- FODMAPs, inflammatory bowel disease and gut microbiota: Updated overview on the current evidencePublication . Simões, Catarina D.; Maganinho, Marta; Sousa, Ana S.Based on the fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) hypothesis, the low-FODMAP diet has been suggested as a potential therapeutic approach for infammatory bowel disease (IBD) with promising results on disease management. However, this diet implies a specifc broad food restriction, which potentially increases the risk of nutritional defciencies and may aggravate gut microbiota dysbiosis of IBD patients. The aim of the present study is to review the efect of individual FODMAPs on the human gut microbiota. In addition, this narrative review provides an updated overview of the use of the low-FODMAP diet in IBD, namely the implementation, advantages, limitations, and the impact on the gut microbiota

- Nutrition up 65 educational strategies: health professionals qualification coursePublication . Sousa, Ana S.; Guerra, Rita. S; Álvares, Luísa; Valdiviesso, Rui; Padrão, Patrícia; Borges, Nuno; Santos, Alejandro; Afonso, Cláudia; Martins, Cátia; Ferro, Graça; Moreira, Pedro; Amaral, Teresa F.INTRODUCTION: Nutrition knowledge among health professionals has a major impact on older adults’ healthcare. However, there is a lack of specialized education offer in this area. Within the Nutrition UP 65 Project, a health professional’s qualification nutrition course was created and implemented from April 2015 to April 2017. We aim to describe this process here. METHODOLOGY: At Faculdade de Ciências da Nutrição e Alimentação da Universidade do Porto, a course of twenty-seven hours was created by six professors. The course comprises eight hours of direct contact and nineteen hours of individual study and was accredited by the University of Porto and credited with one European Credit Transfer System (ECTS). Educational materials and presentations for each session were produced including posters and flyers. A final test was developed to evaluate attendee’s knowledge. Approximately 10% of national health units were identified, randomly selected in each country regional area (NUTS II – “Nomenclatura Comum das Unidades Territoriais para Fins Estatísticos”) and invited to participate. RESULTS: Thirty-five course editions were carried out by twenty-three Porto University accredited instructors for 784 professionals from 241 different health units. Concerning the knowledge evaluation, a 99% approval rate was achieved and the average mark score was of 16.8 out of 20. Course satisfaction survey revealed that 45.7% of the participants classified the course as “good” and 41.1% as “very good”. CONCLUSIONS: The overall balance of this branch of the Nutrition UP 65 project is very positive. The results on health professional’s adherence demonstrate that the interest in this area of nutrition care is high and that this nutrition course is a good opportunity to expand access to specialized education. This highlights the need for further initiatives promoting educational sessions targeting nutrition topics. These course sessions must be acknowledged as a starting point to a new approach in older adult’s nutrition knowledge in Portugal.
- The Effect of β-Hydroxy-β-Methylbutyrate on Muscle Strength and Functional Outcomes in Older AdultsPublication . Mendes, Joana; Guerra, Rita S.; Sousa, Ana S.Nutritional intervention is increasingly being recognized as playing an important role in functional status. The supplementation with β‑hydroxy-β-methylbutyrate (HMB), which is a metabolite of an essential amino acid, may be an effective nutritional intervention to improve muscle strength and functionality in older adults. The aim of this narrative review was to present an updated overview of the effects of HMB supplementation in older adults, specifically on muscle strength and functional outcomes. A PubMed database search was performed and only randomized controlled trial studies were included. More than half of the 14 analyzed studies reported that HMB supplementation improved muscle strength and other functional outcomes. HMB supplementation has demonstrated some promising effects on muscle strength and functional outcomes in older adults with different conditions of health and physical activity.
