Editorial Special Issue: 2022 consortium for trans-pyrenean investigations on obesity and diabetes.

This Special Issue of the Journal of Physiology and Biochemistry contains 7 contributions that have been elaborated in the context of the mini-network "Consortium of Trans-Pyrenean Investigations on Obesity and Diabetes" (CTPIOD), which is on its 19th year of existence. This scientific community, mostly involving research groups from France and Spain, but also open to participants coming from other countries, is focused on investigating the molecular and physiological mechanisms implicated in the development of obesity, diabetes, non-alcoholic fatty liver disease, and other noncommunicable diseases, as well as new preventive and therapeutic strategies. This special issue covers novel nutritional, molecular, and physiological aspects related to these metabolic diseases. Some of these papers emerge from the lectures of the 19th Conference on Trans-Pyrenean Investigations in Obesity and Diabetes, organized by the University of Zaragoza and celebrated in the town of Jaca (Spain) on 17-18th October 2022, and have been prepared in collaboration between different groups of the network. Many lectures were focused on the preventive role of specific fatty acids, dietary phenolic compounds and other phytochemicals against metabolic disorders. Consequently, we encouraged submission of original research in this field for this special issue.
