RESUMEN

BACKGROUND: Dietary behavior and nutrient intake patterns among U.S. men and women with inflammatory bowel disease (IBD) are unclear at the population level. METHODS: This cross-sectional study compared dietary intake patterns among U.S. adults (aged ≥18 years) with and without IBD in the 2015 National Health Interview Survey (N = 33,626). Age-standardized weighted prevalences for intake of fruits, vegetables, dairy, whole grain bread, dietary fiber, calcium, total added sugars, sugar-sweetened beverages (SSBs), processed meat, and supplement use were compared between adults with and without IBD by sex. RESULTS: In 2015, an estimated 3 million adults (1.3%) reported IBD. Compared with adults without IBD, adults with IBD were more likely to be older, non-Hispanic white, not currently working, former smokers, and former alcohol drinkers. Overall, dietary behaviors were similar among adults with and without IBD. However, adults with IBD were more likely to take vitamin D supplements (31.5% vs 18.8%) and consume dietary fiber <16.7 grams(g)/day, the amount that 50% of U.S. adults consumed (51.8% vs 44.1%), than those without IBD. Compared with their counterparts, men with IBD were more likely to consume vegetables ≥1 time/day (84.9% vs 76.0%) and take any supplement (59.6% vs 46.0%); women with IBD were more likely to have SSBs ≥2 times/day (26.8% vs 17.8%) and total added sugars ≥14.6 teaspoons(tsp)/day, the amount that 50% of U.S. adults consumed (55.3% vs 46.7%). CONCLUSIONS: Adopting a healthy diet, especially limiting added sugars intake among women with IBD, might be important for the overall health.

RESUMEN

This study aimed to investigate the effect of resistant starch from green banana (GB) on steatosis and short-chain fatty acid (SCFAs) production in high fat diet-induced obesity in mice. High-fat green banana group (HFB) exhibited lower gains in BM (body mass; -6%; P < 0.01) compared with High-fat diet group (HF). Additionally, HFB mice showed reduction in liver steatosis (-28%, P < 0.01) with reduction of 93% in hepatic triacylglycerol (P < 0.01) compared to HF-diet-fed mice. In addition, the protein abundance of AMPKp/AMPK, HMGCoA-r and FAS were downregulated in livers of HFB mice (P < 0.01), relatively to the HF-diet-fed mice. ABCG8 and ABCG5 were up-regulated in HFB group compared to HF group (P < 0.01). Furthermore, the HFB fed-mice produced the highest amount of SCFAs (p < 0.05) compared to its counterpart HFD. In conclusion, we demonstrated that resistant starch from GB improved metabolic parameters by modulating the expression of key proteins involved in liver lipid metabolism.

RESUMEN

High red meat intake is associated with the risk of colorectal cancer (CRC), whereas dietary fibers, such as resistant starch (RS) seemed to protect against CRC. The aim of this study was to determine whether high-amylose potato starch (HAPS), high-amylose maize starch (HAMS), and butyrylated high-amylose maize starch (HAMSB)-produced by an organocatalytic route-could oppose the negative effects of a high-protein meat diet (HPM), in terms of fermentation pattern, cecal microbial composition, and colonic biomarkers of CRC. Rats were fed a HPM diet or an HPM diet where 10% of the maize starch was substituted with either HAPS, HAMS, or HAMSB, for 4 weeks. Feces, cecum digesta, and colonic tissue were obtained for biochemical, microbial, gene expression (oncogenic microRNA), and immuno-histochemical (O6-methyl-2-deoxyguanosine (O6MeG) adduct) analysis. The HAMS and HAMSB diets shifted the fecal fermentation pattern from protein towards carbohydrate metabolism. The HAMSB diet also substantially increased fecal butyrate concentration and the pool, compared with the other diets. All three RS treatments altered the cecal microbial composition in a diet specific manner. HAPS and HAMSB showed CRC preventive effects, based on the reduced colonic oncogenic miR17-92 cluster miRNA expression, but there was no significant diet-induced differences in the colonic O6MeG adduct levels. Overall, HAMSB consumption showed the most potential for limiting the negative effects of a high-meat diet.

