Training in acquisition of texture-cued fasting-anticipatory satiety in rats using high- or low-fat dietsWhite, Jennifer. January 1998 (has links)
Anticipatory satiety is the ability to reduce meal size when the diet at that meal is consistently followed by a short time interval to the next access to food. This prediction of intake is learnt, i.e. based on the association of a food's sensory characteristics with some consequence(s) of ingesting it. / Two pilot studies were conducted using male Sprague-Dawley rats in which (1) the ability of food texture to cue fasting duration was indicated by evidence of anticipatory satiety in the low-fat powder-long/paste-short group and in the high-fat paste-long/powder-short group and (2) the pattern of anticipatory satiety was seen only in the low-fat granules-long/powder-short group. / In the main experiment (n = 9), anticipatory satiety was reached twice in the highfat powder-long/pellet-short group on days 16--23 (p ≤ 0.1) and once in the low-fat pellet-long group/powder-short on days 20--23 (p ≤ 0.1). The acquisition of texture-cued fasting-anticipatory satiety seems to depend upon high-energy density of the diet and the utilisation of textures which make it easier for the rats to eat.

Gustatory effects of dietary fatSong, Hae-Jin, Chemical Sciences & Engineering, Faculty of Engineering, UNSW January 2007 (has links)
This thesis investigates whether fats, akin to other taste stimuli, exhibit sensory properties such as mixture interactions. In order to determine gustatory, rather than tactile or olfactory effects, viscosity-controlled emulsions of deodorised oils were used as the base to which taste stimuli were incorporated and presented to a panel of trained assessors. In preliminary qualitative assessments, panellists described the 10% olive oil emulsion as saltier, stronger, fattier and having a more lingering aftertaste than the non-oil control, suggesting that oil modulates taste duration as well influencing taste intensity and/or perceived quality. Panellists were unable to rate the oil/fat taste per se with any degree of certainty hence further experiments examined the effect of oil on the perception of taste mixtures. In mixture interaction experiments, the addition of oil did not result in mixture suppression or enhancement for sweet, salty, sour or bitter while it significantly enhanced umami. To determine the locus of interaction, when MSG and oil were presented to each side of the tongue separately, the enhancement effect disappeared indicating a peripheral mechanism of interaction, similar to the attenuation of chilli burn by oil. In contrast, suprathreshold sucrose sweetness was enhanced by the contralateral presentation of oil, indicating sensory processing at a higher locus. Furthermore, the addition of oil significantly reduced bitterness in a caffeine-MSG mixture. Since earlier experiments did not indicate any interaction between oil and bitterness, the decrease in the perceived bitterness of this binary mixture is attributed to an increase in umami which is likely to have suppressed bitterness, the perceptually dominant component in this mixture. These findings suggest a gustatory role for fats in modulating the taste profile of mixtures, in particular, enhancing total taste intensity, prolonging taste duration, and enhancing umami. A taste receptor-based model of fat perception provides for an orosensory mechanism capable of signalling the arrival of the most energy-dense nutrient, essential fatty acids and fat-soluble vitamins. The chemosensory signal may also be the basis for hedonic responses with subsequent implications for intake.

The effect of alterations in diet composition upon anthropometric measures, biochemical parameters, and nutrient intakes in overweight womenCook, Darci L. January 2005 (has links)
Thirty-seven overweight/obese (BMI: 25-35 kg/m2), premenopausal women that were randomly assigned to either an ad libitum low-carbohydrate (LC) (20% CHO, 30-40% protein, 30-40% fat), or an ad libitum low-fat (LF) (55-60% CHO, 15-20% protein, 20-25% fat) diet.All subjects were given weekly menus matching their assigned macronutrient requirements to aid in meal planning and dietary compliance. Baseline and post-diet measures included height, weight, body composition (DXA), blood lipids [total cholesterol (TC), HDL, LDL, and triglycerides (TG)], and plasma insulin levels. There were no significant group differences in any of the above-listed variables prior to the study. Nineteen women completed the 6-wk study (LC=11, LF=8). Compliance to the diets was adequate as indicated by weekly 24-hr recalls and daily urinary ketone levels. Both groups lost a significant amount of weight and body flat, (P<0.05); and weight and body fat losses were not significantly different between the groups. All groups experienced similar decreases in TG, TC, LDL, HDL, and insulin levels. These results indicate a LC diet is no more effective than a LF diet in promoting favorable changes in body weight, body composition, blood lipids and insulin levels. / Department of Family and Consumer Sciences

Implementing a healthy eating strategy after heart and lung transplantation : a randomised controlled feasibility studyEntwistle, Timothy January 2017 (has links)
Background: Studies evaluating the possible health-promoting effects of sound nutrition in heart and lung transplant recipients are currently lacking. Despite advances in drug treatment and patient monitoring, lifestyle-associated complications such as obesity, diabetes and cardiovascular disease occur frequently. Following transplantation, a low-fat eating pattern is currently viewed as best standard care. However, a Mediterranean diet based on a varied range of fresh unprocessed foods and supplemented with extra virgin olive oil has demonstrated clinical benefit in various non-transplant populations. The aim of this study was to evaluate the feasibility and acceptability of a Mediterranean vs a low-fat diet intervention in heart and lung transplant recipients, and to assess clinical and biochemical outcomes. Methods: This was a randomised controlled feasibility trial to evaluate a Mediterranean diet supplemented with extra-virgin olive oil, vs a modified low-fat diet in heart and lung transplant recipients at a single centre. In total, 41 clinically stable male and female (median age 55 years) transplant recipients were randomly assigned (1:1) in two separate 12-month waves (n=24 and n=17) to one of these diet interventions. A range of validated food frequency and adherence questionnaires captured changes in participants' reported eating habits to 6 weeks post-study. Clinical and biochemical analysis was conducted at baseline, 25 and 52 weeks. Telephone and outpatient contact provided a support mechanism to reinforce dietary behavioural change. Caloric intake and physical exercise awareness were discussed, but not promoted. Results: Thirty nine participants completed the trial (95%). Adherence to both interventions improved significantly at week 25, and was maintained at 52 and 58 weeks. Compared with baseline, waist circumference decreased in both groups at week 25 (p=0.024). A decrease in blood pressure and heart rate occurred at 52 weeks in the low-fat group only. At 52 weeks, higher adherence resulted in significant improvements in fasting glucose in the Mediterranean (< 4.8%) and low-fat (< 5%) groups. This respective pattern was also observed with total cholesterol (≤ 9% and ≤ 7%), triglycerides (≤ 9% and ≤ 20%) and IGF-1 (≤ 9% and ≤ 15%). A significant decrease in the LDL/HDL ratio (≤ 12%) occurred in the Mediterranean group only. Moreover, clinically relevant lipid and glucose regulation changes were observed in each intervention. Conclusions: The implementation of a prospective 12-month Mediterranean or low-fat diet is feasible and acceptable in a heart and lung transplant outpatient setting. Both interventions were positively associated with improvements in lipid and blood glucose regulation and circulating IGF-1. As part of a multidisciplinary framework, these findings offer an additional therapeutic strategy to optimise outpatient care.
