Project partners at the University of Helsinki have recently published a new paper entitled “Replacing Animal-Based Proteins with Plant-Based Proteins Changes the Composition of a Whole Nordic Diet – A Randomised Clinical Trial in Healthy Finnish Adults”.
This paper gives the results from an investigation on the effects of partial replacement of dietary animal proteins with plant-based ones on intake of energy-yielding nutrients, fibre, and plasma liloproteins. The randomised clinical intervention was conducted over 12-weeks comprised of 107 women and 29 men, between the ages of 20 – 69 years in three diet groups with different dietary protein compositions (“ANIMAL”: Animal 70% / plant 30%; “50/50”: Animal 50% / plant 50%; “PLANT”: Animal 30%/ plant 70%; All: Protein intake: 15 E%). This intervention study aimed to understand the effects of replacing animal proteins with plant-based proteins on gut health and biomarkers for type 2 diabetes and colorectal cancer.
The paper is of particular interest to the SIMBA project because research as part of the project (led by the University of Helsinki) builds upon this study, using the same samples, to determine and model the composition and activity of human gut microbiota that associates with markers of gut and metabolic health by utilising samples and data from the study presented in this paper. This work contributes to an overall objective of the project to address how sustainable food affects and shapes the human gut microbiota, thereby improving intestinal and systemic health.
