Phase 1 dietary intervention
Dietary intake during the intervention period is displayed in In OMNI1, of the 131 ± 20-g protein consumed per day, 89 ± 14-g was provided by animal-derived sources and 42 ± 8-g from non-animal sources, corresponding to 68 ± 2% and 32 ± 2% from animal and non–animal-derived sources, respectively. Meat products provided 40 ± 1-g and dairy products (including the milk protein supplement) provided 49 ± 13-g protein per day, corresponding to 32 ± 5% and 37 ± 5% of total protein, respectively. The milk protein supplement alone provided 31 ± 0-g protein per day (24 ± 4% of total protein). In VEG1, of the 127 ± 16-g protein consumed per day, 68 ± 7-g protein was derived from mycoprotein (28 ± 7-g mycoprotein-containing products, and 40 ± 3-g from supplementary isolated mycoprotein) corresponding to 54 ± 4% total protein intake. Remaining protein was provided by wheat and potato protein also contained in mycoprotein containing vegan products (17 ± 4-g protein per day, and 20 ± 2% of total protein), and from the protein present in the other elements of the diet. Overall, mycoprotein-containing products provided 46 ± 11-g daily protein and accounted for 36 ± 5% total daily protein intake.
