Dietary fiber, particularly soluble fiber, is scientifically validated to support cardiovascular health. Numerous epidemiological and clinical studies have demonstrated that increased intake of fiber is associated with reduced risk of cardiovascular disease (CVD). Mechanistically, soluble fiber (such as that found in oats, barley, legumes, and some fruits) can lower serum total and LDL cholesterol by binding bile acids in the gut and promoting their excretion, which reduces circulating cholesterol levels. Additionally, fiber intake is linked to improved glycemic control and reduced blood pressure, both of which are important risk factors for cardiovascular disease. Large cohort studies, such as the Nurses’ Health Study and the Health Professionals Follow-Up Study, have consistently shown that higher fiber consumption correlates with lower rates of coronary heart disease and stroke. Meta-analyses of randomized controlled trials have confirmed that dietary fiber supplementation can produce modest but significant reductions in LDL cholesterol. Due to this robust body of evidence, major health organizations, including the American Heart Association, recommend increased dietary fiber intake as part of a heart-healthy diet. However, while the evidence is strong, it is strongest for fiber from foods rather than supplements, and the effect size, while meaningful, is moderate. Thus, fiber's use in supporting cardiovascular health is well justified by scientific evidence.
