According to research conducted at Harvard University, omega-3 fatty acid deficiency is officially one of the top 10 causes of death in America, claiming the lives of up to 96,000 people each year. Out of the 12 dietary, lifestyle and metabolic risk factors examined in the study, omega-3 fatty acid deficiency ranked as the sixth highest killer of Americans. (1) These deaths are considered preventable since getting enough omega 3-fatty acids in your diet can ward off this now common cause of death, and fish oil benefits omega-3 intake as a potent omega-3 source.
The fish oil benefits include decreasing the risk of heart disease and stroke while also helping reduce symptoms of depression, hypertension, attention deficit hyperactivity disorder (ADHD), joint pain, arthritis and chronic skin ailments like eczema. (2) Fish oil intake has also been associated with aiding the body in weight loss, fertility, pregnancy and increased energy. Prescription fish oil has even been approved by the FDA to lower unhealthy high triglyceride levels. (3)
Most of the fish oil benefits exist because it’s one of nature’s richest sources of omega-3 fatty acids. While certain fish oil claims aren’t accurate, I will go over the proven scientific evidence that demonstrates the true benefits of fish oil.
Omega-3 essential fatty acids consist primarily of, particularly, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). A 2014 study in Nutrition Journal showed that the majority of Americans do not consume enough essential fatty acids in their diet. These important nutrients can be found in a variety of food sources, which include fish (mackerel, cod, and salmon are among the richest), walnuts, chia seeds, flax seeds, hemp seeds, avocado, and natto.
A 2017 study in Future Science showed omega-3 fish oils can reduce the inflammation leading to heart disease. Another study from the same year in Atherosclerosis showed that higher levels of omega-3 in the blood could reduce death from heart disease by 30 percent.
Drug companies manufacture and sell pharmaceutical-grade fish oil, which has been shown to lower triglyceride levels by 50 percent. However, non-pharmaceutical fish oil capsules appear to provide the same benefit at a fraction of the cost.
Suggested dose: Omega-3 fish oil 1,000 to 4,000 mg daily
