Adherence to a Mediterranean diet is associated with lower incidence of frailty: A longitudinal cohort study
2018
Background & aims There is a paucity of data investigating the relationship between the Mediterranean diet and frailty, with no data among North American people. We aimed to investigate if adherence to a Mediterranean diet is associated with a lower incidence of frailty in a large cohort of North American people. Methods This study included subjects at higher risk or having knee osteoarthritis. Adherence to the Mediterranean diet was evaluated using a validated Mediterranean diet score (aMED) as proposed by Panagiotakos and classified into five categories. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of ≥2 out of: (i) weight loss ≥5% between b…
Hypothalamic eIF2 alpha signaling regulates food intake
2014
International audience; The reversible phosphorylation of the a subunit of eukaryotic initiation factor 2 (eIF2 alpha) is a highly conserved signal implicated in the cellular adaptation to numerous stresses such as the one caused by amino acid limitation. In response to dietary amino acid deficiency, the brain-specific activation of the eIF2 alpha kinase GCN2 leads to food intake inhibition. We report here that GCN2 is rapidly activated in the mediobasal hypothalamus (MBH) after consumption of a leucine-deficient diet. Furthermore, knockdown of GCN2 in this particular area shows that MBH GCN2 activity controls the onset of the aversive response. Importantly, pharmacological experiments demo…
The Effects of Intensive Weight Reduction on Body Composition and Serum Hormones in Female Fitness Competitors.
2017
Worries about the potential negative consequences of popular fat loss regimens for aesthetic purposes in normal weight females have been surfacing in the media. However, longitudinal studies investigating these kinds of diets are lacking. The purpose of the present study was to investigate the effects of a 4-month fat-loss diet in normal weight females competing in fitness-sport. In total 50 participants finished the study with 27 females (27.2 +/- 4.1 years) dieting for a competition and 23 (27.7 +/- 3.7 years) acting as weight-stable controls. The energy deficit of the diet group was achieved by reducing carbohydrate intake and increasing aerobic exercise while maintaining a high level of…
Improving food offer in order to prevent and tackle undernutrition
2021
When a person shows a decline in appetite or loses weight, is essential to adapt his/her diet in order to fulfil the nutritionc needs and prevent undernutrition. Three axes must but considered and combined: enriching diet (increasing the content of essential nutrients in a meal without increasing! the volume to be ingested); adapting food texture to orc capacities (chewing, salivation, swallowing); optimizing food sensory characteristics by taking into account food habit and food preferences.
