Fish oils come from fatty fish, also known as oily fish, specifically the tissue of fatty fish, such as trout, mackerel, tuna, herring, sardines, and salmon.
Fish oils are of interest to nutritionists and health care professionals because of two main ingredients: DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid) - both types of Omega-3 fatty acids.
The fillets of oily fish contain up to 30% oil; this figure may vary. White fish, on the other hand, only contain high concentrations of oil in the liver, and have much less oil. Apart from omega-3 fatty acids, oily fish are also good sources of vitamins A and D. Whitefish also contain these nutrients, but at much lower concentrations.
Health experts commonly tell people that oily fish have more health benefits than white fish. However, their recommendations have never been compellingly proven scientifically in large population studies.
Many health authorities around the world advise people to consume either plenty of oily fish or to take supplements, because of their supposed health benefits. Studies over the last ten years have produced mixed results regarding the benefits of the dietary intake of fish oils.
Some people confuse fish oils and cod liver oil - they are different. Fish oils are extracted from the tissue of deep sea oily fish such as tuna, mackerel, herring and salmon. Cod liver oil, by contrast, is extracted solely from the livers of cod. Fish oils contain higher amounts of omega-3 fatty acids than cod liver oil, but lower amounts of vitamins A and D.
Over the last ten years, there have been dozens of studies on fish oils and omega-3 oils. Some have backed up these claims, while others have not.
Fish oils are said to have a number of health benefits if they are included in a human diet. You can read the full article for a list of the benefits Here
According to a recent study at Harvard University – omega-3 fatty acid deficiency is officially one of the top 10 causes of death in America.
"Fish oil benefits are used in the treatment of many health issues including: heart disease, ADHD, anxiety, depression, high cholesterol, inflammatory bowel disease, arthritis, alzheimer’s disease, eczema, diabetes, cancer, weakened immunity, autoimmune disease and macular degeneration.
Also, it’s been proven to aid the body in weight loss, fertility, healthy pregnancy, healthy skin and increased energy.
Most of the health benefits of fish oil are because it is one of natures’ richest sources of omega-3 fatty acids like Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA).
While fish oil benefits are numerous there are some false claims on how to use this incredible supplement but in this article we will go over the proven scientific evidence to demonstrate the true benefits of fish oil.
Omega-3 Deficiency Side Effects
Many of Americans’ health problems can be traced back to having an imbalance of omega-3 and omega-6 fats. Omega-6 fats aren’t necessarily bad for you but if they are consumed in large amounts without omega-3’s they cause inflammation which leads to chronic illness.
Today, the average american has a 20:1 ratio of omega-6 to omega-3 fats, when a healthy ratio is more ideally around 2:1. This shows just how deficient most of us are and why supplementing with fish oil is so beneficial.
The biggest cause of omega-3 deficiency is the overconsumption of fried foods, fast foods and boxed foods that contain vegetables oils like soybean oil, canola oil, cottonseed oil and corn oil.
If you have an omega-3/6 imbalance it can lead to the following health conditions:
• Autoimmune disease
• Heart disease
• Type II diabetes
• Irritable bowel syndrome
• Metabolic syndrome
• Macular degeneration
It’s also important to know that even though certain other foods like flaxseeds and grass-fed beef contain omega-3 fats, those omega’s are ALA and not EPA/DHA like what is found in fish oil. According to the medical research there are far more health benefits in fish oil (EPA/DHA) than flax oil (ALA) for most people." For the full article, click Here
Fish oil has some proven/studied benefits, but like for every supplement it is always advised to consult a doctor.
