The objective of this study was to identify genes altered by carcinogen treatment in normal-appearing colonic mucosa and those attenuated by bean feeding. Ninety-five male F344 rats were fed control (AIN) diets upon arrival. At 4 and 5 weeks, rats were injected with AOM (15&amp;#x2009;mg/kg) or saline and one week later administered an AIN, BB-, or SF-based diet. Rats were sacrificed after 31 weeks, and microarrays were conducted on RNA isolated from the distal colonic mucosa. AOM treatment induced a number of genes involved in immunity, including several MHC II-associated antigens and innate defense genes (RatNP-3, Lyz2, Pla2g2a). BB- and SF-fed rats exhibited a higher expression of genes involved in energy metabolism and water and sodium absorption and lower expression of innate (RatNP-3, Pla2g2a, Tlr4, Dmbt1) and cell cycle-associated (Cdc2, Ccnb1, Top2a) genes. Genes involved in the extracellular matrix (Col1a1, Fn1) and innate immunity (RatNP-3, Pla2g2a) were induced by AOM in all diets, but to a lower extent in bean-fed animals. This profile suggests beans inhibit colon carcinogenesis by modulating cellular kinetics and reducing inflammation, potentially by preserving mucosal barrier function.</description><Author>Elizabeth A.

At screening, participants averaged 44.3&amp;#x00B1;7.8 years, BMI 33.9&amp;#x00B1;6.6&amp;#x2009;Kg/m2, and BP 144.2&amp;#x00B1;9.38/88.5&amp;#x00B1;6.03&amp;#x2009;mmHg. All consumed a control diet for one week, then were randomized to control or DASH for another two weeks (week one and two). With DASH, but not controls, SBP fell by 10.65&amp;#x00B1;12.89 (P=0.023) and 9.60&amp;#x00B1;11.23 (P=0.039)&amp;#x2009;mmHg and DBP by 5.95&amp;#x00B1;8.01 (P=0.069) and 8.60&amp;#x00B1;9.13&amp;#x2009;mmHg (P=0.011) at the end of week one and two, respectively. Univariate regressions showed that changes in urinary sodium/potassium ratio (&amp;#x03B2;=1.99) and plasma renin activity (&amp;#x03B2;=&amp;#x2212;15.78) and percent change in plasma nitrite after hyperemia were associated with SBP changes at week one (all P&amp;lt;0.05). Plasma nitrite following hyperemia showed a treatment effect (P=0.014) and increased at week two (P=0.001). Pulse wave velocity decreased over time with DASH (trend P=0.019), and reached significance at week two (P=0.026). This response may be mediated by an improvement in upregulation of nitric oxide bioavailability. Early natriuresis and reductions in oxidative stress cannot be ruled out. Future studies are needed to verify these findings, assess the possibility of earlier effects, and examine other potential mediators.</description><Author>Pao-Hwa Lin, Jason D.

Yet the effects of such practices on tissue protein metabolism are unknown. Baby pigs were fed from age 2 to 7 or 28 d with high protein formula with or without amoxicillin supplementation, in parallel with normal protein formula, to determine tissue protein metabolism modifications. Feeding high protein formula increased growth rate between 2 and 28 days of age when antibiotic was administered early in the first week of life. This could be explained by the occurrence of diarrhea when piglets were fed the high protein formula alone. Higher growth rate was associated with higher feed conversion and reduced protein synthesis rate in the small intestine, muscle and carcass, whereas proteolytic enzyme activities measured in these tissues were unchanged. In conclusion, accelerated growth rate caused by high protein formula and antibiotics was not supported by increased protein synthesis in muscle and carcass.</description><Author>Agnès Jamin, Bernard Sève, Jean-Noël Thibault, and Nathalie Floc’h</Author><copyright>Copyright &amp;#xa9; 2012 Agn&amp;#xe8;s Jamin et al.

