What are the different types of fatty acids?
On a molecular level, fatty acids are long chains of carbon atoms with some hydrogen atoms attached. Small differences in structure make a big difference in how fatty acids behave. There are four types of fatty acids: 1 Saturated: The carbon chains of saturated fats have no open spots on their chain for hydrogen atoms. That is why they are called saturated. They raise LDL cholesterol (the "bad" cholesterol) and increase the risk of heart disease 2 Monounsaturated : These fatty acids are missing one of their hydrogen atoms due to one double bond between carbon molecules. Sometimes called MUFAs, monounsaturated fats are healthier than saturated fats. 3 Polyunsaturated: These fatty acids are missing more than one of their hydrogen atoms. Sometimes called PUFAs, these fatty acids have significant health benefits. Omega-3 and omega-6 fatty acids belong to this group. 4 Trans fats : This type of fat is rare in nature but has been widely used in processed foods. Trans fats are created by adding hydrogen molecules to unsaturated fats to make them shelf-stable. Trans fats are generally unhealthy, and the Food and Drug Administration (FDA) regulates their use in food products.
