Ramadan fasting following laparoscopic sleeve gastrectomy: a prospective online survey cohort study in Egypt.

Purpose: This study aims to explore the feasibility and implications of Ramadan fasting for patients who have undergone laparoscopic sleeve gastrectomy (LSG), assessing impacts on hydration, nutrient intake, weight management, and gastrointestinal symptoms. Methods: A prospective online survey was conducted among 218 LSG patients and 83 control individuals with obesity who had not undergone surgery. Participants were surveyed before and after Ramadan, providing data on fasting practices, hunger and satiety levels, fluid and nutrient intake, and the occurrence of gastrointestinal symptoms. Statistical analysis was used to compare outcomes between fasting and non-fasting periods and between LSG patients and control participants. Results: A total of 70.2% of LSG patients completed the entire month of Ramadan fasting, with a significant correlation found between the duration post-surgery and the ability to fast. Fasting LSG patients reported decreased hunger, increased satiety, and significant reductions in fluid and nutrient intake during Ramadan. Weight loss was reported in 90.8% of fasting patients, with an average total weight loss of 7.2%. Gastrointestinal symptoms were mild and manageable. Conclusion: The majority of LSG patients can successfully fast during Ramadan with appropriate precautions, including adequate fluid and protein intake. The study highlights the need for patient education and tailored nutritional guidance to ensure safe and effective fasting post-LSG. In order to fast for the entire month, patients may be advised to consider postponing surgery for a few months after Ramadan, avoid overeating during non-fasting hours, and ensure sufficient fluid consumption and protein intake during fasting.

Adhesión a la dieta mediterránea y conducta alimentaria en escolares españoles / Adherence to the Mediterranean diet and eating behaviour in Spanish schoolchildren

Introducción: las conductas alimentarias pueden modular o influir en la calidad de la dieta y el grado de adherencia a la dieta mediterráneade niños y adolescentes.Objetivos: investigar la asociación entre la calidad de la dieta y el comportamiento alimentario en un grupo de escolares españoles.Métodos: se trata de un estudio transversal descriptivo en una muestra de 283 escolares españoles de seis a 16 años. Cada sujeto fue evaluadomediante el cuestionario KIDMED de adherencia a la dieta mediterránea y el cuestionario Children’s Eating Behaviour Questionnaire (CEBQ) paraevaluar el comportamiento alimentario.Resultados: un 12,80 % de la muestra presentó baja adherencia a la dieta mediterránea; un 59,80 %, adherencia mejorable; y un 27,40 %,adherencia alta. Al relacionar las conductas alimentarias con la calidad dietética, los escolares con mayor disfrute por los alimentos y menosexigencia con la comida presentan el doble de adherencia a la dieta mediterránea, por un consumo de casi el doble de vegetales, frutos secoso pescado, así como menor ingesta de procesados de baja calidad (golosinas y dulces). La respuesta a la saciedad y la velocidad de ingestatambién tuvieron un papel importante en las elecciones alimentarias.Conclusiones: las conductas alimentarias pueden tener un importante papel en la calidad de la dieta de los escolares, destacando el disfrute y laaceptación o rechazo por los alimentos. Dada la naturaleza bidireccional de los efectos entre las conductas alimentarias y la calidad de la dieta, elanálisis conjunto puede ser la base de futuras investigaciones con el objetivo de un mejor abordaje nutricional desde las edades más tempranas.(AU)

Introduction: eating behaviors may modulate or influence diet quality and the degree of adherence to the Mediterranean diet in children andadolescents.Aims: to investigate the association between diet quality and eating behavior in a group of Spanish schoolchildren.Methods: descriptive cross-sectional study of 283 Spain schoolchildren aged six to 16. Each subject was assessed using the KIDMED question-naire for adherence to the Mediterranean diet and the Children’s Eating Behaviour Questionnaire (CEBQ) questionnaire to assess eating behavior.Results: of the sample, 12.80 % had low adherence to the Mediterranean diet, 59.80 % had poor adherence, 59.80 % could be improved, and27.40 % had high adherence. When relating eating behavior to dietary quality, it was found that, generally, schoolchildren with greater enjoymentof food and less demand for food have double the adherence to the Mediterranean diet due to almost twice the consumption of vegetables,nuts, and fish, and a lower intake of low-quality processed foods (sweets). The response to satiety and the speed of ingestion also played animportant role in food choices.Conclusions: eating behaviors may play an essential role in the quality of school children’s diets highlighting the enjoyment and acceptance orrejection of food. Given the bidirectional nature of the effects between eating behaviors and diet quality, the joint analysis may be the basis forfuture research with the aim of a better nutritional approach from the earliest ages.(AU)

Glycemic and Satiety Response to Three Mexican Honey Varieties.

