Soy Isoflavone Extract Does Not Increase the Intoxicating Effects of Acute Alcohol Ingestion in Human Volunteers.

ABSTRACT: Soy beans contain isoflavones, including daidzein and genistein, with biological activities related to therapeutic effects in reducing osteoporosis, decreasing adverse menopausal manifestations, providing protection from cardiovascular diseases, and reducing hormone-dependent cancers and age-related cognitive-decline. Daidzein has been described as inhibiting the aldehyde-dehydrogenase-2 enzyme (ALDH2), and reducing alcohol use in clinical pilot studies. Our aim was to evaluate the possible interactions between a soy extract product and alcohol in a crossover, single blind, randomized study. Ten healthy male volunteers participated in two experimental sessions: one with a single dose of alcohol (0.5 g/kg, Vodka Absolut, Sweden), and the other with four capsules of a soy extract product (Super-Absorbable Soy Isoflavones, Life-Extension, United States) and, 2 h later, the same dose of alcohol. Results showed no differences in vital signs except a slightly higher significative reduction in diastolic blood pressure at 2, 3, 4, and 8 h after administration with alcohol alone in comparison with soy extract+alcohol. Ethanol-induced subjective and adverse effects were similar for both conditions with the exception of headache (higher at 8 h after alcohol alone). Our results demonstrate that a single dose of a soy isoflavone extract did not influence alcohol pharmacokinetics and pharmacological effects and did not induce any disulfiram-reaction symptoms. Soy extract and alcohol did not interact and can be administered safely.

Project description:Porcine reproductive and respiratory syndrome virus (PRRSV) is an economically important disease, and the ingestion of soy isoflavones (ISF) may benefit PRRSV-infected pigs due to demonstrated anti-inflammatory and antiviral properties. The objective of this study was to quantify the effects of ISF consumption on fecal microbiome characteristics at different timepoints across a disease challenge and determine whether any changes, if present, elude to potential biological mechanisms for previously observed performance benefits. In total, 96 weaned barrows were group-housed in a Biosafety Level-2 containment facility and allotted to one of three experimental treatments that were maintained throughout the study: noninfected pigs receiving an ISF-devoid control diet (NEG, n = 24) and infected pigs receiving either the control diet (POS, n = 36) or that supplemented with total ISF in excess of 1,600 mg/kg (ISF, n = 36). Following a 7-d adaptation, pigs were inoculated intranasally with either a sham-control (phosphate-buffered saline) or live PRRSV (1 × 105 median tissue culture infectious dose[TCID]50/mL, strain NADC20). Fecal samples were collected from 48 individual pigs at pre-infection (-2 d post-inoculation [DPI]), peak-infection (10 DPI), and post-infection (144 DPI) timepoints. Extracted DNA was used to quantify fecal microbiota profiles via 16S bacterial rRNA sequencing. Differences in bacterial communities among diet groups were evaluated with principal coordinate analysis and permutational multivariate analysis of variance using UniFrac distance matrices based on both unweighted and weighted UniFrac distances using QIIME 2. All other data were analyzed by one-way ANOVA performed on square root transformations using R. Across all timepoints, only a few differences were observed due to ISF alone mainly in lowly abundant genera. The most notable differences observed were decreased relative abundance of Actinobacteria at 144 DPI between noninfected and infected treatments (P < 0.05), which is consistent with various dysbioses observed in other disease models. Our findings indicate that the differences present were mainly due to PRRSV-infection alone and not strongly influenced by diet, which implies that previously observed performance benefits conferred by dietary ISF are not likely due to the changes in microbiome composition.
