- W4296142904 abstract "Golden berry (Physalis peruviana) is a tropical fruit rich in antioxidants that has been proposed to be able to control the lipid profile in hypercholesterolemic patients. Dyslipidemia is an independent risk factor for cardiometabolic diseases. The gut microbiota is strongly associated with cardiometabolic risk and is involved in redox balance, intestinal permeability, and inflammation. However, the impacts of golden berry on some of these factors, including the human gut microbiota, have never been tested, and there are no tools for compliance monitoring or dietary intake assessment regarding nutritional interventions with this fruit. In the pre-post quasi-experimental nutritional intervention presented here, 18 adult men (27-49 years old) consumed golden berries (Dorada variety) for three weeks. We evaluated putative biomarkers of exposure through an untargeted metabolomics approach (liquid chromatography-mass spectrometry LC-MS), quantified the biomarkers of oxidative stress, gut permeability, and inflammation in plasma, and assessed the effects of fruit intake on the gut microbiota through 16S rRNA gene sequencing of feces (Illumina MiSeq V2). First, syringic acid and kaempferol were identified as putative biomarkers of golden berry consumption. Intervention with this fruit promoted physiological changes in the participants after three weeks, reducing the level of the oxidative stress marker 8-isoprostane (-148 pg/ml; 36.1 %; p = 0.057) and slightly altering gut permeability by increasing the plasma levels of LBP (2.91 µg/ml; 54.6 %; p = 0.0005) and I-FABP (0.15, 14.7 %, p = 0.04) without inducing significant inflammation; i.e., the levels of IL-1β, TNF-α and IL-8 changed by 0.7 (2.0 %), -4.0 (-9.6 %) and -0.4 (-1.8 %) pg/ml, respectively. Notably, the consumption of golden berries did not affect the gut microbiota of the individuals consistently but instead shifted it in a personalized manner. The compositions of the gut microbiota of a given individual at the end of intervention and one month after the end of intervention were statistically more similar to their own baseline than to a corresponding sample from a different individual. This intervention identified putative biomarkers of golden berry intake along with potential benefits of its consumption relevant to cardiometabolic disease risk reduction. Golden berries are likely to positively modulate redox balance, although this effect must be proven in a future controlled clinical trial." @default.
