Significant β’s are shown in boldface type (p < 0.05). Participants following a vegan diet: F change (6,40) = 3.818, p = 0.004; participants following a vegetarian diet: F change (6,93) = 3.657, p = 0.003; participants following an omnivorous diet: F change (6,100) = 9.519, p = 0.000. ΔR²: the change in R².