The aim of the study is to determine how the food store environment modifies the effects of an intervention on diet among low-income women. Study Design. A 16-week face-to-face behavioral weight loss intervention was delivered among low income midlife women. 
Methods. The retail food environment for all women was characterized by (1) the number and type of food stores within census tracts; (2) availability of healthy foods in stores where participants shop; (3) an aggregate score of self-reported availability of healthy foods in neighborhood and food stores. Statistical Analyses. Multivariable linear regression was used to model the food store environment as an effect modifier between the intervention effect of fruit and vegetable serving change. Results. Among intervention participants with a low perception of availability of healthy foods in stores, the intervention effect on fruit and vegetable serving change was greater [1.89, 95% CI (0.48, 3.31)] compared to controls. Among intervention participants residing in neighborhoods with few super markets, the intervention effect on fruit and vegetable serving change was greater [1.62, 95% CI (1.27, 1.96)] compared to controls. Conclusion. Results point to how the food store environment may modify the success of an intervention on diet change among low-income women.</description><Author>Alison A.

However, there is controversy in the literature concerning its validity in reflecting muscle damage as a consequence of level and intensity of physical exercise. Nonmodifiable factors, for example, ethnicity, age, and gender, can also affect enzyme tissue activity and subsequent CK serum levels. The extent of effect suggests that acceptable upper limits of normal CK levels may need to be reset to recognise the impact of these factors. There is a need for standardisation of protocols and stronger guidelines which would facilitate greater scientific integrity.
The purpose of this paper is to examine current evidence and opinion relating to the release of CK from skeletal muscle in response to physical activity and examine if elevated concentrations are a health concern.</description><Author>Marianne F.

Malnutrition is frequently observed in patients with stroke, and dysphagia contributes to malnutrition risk. During both the acute phase of stroke and rehabilitation, specific nutritional interventions in the context of a multidisciplinary team effort can enhance the recovery of neurocognitive function. Early identification and management of malnutrition with dietary modifications or specific therapeutic strategies to ensure adequate nutritional intake should receive more attention, since poor nutritional status appears to exacerbate brain damage and to contribute to adverse outcome. The main purpose of nutritional intervention should be the prevention or treatment of complications resulting from energy-protein deficit. This paper reviews the evaluation and management of malnutrition and the use of specialized nutrition support in patients with stroke. Emphasis is given to enteral tube and oral feeding and to strategies to wean from tube feeding.</description><Author>Stella D.

Given that the effectiveness of treatment depends on the aetiology of unintentional weight loss, it is important that clinicians are aware of the defining characteristics. The aim of this study was to determine whether Australian dietitians understand and use the terms starvation, sarcopenia, and cachexia and provide targeted treatment strategies accordingly. Members of the Dietitians Association of Australia were surveyed to gain information on practices and attitudes to diagnosis and treatment of adult malnutrition. In addition, three case studies were provided to examine understanding of starvation, sarcopenia, and cachexia. 221 dietitians accessed the survey. 81 respondents (43&amp;#37;) indicated the use of at least one alternate term (starvation, sarcopenia, and/or cachexia). Muscle wasting was the most commonly used diagnostic criterion. High-energy high-protein diet was the most common therapy prescribed. Correct diagnoses for case studies were recorded by 6&amp;#37; of respondents for starvation, 46&amp;#37; for sarcopenia, and 21&amp;#37; for cachexia. There is a need for increased awareness of the existence of starvation, sarcopenia, and cachexia amongst Australian dietitians and research into appropriate methods of identification and treatment for each condition.</description><Author>Alison Yaxley and Michelle D.

We sought to examine dietary differences between African Americans (AA) and Haitian Americans (HA) with and without type 2 diabetes using the Healthy Eating Index, 2005 (HEI-05), and the Alternate Healthy Eating Index (AHEI). The design was cross-sectional N=471 (225 AA, 246 HA) and recruitment was by community outreach. The eating indices were calculated from data collected with the Harvard food-frequency questionnaire. African Americans had lower HEI-05 scores &amp;#x03B2;=&amp;#x2212;10.9 (&amp;#x2212;8.67, 13.1); SE=1.12, P&amp;#x003C;.001 than HA. Haitian American females and AA males had higher AHEI than AA females and HA males, respectively, (P=.006) adjusting for age and education. Participants with diabetes had higher adherence to the HEI-05 &amp;#x03B2;=3.90 (1.78, 6.01), SE=1.08, P&amp;#x003C;.001 and lower adherence to the AHEI &amp;#x03B2;=&amp;#x2212;9.73 (16.3, &amp;#x2212;3.19), SE=3.33, P=.004, than participants without diabetes. The findings underscore the importance of disaggregating ethnicities and disease state when assessing diet.</description><Author>Fatma G. Huffman, Maurcio De La Cera, Joan A. Vaccaro, Gustavo G.

