About this trial
This is a clinical trial aimed to investigate if a novel phytochemical and fibre-rich snack can improve perimenopausal symptoms and well-being in perimenopausal women aged 40-55 and not on hormone replacement therapy.
Hypothesis: The investigators hypothesise that the phytochemical and fibre-rich snack will improve perimenopausal symptoms via a gut microbiota mediated mechanism.
Main research questions:
Does eating the snack every day lower menopause symptoms such as hot flushes, night sweats, mood changes, and sleep problems? Does the snack improve mood, stress, anxiety, sleep, and overall quality of life? Does the snack improve the balance of bacteria in the gut, and could this be part of how it helps symptoms?

Trial outcomes
Primary outcomes
Changes in menopause rating scale (MRS) of perimenopausal women
To assess menopause-related symptoms of perimenopausal women, using the menopause rating scale (MRS). The scale consists in 11 items ranging from 0 (none) to 4 (very severe).
Secondary outcomes
Changes in subjective (perceived) stress level of perimenopausal women
The subjective stress level of perimenopausal women are assessed using the Perceived Stress Scale (PSS) questionnaire. The scale consists in 10 items rated on a 5-point Likert scale.
Changes in affect in perimenopausal women
To assess the affect of perimenopausal women, using the Positive and Negative Affect Schedule (PANAS-SF) questionnaire, consisting of 20 items rated from 1 (very slightly or not at all) to 5 (extremely).
Changes in female sex hormone levels of perimenopausal women
To assess the female sex hormone levels of perimenopausal women, measured several esterone levels in blood samples using the randox clinical biochemistry analyser.
Changes in cognitive function of perimenopausal women
To assess cognitive function of perimenopausal womenm using Cognitive Failures questionnaire (CFQ). The questionnaire consists of 25 questions rated on a 5-point Likert scale from 0 ("Never") to 4 ("Very often").
Other outcomes
Plasma and Urinary metabolites of (poly)phenols of perimenopausal women
In total more than 160 phenolic compounds and phase 2 metabolites will be measured in plasma and urine samples by LC-MS.
