Authors: Detzel Christopher , Petschow Bryon W. , Johnson Nicole , Weaver Eric M. 
Published: August 2018

Background: Increasing dietary protein intake synergistically improves the effect of exercise to stimulate muscle protein synthesis. The purpose of this study was to evaluate the plasma amino acid response of two novel protein nutritional preparations, beef protein isolate (BeefISOTM) and hydrolyzed chicken protein isolate (MyoCHXTM). Methods: The postprandial plasma amino acid response over 3 hours was monitored in young adults (n=6) following consumption of 23 grams of WPC, BeefISOTM, or MyoCHXTM. Amino acid compositional analysis and molecular weight distributions of each protein were performed by HPLC. Statistical analyses were performed using one-way or two-way ANOVA where appropriate and corrected for multiple comparisons to account for the cross-over design. Results: Compositional evaluations revealed similar levels of essential and branched-chain amino acids for WPC and MyoCHXTM. While the results of this study predictably demonstrated plasma amino acids levels increased following consumption of the different proteins, the kinetics of the postprandial response was unique to each protein source. WPC and MyoCHXTM were rapidly absorbed with maximum plasma amino acid concentrations observed at 30 and 15 min, respectively. The slightly faster absorption of MyoCHXTM was associated with the increased peptide content of MyoCHXTM (greater than 76% of protein is <2kDa). BeefISOTM exhibited sustained release characteristics as evidenced by increased post prandial amino acid concentrations after 3 hours. Conclusions: The protein preparations studied each had different amino acid profiles and absorption kinetics. WPC and MyoCHXTM contained a higher essential amino acid content and were rapidly absorbed with plasma amino acid concentrations peaking within 30 minutes following consumption. BeefISOTM contained a higher proportion of conditionally essential amino acids that steadily increased in plasma over 3 hours, indicating a sustained release profile for BeefISOTM. Each of these three protein preparations have been shown to facilitate similar improvements in body composition following a resistance-exercise training program. The paradoxical finding that proteins with varying composition, molecular weight, and digestibility can lead to similar effects on body composition suggests the need to evaluate proteins based on total nutritional potential rather than as a delivery vehicle for single amino acids.Key Words: Protein digestibility; amino acids; body composition; beef protein; chicken protein

Published: August 2018

Background: Numerous in vitro and in vivo studies, in addition to clinical data, demonstrate that pomegranate juice can prevent or slow-down the progression of some types of cancers. Despite the well-documented effect of pomegranate ingredients on neoplastic changes, the molecular mechanism(s) underlying this phenomenon remains elusive.Methods: For the study of pomegranate ingredients the electron-ion interaction potential (EIIP) and the average quasi valence number (AQVN) were used. These molecular descriptors can be used to describe the long-range intermolecular interactions in biological systems and can identify substances with strong electron-acceptor properties. In this study, candidate human proteins interacting with pomegranate flavonoids have been analyzed by the informational spectrum method (ISM). This represents a virtual spectroscopy method for studying protein molecular interactions.Results: Our analysis indicates that the anti-cancer properties of pomegranate juice can be ascribed to the strong electron-acceptor properties of its chemical ingredients. This analysis also suggests that pomegranate flavonoids inhibit the “NF-kappaB” (NF-kB) pathway, which plays a critical role in the pathogenesis of cancer.Conclusion: The results offer a possible explanation for an important molecular mechanism underlying the anticancer activity of pomegranate ingredients, which could also serve as a basis for the development of new therapeutic compositions of food supplements with pomegranate-like anticancer properties.Key words: cancer, pomegranate, flavonoids, food supplement, informational spectrum method

Background: Maternal nutritional status can have an impact on numerous early developmental processes, and in certain cases these effects can influence the risk her offspring have for select chronic diseases later in life. We report on the effects of maternal consumption of high levels of certain flavonoids on the development of coronary artery disease (CAD) in an atherosclerosis-prone mutant mouse model.Methods: LDLr -/- mutant mice were fed a control fat (CF), high fat (HF), or the HF diet supplemented with epicatechin and catechin (HFEC) or rutin (HFRU), prior to pregnancy and during lactation to explore whether the flavonoids influenced markers of vascular health in the lactating dams (lactation day (LD) 21). Post-weaning (postnatal day (PND) 22), offspring were challenged with an atherogenic environment (HF diet in the absence of flavonoids) and vascular health markers were assessed in the adult offspring (PND 60).Results: Dams fed the HF diet had elevated markers of atherosclerosis on LD 21 compared to dams fed the control diet. Flavonoid consumption prior to pregnancy and during lactation had inconsistent effects on maternal markers of atherosclerosis (plasma cholesterol, aortic lipid accumulation, and oxidative stress biomarkers) at LD 21 compared to dams fed the HF diet without flavonoids. At PND 60, there were no differences in vascular health markers among the groups of LDLr -/- offspring whose mothers consumed the CF or the HF diet with or without flavonoids during lactation.Conclusions: Maternal consumption of the flavonoid-supplemented HF diets had modest effects on maternal markers of atherosclerosis. Offspring exposure of the flavonoid-supplemented HF diets during early lactation had little effect on the cardiovascular parameters assessed in the adult offspring.

