Title : Agricultural By-product for Nutrition Security: The Case of Corn Silk
Abstract:
This research advocates for a paradigm shift in how agricultural byproducts are perceived, positioning corn silk as a vital player in the global effort to achieve sustainable nutrition. Its transformation from waste to super food exemplifies the intersection of health, sustainability, and innovation, paving the way for broader applications in functional foods and nutraceuticals. The global challenge of achieving sustainable nutrition and combating non-communicable diseases necessitates innovative approaches that maximize the health benefits. Corn silk, the delicate strands found within maize husks, is often discarded as waste despite its rich nutritional profile and bioactive potential. This research explores the transformation of corn silk into a nutrient-dense super food, emphasizing its implications for human health and sustainable nutrition. Corn silk is a natural reservoir of macronutrients (16.9g/100 g protein) and micronutrients along with excellent dietary fiber content (52.2 g/100 g). These components are associated with significant health benefits, including potent antioxidant (10.18 mg TE/100g) and anti-inflammatory properties that combat oxidative stress and inflammation, two underlying factors in many chronic diseases. Corn silk also exhibits hypoglycemic effects (pGI 57.6), making it valuable for managing diabetes, and has been shown to support kidney health through its diuretic and nephroprotective properties. Its ability to regulate blood sugar levels may also help control hunger and prevent overeating, supporting weight loss efforts. Emerging studies further suggest its role in regulating blood pressure and enhancing immune function, making it a holistic addition to functional foods. The research also focuses on practical applications of corn silk, highlighting its potential in developing herbal tea and tinctures, nutraceutical supplements, and dietary powders. Corn silk, rich in dietary fiber and bioactive compounds, offers potential benefits for managing constipation. Its high fiber content helps relieve constipation by improving bowel movement regularity and supporting gut health. Additionally, corn silk's diuretic properties aid in reducing bloating and water retention, contributing to a feeling of lightness. Furthermore, its prebiotic effects may improve gut micro biota, enhancing metabolism and satiety. This research underscores the need to repurpose agricultural waste like corn silk, not only to reduce waste but also to contribute to global nutritional security and health. By offering an affordable, nutrient-rich resource, corn silk can provide economic opportunities for farmers and the food processing industry while promoting sustainable agricultural practices.