First, a general overview of the proposed mechanisms for the beneficial effects of Gln is provided, and subsequently clinical studies are discussed. Despite safety, studies are conflicting, partly due to different effects of enteral and parenteral Gln supplementation. Further insufficient evidence is available on the benefits of Gln supplementation in pediatric patients. This includes premature infants, infants with gastrointestinal disease, children with Crohn&amp;#39;s disease, short bowel syndrome, malnutrition/diarrhea, cancer, severe burns/trauma, Duchenne muscular dystrophy, sickle cell anemia, cystic fibrosis, and type 1 diabetes. Moreover, methodological issues have been noted in some studies. Further mechanistic data is needed along with large randomized controlled trials in select populations of sick children, who may eventually benefit from supplemental Gln.</description><Author>Elise Mok and R&amp;#233;gis Hankard</Author><copyright>Copyright &amp;#xa9; 2011 Elise Mok and R&amp;#xe9;gis Hankard.

The retina has a high concentration of omega-3, particularly DHA, which optimizes fluidity of photoreceptor membranes, retinal integrity, and visual function. Furthermore, many studies demonstrated that DHA has a protective, for example antiapoptotic, role in the retina. From a nutritional point of view, it is known that western populations, particularly aged individuals, have a higher than optimal omega-6/omega-3 ratio and should enrich their diet with more fish consumption or have DHA supplementation. This paper underscores the potential beneficial effect of omega-3 fatty acids on retinal diseases.</description><Author>Giuseppe Querques, Raimondo Forte, and Eric H.

Matured tubers were cooked by roasting, baking, frying, or boiling then immediately consumed by the ten nondiabetic test subjects (5 males and 5 females; mean age of 27 &amp;#x00B1; 2 years). The GI varied between 41 &amp;#x00B1; 5&amp;#8211;93 &amp;#x00B1; 5 for the tubers studied. Samples prepared by boiling had the lowest GI (41 &amp;#x00B1; 5&amp;#8211;50 &amp;#x00B1; 3), while those processed by baking (82 &amp;#x00B1; 3&amp;#8211;94 &amp;#x00B1; 3) and roasting (79 &amp;#x00B1; 4&amp;#8211;93 &amp;#x00B1; 2) had the highest GI values. The study indicates that the glycemic index of Jamaican sweet potatoes varies significantly with the method of preparation and to a lesser extent on intravarietal differences. Consumption of boiled sweet potatoes could minimize postprandial blood glucose spikes and therefore, may prove to be more efficacious in the management of type 2 diabetes mellitus.</description><Author>Perceval S.

Soybean is a rich source of phytonutrients such as isoflavones. The objective of this study was to evaluate the chemopreventive effects of prebiotics (Synergy1) and soybean meal (SM) at 5&amp;#37; and 10&amp;#37; levels alone and in combination on azoxymethane- (AOM-) induced colon carcinogenesis. After one wk of acclimatization, Fisher 344 male rats (N=90) were randomly assigned to 9 groups (n=10). Control rats (C) were fed AIN-93G/M. Two s/c injections of AOM were administered to rats at 7 and 8&amp;#x2009;wk of age at 16&amp;#x2009;mg/kg body weight. Rats were killed by CO2 asphyxiation at 45&amp;#x2009;wk. Tumor incidence (&amp;#37;) in treatment groups ranged from 40 to 75 compared to 100 in C. Results indicate that feeding prebiotics and soybean in combination significantly reduced incidence of AOM-induced colon tumors with implications for food industry in the food-product development.</description><Author>V.

