Functional Food Development Using Plant-Based Bioactive Compounds for Improved Metabolic Health

Abstract

Abstract

Metabolic disorders, including obesity, insulin resistance, dyslipidemia, and type 2 diabetes, are among the most pressing public health challenges of the 21st century. Conventional pharmacological approaches, while effective, are often associated with long-term side effects and limited accessibility. Functional foods enriched with plant-based bioactive compounds offer a complementary and preventive strategy for improving metabolic health. This study proposes a systematic framework for the development, characterization, and validation of functional foods formulated with polyphenols, flavonoids, dietary fibers, and plant sterols derived from selected botanical sources. A prototype plant-based nutritional formulation was developed and evaluated through in vitro antioxidant and anti-inflammatory assays, followed by a 12-week randomized controlled trial involving prediabetic participants. Results demonstrated significant improvements in fasting glucose, HOMA-IR index, LDL cholesterol levels, and inflammatory biomarkers compared to a control group. Mechanistic analyses revealed modulation of AMPK signaling and downregulation of pro-inflammatory cytokines. These findings highlight the translational potential of plant-derived bioactives in functional food design for metabolic health enhancement.
