Isolated source monitoring recollection deficits indicate that abnormalities in glucose metabolism are not detrimental for global episodic memory processes. This enhances our understanding of how metabolic disorders are associated with memory impairments.

There are limited studies that describe patient meal preferences in hospital; however this data is critical to develop menus that address satisfaction and nutrition whilst balancing resources. This quality study aimed to determine preferences for meals and snacks to inform a comprehensive menu revision in a large (929 bed) tertiary public hospital. The method was based on Vivanti et al. (2008) with data collected by two final year dietetic students. The first survey comprised 72 questions, achieved a response rate of 68% (n = 192), with the second more focused at 47 questions achieving a higher response rate of 93% (n = 212). Findings showed over half the patients reporting poor or less than normal appetite, 20% describing taste issues, over a third with a LOS >7 days, a third with a MST _ 2 and less than half eating only from the general menu. Soup then toast was most frequently reported as eaten at home when unwell, and whilst most reported not missing any foods when in hospital (25%), steak was most commonly missed. Hot breakfasts were desired by the majority (63%), with over half preferring toast (even if cold). In relation to snacks, nearly half (48%) wanted something more substantial than tea/coffee/biscuits, with sandwiches (54%) and soup (33%) being suggested. Sandwiches at the evening meal were not popular (6%). Difficulties with using cutlery and meal size selection were identified as issues. Findings from this study had high utility and supported a collaborative and evidenced based approach to a successful major menu change for the hospital.

Plusieurs études ont démontré que la consommation d’un repas à indice glycémique bas (LGI) avant un exercice physique favorisait l’oxydation des lipides, diminuait les épisodes d’hypoglycémie et améliorait la performance. Par contre, d’autres recherches n’ont pas observé ces bénéfices. Le but de cette étude consiste à démontrer l’impact de l’ingestion de déjeuners avec différents indices glycémiques (IG) sur la performance en endurance de cyclistes de haut niveau. Dix cyclistes masculins ont complété trois protocoles attribués de façon aléatoire, séparés par un intervalle minimal de sept jours. Les trois protocoles consistaient en une épreuve contre la montre, soit trois heures après avoir consommé un déjeuner à indice glycémique bas ou élevé contenant 3 grammes de glucides par kg de poids corporel, soit à compléter l’exercice à jeun. Les résultats obtenus pour le temps de course montrent qu’il n’y pas de différence significative entre les protocoles. Par contre, on observe que le nombre de révolutions par minute (RPM) est significativement plus élevé avec le protocole à indice glycémique élevé (HGI) (94,3 ± 9,9 RPM) comparativement au protocole à jeun (87,7 ± 8,9 RPM) (p<0,005). Au niveau de la glycémie capillaire, on observe que durant l’exercice, au temps 30 minutes, la glycémie est significativement supérieure avec le protocole à jeun (5,47 ± 0,76 mmol/L) comparé à HGI (4,99 ± 0,91 mmol/L) (p<0,002). Notre étude n’a pas permis de confirmer que la consommation d’un repas LGI avant un exercice physique améliorait la performance physique de façon significative. Cependant, notre recherche a démontré que la diversité des protocoles utilisés pour évaluer l’impact de l’indice glycémique sur la performance physique pouvait occasionner des variations positives dans les temps de courses. Par conséquent, il s’avère nécessaire de faire d’autres recherches qui reproduisent les situations de compétition de l’athlète soit la course contre la montre.

Abnormalities in glucose tolerance such as type 2 diabetes can have demonstrable negative effects on a range of cognitive functions. However, there was no evidence that low GL breakfasts administered acutely could confer benefits for cognitive function (ClincalTrials.gov identifier, NCT01047813).

In vitro, the addition of lipids to a carbohydrate food has been found to increase the digestibility of starch. In contrast, in vivo studies have shown that the addition of fat to a food can reduce the glycaemic response (GR). The aim of this study was to assess if delayed gastric emptying (GE) causes reduced GR with the addition of lipids to a carbohydrate food and if a relationship between GR and in vitro digestion of starch exists for high fat foods. Ten healthy volunteers were tested on five occasions after consuming pancakes containing 50 g of available carbohydrate and 202 kcal of sunflower oil, olive oil, butter, medium chain triglyceride (MCT) oil or a control containing no oil. GR was measured using fingerpick blood samples, satiety using visual analogue scales and GE using the 13C octanoic acid breath test. There was a significant difference in GR between the different pancake breakfasts (p = 0.05). The highest GR was observed following the control pancakes and the lowest following the olive oil pancakes. There were significant differences in GE half time, lag phase and ascension time (p < 0.05) between the different pancakes with the control pancakes having the shortest GE time and the MCT pancakes the longest. There was a significant difference in satiety parameters fullness (p = 0.003) and prospective consumption (p = 0.050), with satiety being lowest following the control pancakes. There was a significant inverse correlation between the GR and all satiety parameters. A significant inverse correlation (p = 0.009) was also observed between the digestibility of starch in vitro and GR in vivo. The paper indicates that the digestibility of starch in vitro does not predict the GR for high fat containing foods
