Study Finds Dietary Fiber Inversely Associated With Depression in Pre-Menopausal Women
Dietary fiber adds bulk to your diet and makes you feel full faster, which may help control weight. It can also help digestion and help prevent constipation. A new study has found that there may be an inverse association between dietary fiber intake and depression in premenopausal women.
Participants in the study included 5,807 women who took part in the Korea National Health and Nutritional Examination Survey. The researchers used a 24-hour recall questionnaire to assess dietary fiber intake. Depression was evaluated using the Patient Health Questionnaire-9.
The researchers found that premenopausal participants with the highest dietary fiber intake had the lowest risk of having depression. They also found an inverse association between dietary fiber intake and depression in premenopausal women. No significant difference was found in postmenopausal women.
The researchers noted that this benefit may be due to gut-brain interactions. Fiber improves the richness and diversity of gut microbiota. Previous studies have suggested that changes in gut microbiota composition may affect neurotransmission.
The study was conducted by researchers from the Seoul National University College of Medicine.It was published online ahead of print on December 21, 2020 in the journal Menopause.
