Can LDL help with Darmgesundheit?

There is no strong evidence that LDL directly supports gut health. LDL is primarily a carrier of cholesterol and triglycerides in the bloodstream. Some mechanistic studies suggest LDL particles may interact with gut microbiota or modulate inflammation, but these findings are preliminary and mostly from animal or in vitro models. Human data linking LDL levels to gut health outcomes are lacking, and high LDL is a well-established cardiovascular risk factor. For improving gut health, evidence-based strategies include a high-fiber diet, prebiotics/probiotics, and reducing processed foods. LDL testing alone does not provide actionable information about the gut microbiome. Evidence grade: mechanistic/unclear. Caveat: Do not attempt to raise LDL for gut health; focus on proven dietary interventions.
