M,F,O,L and P indicate that the superscripted phase significantly differed from the menstrual, follicular, ovulatory, luteal or premenstrual phase, respectively, in post-hoc analyses.
Variable had 3 levels (1 = less than usual, 2 = about the same as usual, 3 = more than usual) and nuts/tofu has 3 levels (0=none consumed, 1 = nuts or tofu consumed, 3 = both nuts and tofu consumed)
Variable had two levels (0=absence, 1=presence)
# of cravings and spices (range 0 to 5); Health symptoms (range 0 to 4)
with more conservative tests this effect would not reach statistical significance
