Oh My Omega: The Difference Between Omega-3, 6, and 9
The basics Let’s start by establishing an important fact: Fats are an essential component to a healthy diet. Whether you subscribe to vegan, paleo or omnivore eating styles, fat is your friend. Fats contribute to the flavor and texture of many foods, including oils, nuts, seeds, avocados, salmon and many more of what some consider the healthiest foods on the planet. Yet on a much deeper and molecular level, fats are critical to several essential functions in our bodies. Did you know that eating some types of fat can actually help reduce your cholesterol and risk for cardiovascular disease? It’s true. Here’s where it gets complicated Fats in our food are made up of fatty acid chains, which consist of carbon and hydrogen atoms linked together. There are two major types of fatty acids that we eat: saturated and unsaturated. Since dietary fats are a complex topic, we’ll save saturated fats and trans fat (which is technically an unsaturated fat) for another day. For now, let’s focus on unsaturated fats. Unsaturated fatty acids all have at least one double bond linkage between carbon atoms. These double bonds cause them to bend, kind of like how your arm bends at your elbow. This double bond limits the number of hydrogen atoms that can bind to the carbon atoms, so the molecule is not as saturated with hydrogen atoms as it could be. Thus, it’s considered “unsaturated.” Unsaturated fatty acids that have one double bond are called monounsaturated fatty acids (MUFAs). Unsaturated fatty acids with more than one double bond are called polyunsaturated fatty acids (PUFAs). Get it? “mono” for one and “poly” for many. Remember how I said fats were complex? Within the unsaturated fats are where we find the omega’s. Omega-3 and omega-6 fatty acids are PUFAs and omega-9 […]