RESUMEN

BACKGROUND & AIMS: The purpose of this study was to assess nutritional status, quality of life (QoL) and function in malnourished or at risk for malnutrition community-dwelling (CD) and nursing home-dwelling (NHD) elderly patients with type 2 diabetes mellitus (DM2), receiving treatment with a diabetes-specific oral nutritional supplement (DSONS). METHODS: A prospective, multicentre, observational study was conducted. A DSONS (high-calorie, high-protein, with slow-digestible carbohydrate and high monounsaturated fatty acid - MUFA-content - Glucerna® 1.5 Cal) had been prescribed the week before inclusion. The following assessments were undertaken at baseline (BL), at week 6 (V1) and at month 3 (FV): body mass index (BMI), glycosylated haemoglobin (HbA1c), nutritional status (Mini Nutritional Assessment - MNA), QoL (EQ-5D questionnaire), and functional status (Katz Index - KI of Independence in Activities of Daily Living). The data were reported in the overall population (OP) and in the CD and NHD groups. RESULTS: A total of 402 patients aged 80.8 ± 8.5 years were evaluable (44.5% men), including 61.7% CD and 38.3% NHD. BMI (kg/m2) increased in the OP from 22.0 ± 3.5 at BL to 22.5 ± 3.6 at V1 (p < 0.001) and 23.0 ± 3.7 at the FV (p < 0.001). BMI also increased in the CD group (p < 0.001) and in the NHD group (p < 0.001). HbA1c decreased in the OP from 7.3 ± 1.1% at BL to 7.2 ± 1.0% at V1 and 7.0 ± 0.9% at the FV (p < 0.001), in both the CD (p < 0.001) and the NHD groups (p = 0.020). The mean overall MNA score increased in the OP from 13.1 ± 4.8 at BL to 17.0 ± 4.7 at V1 and 18.6 ± 5.1 at the FV (p < 0.001). The mean overall MNA score also increased in the CD (p < 0.001) and the NHD groups (p < 0.001). The mean overall EQ-5D score improved in the OP from 46.0 ± 18.0 at BL to 54.8 ± 17.5 at V1 and 59.7 ± 18.8 at the FV (p < 0.001). The mean overall EQ-5D score also improved in the CD (p < 0.001) and the NHD groups (p < 0.001). Gastrointestinal adverse events were seen in only 2% of patients. Treatment compliance was 94.4%. CONCLUSIONS: In this study, conducted in routine, multicentre, clinical settings, the treatment with the high-calorie, high-protein, with slow-digestible carbohydrate, and high MUFA content DSNOS - Glucerna® 1.5 Cal-, was associated with improvements in HbA1c, nutritional status, BMI and QoL following 6 weeks and 3 months of treatment in both institutionalised and non-institutionalised elderly patients with diabetes who were malnourished or at risk for malnutrition. A slight improvement in functional status was also observed at 12 weeks. As this is an observational effectiveness study, a randomized controlled trial would be necessary to establish a causal relationship between the DSNOS and the described events.

