Second Ysonut Symposium on Medical Nutrition, held on Saturday April 9 in Barcelona, attended by over 200 doctors and health professionals

This meeting with leading-edge research aimed to expose the latest developments in nutrition, chronobiology, micro-nutrition and neuro-nutrition.

The first of the six speakers was Doctor Jean-Yves LeGoff from St. Brieuc (France), who stressed the importance of protein diets for the management of glucose metabolism and diabetes. The presentation was illustrated with clinical cases of great interest that collected positive changes over more than ten years.

Professor Alfredo Martinez, from the University of Navarra (Spain), specialist in Nutrition and Food Sciences, presented the latest validated data on the importance in low calorie diets for nutritional treatment of obesity. Thanks to an increased protein intake and the consumption of low glycaemic index foods, these diets produce effects with a wide range of benefits on health. This has been confirmed by the large DIOGENES European study, which Professor Martinez has co-promoted, recently published in several international journals.

Professor Daniel Rigaud, Head of the Endocrinology wing at the Dijon University Hospital Centre (France) and researcher at the French National Centre for Scientific Research (CNRS), presented a comparative clinical study demonstrating that supplementation with precursors of the neurotransmitters responsible for mood and satiety optimises the effectiveness of classical protein diet. The importance of the results obtained on weight reduction with the supplemented products increases proportionally with being overweight. These dopamine and serotonin precursors provide a better quality of life.

Professor Carmen BARRIGA from the University of Extremadura (Spain), Neuro-Immune Physiology and Chrononutrition Researcher, presented the latest developments of her nutritional chronobiology work and, in particular, on how to improve the nutrition of infants by supplementation with neuromediator precursors. Other clinical studies conducted on adults have shown clearly that tryptophan supplementation increases rates of serotonin and melatonin, which leads to improved sleep and enhances the body’s antioxidant capacity.

Professor Olivier COUDRON from the University of Burgundy (France), recalled the various biological rhythms of the brain, rhythms governed by the synthesis of neurotransmitters, especially catecholamines and indolamines. It is in the treatment of stress and anxiety where research on these neurotransmitters is more active, allowing for example to better understand the different stages of their synthesis and gaps that may even lead to “burn out”. Certain new biological tests can help to treat each patient based on their state of deprivation in neurotransmitters.

The last presentation, by Professor Ascension MARCOS (Spain), President of the European Congress on Nutrition and representative of the Spanish Food Safety Agency for the European Council, addressed obesity, inflammation and the intestinal ecosystem. He stressed the importance of the relationship between intestinal microbiota and the immune system, as well as the implications of this microbiota in disorders such as obesity, inflammatory diseases and resistance to insulin. The use of specific probiotics offers new ways of preventing these disorders.
