Which category of fatty acids includes Omega-3?

The category of fatty acids that includes Omega-3 is polyunsaturated fatty acids. Omega-3 fatty acids are essential fats that the body cannot produce on its own, so they must be obtained through diet. They are characterized by having multiple double bonds in their carbon chain, which is a defining feature of polyunsaturated fats.

Polyunsaturated fatty acids play a crucial role in heart health, brain function, and overall well-being. They can be found in various food sources, such as fish, flaxseeds, walnuts, and certain plant oils. Omega-3 specifically has been associated with reducing inflammation, lowering the risk of chronic diseases, and supporting cardiovascular health.

In contrast, saturated fatty acids are typically solid at room temperature and found in animal fats and some plant oils. These fats do not contain double bonds and are often linked to higher levels of LDL cholesterol in the blood. Trans fatty acids are artificially created through hydrogenation and are known to have negative health impacts, including raising LDL cholesterol levels and lowering HDL cholesterol. Monounsaturated fatty acids, while also healthy and beneficial for heart health, only contain one double bond in their structure, distinguishing them from polyunsaturated fatty acids which contain two or more.