RESUMEN

BACKGROUND: Inflammatory bowel disease (IBD), comprised of Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic mucosal inflammation, frequent hospitalizations, adverse health economics, and compromised quality of life. Diet has been hypothesised to influence IBD activity. OBJECTIVES: To evaluate the efficacy and safety of dietary interventions on IBD outcomes. SEARCH METHODS: We searched the Cochrane IBD Group Specialized Register, CENTRAL, MEDLINE, Embase, Web of Science, Clinicaltrials.gov and the WHO ICTRP from inception to 31 January 2019. We also scanned reference lists of included studies, relevant reviews and guidelines. SELECTION CRITERIA: We included randomized controlled trials (RCTs) that compared the effects of dietary manipulations to other diets in participants with IBD. Studies that exclusively focused on enteral nutrition, oral nutrient supplementation, medical foods, probiotics, and parenteral nutrition were excluded. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, extracted data and assessed bias using the risk of bias tool. We conducted meta-analyses where possible using a random-effects model and calculated the risk ratio (RR) and corresponding 95% confidence interval (CI) for dichotomous outcomes. We assessed the certainty of evidence using GRADE. MAIN RESULTS: The review included 18 RCTs with 1878 participants. The studies assessed different dietary interventions for active CD (six studies), inactive CD (seven studies), active UC (one study) and inactive UC (four studies). Dietary interventions involved either the consumption of low amounts or complete exclusion of one or more food groups known to trigger IBD symptoms. There was limited scope for data pooling as the interventions and control diets were diverse. The studies were mostly inadequately powered. Fourteen studies were rated as high risk of bias. The other studies were rated as unclear risk of bias.The effect of high fiber, low refined carbohydrates, low microparticle diet, low calcium diet, symptoms-guided diet and highly restricted organic diet on clinical remission in active CD is uncertain. At 4 weeks, remission was induced in: 100% (4/4) of participants in the low refined carbohydrates diet group compared to 0% (0/3) of participants in the control group (RR 7.20, 95% CI 0.53 to 97.83; 7 participants; 1 study; very low certainty evidence). At 16 weeks, 44% (23/52) of participants in the low microparticle diet achieved clinical remission compared to 25% (13/51) of control-group participants (RR 3.13, 95% CI 0.22 to 43.84; 103 participants; 2 studies; I² = 73%; very low certainty evidence). Fifty per cent (16/32) of participants in the symptoms-guided diet group achieved clinical remission compared to 0% (0/19) of control group participants (RR 20.00, 95% CI 1.27 to 315.40; 51 participants ; 1 study; very low certainty evidence) (follow-up unclear). At 24 weeks, 50% (4/8) of participants in the highly restricted organic diet achieved clinical remission compared to 50% (5/10) of participants in the control group (RR 1.00, 95% CI 0.39 to 2.53; 18 participants; 1 study; very low certainty evidence). At 16 weeks, 37% (16/43) participants following a low calcium diet achieved clinical remission compared to 30% (12/40) in the control group (RR 1.24, 95% CI 0.67 to 2.29; 83 participants; 1 study; very low certainty evidence).The effect of low refined carbohydrate diets, symptoms-guided diets and low red processed meat diets on relapse in inactive CD is uncertain. At 12 to 24 months, 67% (176/264) of participants in low refined carbohydrate diet relapsed compared to 64% (193/303) in the control group (RR 1.04, 95% CI 0.87 to 1.25; 567 participants; 3 studies; I² = 35%; low certainty evidence). At 6 to 24 months, 48% (24/50) of participants in the symptoms-guided diet group relapsed compared to 83% (40/48) participants in the control diet (RR 0.53, 95% CI 0.28 to 1.01; 98 participants ; 2 studies; I² = 54%; low certainty evidence). At 48 weeks, 66% (63/96) of participants in the low red and processed meat diet group relapsed compared to 63% (75/118) of the control group (RR 1.03, 95% CI 0.85 to 1.26; 214 participants; 1 study; low certainty evidence). At 12 months, 0% (0/16) of participants on an exclusion diet comprised of low disaccharides / grains / saturated fats / red and processed meat experienced clinical relapse compared to 26% (10/38) of participants on a control group (RR 0.11, 95% CI 0.01 to 1.76; 54 participants; 1 study; very low certainty evidence).The effect of a symptoms-guided diet on clinical remission in active UC is uncertain. At six weeks, 36% (4/11) of symptoms-guided diet participants achieved remission compared to 0% (0/10) of usual diet participants (RR 8.25, 95% CI 0.50 to 136.33; 21 participants; 1 study; very low certainty evidence).The effect of the Alberta-based anti-inflammatory diet, the Carrageenan-free diet or milk-free diet on relapse rates in inactive UC is uncertain. At 6 months, 36% (5/14) of participants in the Alberta-based anti-inflammatory diet group relapsed compared to 29% (4/14) of participants in the control group (RR 1.25, 95% CI 0.42 to 3.70; 28 participants; 1 study; very low certainty evidence). Thirty per cent (3/10) of participants following the carrageenan-free diet for 12 months relapsed compared to 60% (3/5) of the participants in the control group (RR 0.50, 95% CI 0.15 to 1.64; 15 participants; 1 study; very low certainty evidence). At 12 months, 59% (23/39) of milk free diet participants relapsed compared to 68% (26/38) of control diet participants (RR 0.83, 95% CI 0.60 to 1.15; 77 participants; 2 studies; I² = 0%; low certainty evidence).None of the included studies reported on diet-related adverse events. AUTHORS' CONCLUSIONS: The effects of dietary interventions on CD and UC are uncertain. Thus no firm conclusions regarding the benefits and harms of dietary interventions in CD and UC can be drawn. There is need for consensus on the composition of dietary interventions in IBD and more RCTs are required to evaluate these interventions. Currently, there are at least five ongoing studies (estimated enrollment of 498 participants). This review will be updated when the results of these studies are available.

