Optimum nutrition plays a major role in the achievement and maintenance of good health. The Nutrition Society of the UK and Ireland and the Sabri �lker Foundation, a charity based in T�rkiye and focused on improving public health, combined forces to highlight this important subject. A hybrid conference was held in Istanbul, with over 4000 delegates from sixty-two countries joining the proceedings live online in addition to those attending in person. The primary purpose was to inspire healthcare professionals and nutrition policy makers to better consider the role of nutrition in their interactions with patients and the public at large to reduce the prevalence of non-communicable diseases such as obesity and type 2 diabetes. The event provided an opportunity to share and learn from different approaches in the UK, T�rkiye and Finland, highlighting initiatives to strengthen research in the nutritional sciences and translation of that research into nutrition policy. The presenters provided evidence of the links between nutrition and disease risk and emphasised the importance of minimising risk and implementing early treatment of diet-related disease. Suggestions were made including improving health literacy and strengthening policies to improve the quality of food production and dietary behaviour. A multidisciplinary approach is needed whereby Governments, the food industry, non-governmental groups and consumer groups collaborate to develop evidence-based recommendations and appropriate joined-up policies that do not widen inequalities. This summary of the proceedings will serve as a gateway for those seeking to access additional information on nutrition and health across the globe.
