The rise of plant-based milk alternatives: exploring nutritional, health, and sustainability impacts

The rising demand for plant-based milk alternatives (PBMAs) reflects growing consumer interest in sustainable nutrition and healthier diets. This review provides a comprehensive examination of the nutritional quality, health impacts, and sustainability of PBMAs derived from cereals, legumes, nuts, and seeds. It analyzes their physicochemical characteristics, fortification strategies, and advancement in processing technologies, including high-pressure homogenization, ultrasonication, and enzymatic treatments, which enhance shelf life, sensory quality, and bioavailability. This review also explores allergenicity and antinutritional factors associated with PBMAs, highlighting the role of formulation and processing in addressing these limitations. In addition, it discusses global market trends, consumer perceptions, and regulatory considerations, underscoring the role of PBMAs in shaping sustainable and resilient food systems. By addressing knowledge gaps across nutrition, processing, and sustainability, this review provides valuable insights for researchers, industry professionals, and policymakers seeking to optimize PBMAs for a growing, health-conscious, and eco-aware global population. • Explores nutrition and sustainability of plant-based milk alternatives. • Evaluates processing methods for quality and fortification of PBMAs. • Examines allergenicity and antinutritional factors in plant-based milks. • Analyzes global market trends and consumer perceptions of PBMAs. • Provides insights for creating nutritious, sustainable plant-based milks.