RESUMEN

Blackcurrants (Ribes nigrum L.) have various benefits for human health. In particular, a polysaccharide derived from blackcurrant was found to be an immunostimulating food ingredient in a mouse model. We named a polysaccharide derived from blackcurrant cassis polysaccharide (CAPS). In a previous clinical study, we reported that CAPS affects skin dehydration, demonstrating its effectiveness against skin inflammation was related to atopic dermatitis; skin inflammation caused skin dehydration. However, there are no studies regarding CAPS effectiveness against skin dehydration. The current study aimed to investigate CAPS effectiveness against skin dehydration. We further demonstrate the effect of oral administration of CAPS on skin dehydration caused by ultraviolet (UV) irradiation-induced inflammation in mice. We found that CAPS administration suppresses skin dehydration caused by UV irradiation. We also found that CAPS decreases interleukin-6 and matrix metalloproteinase transcription levels in the mouse skin. These results show that CAPS improves skin hydration in UV-irradiated mice.

RESUMEN

BACKGROUND: In pediatric short bowel syndrome (SBS), adding fiber to enteral feedings is 1 treatment method to manage increased stool output. However, there are no standardized recommendations on the use of fiber in this setting, including type, dosage, titration strategies, etc. OBJECTIVE: The aim of this study is to determine current prevailing practices on the use of fiber in the treatment of chronic high stool output in the pediatric SBS population. METHODS: An anonymous electronic survey with 13 questions was sent through health professional electronic mailing lists. The survey was completed by healthcare professionals including physicians (primary care, subspecialists, and surgeons), nurse practitioners, and registered dietitians. RESULTS: A total of 94 responses were received. The most common supplemental fiber used was pectin (62.8%). The 2 major factors considered when initiating fiber therapy were consistency of stool (74.5%) and volume of stool output (85.1%). The major factor that determined discontinuation of fiber was abdominal distention (67%). A majority of providers waited 2 weeks or less to see improvement following fiber initiation before discontinuing it. CONCLUSIONS: The goal of the survey was to gather more information with regard to fiber use in the management of SBS patients. The data collected can be used to provide future direction on determining best practices for fiber use in SBS patients.

RESUMEN

The effects of protein supplementation on the ratings of energy/fatigue, muscle soreness [ascending (A) and descending (D) stairs], and serum creatine kinase levels following a marathon run were examined. Variables were compared between recreational male and female runners ingesting carbohydrate + protein (CP) during the run (CPDuring, n = 8) versus those that were consuming carbohydrate (CHODuring,n = 8). In a second study, outcomes were compared between subjects who consumed CP or CHO immediately following exercise [CPPost (n = 4) versus CHOPost (n = 4)]. Magnitude-based inferences revealed no meaningful differences between treatments 24 h post-marathon. At 72 h, recovery [Δ(72 hr-Pre)] was likely improved with CPDuring versus CHODuring, respectively, for Physical Energy (+14 ± 64 vs -74 ± 70 mm), Mental Fatigue (-52 ± 59 vs +1 ± 11 mm), and Soreness-D (+15 ± 9 vs +21 ± 70 mm). In addition, recovery at 72 h was likely-very likely improved with CPPost versus CHOPost for Physical Fatigue, Mental Energy, and Soreness-A. Thus, protein supplementation did not meaningfully alter recovery during the initial 24 h following a marathon. However, ratings of energy/fatigue and muscle soreness were improved over 72 h when CP was consumed during exercise, or immediately following the marathon.

RESUMEN

During prolonged resistance training, protein supplementation is known to promote morphological changes; however, no previous training studies have tested the effect of insect protein isolate in a human trial. The aim of this study was to investigate the potential effect of insect protein as a dietary supplement to increase muscle hypertrophy and strength gains during prolonged resistance training in young men. Eighteen healthy young men performed resistance training four day/week for eight weeks. Subjects were block randomized into two groups consuming either an insect protein isolate or isocaloric carbohydrate supplementation within 1 h after training and pre-sleep on training days. Strength and body composition were measured before and after intervention to detect adaptions to the resistance training. Three-day weighed dietary records were completed before and during intervention. Fat- and bone- free mass (FBFM) improved significantly in both groups (Mean (95% confidence interval (CI))), control group (Con): (2.5 kg (1.5, 3.5) p < 0.01), protein group (Pro): (2.7 kg (1.6, 3.8) p < 0.01) from pre- to post-. Leg and bench press one repetition maximum (1 RM) improved by Con: (42.0 kg (32.0, 52.0) p < 0.01) and (13.8 kg (10.3, 17.2) p < 0.01), Pro: (36.6 kg (27.3, 45.8) p < 0.01) and (8.1 kg (4.5, 11.8) p < 0.01), respectively. No significant differences in body composition and muscle strength improvements were found between groups. In young healthy men, insect protein supplementation did not improve adaptations to eight weeks of resistance training in comparison to carbohydrate supplementation. A high habitual protein intake in both Con and Pro may partly explain our observation of no superior effect of insect protein supplementation.