Authors: McAnany Brian , Martirosyan Danik 
Published: August 2018

Prevalence rates of Alzheimer’s disease are increasing in countries around world, and identifying effective treatments to manage cognitive impairment and neurodegeneration has become a global health priority. Decades of scientific research have developed a more comprehensive understanding of the Alzheimer’s Disease and Mild Cognitive Impairment (MCI), a transitional stage of accelerated cognitive decline. This understanding has allowed researchers to envision novel Alzheimer’s Disease therapies, including the use of bioactive compounds found in plants and animals. Within the past 15 years, a significant amount of clinical research has been published documenting the effects specific bioactive compounds have on patients with Alzheimer’s Disease and MCI. This article reviews the results of this research, and discusses whether sufficient evidence exists to support the use of specific bioactive compounds by individuals diagnosed with Alzheimer’s Disease and MCI. Information on relevant epidemiological studies, outcome measures, and disease pathologies is provided to enrich this discussion.

Published: August 2018

Fusobacterium nucleatum (ATCC 25586) is an obligate anaerob, gram negative, non-spore former, and pleomorphic bacillus that can cause brain, pleura, lung and liver diseases mainly in the mouth and teeth. It was also noted that F. nucleatum induces fetal death (fetal demise) in pregnant women. Recent studies implicated that F. nucleatum could lead to colon cancer by binding the epithelial tissue. Kefir is originally produced from kefir grains that are actually a mine of probiotics. Fermented dairy products especially kefir and yogurt are significant for functional nutrition. Lactic acid bacteria, acetic acid bacteria and yeasts are embedded in a polysaccharide matrix, called kefiran, in kefir grains. When kefir grains are added to milk and incubated for approximately 22 h at 25°C, microorganisms in the grains continue to proliferate in milk with the production of the functional metabolic compounds. While yogurt has mainly two bacteria, authentic kefir has its characteristic Lactobacillus kefiranofaciens, Lactobacillus kefir and Lactobacillus parakefir in addition to many other types of LAB. Previous studies have indicated that fermented dairy products can cause probiotic effects such as improvement in digestive system health, serum cholesterol reduction, and improvement in lactose tolerance, improved immune function, control of irritable bowel symptoms, as well as anticarcinogenic properties.The aim of this research is to study in vitro the growth of F. nucleatum with fermented dairy products known to have a positive effect on intestinal health and so to investigate the possible inhibition effect of dairy products on this microorganism that is directly related to intestinal cancer. The effect of microflora and metabolites of kefir, yogurt and milk samples against to F. nucleatum were determined with various methods (microflora formation after fermentation, zone inhibition). Kefir samples exhibited distinct inhibitory zone against F. nucleatum after incubation agar plates. In addition, both probiotic bacteria and related pathogen were enumerated after fermentation by adding a certain amount of F. nucleatum pure culture to kefir and yoghurt samples. It was found that number of F. nucleatum decreased depending on kefir and yoghurt concentration produced from kefir grains.Kefir is known to have positive effects on health, especially intestinal health; therefore, these findings are important since inhibition effect of fermented dairy products against a pathogen and possible carcinogen was shown. Regular consumption of natural fermented dairy products especially kefir should be included in a functional diet. It could be promising to investigate with in vivo studies.

Published: August 2018

Background: The prevalence of diabetes has increased dramatically in recent decades in the regions where people excessively consume white rice. In spite of the higher nutritional values and bioactive components, only the low to medium glycaemic index (GI) brown rice could be of interests as an alternative to white rice in these regions. Methods: Five varieties, Chiang (CH), Sungyod (SY), Lepnok (LP) from Thailand and Long grain specialty 1 (LS1) and Long grain specialty 2 (LS2) from Malaysia were tested for GI. Ten test foods were prepared from 5 varieties by 2 cooking techniques (pressure cooker, PC and rice cooker, RC). Overnight fasted healthy subjects were fed with 25 g glucose as a reference food (RF) on 3 occasions and amount equivalent to 25 g available carbohydrate portion of test food (TF) on 1 occasion in separate days. Fasting and post-prandial capillary blood glucose was measured via finger-prick methods at 0, 15, 30, 45, 60, 90 and 120 min, and the incremental area under curve (iAUC) was determined. The GI of each TF was calculated as percentage of incremental area under curve (iAUC) of TF over RF.Results: The mean GI values of SY (72 – 81, high), CH and LP (59 – 65, medium) and LS1 and LS2 (64 – 73, medium to high) were found due to cooking by PC and RC methods. The GI did not vary significantly (p>0.05) among varieties as well as between cooking methods. GI showed a significant negative correlation with the amylose content (r = –0.70, p<0.05) and significant positive correlation with cold peak viscosity (r = 0.80, p<0.01).Conclusions: All five varieties by either cooking methods are classified as medium to high GI. Medium GI varieties could have potential of being used in diabetic diet. Cooking methods did not significantly alter the glycaemic characteristics of the studied varieties. Amylose content and pasting properties can be used for predicting GI of brown rice. It is urgent to explore low GI brown rice varieties in these regions.
Lactobacillus gasseri SBT2055 Stimulates Immunoglobulin Production and Innate Immunity after Influenza Vaccination in Healthy Adult Volunteers: a Randomized, Double-blind, Placebo-controlled, Parallel-group Study

