简要总结
This is a single-center, single-arm study, aiming at enrolling 25 healthy adult participants to evaluate chronic effects of oil. Specifically, we aim to assess the impact on gut microbiome after a one-month intervention with oil.

入选标准
- •Males or females aged 18 to 60 years, inclusive, at enrollment.
- •BMI of ≥18.5 but \<30 kg/m
- •Healthy, as determined based on self-reported medical history.
- •No planned change in diet or medical interventions during the study.
- •Willing to collect fecal samples and retrieve sampling capsules from feces.
- •Able to understand and to sign a written informed consent prior to study enrollment.
- •Willing and able to comply with the requirements for participation in this study.
排除标准
- •Prior or suspected gastrointestinal disease (as reported by the participant) which, in the investigator/study doctor's opinion, would lead to fistula formation, intestinal stricturing, or obstruction leading to a risk of capsule non-excretion (i.e. achalasia, active ulcer disease, eosinophilic esophagitis, Crohn's disease, ulcerates colitis, celiac disease, irritable bowel syndrome, stenosis of the GI tract).
- •Any prior gastrointestinal surgery (as reported by the participant) which, in the investigator/study doctor's opinion, would lead to intestinal stricturing or obstruction leading to a risk of capsule non-excretion (i.e. previous esophageal, gastric, small intestinal, or colonic surgery). Note: appendectomy, cholecystectomy, hysterectomy, oophorectomy, hemorrhoid surgery more than 3 months prior to enrollment are acceptable.
- •History of chronic diarrhea (defined as Bristol stool scale 5 to 7; or persistent or recurrent loose or watery stools lasting for more than 4 weeks), as reported by the participant.
- •History of chronic constipation (defined as having less than 3 bowel movements per week) in the past month, as reported by the participant.
- •Any history of obstructive symptoms in the previous 3 months prior to enrollment, as reported by the participant.
- •Diagnosis of any organic motility disorder, including gastroparesis, intestinal pseudo-obstruction, systemic sclerosis, Ogilvie's syndrome, as reported by the participant.
- •Diagnosis of any malabsorption disorder (i.e. malabsorption syndrome, lactose malabsorption), as reported by the participant.
- •History of oropharyngeal dysphagia or other swallowing disorder with a risk of aspiration of the capsule, as reported by the participant.
- •Any concurrent cancer diagnosis, as reported by the participant.
- •Any cancer treatment within the past year, as reported by the participant.
