This intervention involved changes in the composition of the volunteers’ diets across both study arms. During the Meat phase, volunteers’ average daily meat consumption increased from baseline by 18 g, and red and processed meat intake by 160 g, whilst during the Mycoprotein phase, individuals did not consume any meat and increased their consumption of mycoprotein by an average 240 g per day from baseline. Mean self-reported intake of total energy, protein, fat, saturated fat and sodium were not significantly changed from baseline by either diet. The Mycoprotein phase was associated with higher self-reported fibre intake, both from baseline (+ 16.99 ± 2.79 g/day,