Published: August 2018

Background: Lactobacillus gasseri strain SBT2055 (LG2055) is a human intestine-originating probiotic bacterium and potent probiotic known to exert various health promotion effects, including prevention of abdominal adiposity in rats and humans. A recent finding in mice has suggested that oral administration of LG2055 induces a protective effect against influenza A virus infection. In this context, evidence for efficacy of LG2055 using a human clinical trial was imminently required.Methods: To confirm this in humans, a randomized, double-blind, placebo-controlled, parallel-group study in healthy adult volunteers was conducted to examine the effect of drinkable yogurt (DY) containing LG2055 on influenza vaccine-specific antibody responses as the primary objective and innate immune responses as the secondary objective. Subjects were asked to consume 100 g/day of DY with LG2055 (LG2055 group; n = 94) or without LG2055 (placebo group; n = 94) for 16 weeks. After 4 weeks, all subjects received a trivalent influenza vaccine. Results: We found that the intake of LG2055 DY increased hemagglutination inhibition titers against influenza viruses A/H1N1 and B and the rate of seroprotection against influenza B after vaccination as compared with the intake of placebo DY by healthy volunteers. In support of this result, we confirmed that total IgG and IgA levels in plasma and sIgA production in saliva were also higher in the LG2055 group than in the placebo group. Furthermore, the intake of LG2055 DY enhanced natural killer cell activity and myxovirus resistance A gene expression, which is one of the antiviral genes stimulated by type I or type III Interferons in peripheral blood mononuclear cells.Conclusions: These results strongly indicate that LG2055 activates both the innate and adaptive human immune responses, suggesting the potential to prevent influenza virus infections by providing specific probiotics as complementary foods.Keywords: human clinical trial, innate immunity, influenza virus, Lactobacillus gasseri, vaccine

Published: August 2018

Background: Diabesity refers to the complicated conditions of diabetes and obesity occurring simultaneously within a single individual. The incidences of diabetes and obesity are growing at a rapid pace throughout the world that are mainly associated with lifestyle and dietary habits, aside from genetic vulnerability. Authors have reviewed the epidemiology and other negative aspects of diabesity followed by some of the management practices recommended. The declining of traditional lifestyles and dietary patterns is leading to a rapid increase in the prevalence of diabesity that is upcoming as a serious cause of concern world over. Diabetes, obesity, and their associated complications are without doubt a principal issue and threat in developing and under-developed nations. Diabesity has emerged as a major threat. This condition has been described as a slow poison, whose influence cannot be controlled or cured. The dietary measures offer the most viable and effective solution to diabetes onset, in addition to the obese state. The designing of a smart diet (i.e. healthy diet) and selecting gut microbiota having probiotic influence on the host can target in the weight reduction/ management, in addition to stabilizing sugar levels in the blood of an individual. Additionally, the regular physical workout can help an individual in controlling body weight and regulate other biochemical conditions which lead to various types of metabolic disorders. All of these issues are discussed in this review article which covers the causes, prevention, and control of diabesity.Keywords: Diabetes; obesity; diabesity; gut microbiota; probiotics
Dietary interventions as a neuroprotective therapy for the delay of the onset of cognitive decline in older adults: Evaluation of the evidence
Authors: Krause Debra , Roupas Peter 
Published: August 2018

Background: The relationship between nutrition and cognitive functioning is unclear, especially in elderly populations as many elderly people with cognitive impairment have low blood levels of some nutrients even in the absence of malnourishment. The objective of this review was to assess the evidence from systematic reviews of human studies on the effectiveness of dietary interventions as monotherapies in delaying the onset of cognitive decline in older adults.Scope and approach: Evidence-based methodologies were used to gather and assess the highest levels of evidence that evaluated the effects of administration of any dose of the individual dietary interventions as neuroprotective agents for any duration. The search strategy was designed to identify systematic reviews and meta-analyses published from 1990 to December 2015. There were no language restrictions as part of the inclusion criteria.Key Findings and Conclusions: This review provides the current state of knowledge from systematic reviews on the effects on cognition of acetyl-L-carnitine, alpha-lipoic acid, choline, inositol compounds, omega-3 polyunsaturated fatty acids, and polyphenols, which are all commonly studied nutrients for neurocognitive effects. A critical evaluation of the current evidence from systematic reviews indicated that there are no clinically-relevant effects from supplementation with these nutrients on delaying the onset of cognitive decline in older adults.