Oropharyngeal receptors signal presence of carbohydrate to the brain. Mouth rinses with a carbohydrate solution facilitate corticomotor output and improve time-trial performance in well-trained subjects in a fasted state. We tested for this effect in nonathletic subjects in fasted and nonfasted state. 
Methods. 13 healthy non-athletic males performed 5 tests on a cycle ergometer. After measuring maximum power output (Wmax), the subjects cycled four times at 60&amp;#x25; Wmax until exhaustion while rinsing their mouth every 5 minutes with either a 6.4&amp;#x25; maltodextrin solution or water, one time after an overnight fast and another after a carbohydrate rich breakfast. 
Results. Mouth rinsing with maltodextrin improved time-to-exhaustion in pre- and postprandial states. This was accompanied by reductions in the average and maximal rates of perceived exertion but no change in average or maximal heart rate was observed. 
Conclusions. Carbohydrate mouth rinsing improves endurance capacity in both fed and fasted states in non-athletic subjects.</description><Author>Elie-J. M.

Aim of this study was to compare the resting energy expenditure (REE) measured by the Douglas bag method with the REE estimated with the FitMate method, the Harris-Benedict equation, and the M&amp;#252;ller et al. equation for individuals with BMI &amp;#x003C; 18.5&amp;#x2009;kg/m2  in a severe group of underweight patients with anorexia nervosa (AN). Methods. 15 subjects with AN participated in the study. The Douglas bag method and the FitMate method were used to measure REE and the dual energy X-ray absorptiometry to assess body composition after one day of refeeding. Results. FitMate method and the M&amp;#252;ller et al. equation gave an accurate REE estimation, while the Harris-Benedict equation overestimated the REE when compared with the Douglas bag method. Conclusion. The data support the use of the FitMate method and the M&amp;#252;ller et al. equation, but not the Harris-Benedict equation, to estimate REE in AN patients after short-term refeeding.</description><Author>Marwan El Ghoch, Marta Alberti, Carlo Capelli, Simona Calugi, and Riccardo Dalle Grave</Author><copyright>Copyright &amp;#xa9; 2012 Marwan El Ghoch et al.

The association between plasma omega-6 fatty acids and cardiovascular disease (CVD) is unclear, and discrepancy remains concerning the cardiovascular benefit of the omega-3 fatty acid alpha-linolenic acid. Methods. Associations of plasma phospholipid fatty acid levels (arachidonic acid, linoleic acid, eicosapentaenoic acid, docosahexaenoic acid (DHA), and alpha-linolenic acid) with cardiac magnetic resonance imaging measures of left ventricular (LV) mass, LV volume, ejection fraction, stroke volume, and aortic distensibility were investigated in 1,274 adults. Results. Results of multivariate analysis showed no statistically significant associations of plasma omega-6 or omega-3 levels with cardiac magnetic resonance imaging measures. Stratification by gender revealed a positive association between DHA and LV mass in women (&amp;#x03B2;=1.89, P=0.02; P interaction = 0.003) and a trend for a positive association between DHA and ejection fraction in men (&amp;#x03B2;=0.009, P=0.05; P interaction = 0.03). Conclusion. Additional research is warranted to clarify the effects of plasma DHA on cardiac structure and function in women versus men.</description><Author>Jennifer S. Anderson, Jennifer A.

To determine if supplementation of protein and amino acids (PAA) decreases skeletal muscle expression of atrophy-related genes, muscle mass, and strength during immobilization in humans. Methods. Twenty males wore a lower-limb immobilization boot for 28 days and consumed either a PAA supplement (28&amp;#x2009;g protein) or carbohydrate placebo (28&amp;#x2009;g maltodextrose), while consuming their normal daily diet. Testing sessions included dietary analysis, lower-leg girth and body composition measurements, strength testing, and gastrocnemius muscle biopsies. Muscle was analyzed for mRNA expression of markers in the ubiquitin and calpain systems, myostatin, TNF-&amp;#x3b1;, and NF-&amp;#x3ba;B. Results. All genes of interest increased over time (P&amp;#x003C;.05), but there was no difference between groups.  Lower-leg girth decreased over time (P=0.02); however, there were no significant changes in body composition or strength. Conclusion. Short-term lower-limb disuse, despite the absence of significant muscle atrophy, is associated with increases in skeletal muscle gene expression of several proteolysis-related genes. These changes do not appear to be altered by oral PAA supplementation.</description><Author>Jennifer A. Bunn, Thomas W. Buford, Monica C. Serra, Richard B. Kreider, and Darryn S.