Honey is considered one of the last untreated natural food substances, with a complex composition. It is produced by bees (Apis mellifera) from nectar. The glycemic index (GI) is a physiological assessment of a food's carbohydrate content via its effect on postprandial blood glucose concentrations. This study evaluated the GI and the satiety response to three Mexican types of honey administered to 26 healthy volunteers. The fructose values ranged from 272.40 g/kg to 395.10 g/kg, while the glucose value ranged from 232.20 g/kg to 355.50 g/kg. The fructose/glucose (F/G) ratio of honey was 1.45, 1.00, and 1.17 for highland, multifloral, and avocado honey, respectively. Highland and avocado honey were classified as medium-GI (69.20 ± 4.07 and 66.36 ± 5.74, respectively), while multifloral honey was classified as high-GI (74.24 ± 5.98). Highland honey presented a higher satiety values response than glucose. The difference in GI values and the satiety response effect of highland honey could be explained by its different carbohydrate composition and the possible presence of other honey components such as phytochemicals. Honey, especially avocado, could therefore be used as a sweetener without altering significantly the blood glucose concentration.

Eating Behavior and Obesity in a Sample of Spanish Schoolchildren.

From the point of view of prevention, it is convenient to explore the association between eating behavior and the obese phenotype during school and adolescent age. The aim of the present study was to identify eating behavior patterns associated with nutritional status in Spanish schoolchildren. A cross-sectional study of 283 boys and girls (aged 6 to 16 years) was carried out. The sample was evaluated anthropometrically by Body Mass Index (BMI), waist-to-height ratio (WHtR) and body fat percentage (%BF). Eating behavior was analyzed using the CEBQ "Children's Eating Behavior Questionnaire". The subscales of the CEBQ were significantly associated with BMI, WHtR and %BF. Pro-intake subscales (enjoyment of food, food responsiveness, emotional overeating, desire for drinks) were positively related to excess weight by BMI (ß = 0.812 to 0.869; p = 0.002 to <0.001), abdominal obesity (ß = 0.543-0.640; p = 0.02 to <0.009) and high adiposity (ß = 0.508 to 0.595; p = 0.037 to 0.01). Anti-intake subscales (satiety responsiveness, slowness in eating, food fussiness) were negatively related to BMI (ß = -0.661 to -0.719; p = 0.009 to 0.006) and % BF (ß = -0.17 to -0.46; p = 0.042 to p = 0.016).

Impact of a prenatal education intervention in pregnant women to prevent overweight in infants.

INTRODUCTION: During the first 1000 days of life is the basis for a child's future health established. OBJECTIVE: To evaluate the impact of a prenatal educational intervention in pregnant women on the nutritional status of the child from birth to 4 months of age. METHODS: Quasi-experimental intervention design in women with at least 12 weeks of gestation, who were randomly assigned to an intervention group (IG) to participate in five group and three individual sessions on feeding practices and maternal perception of the child's weight and signals of hunger-satiety; the control group (CG) received routine care that included at least three prenatal consultations. RESULTS: Thirty women were included in each group. After the intervention, women in the CG practiced less exclusive breastfeeding, were more likely to underestimate or overestimate the children's weight, and perceived hunger-satiety signals with less intensity (p < 0.05). 80 % of the infants in the IG had normal weight, whereas 63 % of those in the CG had a combination of overweight and obesity (p < 0.05). CONCLUSIONS: The prenatal education program in pregnant women showed a significant effect on postnatal nutritional status of infants four months after birth.

