Omega-3 fatty acids are essential fats that your body cannot produce on its own. That means you need to get them through your diet. These healthy fats play an important role in supporting heart health, brain function, eye health, and reducing inflammation.
The three main types of omega-3s are:
- ALA (Alpha-Linolenic Acid): Found in plant foods like flaxseeds and walnuts.
- EPA (Eicosapentaenoic Acid): Primarily found in fatty fish.
- DHA (Docosahexaenoic Acid): Also found in fatty fish and is especially important for brain and eye health.
