Climate Friendly and Ecological Food on Microbiota

Participants in the 'Climate friendly' group will be assigned a diet generating low emissions of greenhouse gases. The target is to reduce the participants' diet-related carbon dioxide equivalents (CO2e) to 2.5 kg per person and day, which is approximately a reduction by 50% compared the average CO2e, according to a previous study on diet-related CO2e in Sweden. The participants will be instructed to reduce their consumption of beef and dairy products and increase their consumption of plant-foods i.e. fruits, vegetables, legumes and whole-grain cereals.

Participants in the 'Organic group' will be assigned an organic diet with very low, or no, content of pesticides. The participants will be instructed to replace at least 50% of their food intake with organic foods.