INTRODUCCIÓN: Durante los primeros 1000 días de vida se establece la base para la salud futura de un niño. OBJETIVO: Evaluar el impacto de una intervención educativa prenatal en mujeres embarazadas sobre el estado nutricional del hijo desde el nacimiento hasta los cuatro meses de edad. MÉTODOS: Diseño cuasiexperimental de intervención con mujeres a partir de la semana 12 de gestación, asignadas aleatoriamente a un grupo de intervención (GI) para recibir cinco sesiones grupales y tres individuales sobre prácticas de alimentación y percepción materna del peso del hijo y de señales de hambre-saciedad; el grupo control (GC) recibió atención de rutina que incluía al menos tres consultas prenatales. RESULTADOS: 30 mujeres conformaron cada grupo. Después de la intervención, las mujeres del GC practicaron menos lactancia materna exclusiva, fueron propensas a subestimar o sobrestimar el peso del hijo y percibieron con menor intensidad las señales de hambre-saciedad (p < 0.05). El 80 % de los lactantes del GI presentaron peso normal y 63 % de los niños del GC, una combinación de sobrepeso y obesidad (p < 0.05). CONCLUSIONES: El programa de educación prenatal en mujeres embarazadas mostró un efecto significativo en el estado nutricional de los lactantes después de cuatro meses del nacimiento.

Nutrient composition of mealtimes and its association with the energy intake of subsequent meals among Mexican adults.

The composition of the diet influences energy intake by affecting satiety. Macronutrients have a hierarchical effect on satiety, where proteins have the greatest influence, followed by carbohydrates and fats. Alcohol consumption has also shown an effect on increasing energy intake in subsequent meals. Most of this evidence comes from studies under controlled conditions but, it is not clear if effects of diet composition are maintained or counteracted by other determinants of EI in real life. In this paper, we described the diet composition by mealtime in a sample of free-living Mexican adults, as well as evaluated its association with the energy intake in subsequent meals between- and within-subjects. We used information from a national cross-sectional survey of the urban Mexican population. Dietary information was collected by an automated multiple-pass 24-h recall and all participants had information from three non-consecutive days (two weekdays and one weekend). We analyzed information from adults from 20 years and older and used mixed-effects hybrid models that isolate the intra-subject, from the between-subject associations using a substitution approach. We found that alcohol and added sugars were associated with an increased EI between- and within-subjects, while fiber was associated with a decreased EI in subsequent meals within-subjects. Between-subjects, the higher intake of proteins was associated with a decrease in EI, whereas carbohydrates were associated with an increased EI in subsequent meals. We concluded that the composition of the diet at one mealtime predicted EI in subsequent meals of free-living subjects. Understanding the effects of diet composition could guide strategies to reduce EI and obesity prevention.

Acacia Gum Is Well Tolerated While Increasing Satiety and Lowering Peak Blood Glucose Response in Healthy Human Subjects.

Acacia gum (AG) is a non-viscous soluble fiber that is easily incorporated into beverages and foods. To determine its physiological effects in healthy human subjects, we fed 0, 20, and 40 g of acacia gum in orange juice along with a bagel and cream cheese after a 12 h fast and compared satiety, glycemic response, gastrointestinal tolerance, and food intake among treatments. Subjects (n = 48) reported less hunger and greater fullness at 15 min (p = 0.019 and 0.003, respectively) and 240 min (p = 0.036 and 0.05, respectively) after breakfast with the 40 g fiber treatment. They also reported being more satisfied at 15 min (p = 0.011) and less hungry with the 40 g fiber treatment at 30 min (p = 0.012). Subjects reported more bloating, flatulence, and GI rumbling on the 40 g fiber treatment compared to control, although values for GI tolerance were all low with AG treatment. No significant differences were found in area under the curve (AUC) or change from baseline for blood glucose response, although actual blood glucose with 20 g fiber at 30 min was significantly less than control. Individuals varied greatly in their postprandial glucose response to all treatments. AG improves satiety response and may lower peak glucose response at certain timepoints, and it is well tolerated in healthy human subjects. AG can be added to beverages and foods in doses that can help meet fiber recommendations.

Probiotics have minimal effects on appetite-related hormones in overweight or obese individuals: A systematic review of randomized controlled trials.

BACKGROUND & AIMS: Overweight and obese individuals show changes in mechanisms related to appetite due to several factors, including excess fat and gut microbiota imbalance. Probiotics have been presented as a strategy for modulating gut microbiota and regulating these mechanisms. The aim of this systematic review was to assess the effects of probiotics on appetite-related hormones in overweight or obese individuals. METHODS: A systematic review of randomized controlled trials was performed in nine electronic databases (Pubmed, Scopus, Web of Science, Cochrane Controlled Register of Trials, ProQuest Dissertations and Theses, PsycINFO, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov and Open Grey) and in a manual search of studies until March 20, 2020. The risk of bias of each study was appraised using the RoB 2.0 tool. All research stages were carefully based on PRISMA recommendations. RESULTS: Twenty-four studies (1587 participants) were included in this systematic review. The outcomes related to appetite assessed in the included studies were: leptin, insulin, adiponectin, resistin, nesfatin-1, adropin, omentin-1, GLP-1, GLP-2 and glucagon. Compared to the control group after supplementation, four studies involving 272 participants reported statistically significant reduction in fasting insulin. On the other hand, one study involving 56 participants reported statistically significant increase in adropin and omentin-1. CONCLUSIONS: Probiotics have minimal effects on appetite-related hormones in overweight or obese individuals. However, knowledge in this area is progressing and further studies with a low risk of bias may help to clarify the role of probiotics in appetite control.

