Eat More Fish: The Benefits of Including Oily Fish in Your Diet
Eating fish regularly is one of the simplest and most effective ways to improve your diet and support overall health. Worldwide health authorities recommend that people should include at least two servings of fish in their diet each week, ensuring that one of those servings is oily fish. But why is fish so highly recommended, and what makes oily fish particularly beneficial?
Types of Fish and Oily Fish Explained
Fish are generally categorized into two types:
Cod, haddock, and pollock, which are types of white fish, contain minimal fat and are rich in protein.
Oily fish – including salmon, mackerel, sardines, anchovies, herring, and trout – have a higher fat content, but it’s largely the healthy omega-3 fats that bring a wealth of benefits.
Why Eat More Fish?
Fish is a nutritional powerhouse, offering several essential nutrients, including:
High-quality protein – vital for muscle maintenance and repair
Vitamin D plays a crucial role in ensuring proper bone health and bolstering the immune system.
Iodine – supports thyroid function
Selenium functions as an antioxidant, protecting cells from injury.
Benefits of Oily Fish
Oily fish are especially rich in omega-3 fatty acids—namely EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—which play crucial roles in many body functions.
Here are the essential health benefits associated with oily fish:
1. Heart Health
Omega-3s are known to reduce the risk of heart disease by:
Lowering blood pressure
Reducing triglyceride levels
Decreasing the risk of abnormal heart rhythms
Slowing the build-up of plaque in arteries
2. Brain Function
DHA serves as a significant structural fat within the brain.
• Consistent intake of oily fish correlates with:

Lower risk of dementia and Alzheimer’s disease
Improved mental health, including reduced risk of depression
3. Joint and Eye Health
Omega-3 fatty acids help:
Reduce inflammation in joints, easing symptoms of arthritis
Shield yourself from age-related macular degeneration, a significant factor in vision loss.
4. Pregnancy and Child Development
Omega-3s are vital during pregnancy for:
Brain and eye development of the baby
Potentially lowering the risk of premature birth
How Much Should You Eat?

At least two portions (about 140g each) of fish per week
At least one of those should be oily fish