This proof-of-concept study tested whether a more potent and selective glucocorticoid receptor antagonist could block dietary-induced weight gain and increase insulin sensitivity in mice. Ten-week-old, male, C57BL/6J mice were fed a diet containing 60% fat calories and water supplemented with 11% sucrose for 4 weeks.  Groups (n=8) received one of the following: CORT 108297 (80&amp;#x2009;mg/kg QD), CORT 108297 (40&amp;#x2009;mg/kg BID), mifepristone (30&amp;#x2009;mg/kg BID), rosiglitazone (10&amp;#x2009;mg/kg QD), or vehicle. Compared to mice receiving a high-fat, high-sugar diet plus vehicle, mice receiving a high-fat, high-sugar diet plus either mifepristone or CORT 108297 gained significantly less weight.  At the end of the four week treatment period, mice receiving CORT 108297 40&amp;#x2009;mg/kg BID or CORT 108297 80&amp;#x2009;mg/kg QD also had significantly lower steady plasma glucose than mice receiving vehicle.  However, steady state plasma glucose after treatment was not highly correlated with reduced weight gain, suggesting that the effect of the glucocorticoid receptor antagonist on insulin sensitivity may be independent of its mitigating effect on weight gain.</description><Author>Tomoko Asagami, Joseph K.

Energy-dense foods are inconsistently implicated in elevated energy intake (EI).  This may stem from other food properties and/or differences in dietary incorporation, that is, as snacks or with meals. Objective. Assess intake pattern and food properties on acute appetitive ratings (AR) and EI. Design. 201 normal and overweight adults consuming a standard lunch. Test loads of 1255.2&amp;#x2009;kJ (300&amp;#x2009;kcal) were added to the lunch or provided as snack. Loads (peanuts, snack mix, and snack mix with peanuts) were energy, macronutrient, and volumetrically matched with a lunch portion as control. Participants completed meal and snack sessions of their randomly assigned load. Results. No differences were observed in daily EI or AR for meal versus snack or treatment versus control. Consumption of peanuts as a snack tended to strengthen dietary compensation compared to peanuts or other loads with a meal. Conclusions. Inclusion of an energy-dense food as a snack or meal component had comparable influence on AR and EI. Peanuts tended to elicit stronger dietary compensation when consumed as a snack versus with a meal. If substantiated, this latter observation suggests that properties other than those controlled here (energy, macronutrient content, and volume) modify AR and EI.</description><Author>A. A. Devitt, A.

The correlations were evaluated during 20&amp;#x2009;min of normal breathing (NB, control) and 20&amp;#x2009;min of paced breathing (PB) at 12 breaths&amp;#x22C5;min&amp;#x02212;1 (0.2&amp;#x2009;Hz). EE was not significantly correlated with any of the HRV variables before the metabolic challenge. After the challenge, EE was positively correlated with LF/HF and with VLF; VLF was also positively correlated with LF/HF during both NB and PB. These findings suggest that EE may be a correlate of LF/HF and of VLF spectral power of HRV in healthy adolescent/young adult males. The association of lower resting energy expenditure with lower amounts of VLF spectral power may occur in individuals with predilections for obese phenotypes.</description><Author>Richard M.

Filtration Rates in Healthy Young Adults: Results of a Clinical Trial</title><link>http://www.hindawi.com/journals/jnume/2011/146865/</link><description>Recently it has been reported that the estimated glomerular filtration rate (eGFR) is higher in habitual coffee consumers than in noncoffee consumers. However, the causality remains unclear. Therefore, we conducted a clinical trial to investigate the effects of coffee consumption on kidney function. Nineteen asymptomatic nonsmokers aged 21&amp;#8211;27 years old participated in this study. They consumed coffee (18&amp;#x2009;g coffee beans/450&amp;#x2009;mL per day) or green tea as a comparator for 2 weeks in a crossover design. Although creatinine-based eGFR was not affected after consuming either beverage, all cystatin-C-based eGFRs determined using five different equations were significantly increased after coffee consumption (means: 5.0&amp;#8211;7.7&amp;#37;), but not after green tea consumption (means: 0.1&amp;#8211;1.6&amp;#37;). Serum adiponectin and magnesium levels increased significantly after coffee consumption (means: 13.6&amp;#37; and 4.3&amp;#37;, resp.), but not after green tea consumption. These findings suggest that even a short period of coffee consumption may increase cystatin-C-based eGFR, along with favorable changes in serum adiponectin, in healthy young adults.</description><Author>Masafumi Saito, Tohru Nemoto, Satoshi Tobimatsu, Midori Ebata, Yulan Le, and Kei Nakajima</Author><copyright>Copyright &amp;#xa9; 2011 Masafumi Saito et al.

