Abstract
Omega-3 fatty acids, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are critical for important physiological activities including foetal brain and infant eye development, lipid metabolism, and cognitive health. They also help guard against chronic diseases such as atherosclerosis, dementia, rheumatoid arthritis, and Alzheimer’s. Since these fatty acids cannot be synthesized predominantly in the body, their dietary supplementation is necessary, and the quest for affordable sources is a key focus of public health. Fish is a significant source of omega-3 polyunsaturated fatty acids (PUFAs) and offers a diverse range of options based on cost and availability. India, with its rich biodiversity, offers a diverse range of freshwater fish species with varying nutrient profiles. This review compiles recent data on omega-3 fatty acid content in Indian freshwater fish, highlighting species-specific variations, geographical differences, and environmental influences on fatty acid levels. It also focuses on the nutritional value of omega-3 fatty acids in Indian diets and public health. The overall objective of this review was to encourage further research and to advocate for the inclusion of high omega-3 fish in dietary guidelines.
