11 Important Benefits of Fish Oil, Based on Science
1. May Support Heart Health
Fish oil is an excellent source of omega-3s, which is good for the heart and the brain. Research shows that people who eat a lot of fish have much lower rates of heart disease. Multiple risk factors for heart disease appear to be reduced by consuming fish or fish oil. The benefits of fish oil for heart health include helping to lower cholesterol, lower triglycerides, reduce blood pressure, and prevent the formation of plaques that harden arteries.
2. May Help Treat Certain Mental Health Conditions
If you measure the weight of the brain without any fluid, it will contain about 20% polyunsaturated fatty acids, which include omega-3s. Therefore, omega-3s are essential for typical brain function. In fact, research suggests that people with certain mental health conditions have lower omega-3 blood levels, and having more omega-3s may help prevent the onset or improve the symptoms of some mental health conditions like depression.
3. May Support Eye Health
Evidence shows that people who don’t get enough omega-3s have a greater risk of eye diseases, with the exception of dry eye disease. Furthermore, eye health begins to decline in old age, which can lead to age-related macular degeneration (AMD). Eating fish is linked to a reduced risk of AMD, but the results from fish oil supplements are less convincing.
4. May Reduce Inflammation
Because fish oil has anti-inflammatory properties, it may help treat chronic inflammatory conditions. For example, increased weight or stress can sometimes contribute to higher levels of inflammation. When it comes to inflammatory bowel disease (IBD), however, the role of omega-3 still isn’t fully determined.
5. May Support Healthy Skin
Your skin is the largest organ in your body, and it contains a lot of omega-3 fatty acids. Research suggests that omega-3 may help with reducing symptoms of atopic dermatitis, which is a chronic skin condition characterized by inflammation, itching, and dryness.
6. May Help Prevent ADHD
Fish oil supplements may improve perceived hyperactivity, inattention, impulsiveness, and aggression in children. This may benefit early life learning. However, more research is needed to confirm this effect.
7. May Support Brain Function
People who eat more fish tend to experience a slower decline in brain function in old age. According to a 2023 meta-analysis of 48 studies, omega-3 supplements may help reduce the risk of dementia and age-related cognitive decline by as much as 20%.
8. May Improve Bone Health
Calcium and vitamin D are very important for bone health, especially in older age, but some studies suggest that omega-3 fatty acids can also be beneficial. People with higher omega-3 intakes and blood levels may have better bone mineral density (BMD).
9. May Help Prevent Symptoms of Mental Decline
According to a 2023 meta-analysis of 48 studies, omega-3 supplements may help reduce the risk of dementia and age-related cognitive decline by as much as 20%.
10. May Improve Asthma Symptoms and Allergy Risk
Research suggests that omega-3 may help with reducing asthma-related inflammation, the severity of symptoms, and even the need to use asthma medications.
11. May Support Overall Health
Omega-3s contribute to typical brain and eye development. They fight inflammation and may help prevent heart disease and a decline in brain function. Because fish oil contains a lot of omega-3s, people who are at risk of these health conditions can benefit from taking it.
Conclusion
In conclusion, fish oil is a valuable supplement that offers numerous benefits for overall health. From supporting heart health to improving brain function, fish oil is an excellent addition to a healthy diet.
