Case in point: omega-3 fatty acids, known as "healthy fats." They're packed with health benefits, from lowering your risk for heart disease to helping with anxiety.
They're found in many food sources, though you can also choose from over-the-counter omega-3 supplements.
But like any trendy health food, omega-3 fatty acids are surrounded by hype.Unlike other fats that the body is capable of synthesizing (called non-essential fatty acids), omega-3s can't be made from scratch.
There are three main types of omega-3 fatty acids:.The first two types (EPA and DHA) are abundant in fish, which is why they're commonly called "marine omega-3s." The third type (ALA) is common in a variety of food sources, including certain oils, nuts, leafy vegetables and some meats.
Scientists have noted a variety of benefits that may be associated with omega-3 fatty acids.A wide array of studies has shown a connection between heart health and omega-3 fatty acids.Because of the connection between omega-3s and general brain health, it's perhaps no surprise that some research supports that these fats may slow cognitive decline as we age.Scientists are still studying these and many other benefits of omega-3 fatty acids, including their effect on ADHD, metabolic syndrome and certain autoimmune diseases.Generally, doctors recommend that you get most or all of your omega-3 fatty acids from food sources.Omega-3 supplements, such as fish oil or cod liver oil, offer many of the same benefits as getting these fats through food sources, though.Ideally, it's best to do this through sources such as fish, walnuts, flaxseed oil and other foods that are rich in omega-3 fatty acids.