To investigate whether changes of meat consumption can affect body composition and laboratory parameters in healthy, normal weight, young women without the aim to reduce body weight. Research Design and Methods. Women volunteered to eat low-fat meat in addition to their habitual diet (M) or to exclude meat products from their diet (NOM). After 4 weeks M and NOM were crossed over between subjects. Changes in nutrient intake, morphometrics and plasma parameters were compared during M and NOM. Results. Daily protein intake (means &amp;#x00B1; SD) was 2.25 &amp;#x00B1; 0.35 (25.2&amp;#37; of energy) and 1.15 &amp;#x00B1; 0.26&amp;#x2009;g/kg (14.0&amp;#37; of energy) during M and NOM, respectively. Fat-free body mass (FFM) increased during M (0.7&amp;#x00B1;1.0&amp;#x2009;kg, P=.02) and decreased during NOM (-0.8&amp;#x00B1;0.8&amp;#x2009;kg, P=.003). Body fat mass was unchanged. Concentrations of total cholesterol (-7&amp;#37;), LDL-cholesterol (-8&amp;#37;), and glucose (-4&amp;#37;) deceased significantly after M. Fasting glutamine concentrations were decreased by M and increased by NOM. Conclusions. Additional meat intake can increase FFM without adverse effects on blood lipid concentrations. Long-term studies are required. Urinary excretion of 3-methylhistidine could represent a biomarker for meat protein consumption.</description><Author>Klaus J.

The magnitude and duration of postprandial blood glucose (PPG) elevations are important risk factors of diabetes and coronary heart diseases. Aim. To study PPG after ingestion of breads with and without pea fibre and rapeseed oil. Methods. After fasting overnight, 10 Pakistani immigrant women participated in three experiments having a crossover design and involving ingestion of various types of bread: regular coarse bread or fibre enriched-bread with two levels of rapeseed oil, all providing 25&amp;#x2009;g available carbohydrates (CHO). Blood glucose and satiety were determined before the meal and every 15 min over the next 2 hours. Results. Intake of an amount of pea fibre-enriched bread containing 25&amp;#x2009;g CHO attenuated, the postprandial peak glucose value, the incremental area under the glucose versus time curve during 15 to 75&amp;#x2009;min, and the glycemic profile, and increased duration of satiety (P&amp;#x003C;.05), as compared with intake of regular bread with 25&amp;#x2009;g carbohydrate. Conclusion. Pea fibre-enriched breads can reduce PPG and prolong satiety.</description><Author>Marianne S. H. Lunde, Victoria T. Hjellset, Gerd Holmboe-Ottesen, and Arne T.

Deficiency levels of 6&amp;#x2009;mg/L (34.2&amp;#x2009;&amp;#x003bc;M) for vitamin C and of 0.22&amp;#x2009;mg/L (0.4&amp;#x2009;&amp;#x003bc;M) for &amp;#x003b2;-carotene have been suggested below which cardiovascular risk might be increased. The present study performed on 897 presumably healthy subjects aged 40&amp;#x02013;60 years aimed to examine how modifiable lifestyle factors may be related to vitamin C and/or &amp;#x003b2;-carotene deficiency. Gender, smoking, lack of regular physical activity and of daily fruit consumption (&amp;#x02265;2/day), and social status (in particular, unemployment) were found to be significant risk factors for vitamin C deficiency. For &amp;#x003b2;-carotene deficiency, the same factors were identified except social status; moreover, overweight and OC use in women were also found to have a deleterious effect. For non exposed subjects, the probability of developing vitamin C deficiency was 4&amp;#x00025; in men and 2.4&amp;#x00025; in women. This probability increased to 66.3&amp;#x00025; for men and to 44.3&amp;#x00025; for women (and even to 50.4&amp;#x00025; under OC use), when all risk factors were present. For &amp;#x003b2;-carotene deficiency, the corresponding probabilities were equal to 29.7&amp;#x00025; in men and 13.7&amp;#x00025; in women (no risk factor present), and to 86.1&amp;#x00025; for men and 69.9&amp;#x00025; (91.6&amp;#x00025; for OC use) for women (all factors present), respectively.</description><Author>Jo&amp;#235;l Pincemail, Sophie Vanbelle, Fabien Degrune, Jean-Paul Cheramy-Bien, Corinne Charlier, Jean-Paul Chapelle, Didier Giet, George Collette, Adelin Albert, and Jean-Olivier Defraigne</Author><copyright>Copyright &amp;#xa9; 2011 Jo&amp;#xeb;l Pincemail et al.

