Omega-3 fatty acids are essential polyunsaturated fats that the body cannot produce on its own, so they must be obtained from diet or supplements. They are crucial for heart, brain, and overall health. Here’s a detailed overview:
🌱
Types of Omega-3 Fatty Acids
- ALA (Alpha-linolenic acid) – found in plant sources like flaxseeds, chia seeds, walnuts, and soy.
- EPA (Eicosapentaenoic acid) – found in fatty fish like salmon, mackerel, sardines, and fish oil.
- DHA (Docosahexaenoic acid) – found in fatty fish and algae; essential for brain and eye health.
