Omega-3 fatty acids are crucial for optimal health. These fats are essential to the body and must be sourced from the diet as the human body can’t produce them on its own.
Omega-3 fats have been associated with numerous health benefits including reducing inflammation, improving heart health, and even preventing certain diseases. In this article, we’ll explore the role of omega-3 fats in preventing various diseases.
What are Omega-3 Fats?
Omega-3 fats are a family of polyunsaturated fatty acids that play numerous roles in the body. The three types of omega-3 fats include:.
- Eicosapentaenoic Acid (EPA)
- Docosahexaenoic Acid (DHA)
- Alpha-linolenic acid (ALA)
EPA and DHA are largely found in fatty fish and shellfish, while ALA is found in plants like flaxseeds, chia seeds, and walnuts.
Omega-3 Fats and Heart Health
One of the most widely researched benefits of omega-3 fats is their impact on heart health. Studies have found that omega-3 fats can reduce triglycerides, lower blood pressure, and reduce the risk of heart disease and stroke.
One study published in the Journal of the American Medical Association found that consuming omega-3 fats from fish oil reduced the risk of sudden cardiac death by almost 50%.
Another study published in the Journal of Nutrition found that consuming omega-3 fats improved blood flow and heart rate variability, which are important markers of heart health.
Omega-3 Fats and Inflammation
Inflammation is a natural response to injury or infection, but chronic inflammation can lead to numerous health problems such as arthritis, diabetes, and heart disease.
Omega-3 fats have anti-inflammatory properties and can help reduce chronic inflammation in the body.
One study published in the Journal of the American College of Cardiology found that supplementing with omega-3 fats reduced markers of inflammation in the body and improved heart function.
Another study published in the Journal of Clinical Endocrinology and Metabolism found that consuming omega-3 fats improved insulin sensitivity and reduced inflammation in overweight and obese adults.

Another study published in the International Journal of Cancer found that consuming omega-3 fats reduced the risk of colorectal cancer in women.
Omega-3 Fats and Brain Health
Omega-3 fats are also important for brain health. DHA, in particular, is a major component of brain cell membranes and is essential for brain function.
Studies have found that consuming omega-3 fats can improve cognitive function, reduce the risk of Alzheimer’s disease, and improve mood.
One study published in the Journal of Neurochemistry found that supplementing with omega-3 fats improved cognitive function in older adults with mild cognitive impairment.
Another study published in the Journal of Affective Disorders found that supplementing with omega-3 fats reduced symptoms of depression in adults.
How to Get Omega-3 Fats in Your Diet
The best sources of omega-3 fats are fatty fish and shellfish. Some of the best sources include:.
- Salmon
- Tuna
- Mackerel
- Sardines
- Trout
- Oysters
Plant-based sources of omega-3 fats include flaxseeds, chia seeds, and walnuts. However, these sources contain ALA which your body must convert to EPA and DHA in order to reap the benefits.
Final Thoughts
Omega-3 fats are essential for optimal health and have been associated with numerous health benefits. From reducing inflammation to improving heart health, there are plenty of reasons to ensure you’re getting enough omega-3s in your diet.