RESUMEN

We investigated if a carbohydrate (CHO) mouth rinse may attenuate global fatigue and improve 4-km cycling time trial (TT4km) performance. After a preliminary session, cyclists (n = 9) performed a TT4km after a CHO or placebo (PLA) mouth rinse. Mean power output, time, and ratings of perceived exertion (RPE) were recorded throughout the TT4km. Twitch interpolation responses (%VA; voluntary activation and ∆Tw; delta peak twitch torque) were compared pre and post TT4km with traditional statistics and effect size (ES) analysis. Time-to-complete the 4 km and mean power output were comparable between CHO (386.4 ± 28.0 s) and PLA (385.4 ± 22.4 s). A lower central (p = 0.054) and peripheral (p = 0.02) fatigue in CHO than in PLA were suggested by an extremely-large ES in %VA (manipulation main effect: p = 0.052, d = 1.18; manipulation-by-time interaction effect: p = 0.08, d = 1.00) and an extremely, very-large ES in ∆Tw (manipulation main effect: p = 0.07, d = 0.97; time-by-manipulation interaction effect: p = 0.09, d = 0.89). The RPE increased slower in CHO than in PLA (p = 0.051; d = 0.7). The apparent reduction in global fatigue (central and peripheral) and RPESLOPE with only one CHO mouth rinse were not translated into improved TT4km performance. Further tests may be required to verify if these likely differences in global fatigue might represent an edge in the short-lasting cycling time trial performance.

RESUMEN

This review examines the effects of carbohydrates, delivered individually and in combination with caffeine, on a range of cognitive domains and subjective mood. There is evidence for beneficial effects of glucose at a dose of 25 g on episodic memory, but exploration of dose effects has not been systematic and the effects on other cognitive domains is not known. Factors contributing to the differential sensitivity to glucose facilitation include age, task difficulty/demand, task domain, and glucoregulatory control. There is modest evidence to suggest modulating glycemic response may impact cognitive function. The evidence presented in this review identifies dose ranges of glucose and caffeine which improve cognition, but fails to find convincing consistent synergistic effects of combining caffeine and glucose. Whilst combining glucose and caffeine has been shown to facilitate cognitive performance and mood compared to placebo or glucose alone, the relative contribution of caffeine and glucose to the observed effects is difficult to ascertain, due to the paucity of studies that have appropriately compared the effects of these ingredients combined and in isolation. This review identifies a number of methodological challenges which need to be considered in the design of future hypothesis driven research in this area.

RESUMEN

Polysaccharides are an important class of phytochemicals, and many studies have demonstrated their beneficial effects in the context of a number of pathologies including neurological disorders. Numerous studies have indicated that polysaccharides exhibit neuroprotection through a variety of mechanisms. We performed a comprehensive review of the literature to consolidate studies for the period 2010-2016, and assessed the protection mechanisms on brain function of polysaccharide-rich extracts from natural sources. Studies were identified by conducting electronic searches on PubMed, Web of Science and Google Scholar. Reference lists of articles were also reviewed for additional relevant studies. Only articles published in English were included in this review. In total, 21 types of polysaccharides from 16 kinds of plants sources have shown neuroprotective properties. In vivo and in vitro experiments have demonstrated the ability of polysaccharide-rich extracts to provide neuroprotective effects through promotion of neurite outgrowth, and NF-κB, PI3K/Akt, MAPK, Nrf2/HO-1 signaling pathways. This review will give a better understanding of the neurotrophic effects of polysaccharides and the concomitant modulations of signaling pathways. It is useful for designing more effective agents for management of neurological diseases.

