Sardines are considered beneficial for supporting poor circulation primarily due to their high content of omega-3 fatty acids, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Scientific studies have shown that omega-3 fatty acids can improve cardiovascular health by reducing triglyceride levels, lowering blood pressure, decreasing platelet aggregation, and improving endothelial function, all of which contribute to better blood flow and circulation. Regular consumption of oily fish like sardines is associated with a reduced risk of cardiovascular diseases and improved vascular function. The American Heart Association recommends eating fatty fish at least twice per week for heart and circulatory health. While there are no large-scale clinical trials specifically studying sardines for "poor circulation" as a standalone symptom, the strong evidence for omega-3s in improving vascular health supports their use for this purpose. Additionally, sardines are a source of vitamin B12, which is essential for red blood cell formation and may play a role in preventing circulatory problems such as anemia. Thus, while the evidence is not disease-specific and does not equate to a direct "cure," the scientific rationale for including sardines in the diet to support overall circulation is solidly supported by clinical and epidemiological data on omega-3 fatty acids and cardiovascular health.
