Omega-3 fatty acids are a class of essential polyunsaturated fats that are important for various aspects of human health. These fats are considered essential because the human body cannot synthesize them on its own and must obtain them from dietary sources.
The primary types of health-related omega-3 fatty acids are Alpha-Linolenic Acid (ALA), Eicosapentaenoic Acid (EPA), and Docosahexaenoic Acid (DHA). High ALA foods are flaxseeds, chia seeds, walnuts, and hemp seeds. High EPA and DHA foods are fatty fish like salmon, mackerel, and sardines.
Key health benefits:

Brain Health: DHA is crucial for brain development in infants and cognitive function in adults, may help improve conditions like depression and anxiety.
Eye Health: DHA is an essential component of the retina, and its intake is important for maintaining good vision and reducing the risk of age-related macular degeneration.
