A study on the role of eggs in sleep wins the IEH 2025 Research Award

The IEH (Instituto de Estudios del Huevo) has awarded its annual research prize to Marta Garaulet, professor of physiology and nutrition, researcher and entrepreneur, for her project “The egg as a sleep modulator: Evidence from chrononutrition and circadian rhythms“.

The award ceremony was held on Wednesday, 8 October 2025, at the Círculo de Bellas Artes in Madrid, coinciding with World Egg Day, and aims to support young researchers and teams working across the many fields related to eggs.



The prize, endowed with €12,000, will contribute to the continuation of this research, as it has been doing since 1997 (see the full list of all prizes awarded at the foot of this article). The team led by Dr Garaulet at the University of Murcia, dedicated to Chrononutrition, aims to determine whether a food as complete as the egg can help us sleep better thanks to its natural tryptophan and melatonin content, especially when consumed at the right time of day.

For the professor of physiology and nutrition, “In Spain it has traditionally been common to include eggs at dinner — in the form of Spanish or French omelette, fried eggs or soft-boiled eggs — and we want to determine whether this habit, as well as being healthy, can promote sleep, both in terms of duration and quality. This award recognises the importance of investigating the relationship between diet and sleep from the perspective of circadian rhythms, and drives us to continue generating solid scientific evidence. We are grateful to the Instituto de Estudios del Huevo for its support of projects that integrate nutrition and health, and for its commitment to innovative research.”

In addition, cardiologist and science communicator Aurelio Rojas was awarded the Gold Prize.


The egg in the digital age: INPROVO and the Instituto de Estudios del Huevo debunk myths about this food


As part of the World Egg Day 2025 celebrations, the Instituto de Estudios del Huevo (IEH), jointly with the Organización Interprofesional del Huevo y sus Productos (INPROVO), at the same event held on 8 October 2025 at the Círculo de Bellas Artes in Madrid, organised a Round Table focused on debunking myths about this food in the digital age. The ceremony was opened by the President of the Instituto de Estudios del Huevo, Dr Pablo Catalá.

A highlight was the presentation of a pioneering study by Mónica Díaz-Ponte, Managing Director of Digital Addiction, who presented her work on the territory of eggs in the digital age, based on the analysis of more than 134,000 Spanish digital conversations (2022–2025) revealing how the egg has become the unexpected protagonist of the digital food revolution, positioning itself simultaneously as a gourmet product, natural supplement and symbol of “real food”.

The event also included a round table with experts in nutrition and communication, and culminated with the aforementioned presentation of the 2025 Research Award to Marta Garaulet and the 2025 Gold Prize to Aurelio Rojas.

The IEH Awards: an incentive for research into eggs and their benefits

The awards of the Instituto de Estudios del Huevo (IEH) were established in 1996 and are presented annually with the aim of recognising and honouring Spanish researchers who advance knowledge and dissemination on eggs, and who promote projects related to sustainability in egg and egg product production, their composition, quality, technology, and their appropriate use and consumption. 💡
