Fish Oils and Omega-3 Oils – Benefits, Foods, and Risks

Overview

Over the past decade, the consumption of nutrition supplements, like Omega-3 Fatty Acids, has gained prominence in promoting and maintaining an active lifestyle among health-conscious individuals. 

Nutritional deficiencies due to poor diet habits are on the rise, especially among working professionals. For instance, IT professionals are prone to Vitamin D deficiency due to their work largely being indoors. As a result, the consumption of nutritional supplements has become an alternative way for working professionals to stay healthy and active, and avoid certain lifestyle diseases. 

What are Omega-3 fatty acids?

Omega-3 fatty acids are essential fatty acids that are vital for the normal functioning of internal organs, like the brain and retina. People need to rely on food sources (like fish) or supplements because the human body cannot create these fatty acids on its own.

Fatty acids found in Omega-3 supplements have also been found to be highly beneficial in improving cardiovascular health and preventing the onset of heart diseases. 

Two crucial fatty acids called  EPA and DHA  are found primarily in certain fish. Another omega-3 fatty acid, ALA (alpha-linolenic acid), is found in plant sources such as nuts and seeds.

Where to Get Omega-3s?

It is good to get omega-3 fatty acids from foods rather than supplements.  It is good to consume non-fried oily fish high in DHA and EPA omega-3 fatty acids at least two times a week.

These include:

• Anchovies
• Bluefish
• Herring
• Mackerel
• Marlin
• Orange roughy
• Salmon
• Sardines
• Sturgeon
• Lake trout
• Tuna

Avoid fish that may have higher levels of mercury, polychlorinated biphenyls (PCBs), or other toxins such as mackerel, shark, wild swordfish, and tilefish. Fish like wild salmon and wild trout are safer.

Good food sources of ALA include:

• Flaxseed and flaxseed oil
• Walnuts
• Chia seeds
• Soybean oil 
• Canola oil

These may however be high in calories.
