Millets exhibit a broad spectrum of disease-preventive properties due to their rich content of bioactive compounds, dietary fiber, and essential micronutrients. A 2023 review in Discover Food (Springer Nature) emphasized that millets are 'climate-smart, nutrient-dense grains that can play a pivotal role in tackling chronic diseases worldwide.' Their nutraceutical properties address multiple disease pathways simultaneously.
Disease-preventive roles of millets by category:
Cardiovascular disease: Dietary fiber in sorghum, proso, and barnyard millet reduces LDL cholesterol and triglycerides while increasing HDL cholesterol; magnesium-rich millets lower blood pressure and ischemic stroke risk.
Type 2 diabetes: Polyphenols and fiber regulate postprandial glucose; meta-analyses show 36% lower GI vs. refined grains.
Cancer prevention: Dietary fiber, plant protease inhibitors, and bioactive peptides trigger apoptosis, inhibit cell proliferation, and interact with gut microbiota to produce anti-cancer effects.
Obesity: High protein and fiber content promote satiety, reduce caloric intake, and support weight management.
Osteoporosis: Finger millet's calcium content (344–364 mg/100 g) supports bone mineral density and reduces fracture risk.
Hypertension: Anti-hypertensive peptides and potassium in millets support vascular health.
Anemia: Pearl millet's iron content (>11 mg/100 g) and foxtail millet's iron help combat iron-deficiency anemia.
Gut disorders: Prebiotic fiber modulates gut microbiota, reducing colitis, IBD, and colorectal cancer risk.
