Be a Sardine Queen (or King): The Power of Omega-3 Fatty Acids for Your Eyes
Posted: 23/05/2025
When it comes to taking care of your health, most of us know the importance of eating a balanced diet. But did you know that adding a regular dose of Omega-3 fatty acids to your meals can benefit not just your heart, but also your eyes? One of the easiest and most affordable ways to get these essential nutrients is by making tinned sardines or mackerel a part of your weekly routine. These small fish are packed with Omega-3s, and their health benefits are profound, especially when it comes to maintaining good vision.
At Rawlings Opticians & Hearing Care, we believe that eye health is something you can support with the right diet and lifestyle. So, we’re encouraging you to “Be a Sardine Queen (or King)” and add more Omega-3 fatty acids to your diet for the benefit of your eyes and overall health.
What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are essential fats that our body cannot produce on its own. These fats play a crucial role in reducing inflammation, improving brain function, and supporting cardiovascular health. There are three main types of Omega-3s: ALA (alpha-linolenic acid), found in plant-based sources like flaxseeds and walnuts; EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are found in oily fish like sardines, mackerel, and salmon.
When it comes to eye health, DHA and EPA are the stars. DHA is a major structural component of the retina, the part of the eye responsible for vision. It helps protect your retina from damage and supports its function in low-light conditions. EPA, on the other hand, works to reduce inflammation in the body, which can also benefit eye health by protecting against conditions like dry eyes and age-related macular degeneration (AMD).
The Eye Health Benefits of Omega-3s
Incorporating Omega-3-rich foods into your diet is one of the most proactive things you can do for your eye health. Studies have shown that Omega-3s can help in the following ways:
- Protect Against Dry Eye Syndrome: Omega-3 fatty acids are known to support the tear glands and improve the quality of the tears produced. This can be especially beneficial for people who suffer from dry eye syndrome, a condition where the eyes don’t produce enough moisture to keep them comfortable.
- Reduce the Risk of Age-Related Macular Degeneration (AMD): AMD is a leading cause of blindness in older adults, and research has shown that Omega-3s may help prevent the progression of this condition by protecting the retina and reducing inflammation.
- Support Healthy Retinal Function: DHA is a key component of the retina, and adequate levels of DHA in the diet may help maintain the health of this vital organ, improving visual function and night vision.
- Lower the Risk of Cataracts: Some studies have suggested that Omega-3s might help prevent or delay the development of cataracts by combating oxidative stress, which can damage the lenses of the eyes.
How to Fit Sardines and Mackerel into Your Diet
One of the best things about sardines and mackerel is that not only are they incredibly nutritious, they are both very affordable compared to other types of fish – and easy to prepare. While fresh fish can be pricey, tinned sardines and mackerel are budget-friendly, shelf-stable, and just as nutritious. Tinned fish is also more sustainable, as sardines and mackerel are smaller fish that are lower on the food chain, meaning they have a smaller environmental impact than larger fish like tuna. Ideally, you should aim for 2-3 servings of oily fish per week, and here are a few simple ways to get those servings in:
- Sardine Sandwich: A sardine sandwich is an easy and delicious lunch option. Just mash up a can of sardines (in olive oil or water) and spread on whole-grain bread. Add a squeeze of lemon, a handful of spinach, or some sliced cucumber for extra crunch and nutrients.
- Sardines on Toast: This is a classic comfort meal that takes just a few minutes to prepare. Simply top a slice of whole-wheat toast with sardines and a sprinkle of pepper. For an extra touch, you can drizzle with olive oil and add a few fresh herbs.
- Mackerel Salad: A mackerel salad is a perfect way to enjoy a light, yet filling meal. Toss some tinned mackerel with mixed greens, cherry tomatoes, and your favorite vinaigrette for a healthy, Omega-3-packed dish..
- Sardine and Tomato Salad: Combine tinned sardines with fresh tomatoes, red onions, a splash or red wine vinegar and olives for a Mediterranean-inspired dish. Drizzle with olive oil, lemon juice, and a pinch of oregano for a burst of flavor.
- Mackerel Pate: Whizz in a food processor 2 tins of mackerel in oil, a healthy splash of lemon juice, half a tub of crème fraiche,a tablespoon of Dijon mustard and salt and pepper to taste. Add more crème fraiche if you prefer a creamier pate. Serve with whole-grain crackers or fresh vegetables for dipping.
- Sardine Bolognese: Fry until soft in 2 tbsp olive oil: 1 chopped onion, 2 cloves of garlic, 2 finely chopped carrots, 3 sticks of finely chopped celery, 200g of mushrooms a pinch of chilli flakes (if desired). Add 2 tins chopped tomatoes and a tablespoon of dried oregano flakes then simmer down until thickened. Add 2 tins of sardines in tomato sauce and gently break apart the sardines into chunks. Season to taste and serve with your favourite pasta.
To sum up, adding Omega-3-rich sardines and mackerel to your diet is an easy, affordable, and delicious way to support your overall health, particularly your eye health. With the convenience of tinned fish, there’s no excuse not to “be a Sardine Queen (or King)” and make these little fish a regular part of your meals.