Effects of Saccharin Consumption on Operant Responding for Sugar Reward and Incubation of Sugar Craving in Rats.

Repeated experience with artificial sweeteners increases food consumption and body weight gain in rats. Saccharin consumption may reduce the conditioned satiety response to sweet-tasting food. Rats were trained to press a lever to obtain sucrose for five days. A compound cue (tone + light) was presented with every sucrose delivery. On the following day, each lever press produced only the compound cue (cue-reactivity test). Subjects were then provided with yogurt for three weeks in their home cages. The rats were divided into two groups. Rats in the saccharin group received yogurt sweetened with saccharin on some days and unsweetened yogurt on others. For the plain group, only unsweetened plain yogurt was provided. Subsequently, the cue-reactivity test was conducted again. On the following day, the rats underwent a consumption test in which each lever press was reinforced with sucrose. Chow consumption and body weight gain were larger in the saccharin group than in the plain group. Lever responses increased from the first to the second cue-reactivity tests (incubation of craving) in both groups. During the consumption test, lever responses were higher in the saccharin group than in the plain group, suggesting that the conditioned satiety response was impaired in the saccharin group.

Dietary protein and appetite sensations in individuals with overweight and obesity: a systematic review.

PURPOSE: This systematic review aimed to synthesize the available evidence on the effects of a high-protein diet on appetite sensations in individuals with overweight and obesity. METHODS: Two authors independently conducted literature searches, study selection, design of the method, and quality appraisal. The main inclusion criteria were studies involving protocols that present a protein intake greater than 1.2 g/kg/day or 25% of the total daily energy content compared to a normal protein diet, i.e., 0.8-1.2 g/kg/day or 15%-20% of the total energy content. Studies that evaluated test meals or diet within a period of less than 7 days and participants with diabetes, cancer, or other specific conditions were excluded from this review. The literature search was updated until November 2019 using the main databases available. RESULTS: Of a total of 4191 records, ten articles met the inclusion criteria and included a total of 1079 subjects. In six studies, participants experienced enhanced fullness or satiety in response to a high-dietary protein intake, of which four studies had an intervention period of 10-12 weeks. CONCLUSION: Our results suggest that among individuals with overweight or obesity, higher dietary protein intake may influence appetite sensations by enhancing fullness or satiety. The low level of evidence, due to the heterogeneity of the protocols and the high risk of bias, highlights the need for further studies to confirm these results.

Trypsin inhibitors: promising candidate satietogenic proteins as complementary treatment for obesity and metabolic disorders?

The increase in non-communicable chronic diseases has aroused interest in the research of adjuvants to the classic forms of treatments. Obesity and metabolic syndrome are the main targets of confrontation because they relate directly to other chronic diseases. In this context, trypsin inhibitors, molecules with wide heterologous application, appear as possibilities in the treatment of overweight and obesity due to the action on satiety related mechanisms, mainly in the modulation of satiety hormones, such as cholecystokinin. In addition, trypsin inhibitors have the ability to also act on some biochemical parameters related to these diseases, thus, emerging as potential candidates and promising molecules in the treatment of the obesity and metabolic syndrome. Thus, the present article proposes to approach, through a systematic literature review, the advantages, disadvantages and viabilities for the use of trypsin inhibitors directed to the treatment of overweight and obesity.

Perception of Hunger/Satiety and Nutrient Intake in Women Who Regain Weight in the Postoperative Period After Bariatric Surgery.