RESUMEN

SCOPE: Independently, prebiotics and dietary protein have been shown to improve weight loss and/or alter appetite. Our objective was to determine the effect of combined prebiotic and whey protein on appetite, body composition and gut microbiota in adults with overweight/obesity. METHODS AND RESULTS: In a 12 week, placebo-controlled, double-blind study, 125 adults with overweight/obesity were randomly assigned to receive isocaloric snack bars of: (1) Control; (2) Inulin-type fructans (ITF); (3) Whey protein; (4) ITF + Whey protein. Appetite, body composition and gut microbiota composition/genetic potential were assessed. Compared to Control, body fat was significantly reduced in the Whey protein group at 12 wks. Hunger, desire to eat and prospective food consumption were all lower with ITF, Whey protein and ITF + Whey protein compared to Control at 12 wks. Microbial community structure differed from 0 to 12 wks in the ITF and ITF +Whey Protein groups (i.e. increased Bifidobacterium) but not Whey Protein or Control. Changes in microbial genetic potential were seen between Control and ITF-containing treatments. CONCLUSION: Adding ITF, whey protein or both to snack bars improved several aspects of appetite control. Changes in gut microbiota may explain in part the effects of ITF but likely not whey protein.

RESUMEN

Introduction: Fibromyalgia is a chronic rheumatic disease producing widespread pain, associated to a major comorbidity -irritable bowel syndrome. Low FODMAPS diet (low fermentable oligo-di-mono-saccharides and polyols diet) has been effective in controlling irritable bowel syndrome symptoms. Overweight is an aggravating factor for fibromyalgia. We studied effects of low fermentable oligo-di-mono-saccharides and polyols diets on fibromyalgia symptoms and weight status. Methods: A longitudinal study was performed on 38 fibromyalgia patients using a four-week, repeated assessment as follow: M1 = first assessments/presentation of individual low fermentable oligo-di-mono-saccharides and polyols diet; M2 = second assessments/reintroduction of FODMAPs; M3 = final assessments/nutritional counselling. The assessment instruments applied were: Fibromyalgia Survey Questionnaire (FSQ); Severity Score System (IBS-SSS); visual analogic scale (VAS). Body mass-index/composition and waist circumference (WC) were also measured. Daily macro-micronutrients and FODMAP intake were quantified at each moment of the study. Results: The studied cohort was 37% overweight, 34% obese (average body mass-index 27.4 ± 4.6; excess fat mass 39.4 ± 7%). Weight, body mass-index and waist circumference decreased significantly (p < 0.01) with low fermentable oligo-di-mono-saccharides and polyols diet, but no significant effect on body composition was observed. All fibromyalgia symptoms, including somatic pain, declined significantly post-LFD (p < 0.01); as well for severity of fibromyalgia [Fibromyalgia survey questionnaire: M1 = 21.8; M2 = 16.9; M3 = 17.0 (p < 0.01)]. The intake of essential nutrients (fiber, calcium, magnesium and vitamin D) showed no significant difference. The significant reduction in FODMAP intake (M1 = 24.4 g; M2 = 2.6g; p < 0.01) reflected the «Diet adherence» (85%). «Satisfaction with improvement of symptoms» (76%), showed correlating with «diet adherence» (r = 0.65; p < 0.01). Conclusions: Results are highly encouraging, showing low fermentable oligo-di-mono-saccharides and polyols diets as a nutritionally balanced approach, contributing to weight loss and reducing the severity of FM fibromyalgia symptoms (AU)


