Yes — millets have been repeatedly demonstrated to improve lipid profiles by reducing LDL (bad) cholesterol, lowering triglycerides, and increasing HDL (good) cholesterol. A 2023 review in Separations (MDPI) by Sabuz et al. confirmed millets' anti-cholesterol properties as a primary health benefit, attributing these effects to their dietary fiber, phytosterols, and bioactive polyphenols.
How millets reduce cholesterol:
Dietary fiber (sorghum, proso, barnyard): Soluble fiber binds bile acids in the gut (a process called enterohepatic cycling interruption), forcing the liver to convert more LDL cholesterol into bile — directly reducing circulating LDL levels.
Phytosterols: Structurally similar to cholesterol, plant sterols in millets competitively inhibit intestinal cholesterol absorption, reducing blood cholesterol by 5–15% in clinical studies.
Beta-glucan-like polysaccharides: Millets contain soluble polysaccharides that form viscous gels in the gut, delaying fat and cholesterol absorption.
Foxtail millet lipid profile: A clinical study found that type 2 diabetics on a foxtail millet-enriched diet had significantly lower blood cholesterol and triglyceride levels.
Pearl millet omega-3: ALA omega-3 fatty acids support triglyceride reduction and increase HDL cholesterol production in the liver.
Triglyceride reduction: Pearl millet has been specifically shown to reduce triglyceride levels — a key cardiovascular risk factor — through its high fiber content and insulin-sensitizing properties.
Practical integration: Replacing white rice or refined wheat with 2 daily servings of whole-grain millet can produce measurable LDL cholesterol reductions within 4–8 weeks of consistent consumption.
