What is the ketogenic diet and is it worth following it? We were looking for an answer to this question during the first educational meeting carried out as part of the ERA Chairs WELCOME2 project. Scientists from our Institute invited to a joint discussion representatives of the academic community, education, local politics, innovation, health care, as well as private individuals interested in the ketogenic diet in the context of health benefits.
Dr. Natalia Drabińska from the Department of Food Chemistry and Biodynamics of the IRZiBŻ PAS explained all the key aspects of this currently very popular diet and presented the NCN project she runs: „KETO-MINOX: The impact of an isocaloric, reducing ketogenic diet on metabolism, inflammation, selected nutritional parameters and stress of overweight and obese women.

The meeting ended with a discussion panel, during which the participants of the meeting could share their questions and doubts. The experts were joined by dr hab. n. med. Elżbieta Jarocka-Cyrta, prof. UWM.
Building a network of contacts, developing leadership competences, planning and managing change, self-awareness and agency – these are just some of the topics raised by the participants of the EIT Food #WELead Polska workshop.
„We invited over 30 talented, creative and active women from our region to the #WELeadFood workshops. Women who carry out scientific research, manage their own business, create and implement regional policy, support the development of innovation, work in the education sector and non-governmental organizations or head departments in large corporations, especially in the agri-food industry. They are the leaders who manage, build R&D strategies, set goals for themselves and their teams, organize resources and take care of relations with partners”, say Iwona Kieda and Justyna Banasiak, organizers of the event from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences.
Is change a fundamental factor in achieving key leadership positions? Do contacts help break the glass ceiling? Should organizations invest in mentoring? How to run #impact #business? How to increase the participation of women in science? And finally, how to find a balance in an active professional life that will „ground” us at the moment when we need it most?
We answered these and other questions during a panel discussion with Anna Borys, Impact Director at McDonald’s Poland; Dr. Magdalena Weidner-Glunde, head of the Microbiology and Molecular Virology Laboratory at our Institute and Matilda Szyrle, CEO of Future Friendly Farm startup.
The training part of the workshop was about discovering our own resources, setting goals and planning their achievement with the trainers: Marzena Radzka-Wiśniewska and Lidia Willan.
The finale of the meeting was a networking session in the form of culinary workshops with elements of molecular gastronomy, led by scientists from our Institute, Dr. Marta Kopcewicz and Dr. Sylwia Machcińska-Zielińska.
The workshop took place on May 31 in Kuźnia Społeczna.

Tam mieli okazję przyjrzeć się roli opakowań żywności w zapewnianiu bezpieczeństwa produktów spożywczych. Uczniowie wzięli też udział w warsztatach i interaktywnej grze, dzięki którym mogli sprawdzić jak radzą sobie z prawidłową segregacją opakowań po żywności.
On November 18, you will meet our scientists at #ScienceCom, a cyclical event connecting the world of science with society, organized by the Experyment Science Center in Gdynia.
This year’s edition is devoted to the topics of sustainable development of cities and society as well as responsible consumption and production.
Researchers from our Institute, Dr. Joanna Fotschki, Dr. Marta Kopcewicz and Marzena Lenkiewicz, MSc., as part of the EIT Food InformPack project, will prepare workshops on a rational approach to purchasing, managing and disposing of food packaging. We will find out how we, consumers, can give them a second life and contribute to building a circular economy.
Thanks to EIT Food #InformPack, you tested your strength in the proper segregation of food packaging materials, deciphered the symbols placed by producers on packaging, and also learned about the original methods of waste processing.
In the EIT Food #FoodScienceClass zone, you moved to a science class where you detected the presence of starch in food, created molecular pearls and learned how to properly store food products.
Thanks to EIT Food #FarmingSimulator, you played the role of a modern farmer who uses technologies to run the farm in the most sustainable way possible, and by taking part in the quiz you learned the secrets of precision farming.
On August 13 and 14, you will meet our scientists in the education zone at the Olsztyn Green Festival 2022. Workshops, shows, quizzes, competitions and interesting conversations with experts dealing with the issue of food safety and healthy eating are waiting for you.
As part of the EIT Food #InformPack project, you will be able to take part in workshops and an interactive game that will help you check how you deal with the proper segregation of food packaging. You will decipher the symbols placed by producers on packaging, look at creative methods of waste processing and design your own shopping bags. You will be able to share with us your opinion on the ways in which you would like to receive information on a rational approach to purchasing, management and disposal of food packaging. Your opinion is very important, because it will help scientists and food producers to develop „tailor-made” educational campaigns supporting the development of pro-ecological awareness.
The EITFood #FoodScienceClass zone also includes activities developed with scientists that will be of interest to all consumers attending the festival. First, we will play with some chemistry. We will learn what starch is and examine its presence in food products, as well as make molecular pearls ourselves. Next, we will take a closer look at nutrition and food, and learn how to properly store food products in the refrigerator – so that they are safe and useful for consumption as long as possible. We have prepared attractive gifts for engagement in our shows and experiments. The #FoodScienceClass project aims to interest the youngest in a scientific career, to show them that food research can be an interesting, developing and satisfying career path. It is also an excellent platform for sharing the knowledge gained from the project on sustainable consumer practices with family and peers.
The EITFood #Farming Simulator project has prepared a lot of festival attractions for you, including the opportunity to play the role of a farmer and try your hands at precision farming, a chance to win gifts in a competition on sustainable food production methods, and take a commemorative photo in… a tractor. The main attraction of this zone will be Farming Simulator – a simulation game created by the Swiss company Giants Software. It is one of the most advanced and popular simulators in the world that allows players to learn all the secrets of farming, including precision farming. „Precision Farming”, a free add-on to the Farming Simulator game, popularizes precision farming solutions that enable farming based on the collection and processing of various data, obtained, among others, from thanks to satellite technology.