Published: August 2018

Background: Commercial conjugated linoleic acid (CLA) dietary supplements of contain an equal mixture of the C18:2 isomers, cis-9,trans-11 and trans-10,cis-12. CLA-c9t11 occurs naturally in meat and dairy products as the dominant CLA at 75%, whereas the CLA-t10c12 occurs at <1%. CLA-c9t11 generally promotes lipid accumulation but CLA-t10c12 inhibits lipid accumulation and may promote inflammation.Methods: Purified CLA-c9t11 and CLA-t10c12 were added to 3T3 mature adipocyte cultures at 100uM concentrations and compared with 100uM C18:3(n-3) (α-linolenic acid) and 50uM docosahexaenoic acid (DHA) to study their effect on growth, gene transcription and general oxidation. The results of 4 separate trials were averaged and compared for significance using one way ANOVA and Student’s t-test.Results: C18:3(n-3), DHA and CLA-t10c12 were inhibitory to 3t3 adipose cell growth and caused significant lipid hydro peroxide activity. CLA-t10c12 and c9t11 increased AFABP, FAS and ACOX1 mRNA expression but DHA and C18:3(n-3) decreased the same mRNAs. CLA-c9t11 but not the t10c12 stimulated adipoQ expression even though; c9t11 had only a slightly greater affinity for PPARγ than CLA- t10c12. The expression of the xenobiotic metabolism genes, aldo-keto reductase 1c1 (akr1c1), superoxide dismutase (SOD) and inflammation chemokine secretions of eotaxin (CCL11), Rantes (CCL5), MIG (CCL9) and MCP-1 were increased by DHA, C18:3(n-3) and CLA-t10c12. This correlated with apoptosis factors, caspase 3, Bcl-2 and BAXs which were partially reduced by co-treatment with lipophilic anti-oxidant α-tocopherol.Conclusions: Based on this evidence, CLA-t10c12 promoted more reactive oxygen species (ROS) than CLAc9t11, in a similar effect as C18:3(n-3) and DHA. In response, cascades of genes are activated to deal with the potentially damaging effects of ROS through detoxification, inflammation or apoptosis.Keywords: CLA-t10c12, CLA-c9t11, gene expression, adipocyte lipid hydroperoxide, DHA,3T3 adipocytes, apoptosis.

Published: August 2018

Background: Thunbergia laurifolia is a Thai herb and has been used in Thai folklore medicine for centuries. Generally, Thais consume T. laurifolia as a herbal tea because of its beneficial properties as an antidote for chemical toxins, drug-, arsenic-, strychnine-, alcohol- and food-poisoning. However, its effectively against some insecticide compounds, e.g. methomyl, has not yet been determined.Objective: To examine the protective effect of aqueous extract from leaves of T. laurifolia on methomyl (MT) poisoning of murine macrophage cells (anti-MT effect) and to identify phenolic and flavonoid compounds in the extract. Methods: T. laurifolia was extracted with water and stored in freeze-dried form. The extract was investigated for its antioxidant activity and some phenolic and flavonoid compounds were identified using liquid chromatography–mass spectrometry (LC-MS). To study anti-MT effects in RAW264.7 murine macrophage cells, these were treated with leaf extract either before (pre-treatment), concomitantly (combined) or after (post-treatment) exposure to MT and cell viability determined in an MTT test (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide).Results: The extract exhibited strong antioxidant properties based on total extractable phenolic content (TPC), total extractable flavonoid content (TFC), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and Ferric ion reducing antioxidant power (FRAP) activity. The LC-MS analyses of phenolic compounds indicated the presence of caffeic acid, rosmarinic acid, catechin, rutin, isoquercetin, quercetin and apigenin as bioactive compounds. Viability of RAW 264.7 murine macrophage cells treated with MT was increased significantly by post-treatment with leaf extract but not by combined or pre-treatments. Conclusion: The aqueous extract of T. laurifolia leaves contained abundant antioxidant activity. Flavonoids present were catechin, rutin, isoquercetin, quercetin and apigenin. The aqueous leaf extract was able to help cells recover from the effects of exposure to MT.Keywords: Thunbergia laurifolia, phenolics, flavonoids, methomyl, RAW264.7 murine macrophages, insecticide
