Nutrition Winter School is a scientific seminar that revolves around various topics related to nutrition and the gut. Ever since we organised this event for the first time in 2009, the purpose of the seminar has been to gather early-career scientists and top researchers from various backgrounds and enjoy scientific lectures and fruitful discussions under the magical atmosphere of the Finnish Lapland. The 6th Nutrition Winter School will take place in January 2020 at Levi, the biggest ski resort in Finland, and this time, the theme of seminar is Diet & Microbes: Gut health for the brain and body. Come join us for a week full of science and snow!
