Sensory and physical characteristics of foods that impact food intake without affecting acceptability: Systematic review and meta-analyses.

ABSTRACT: This systematic review with meta-analyses aimed to identify the sensory and physical characteristics of foods/beverages which increase satiation and/or decrease/delay subsequent consumption without affecting acceptability. Systematic searches were first undertaken to identify review articles investigating the effects of any sensory and physical food characteristic on food intake. These articles provided some evidence that various textural parameters (aeration, hardness, homogeneity, viscosity, physical form, added water) can impact food intake. Individual studies investigating these effects while also investigating acceptability were then assessed. Thirty-seven individual studies investigated a textural manipulation and provided results on food intake and acceptability, 13 studies (27 comparisons, 898 participants) investigated effects on satiation, and 29 studies (54 comparisons, 916 participants) investigated effects on subsequent intake. Meta-analyses of within-subjects comparisons (random-effects models) demonstrated greater satiation (less weight consumed) from food products that were harder, chunkier, more viscous, voluminous, and/or solid, while demonstrating no effects on acceptability. Textural parameters had limited effects on subsequent consumption. Between-subjects studies and sensitivity analyses confirmed these results. These findings provide some evidence that textural parameters can increase satiation without affecting acceptability. The development of harder, chunkier, more viscous, voluminous, and/or solid food/beverage products may be of value in reducing overconsumption.

Project description:BackgroundVoice-based systems such as Amazon Alexa may be useful for collecting self-reported information in real time from participants of epidemiology studies using verbal input. In epidemiological research studies, self-reported data tend to be collected using short, infrequent questionnaires, in which the items require participants to select from predefined options, which may lead to errors in the information collected and lack of coverage. Voice-based systems give the potential to collect self-reported information "continuously" over several days or weeks. At present, to the best of our knowledge, voice-based systems have not been used or evaluated for collecting epidemiological data.ObjectiveWe aimed to demonstrate the technical feasibility of using Alexa to collect information from participants, investigate participant acceptability, and provide an initial evaluation of the validity of the collected data. We used food and drink information as an exemplar.MethodsWe recruited 45 staff members and students at the University of Bristol (United Kingdom). Participants were asked to tell Alexa what they ate or drank for 7 days and to also submit this information using a web-based form. Questionnaires asked for basic demographic information, about their experience during the study, and the acceptability of using Alexa.ResultsOf the 37 participants with valid data, most (n=30, 81%) were aged 20 to 39 years and 23 (62%) were female. Across 29 participants with Alexa and web entries corresponding to the same intake event, 60.1% (357/588) of Alexa entries contained the same food and drink information as the corresponding web entry. Most participants reported that Alexa interjected, and this was worse when entering the food and drink information (17/35, 49% of participants said this happened often; 1/35, 3% said this happened always) than when entering the event date and time (6/35, 17% of participants said this happened often; 1/35, 3% said this happened always). Most (28/35, 80%) said they would be happy to use a voice-controlled system for future research.ConclusionsAlthough there were some issues interacting with the Alexa skill, largely because of its conversational nature and because Alexa interjected if there was a pause in speech, participants were mostly willing to participate in future research studies using Alexa. More studies are needed, especially to trial less conversational interfaces.

Project description:Consumption of a cholesterol lowering dietary portfolio including plant sterols (PS), viscous fibre, soy proteins and nuts for 6 months improves blood lipid profile. Plant sterols reduce blood cholesterol by inhibiting intestinal cholesterol absorption and concerns have been raised whether PS consumption reduces fat soluble vitamin absorption.The objective was to determine effects of consumption of a cholesterol lowering dietary portfolio on circulating concentrations of PS and fat soluble vitamins.Using a parallel design study, 351 hyperlipidemic participants from 4 centres across Canada were randomized to 1 of 3 groups. Participants followed dietary advice with control or portfolio diet. Participants on routine and intensive portfolio involved 2 and 7 clinic visits, respectively, over 6 months.No changes in plasma concentrations of ? and ? tocopherol, lutein, lycopene and retinol, but decreased ?-carotene concentrations were observed with intensive (week 12: p?=?0.045; week 24: p?=?0.039) and routine (week 12: p?=?0.031; week 24: p?=?0.078) portfolio groups compared to control. However, cholesterol adjusted ?-carotene and fat soluble compound concentrations were not different compared to control. Plasma PS concentrations were increased with intensive (campesterol:p?=?0.012; ?-sitosterol:p?=?0.035) and routine (campesterol: p?=?0.034; ?-sitosterol: p?=?0.080) portfolio groups compared to control. Plasma cholesterol-adjusted campesterol and ?-sitosterol concentrations were negatively correlated (p?<?0.001) with total and LDL-C levels.Results demonstrate that consuming a portfolio diet reduces serum total and LDL-C levels while increasing PS values, without altering fat soluble compounds concentrations. The extent of increments of PS with the current study are not deleterious and also maintaining optimum levels of fat soluble vitamins are of paramount necessity to maintain overall metabolism and health. Results indicate portfolio diet as one of the best options for CVD risk reduction.clinicaltrials.gov Identifier: NCT00438425.

Project description:Secreted proteins of the C1q/TNF-related protein (CTRP) family play diverse functions in different organ systems. In the brain, CTRP14/C1QL1 is required for the proper establishment and maintenance of synapses between climbing fibers and cerebellar Purkinje cells. Beyond the central nervous system, the function of CTRP14 is largely unknown. A recent genome-wide association study has implicated CTRP14/C1QL1 as a candidate gene associated with total body fat mass. Here, we explored the potential metabolic roles of CTRP14. We show that Ctrp14 expression in peripheral tissues is dynamically regulated by fasting-refeeding and high-fat feeding. In the chow-fed basal state, Ctrp14 deletion modestly reduces glucose tolerance in knockout (KO) male mice and affects physical activity in a sex- and nutritional state-dependent manner. In the ad libitum fed state, Ctrp14 KO male mice have lower physical activity. In contrast, female KO mice have increased physical activity in the fasted and refed states. In response to an obesogenic diet, CTRP14-deficient mice of either sex gained similar weight and are indistinguishable from wild-type littermates in body composition, lipid profiles, and insulin sensitivity. Ambulatory activity, however, is reduced in Ctrp14 KO male mice. Food intake is also reduced in Ctrp14 KO male mice in the refed period following food deprivation. Meal pattern analyses indicate that decreased caloric intake from fasting to refeeding is due, in part, to smaller meal size. We conclude that CTRP14 is largely dispensable for metabolic homeostasis, but highlight context-dependent and sexually dimorphic metabolic responses of Ctrp14 deletion affecting physical activity and ingestive behaviors.NEW & NOTEWORTHY CTRP14 is a secreted protein whose function in the peripheral tissues is largely unknown. We show that the expression of Ctrp14 in peripheral tissues is regulated by metabolic and nutritional state. We generated mice lacking CTRP14 and show that CTRP14 deficiency alters physical activity and food intake in response to fasting and refeeding. Our data has provided new and valuable information on the physiological function of CTRP14.