Soybean meal is a natural source of isoflavones. The objective was to investigate the effects of feeding Synergy1 and SM on the incidence of azoxymethane- (AOM-) induced aberrant crypt foci (ACF) in Fisher 344 male rats. Rats (54) were randomly assigned to 9 groups (n=6). Control group (C) was fed AIN-93G and treatment groups Syn1 and SM at 5&amp;#37; and 10&amp;#37; singly and in combinations. Rats were injected with two s/c injections of AOM at 7 and 8 weeks of age at 16&amp;#x2009;mg/kg body weight and killed at 17 weeks by CO2 asphyxiation. Colonic ACF enumeration and hepatic enzyme activities were measured. Reductions (&amp;#37;) in total ACF among treatment groups fed combinations were higher (67&amp;#8211;77) compared to groups fed singly (52&amp;#8211;64). Synergistic mechanisms among phytochemicals may be responsible suggesting protective role in colon carcinogenesis with implications in food product development.</description><Author>V. P.

Current treatment modalities are very limited creating great interest for novel preventive and therapeutic options. Vitamin D seems to have a protective effect against pancreatic cancer by participating in numerous proapoptotic, antiangiogenic, anti-inflammatory, prodifferentiating, and immunomodulating mechanisms. 25-hydroxyvitamin D [25(OH)D] serum concentrations are currently the best indicator of vitamin D status. There are three main sources of vitamin D: sun exposure, diet,and dietary supplements. Sun exposure has been associated with lower incidence of pancreatic cancer in ecological studies.  Increased vitamin D levels seem to protect against pancreatic cancer, but caution is needed as excessive dietary intake may have opposite results. Future studies will verify the role of vitamin D in the prevention and therapy of pancreatic cancer and will lead to guidelines on adequate sun exposure and vitamin D dietary intake.</description><Author>Pubudu Bulathsinghala, Kostas N.

Dietary glycemic index (GI) has received considerable research interest over the past 25 years although its application to pregnancy outcomes is more recent. This paper critically evaluates the current evidence regarding the effect of dietary GI on maternal and fetal nutrition.
Methods. A systematic literature search using MEDLINE, EMBASE, CINAHL, Cochrane Library, SCOPUS, and ISI Web of Science, from 1980 through September 2010, was conducted. 
Results. Eight studies were included in the systematic review. Two interventional studies suggest that a low-GI diet can reduce the risk of large-for-gestational-age (LGA) infants in healthy pregnancies, but one epidemiological study reported an increase in small-for-gestational-age (SGA) infants. Evidence in pregnancies complicated by gestational diabetes mellitus (GDM), though limited (n=3), consistently supports the advantages of a low-GI diet.
Conclusion. There is insufficient evidence to recommend a low-GI diet during normal pregnancy. In pregnancy complicated by GDM, a low-GI diet may reduce the need for insulin without adverse effects on pregnancy outcomes. Until larger-scale intervention trials are completed, a low-GI diet should not replace the current recommended pregnancy diets from government and health agencies. Further research regarding the optimal time to start a low-GI diet for maximum protection against adverse pregnancy outcomes is warranted.</description><Author>Jimmy Chun Yu Louie, Jennie C.

