Interestingly, the results are also consistent with our recent findings that somatic anxiety is associated with omega-3 PUFA deficits and the genetic risks of PUFA metabolic enzyme cytosolic phospholipase A2 in major depressive disorder62,63 and interferon α–induced neuropsychiatric syndrome.63,64 Brain membranes contain a high proportion of omega-3 PUFAs and their derivatives and most animal and human studies suggest that a lack of omega-3 PUFAs in the brain might induce various behavioral and neuropsychiatric disorders,16,65-70 including anxiety-related behaviors.12,18,19,32,49,71 Emerging evidence suggests that omega-3 PUFAs interfere with and possibly control several neurobiological processes, such as neurotransmitter systems, neuroplasticity, and inflammation,12,72 which is postulated to be the mechanism underlying anxiety and depression.
Bo and I worked with Dr. Harris many years ago to measure the impact of eating one Omega Cookie® daily on the study participants’ omega-3 index levels, and we recently ran into him at ISFFAL. At the conference, we remeasured our omega-3 index and omega-6/omega-3 ratios, and a few weeks later, we got our results in the mail. For the two of us, it was exciting to get another concrete measure of how our daily omega-3 consumption impacted our scores. For the record, we take one vial of Omega Restore™ per night and frequently sneak an Omega Heaven® or Omega Cookie during the day.
In many cases, people are recommended to consume fish oil because it is an easy way to get additional omega-3 fatty acids into their diet. Omega-3 fats can be used to reduce swelling or to prevent blood clots which could cause major cardiovascular damage. There are many other conditions which can be decreased or improved with the use of fish oil. In most cases fish oil is used to help reduce high triglycerides which can cause serious conditions like diabetes or heart disease.
In recent years, many people – particularly those who strictly follow a vegetarian or vegan diet – have believed that they do not have to consume animal products to get omega-3s, as long as they are consuming high amounts of plant-based omega-3s. But, as I mentioned before, most of the health benefits that you can get from omega-3 fats are linked to animal-based EPA and DHA fats – not plant-based ALA. They are simply NOT interchangeable.
Alpha-linolenic Acid (ALA): This plant-based omega-3 is found in green, leafy vegetables, flaxseeds, chia seeds and canola, walnut and soybean oils (although those rancid oils are not ones I generally recommend). ALA is known as a short-chain omega-3, meaning your body has to convert it into longer-chained EPA and DHA to synthesize it. This process is rather inefficient and only about one percent of the ALA you consume is converted to the long-chain version your body needs (although this percentage is slightly higher for women).
The Federal Government’s Dietary Guidelines for Americans 2015–2020 recommends that adults eat 8 or more ounces of a variety of seafood (fish or shellfish) per week for the total package of nutrients seafood provides, and that some seafood choices with higher amounts of EPA and DHA be included. Smaller amounts of seafood are recommended for young children.
2. Omega-3 normalizes and regulates your cholesterol triglyceride levels. Compared to a statin, both fish oil and krill oil are more efficient in doing this. According to a study comparing the efficiency of krill and fish oils in reducing triglyceride levels,7 both oils notably reduced the enzyme activity that causes the liver to metabolize fat, but krill had a more pronounced effects, reducing liver triglycerides significantly more.
Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body, and have other health benefits, such as treating hypertriglyceridemia, although claims of preventing heart attacks or strokes have not been supported. Fish oil and omega-3 fatty acids have been studied in a wide variety of other conditions, such as clinical depression, anxiety, cancer, and macular degeneration, yet benefits in these conditions have not been verified.