Introducción: la fibromialgia es una enfermedad reumática crónica, que tiene unas importantes comorbilidades-síndrome del intestino irritable (SII). La dieta baja en FODMAPs (low fermentable oligo-di-mono-saccharides and polyols diet) ha sido eficaz en el tratamiento del síndrome del intestino irritable. El sobrepeso es un factor agravante. Se estudiaron los efectos nutricionales del FODMAPs en la fibromialgia. Métodos: estudio longitudinal en 38 pacientes con fibromialgia en el que se utilizó una evaluación repetida, durante cuatro semanas, de lo siguiente: Moment 1 (M1) = primeras evaluaciones/presentación de FODMAPs; M2 = segundas evaluaciones/reintroducción de FODMAPs; M3 = evaluaciones finales/asesoramiento nutricional. Instrumentos de evaluación: Fibromialgia Survey Questionnaire; síndrome del intestino irritable (IBS-SSS), escala visual analógica (EVA) y parámetros antropométricos. Cuantificación en todo momento de las ingestas diarias de macro/micro nutrientes y FODMAPs. Resultados: el estudio de cohorte mostró 37% de sobrepeso y 34% obesidad; índice de masa corporal = 27,4 ± 4,6; masa grasa = 39,4 ± 7%. El peso y la circunferencia de la cintura disminuyeron significativamente con FODMAPs, pero no cambió la composición corporal. Los síntomas y la severidad de la fibromialgia (FSQ: M1 = 21,8; M2 = 16,9; M3 = 17,0) se redujeron significativamente después de FODMPAs (p < 0,01). No fueron observadas diferencias significativas en el consumo de nutrientes esenciales, especialmente la fi bra, calcio, magnesio y vitamina D. El «seguimiento de la dieta» fue del 85% con reducción significativa de la ingesta de FODMAPs (p < 0,01: M1 = 24,4 g; M2 = 2,6 g). «La satisfacción con la mejora de los síntomas» (76%) se correlacionó con el «seguimiento de la dieta» (r = 0,65; p < 0,01). Conclusiones: los resultados son muy alentadores, mostrando FODMAPs como un enfoque equilibrado nutricionalmente, que contribuyó a la pérdida de peso y redujo significativamente la severidad de la FM (AU)

RESUMEN

Background: The incidence of type 2 diabetes (T2D) is increasing worldwide, and nutritional management of circulating glucose may be a strategic tool in the prevention of T2D.Objective: We studied whether enzymatically modified waxy maize with an increased degree of branching delayed the onset of diabetes in male Zucker diabetic fatty (ZDF) rats.Methods: Forty-eight male ZDF rats, aged 5 wk, were divided into 4 groups and fed experimental diets for 9 wk that contained 52.95% starch: gelatinized corn starch (S), glucidex (GLU), resistant starch (RS), or enzymatically modified starch (EMS). Blood glucose after feed deprivation was assessed every second week; blood samples taken at run-in and at the end of the experiment were analyzed for glycated hemoglobin (HbA1c) and plasma glucose, insulin, and lipids. During weeks 2 and 8, urine was collected for metabolomic analysis.Results: Based on blood glucose concentrations in feed-deprived rats, none of the groups developed diabetes. However, in week 9, plasma glucose after feed deprivation was significantly lower in rats fed the S and RS diets (13.5 mmol/L) than in rats fed the GLU and EMS diets (17.0-18.9 mmol/L), and rats fed RS had lower HbA1c (4.9%) than rats fed the S, GLU, and EMS (5.6-6.1%) diets. The homeostasis model assessment of insulin resistance was significantly lower in rats fed RS than in rats fed the other diets (185 compared with 311-360), indicating that rats fed the S, GLU, and EMS diets were diabetic, and a 100% higher urine excretion during week 8 in rats fed the GLU and EMS diets than that of rats fed S and RS showed that they were diabetic. Urinary nontargeted metabolomics revealed that the diabetic state of rats fed S, GLU, and EMS diets influenced microbial metabolism, as well as amino acid, lipid, and vitamin metabolism.Conclusions: EMS did not delay the onset of diabetes in ZDF rats, whereas rats fed RS showed no signs of diabetes.

RESUMEN

BACKGROUND: The first British Dietetic Association (BDA) guidelines for the dietary management of irritable bowel syndrome (IBS) in adults were published in 2012. Subsequently, there has been a wealth of new research. The aim of this work was to systematically review the evidence for the role of diet in the management of IBS and to update the guidelines. METHODS: Twelve questions relating to diet and IBS were defined based on review of the previous guideline questions, current evidence and clinical practice. Chosen topics were on healthy eating and lifestyle (alcohol, caffeine, spicy food, elimination diets, fat and fluid intakes and dietary habits), milk and dairy, dietary fibre, fermentable carbohydrates, gluten, probiotics and elimination diets/food hypersensitivity. Data sources were CINAHL, Cochrane Register of Controlled Trials, Embase, Medline, Scopus and Web of Science up to October 2015. Studies were assessed independently in duplicate using risk of bias tools specific to each included study based on inclusion and exclusion criteria for each question. National Health and Medical Research Council grading evidence levels were used to develop evidence statements and recommendations, in accordance with Practice-based Evidence in Nutrition Global protocol used by the BDA. RESULTS: Eighty-six studies were critically appraised to generate 46 evidence statements, 15 clinical recommendations and four research recommendations. The IBS dietary algorithm was simplified to first-line (healthy eating, provided by any healthcare professional) and second-line [low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) to be provided by dietitian] dietary advice. CONCLUSIONS: These guidelines provide updated comprehensive evidence-based details to achieve the successful dietary management of IBS in adults.

