简要总结
The purpose of this clinical trial was to evaluate the effects Lactococcus cremoris spp. im-mobilized on oat flakes on human microbiome and blood and urine biomarkers of associated with human health.
详细描述
All eligible and consenting individuals were assigned a unique code for identification purposes. They were then randomly assigned to either the probiotic or placebo group. The probiotic group received oat flakes containing immobilized Lactococcus cremoris, while the placebo group received oat flakes indistinguishable in color, smell, and taste from the flakes with immobilized probiotics.Participants received written instructions on storing the product, which required refrigeration. They were instructed to consume 5 g of oats daily with a meal, ensuring the meal's temperature remained below 35 °C and was non-acidic (e.g., with yogurt). Biological samples were collected at three time points; before intervention, at 6th and 12th week.
