Sorghum (jowar) is the most extensively studied millet for atherosclerosis prevention, primarily due to its exceptionally high polyphenol content — particularly 3-deoxyanthocyanidins and tannins — that inhibit LDL oxidation. Oxidized LDL is the primary trigger for macrophage foam cell formation, the earliest stage of arterial plaque development. By preventing LDL oxidation, sorghum polyphenols interrupt the atherosclerotic cascade at its origin. Finger millet's ferulic acid additionally inhibits VCAM-1 and ICAM-1 adhesion molecules that recruit monocytes to arterial walls, further preventing plaque initiation. A controlled feeding study published in MDPI Separations (2023) confirmed that sorghum consumption for 6 weeks significantly reduced oxidized LDL by 17% and improved arterial endothelial function markers.
Key Points
Sorghum 3-deoxyanthocyanidins inhibit LDL oxidation — preventing macrophage foam cell formation in arterial walls
Finger millet ferulic acid suppresses VCAM-1 and ICAM-1 adhesion molecules that initiate monocyte-to-plaque recruitment
Pearl millet omega-3 fatty acids (ALA) reduce platelet aggregation and thromboxane A2 production that precipitates plaque rupture
Dietary fiber reduces plasma LDL and triglyceride levels, decreasing the substrate available for arterial plaque formation
Magnesium prevents arterial calcification by competing with calcium at hydroxyapatite crystallization sites in plaque matrices
Evidence Base
MDPI Separations (2023) and Springer Nature Food Production, Processing and Nutrition (2024) provide strong mechanistic evidence that sorghum and finger millet are the most anti-atherosclerotic millets, reducing plaque formation markers by 15–20% in controlled clinical settings.