OBJECTIVE: To investigate the perception of hunger and satiety and its association with nutrient intake in women who regain weight in the postoperative period after bariatric surgery. METHODS: Cross-sectional study of adult women divided into three groups: weight regain (n = 20), stable weight (n = 20) (both at least 24 months after Roux-en-Y gastric bypass surgery), and non-operated obesity (n = 20). A visual analogue scale measured hunger/satiety perception while fasting, immediately after finishing a test meal, and 180 min after finishing the test meal. The incremental area above or under the curve was calculated. Food intake was analyzed by 3 days of food recall and adjusted for intraindividual variation. To make between-group comparisons, Mann-Whitney, ANOVA, Kruskal-Wallis, and independent-samples T tests and Pearson's correlation were used. RESULTS: There were no between-group differences in incremental areas of hunger/satiety, but protein intake was significantly lower among patients who regained weight compared with those who had stable body weight (0.99 ± 0.23 g/kg body weight vs. 1.17 ± 0.21 g/kg body weight, p = 0.047). In the group that regained weight, satiety was correlated positively with usual dietary protein density (r = 0.541; p = 0.017) and negatively with usual carbohydrate intake (r = - 0.663; p = 0.002). CONCLUSION: Women who regained weight presented similar perceptions of hunger/satiety to those of patients without weight regain and with non-operated obesity. In patients who regained weight postoperatively, satiety perception was correlated positively with usual dietary protein density and inversely with usual carbohydrate intake.

Acute Epigallocatechin 3 Gallate (EGCG) Supplementation Delays Gastric Emptying in Healthy Women: A Randomized, Double-Blind, Placebo-Controlled Crossover Study.

Background: Epigallocatechin 3 Gallate (EGCG) appears to act in appetite control through hormonal modulation. However, there is a lack of elucidation of EGCG's action mechanisms, especially in humans. The aim of this study was to evaluate the effects of acute EGCG supplementation on gastric emptying and its relation to blood hormones, glucose and appetite perceptions in healthy women. Methods: 22 healthy adult women were included in a randomized, double-blind, placebo-controlled crossover study. On two separate occasions, 1 week apart from each other, we offered 800 mg of corn starch (placebo) or 752 mg of EGCG. Appetite was assessed through gastric emptying; perceptions of hunger, desire to eat and satiation; and plasma insulin, adiponectin, leptin and glucose concentrations. The evaluations were carried out in fasting, 30, 90 and 150 min after supplementation. Results: EGCG supplementation induced higher relative gastric volume at 30 and 90 min. Satiation at 90 min was higher in the EGCG group. Adiponectin concentrations at 150 min were higher with EGCG, but no difference was found for glucose, insulin and leptin concentrations. Conclusions: Acute EGCG supplementation is able to delay gastric emptying in healthy women to a small, but statistically significant extent. This study was registered at the Brazilian Registry of Clinical Trials (ReBEC) as RBR-9svwrv.

Impact of three different plate colours on short-term satiety and energy intake: a randomized controlled trial.

BACKGROUND: Plate colour was previously shown to alter the amount of food consumption due to its environmental effect on food intake. However, different studies have indicated that the effect of plate colour cannot be generalized. In light of this finding, the main objective of this study was to determine whether food consumption during an open buffet meal was different when using same-sized white, red or black plates. METHODS: This study was a crossover study conducted with 54 female participants aged 18-30 years with normal BMIs. On experimental days, participants ate a standard breakfast and were then randomly assigned to eat ad libitum lunch (pasta with tomato sauce and soft drinks) using white, red or black plates. Visual analogue scale (VAS) scores on satiety outcomes were measured for all meals. Energy and macronutrient intake during lunch was recorded. RESULTS: The results showed that plate colour exerted a significant effect on food intake during the test days (p = 0.021). The average total energy intake with red (1102.16 ± 47.12 kcal, p = 0.05) and black plates (1113.19 ± 47.12 kcal, p = 0.034) was significantly increased when compared to that with white plates (945.72 ± 47.12 kcal). There were no differences between red and black plates (p = 0.985). Overall, mean VAS scores did not indicate a significant difference between the groups. CONCLUSIONS: Plate colour may be a crucial determinant of energy intake.

Glucagon-Like Peptides 1 and 2 Are Involved in Satiety Modulation After Modified Biliopancreatic Diversion: Results of a Pilot Study.

