What are Omega-3 Fatty Acids?

And why are they good for us? This article explores what Omega-3 fatty acids are and why we need them in our diet, alongside what foods contain Omega-3 fatty acids for you to incorporate into your diet.

Omega-3 Fatty Acids

Omega-3 fatty acids (are essential fats, ones that the body can’t make them from scratch so we must get them from food. Foods high in Omega-3 include oily fish (like Salmon + Mackerel), vegetable oils, nuts (especially walnuts), flax seeds, flaxseed oil, and leafy vegetables.

The Harvard School of Medical Health describe the importance of Omega-3 fats in their article:

"What makes omega-3 fats special? They are an integral part of cell membranes throughout the body and affect the function of the cell receptors in these membranes. They provide the starting point for making hormones that regulate blood clotting, contraction and relaxation of artery walls, and inflammation. They also bind to receptors in cells that regulate genetic function. Likely due to these effects, omega-3 fats have been shown to help prevent heart disease and stroke, may help control lupus, eczema, and rheumatoid arthritis, and may play protective roles in cancer and other conditions." Read more about it here

At Field Doctor we use oily fish, nuts, seeds and leafy vegetables and Salmon is one of our hero ingredients and it is truly supercharged with nutrition. Eating it has been associated with many health benefits.⁠ 

It is an excellent source of B12 - important for a healthy nervous system, blood cell function and making DNA.⁠

It contains high quality protein for muscle maintenance and growth. 

Full of omega-3 fatty acids - these are 'essential fatty acids' as your body cant make them but they play a critical role in heart health and brain health.⁠

Salmon also contains other minerals (such as potassium, selenium and iron) and is rich in a protective antioxidant, astaxanthin.⁠

Guidelines recommend all adults eat at least one portion of oily fish a week.⁠

Why not try our award-winning British Fish Pie, Salmon Teriyaki or Lean +Lighter Fish Pie?
