What this Trial Is About

The goal of this study is to learn if cfDNA of milk-associated intestinal bacteria (MAIB) is detectable in the bloodstream. The primary question it aims to answer is: \- Does milk consumption simultaneously increase the number of MAIB cfDNA counts in blood samples, as it does in fecal samples? Researchers will compare cfDNA counts of MAIB to those of fecal samples to assess whether the blood microbiome is a valid measure of the gut microbiome, utilizing a self-developed bioinformatics pipeline. Participants will: * Abstain from consuming any dairy products for ten days, followed by drinking milk for 7 consecutive days. * Provide blood and fecal samples before dairy abstinence, as well as at 0, 24, and 48 hours, and one week after the reintroduction of milk.