To evaluate glucose and insulin profiles in adolescents with mild stunting and overweight in order to assess the possibility of increased predisposition to diabetes. Subjects and Methods. The study population consisted of 66 pubertal adolescents classified as mildly stunted (height-for-age z scores &amp;#x2265;&amp;#x2212;2 and &amp;#x003C;&amp;#x2212;1) or of normal stature, as well as overweight (body mass index &amp;#x02265;85th percentile) or normal weight. Beta-cell function and insulin resistance were evaluated according to the homeostasis model assessment (HOMA). Results. In the group with mild stunting, glucose, insulin, and HOMA-IR levels were significantly higher in overweight adolescents compared with those of normal weight, whereas HOMA-B levels were significantly lower. Adolescents with mild stunting showed significantly higher accumulations of body and abdominal fat than their normal stature counterparts. Conclusions. The presence of mild stunting was associated with higher levels of glucose and insulin, diminished function of beta cells, and increased insulin resistance. These results reinforce the need for intervention in adolescents with mild stunting.</description><Author>Carla Danusa da Luz Santos, Ana Paula Grotti Clemente, Vinicius Jos&amp;#233; Baccin Martins, Maria Paula Albuquerque, and Ana Lydia Sawaya</Author><copyright>Copyright &amp;#xa9; 2010 Carla Danusa da Luz Santos et al.

The Diet-Induced Obesity (DIO) rat model was used to investigate CFE&amp;#39;s anorexigenic effects. Rats were randomly divided into three groups: (i) untreated control (C), (ii) control for cafeteria diet (CA), and (iii) cafeteria diet fed + CFE treated.  Rats in the test group received cafeteria diet and CFE from day one onwards.  CFE was administered by gavage at three doses (25, 50, 100&amp;#x2009;mg/Kg&amp;#x2009;BW per day) for 90 days.  The antiobesogenic effects of CFE were evaluated by monitoring changes in feed intake, body weight, serum lipid and hormonal (leptin) profiles, fat pads, and liver weight.  Antiatherosclerotic effects were measured by histology.  CFE induced significant and dose-dependent inhibition of food intake, with dose-related prevention of gains in body weight, liver weight, and fat pad mass.  Alterations in serum lipid profiles associated with weight gain were similarly inhibited, as were the typical increases in serum leptin levels.  These data substantiate CFE&amp;#39;s reported anorexigenic effects.  CFE treatment also conferred protection against atherogenesis.  We conclude that CFE possesses antiobesogenic and antiatherosclerotic properties.</description><Author>Soundararajan Kamalakkannan, Ramaswamy Rajendran, Ramasamy V.

Therefore, we selected thirteen frequently consumed species of Polish mushrooms and determined the concentration of polyphenols, flavonoids, &amp;#x03B2;-carotene, and lycopene in aqueous and methanolic extracts of dried fruiting bodies as well as their reducing power and ability to scavenge ABTS cation radical.
We found that the concentration of antioxidants is different in different species and in various parts of the fruiting body of mushrooms. We observed a strong correlation (r&amp;#x003E;0.9) between the concentration of total phenolics and reducing power/scavenging effects in both aqueous and methanolic extracts, while this correlation was moderate for flavonoids. Beta-carotene did not contribute discernibly to the antioxidative properties of the extracts, while lycopene had a significant contribution to the scavenging activity of methanolic mushroom extracts.</description><Author>A.

The liver plays a crucial role in the regulation of nutrition by trafficking the metabolism of nutrients, their distribution and appropriate use by the body. Nutritional consequences with the potential to cause nervous system dysfunction occur in liver failure, and many factors contribute to malnutrition in hepatic failure. Among them are inadequate dietary intake, malabsorption, increased protein losses, hypermetabolism, insulin resistance, gastrointestinal bleeding, ascites, inflammation/infection, and hyponatremia. Patients at risk of malnutrition are relatively difficult to identify since liver disease may interfere with biomarkers of malnutrition. The supplementation of the diet with amino acids, antioxidants, vitamins as well as probiotics in addition to meeting energy and protein requirements may improve nutritional status, liver function, and hepatic encephalopathy in patients with end-stage liver failure.</description><Author>Chantal B&amp;#233;meur, Paul Desjardins, and Roger F.