Vitamin d and its importance in our diet
We taught our youngest attendees about the impact of food on gene expression and explained that genetic differences play a role in how we respond to food. We also prepared our participants for the coming months by showing them how different barriers, such as clothing or UV filter creams, affect vitamin D synthesis during sun exposure. The Science Picnic was commended by the European Commission in 2005 as one of 10 model European projects in the “Science and Society” field.
The liver is an organ highly vulnerable to the effects of a high-fat diet. Research by scientists at the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn has shown that the best way to improve its functioning is to switch to an easy-to-digest diet together with chromium supplementation.
– All of us who eat very unhealthily will sooner or later suffer the negative consequences of our irresponsible eating behaviour, for example in the form of liver problems. The best way to improve your health is to change to a low-fat diet. In combination with new eating habits, the therapy should be supplemented with chromium supplementation, which, among other things, helps reduce fat and inflammation of the liver, emphasises Professor Jerzy Juśkiewicz from the Department of Biological Functions of Food at our Institute.
Chromium (trivalent) is a key micronutrient associated with carbohydrate, protein and fat metabolism in humans and animals. Because of its ability to regulate carbohydrate and lipid metabolism and reduce body weight, this dietary micronutrient is a popular booster for diabetes therapy and an ingredient in supplements used for weight loss. – This is a well-known relationship, but there are still disputes among scientists about the effectiveness of therapy with such supplementation alone. Indeed, some scientific studies have indicated that chromium should be treated with caution as an anti-obesity supplement, as some experiments have reported a deterioration in the functioning of some internal organs,’ points out Professor Jerzy Juśkiewicz.
Currently, the most popular form of chromium used in dietary supplements is organic chromium picolinate (Cr-Pic). Its intake can help, among other things, to reduce body weight without loss of muscle mass. – However, due to the relatively low bioavailability (i.e. absorption from the gastrointestinal tract) of Cr-Pic, the search is on for other forms of chromium that will be better utilised in the body. For these reasons, scientists have become interested in chromium complexes with amino acids and the inorganic form of chromium in the form of nanoparticles; the possibility of their application in humans, however, still requires in-depth research, which is currently being conducted on animal models, explains the researcher.
Over the past few years, Prof. Juśkiewicz’s team, together with scientists from the University of Life Sciences in Lublin (Prof. Katarzyna Ognik’s team), have been researching the biological activity of various nanoparticles that enter the digestive tract with the diet. Their most recent research project, funded by the National Science Centre, focused on chromium.
– We wanted to test whether the negative effects associated with long-term consumption of a high-fat diet, observed at the intestinal, vascular and hepatic levels, could be sequentially alleviated by dietary supplementation with different forms of chromium and/or a change in eating habits by switching to a 'normal’ – low-fat diet, says the researcher.
An excerpt from the results of the study, which was published in the International Journal of Molecular Sciences, focuses on liver function.
– The liver is the organ most exposed to the effects of eating a 'fatty’ diet and the presence of new dietary elements, namely chromium nanoparticles. Studies have clearly shown that the liver of rats fed a high-fat diet for long periods of time is simply unhealthy – fatty, 'stressed’ by free radicals and in a permanent state of inflammation. We have shown that abandoning a fatty diet in favour of a lower fat, higher fibre diet is the best solution to improve liver function. Our findings were supported by a range of assayed parameters, biochemical and molecular. Interestingly, the addition of chromium supported the therapy of changing to a 'healthier’ diet, and the chromium nanoparticles themselves were more 'helpful’ than chromium in picolinate form, says the researcher.
In the next stages of the project, the researchers will, among other things, focus on in-depth studies of chromium nanoparticles in other organs, in the context of their safety for future human consumption.
The research project entitled „Alleviation of adverse effects associated with high-fat diet through dietary patterns changes and/or supplementation of various forms of chromium” (2020/39/B/NZ9/00674) is funded by the National Science Centre (NCN). It is conducted by the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn in collaboration with the University of Life Sciences in Lublin.
