The idea of “opening arteries” is common in everyday language, but medically, narrowing from plaque is not something a single food or drink can instantly reverse. The most effective strategy is to slow progression and reduce risk drivers while using evidence-based medical therapy when needed. Nutritionally, a Mediterranean-style pattern, higher fiber intake, and cutting trans fats and ultra-processed foods can improve LDL levels and inflammatory load. Regular exercise supports vascular function and helps stabilize blood pressure. Quitting smoking is one of the most powerful interventions available. If cholesterol or hypertension is elevated, clinician-guided medication (such as statins or antihypertensives) is often the strongest real-world tool for protecting arteries. If symptoms suggest significant narrowing, imaging and cardiology evaluation are required. The safest outcome comes from a scientific plan, not quick claims.
