Identifying the Richest Source of ω-3 Fatty Acids

Omega-3 fatty acids ($\omega$-3) are essential polyunsaturated fats crucial for health. Identifying the food richest in these specific fatty acids is key for dietary planning.

Nutritional Comparison of Food Sources

Let's analyze the options provided:

• Coconut: Primarily rich in saturated fats, not significant amounts of ω-3.
• Flax seed: An excellent source of Alpha-linolenic acid (ALA), a type of ω-3 fatty acid.
• Olives: Mainly known for monounsaturated fats, with minimal ω-3 content.
• Groundnut (Peanut): Contains mostly monounsaturated and some polyunsaturated fats, but is not a primary source of ω-3 compared to flax seeds.

Conclusion on ω-3 Rich Foods

Among the choices, Flax seed stands out as the richest dietary source of ω-3 fatty acids, particularly ALA.
