Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Not applicable. The study seeks to identify biomarkers associated with the acute and chronic consumption of cape gooseberry, and the impact of this consumption on the composition of the intestinal microbiota.

Health condition(s) code:

Healthy Volunteers

Biomarkers

Intervention(s):

Uchuva group (Experimental): Consume acutely 250 g of Cape gooseberry and during 20 days 150 /day using the scheme: Washout Period (8 days): Participants should avoid consuming Cape gooseberry, medicines of any kind, antioxidant supplements, vitamin A, β-carotene, natural products, supplements or dietary supplements or multivitamins. DAY 1 OF THE INTERVENTION (Basal): Controlled feeding designed by a nutritionist (everyone will eat the same during the day). Consume 250 ml of water sweetened with sugar (equivalent to the sugar contribution of 250 g of Cape gooseberry). Day 3 of the intervention (Acute): Controlled feeding as a day 1. They will consume 250 g of Cape gooseberry. CHRONIC INTERVENTION: Consume 150 g / day of Cape gooseberry from day 3 to 22. DAY 23 END OF THE INTERVENTION (chronic): Controlled feeding as day 1. Consume 250 ml of water sweetened with sugar (equivalent to the contribution of sugar of 250 g of Cape gooseberry).

Intervention code:

Physalis

Administration, Oral

Intervention keyword:

golden cape gooseberry

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Biomarkers of exposure to Cape gooseberry consumption in urine (Values expressed in nmol/ml determined by Liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS)). Measurement time: Day 1=Basal. 24h urine sample collected as follow: 0-6h, 6-12h and 12-24h; Day 3= Acute. 24h urine sample, after cape grossberry acute consumption, collected as follow: 0-6h, 6-12h and 12-24h; Day 23= Chronic. 24 h urine sample, after cape grossberry chronic consumption, collected as follow: 0-6h, 6-12h and 12-24h. Biomarkers of exposure to Cape gooseberry consumption will be determined in plasma (Values expressed in nmol/ml determined by Liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS)). Measurement time: Day 3= Acute. Plasma sample (10 ml of blood sample, fasting) and, 6 h after cape grossberry consumption. Day 23=Chronic. Plasma sample (10 ml of blood sample, fasting)

Key secondary outcomes:

Microbiota evaluation The abundance of OTUs (Operational Taxonomic Unites, defined at 97% similarity of DNA sequences of variable regions of the 16S rRNA gene; relative and absolute abundances will be calculated). Measurement time: Day 1= a feces sample, Day 23= a feces sample Post intervention= a feces sample, 30 days after the end of cape grossberry consumption.
