placebo, D1, and D2 groups, respectively. The subjects in D1 and D2 groups must consume the congee containing the combined extract of M. alba and P. odoratum leaves at doses of 50 and 1500 mg/day, respectively. At the end of an 8-week consumption period, all subjects were determined serum bone markers including calcium, alkaline phosphatase, osteocalcin, and beta CTX. In addition, the hematological and blood clinical chemistry changes, and total phenolic content in the serum were also determined. The results showed that the menopausal women in D2 group increased serum alkaline phosphatase, osteocalcin, and total phenolic compounds content but decreased CTX level. Clinical safety assessment failed to show toxicity and adverse effects. Therefore, herbal congee containing the combined extract of M. alba and P. odoratum leaves is the potential functional food that can decrease the risk of osteoporosis.

Abstract
OBJECTIVE Based on the crucial role of oxidative stress on physical performance and muscular strength, we aimed to determine the effect of a 12 week-consumption period of cashew apple juice, a substance possessing antioxidant effect, on the physical fitness and oxidative stress status of the middle aged and the elderly. MATERIAL AND METHOD A randomized double-blind placebo-controlled design was performed. Forty-five healthy middle-age and elderly volunteers received 1,000 ml of either cashew apple juice (120 and 240 mg/day) or placebo once daily for 12 weeks. The changes of malondialdehyde (MDA) level and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) enzymes in the plasma together with the health related-physical fitness was assessed every four weeks throughout the 12-week consumption period and four weeks after the cessation of the consumption. RESULTS The subjects who consumed the cashew apple juice at dose of 240 mg/day showed improved oxidative stress status and enhanced performance in 30-second chair stand test and 6-minute walk test. These data suggested that a 12-week consumption period of cashew apple juice consumption enhance muscle strength of lower extremities and the cardiopulmonary endurance. CONCLUSION The possible underlying mechanism might occur partly via the improved oxidative stress status. Therefore, cashew apple fruit juice may be a potential candidate to enhance the health-related physical fitness for the middle aged and elderly volunteers. However, further research is required to provide better understanding about the precise underlying mechanism.

Abstract
[Purpose] We aimed to evaluate the effects of Phyllanthus amarus (PA) on oxidative stress and damage, inflammation, and soreness in muscle after a single session of moderate-intensity exercise. [Subjects and Methods] Twelve men randomly participated in 2, three-day phases with a one-week washout period. On the first day, participants consumed two capsules of PA or placebo control (CTL) before 20 min of cycling. They then consumed four capsules on the same day after exercise and six capsules/day for the next two days. Blood samples were obtained before, immediately after exercise and 24 h and 48 h after exercise. The pain tolerance was measured at both legs. [Results] Plasma vitamin C levels in the PA group were higher than those in the CTL group after exercise. At 48 h after exercise, vitamin C levels were higher in the PA group, but those in the CTL group were lower than the pre-exercise levels. However, plasma levels of creatine kinase were increased in both groups after exercise compared with the pre-exercise levels. The neutrophil count was higher immediately after exercise than the pre-exercise levels in the CTL group. [Conclusion] Acute supplementation with PA improves antioxidant status after a single session of moderate-intensity exercise.