RESUMEN

Worldwide experience of Traditional medicine (TM) has been successfully applied to the development of modern standardized herbal medicines. Mainly researchers are guided by local sources of medicinal plants and traditional medical systems. TM experience is also used in the search of plants considered as sources of biologically active substances (BAS) and food ingredients. The steady increase in the incidence of type 2 diabetes, makes clear the need for research of domestic plant sources of BAS (with a proven carbohydrate metabolism effect) to create modern specialized foods. This article proves the feasibility of using TM experience of Russia and some neighboring European countries (Belarus, Ukraine) to develop optimized compositions for specialized food products for patients with type 2 diabetes. For reliable identification of the most promising plants, 550 traditional antidiabetic herbal formulations of 66 traditional recipe directories were studied in Russia, Belarus and Ukraine. It revealed 37 species of plants included to more than 20% of all bibliographical sources, and 13 plants included to more than 50% of prescription directories. The 3 most popular are bilberry leaves, leaffruit of common bean, great nettle leaves.

RESUMEN

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide, with a prevalence of 20%-40% in Western populations. The purpose of this article is to review data related to lifestyle changes in patients with NAFLD. METHOD: We searched a public domain database (PubMed) with the following categories: disease (NAFLD, fatty liver, and non-alcoholic steatohepatitis [NASH]) and intervention (lifestyle intervention, diet, nutrition) with each possible combination through 25 September 2014, for relevant articles. Review of articles was restricted to those published in English. We selected the studies involving adult patients only. CONCLUSION: There is no consensus as to what diet or lifestyle approach is the best for NAFLD patients. However, patients with NAFLD may benefit from a moderate- to low-carbohydrate (40%-45% of total calories) diet, coupled with increased dietary MUFA and n-3 PUFAs, reduced SFAs. More CRT are needed to clarify the specific effects of different diets and dietary components on the health of NAFLD patients. ABBREVIATIONS: NAFL = Non-alcoholic fatty liver, NAFLD = non-alcoholic fatty liver disease, NASH = non-alcoholic steatohepatitis, HCC = hepatocarcinoma, BEE = basal energy expenditure, CRT = A small clinical randomized trial showed that short-term carbohydrate restriction is more efficacious in reducing intrahepatic triglyceride, IHT = intrahepatic triglyceride, VLCD = Very low calorie diets, AST = aspartate aminotransferases, SFAs = saturated fatty acids.

RESUMEN

Sub-health has been described as a chronic condition of unexplained deteriorated physiological function, which falls between health and illness and includes fatigue as one of its principal manifestations. Mitochondrial dysfunctions have been discovered in fatigue-type sub-health such as impaired oxidative phosphorylation and mitochondrial damage. In the present study, we evaluated the effects of Lycium barbarum polysaccharide (LBP-4a), a polysaccharide fraction purified from Lycium barbarum, on anti-fatigue in sub-health mice, and the relevant mechanisms were studied. Forty mice were divided into control, model, LBP-4a(L) and LBP-4a(H) groups. Model mice were prepared through compound factors, including forced swim tests, sleep deprivation and wrapping restraint stress tests. After LBP-4a treatment for 4 weeks, the gastrocnemius muscles were obtained for morphological observation and the activities of SOD, GSH-Px and MDA content were detected. Furthermore, mitochondrial membrane potential and Ca(2+) content were measured in isolated skeletal muscle mitochondria. The results showed that LBP-4a could reduce skeletal muscle damage and MDA levels and enhance of SOD and GSH-Px activities compared with the model group. The levels of mitochondrial membrane potential and Ca(2+) were increased in LBP-4a-treated skeletal muscle mitochondria; moreover, the high-dosage group was better than that of the low dosage. In conclusion, LBP-4a exhibited anti-fatigue activity on sub-health mice, and the mechanism was closely correlated with a reduction in lipid peroxidation levels and an increase in antioxidant enzyme activities in skeletal muscle tissue, improving the intracellular calcium homeostasis imbalance and increasing mitochondrial membrane potential. These observations provided the background for the further development of LBP-4a as a type of anti-fatigue therapy used in sub-health treatment.