BACKGROUND: This paper aimed to evaluate the influence of modified biliopancreatic diversion (BPD) on the levels of GLP-1 and GLP-2 and correlate them with satiety regulation. METHODS: This is a pilot prospective cohort study that evaluated six mildly obese individuals with type 2 diabetes mellitus, which underwent modified BPD and were followed-up for 12 months. Levels of GLP-1 and GLP-2 after a standard meal tolerance test were determined and correlated with satiety scores obtained by means of a visual analogue scale (VAS). RESULTS: There were significant changes in BMI (33 ± 2.2 versus 26.3 ± 2.2 kg/m2; p < 0.001), HbA1c (7.9 ± 1.6 versus 5.8 ± 1.2%; p = 0.026), total cholesterol (172.3 ± 11.1 versus 134.7 ± 16.1 mg/dL; p < 0.001), LDL-c (103.3 ± 13 versus 64.6 ± 12.2 mg/dL; p < 0.001), and postprandial GLP-2 (972.7 ± 326.2 versus 1993.2 ± 1024.7; p = 0. 044). None of the scores obtained in the VAS significantly changed after surgery. After surgery, there were significant correlations of VAS scores and GLP-1 levels in question 01 ("how hungry do you feel?"; R = -0.928; p = .008) and GLP-2 levels in questions 02 ("how full do you feel?" R = 0.943; p = 0.005) and 04 ("how much do you think you can eat now? R = -0.829; p = 0.042). CONCLUSIONS: Modified BPD does not lead to significant changes in satiety evaluated by the VAS; different aspects of satiety regulation are correlated with the postprandial levels of GLP-1 (hunger feeling) and GLP-2 (satiation feeling and desire to eat) 1 year after modified BPD, signaling a specific postoperative gut hormone-related modulation of appetite.

Chia seed (Salvia Hispanica L.) added yogurt reduces short-term food intake and increases satiety: randomised controlled trial.

BACKGROUND/OBJECTIVES: Several studies have reported that consumption of Salvia Hispanica L.,commonly known as chia seed, may exert beneficial effects on health outcomes. The main purpose of this study was to examine the influence of chia seed consumption as a mid-morning snack on short-term satiety. SUBJECTS/METHODS: Subjects (n = 24) were tested using a randomized, cross-over design consisting of three mid-morning snacks. Yogurt with no chia seed, yogurt with 7 g chia seed, and yogurt with 14 g chia seed were given to subjects on different test days. After subjects were asked to report visual analog scale (VAS) scores on sensory outcomes, ad libitum lunch was served, and energy intake of individuals was measured. RESULTS: VAS scores indicated that participants reported significantly lower scores for hunger (P = 0.033), prospective food consumption (P = 0.031), amounts of food that could be consumed (P = 0.017), desire for sugary foods (P = 0.015), and higher scores for satiety (P = 0.031) on the test days with 7 g and 14 g chia seed. Energy intake of individuals during ad libitum lunch was significantly lower when they consumed yogurt with 7 g or 14 g chia seed (P = 0.037). CONCLUSIONS: The study demonstrated that chia seed consumption as a mid-morning snack may induce short-term satiety in healthy individuals.

Saciación vs saciedad: reguladores del consumo alimentario / Satiation and satiety in the regulation of energy intake

The study of the factors that regulate high energy food intake is especially relevant nowadays due to the high prevalence of overweight and obesity. Food intake regulation can be divided in two basic processes, namely satiation and satiety. Satiation is the process that determines the moment in which feeding stops and regulates the amount of ingested food during a single meal. Satiety is the interval between meals and regulates the time elapsed between two meals. The longer the interval, the lower energy intake. Each of these processes are regulated by different factors, which are here reviewed.

Modification of appetite by bread consumption: A systematic review of randomized controlled trials.

The inclusion of different ingredients or the use of different baking technologies may modify the satiety response to bread, and aid in the control of food intake. The aim of this study was to perform a systematic search of randomized clinical trials on the effect of bread consumption on appetite ratings in humans. The search equation was ("Bread"[MeSH]) AND ("Satiation"[MeSH] OR "Satiety response"[MeSH]), and the filter "clinical trials." As a result of this procedure, 37 publications were selected. The satiety response was considered as the primary outcome. The studies were classified as follows: breads differing in their flour composition, breads differing in ingredients other than flours, breads with added organic acids, or breads made using different baking technologies. In addition, we have revised the data related to the influence of bread on glycemic index, insulinemic index and postprandial gastrointestinal hormones responses. The inclusion of appropriate ingredients such as fiber, proteins, legumes, seaweeds and acids into breads and the use of specific technologies may result in the development of healthier breads that increase satiety and satiation, which may aid in the control of weight gain and benefit postprandial glycemia. However, more well-designed randomized control trials are required to reach final conclusions.
