Omega-3 Fatty Acids: Why They Still Matter

Overview

While current research suggests that omega-3 fatty acids may not directly alleviate symptoms of knee osteoarthritis, they remain a vital component of a healthy diet. Their broader anti-inflammatory properties and systemic health benefits make them worth including in your nutritional strategy.

What Are Omega-3s?

Omega-3 fatty acids are a type of polyunsaturated fat found in certain plant sources, seafood, and to a lesser extent, eggs and meat. Because our bodies can’t produce them naturally, they’re classified as essential nutrients, meaning we must obtain them through our diet.

Why Are They Important?

Omega-3s are highly concentrated in the brain, where they support:

•        Cognitive development and function
•        Mood regulation and behavioural health
•        Skin and hair growth
•        Bone and reproductive health
•        Metabolic balance
  
  

Even though supplements offer a convenient way to meet daily requirements (around 500mg per day), whole food sources are generally preferable. They’re more cost-effective and reduce the risk of issues like oil oxidation or unpleasant fishy odours often associated with lower-quality supplements. If you do opt for supplements, Consumer group Choice (www.choice.com.au) provides helpful guidance on selecting high-quality fish oil products.

Best Sources of Omega-3s

To naturally boost your intake, consider incorporating the following into your weekly routine:

•        Oily fish (e.g., sardines, salmon): Aim for 2–3 servings per week
•        High-quality fish oil supplements (if needed)
•        Ground linseeds (flaxseeds) and linseed oil
•        Mixed raw nuts
•        Avocado (limit to ¼ per day if managing weight)
