Primary | Number of Participants With Treatment-emergent Adverse Events Following Each Dose of Soy | Dose safety will be investigated by compiling by treatment (e.g. 10 g dose, 20 g dose, 30 g dose) a list of adverse events such as frequency of headaches, nausea, vomiting. The study physician in consultation with the coordinator will review and determine safety | One week at each dose | |
Primary | 10 g Soy-related Gastrointestinal Symptoms | Subjects will complete a gastrointestinal symptoms questionnaire. The ratings are none, mild, moderate, and severe. | One week | |
Primary | 20 g Soy-related Gastrointestinal Symptoms | Subjects will complete a gastrointestinal symptoms questionnaire. The ratings are none, mild, moderate, and severe. | One week | |
Primary | 30 g Soy-related Gastrointestinal Symptoms | Subjects will complete a gastrointestinal symptoms questionnaire. The ratings are none, mild, moderate, and severe. | One week | |
Primary | 10 g Soy-related Stool Frequency | Subjects will complete the stool frequency questionnaire. Stool frequency will be rated from 0 to more than 9 over three consecutive days in each week | One week | |
Primary | 20 g Soy-related Stool Frequency | Subjects will complete the stool frequency questionnaire. Stool frequency will be rated from 0 to more than 9 over three consecutive days in each week | One week | |
Primary | 30 g Soy-related Stool Frequency | Subjects will complete the stool frequency questionnaire. Stool frequency will be rated from 0 to more than 9 over three consecutive days in each week | One week | |
Primary | 10 Soy-related Stool Consistency | Subjects will complete a stool consistency questionnaire. Stool consistency will be rated according to the Bristol Stool Scale where scores from three to five will be considered normal and 1, 2, 6, and 7 will be considered abnormal. | One week | |
Primary | 20 g Soy-related Stool Consistency | Subjects will complete a stool consistency questionnaire. Stool consistency will be rated according to the Bristol Stool Scale where scores from three to five will be considered normal and 1, 2, 6, and 7 will be considered abnormal. | One week | |
Primary | 30 g Soy-related Stool Consistency | Subjects will complete a stool consistency questionnaire. Stool consistency will be rated according to the Bristol Stool Scale where scores from three to five will be considered normal and 1, 2, 6, and 7 will be considered abnormal. | One week | |
Secondary | 10 g Soy Intake Effect on Fecal Short Chain Fatty Acids | Measurement of fecal short chain fatty acids in response to intake of soy | One week | |
Secondary | 20 g Soy Intake Effect on Fecal Short Chain Fatty Acids | Measurement of fecal short chain fatty acids in response to intake of soy | One week | |
Secondary | 30 g Soy Intake Effect on Fecal Short Chain Fatty Acids | Measurement of fecal short chain fatty acids in response to intake of soy | One week |
