S1A | Menstrual cycle: LP (FCD17~27) vs. FP (FCD6~14), between- subjects | FCM | British blood sausage vs. Harbin red sausage, real Choice | Café consumers (N = 84; M age = 24.47, SD = 5.70) | Women in the LP chose novel foods more than those in the follicular phase. |
S1B | Menstrual cycle: LP (FCD17~27) vs. EFP (FCD6~8) vs. OP (FCD9~14), between-subjects | FCM | British blood sausage vs. Harbin red sausage | Sojump ( N = 244; M age = 31.81, SD = 5.40) | Women in the LP chose novel foods more and there was no significant difference between EFP and OP. |
S1C | Menstrual cycle: Mid-luteal day (23rd day) vs. ovulation day (14th day), within-subjects | FCM and BCM | Preference for biryani, clean meat burgers | Students (N = 52; M age = 21.00, SD = 1.88) | Women preferred the novel food on the mid-luteal day rather than their ovulation day. |
S2 | Estradiol, progesterone testing | Hormone detection in saliva | Three groups on food choices | Students (N = 65; M age = 21.69, SD = 2.19) | Progesterone positively predicted the preference for novel foods, while Estradiol did not significantly predict it. |
S3 | 2 (Menstrual cycle: LP (RCD2~13) vs. FP (RCD14~24)) × 2 (Food type: novel food vs. familiar food), between-subjects | BCM | Clean meat burger/Classic beef burger Preferences | Students (N = 112; M age = 21.41, SD = 1.50) | For familiar foods, the preference effect of the menstrual cycle disappeared. |
S4 | LP (FCD16~27) vs. FP (FCD5~15), between-subjects | FCM | Clean meat burger vs. Classic beef burger | Credamo (N = 109; M age = 28.93, SD = 5.88) | The mediating effect of perceived shortage of food was significant. |
S5 | 2 (Menstrual cycle: LP (RCD2~13) vs. FP (RCD14~24)) × 2 (Shortage of food: shortage vs. control), between-subjects | BCM | Clean meat burger vs. Classic beef burger | Credamo (N = 173; M age = 30.21, SD = 5.93) | For controls, novel foods were preferred during the LP; for women who activated the food shortage, the menstrual cycle difference in novel food preference disappeared. |
S6 | 2 (Menstrual cycle: LP (FCD17~27) vs. FP (FCD6~14)) ×Continuous (food neophobia), between-subjects | FCM | Intention to taste sea worm jelly, oyster omelette and Shacha noodles | Tourists (N = 96; M age = 33.21, SD = 6.95) | For women with low food neophobia, they preferred novel foods during the LP (vs. FP); for women with high food neophobia, there was no significant menstrual cycle differences in novel food preferences. |
S7 | 2 (Menstrual cycle: LP (RCD2~13) vs. FP (RCD14~24)) × 2 (Food risk: salient vs. control), between-subjects | BCM | Preferences for Vietnamese insect food | Sojump (N = 268; M age = 29.61, SD = 5.26) | For the control group, they had a higher preference for novel foods during the LP; for the salient food risk group, they had a lower preference for novel foods during the LP than during the FP. |
