What are Omega-3 Fatty Acids?
Definition of Omega-3 Fatty Acids
Omega-3 fatty acids are a type of polyunsaturated fat that play a crucial role in maintaining your overall well-being. These fats are called “Omega-3” because the first double bond in the fatty acid chain is located three carbon atoms away from the methyl group at the end of the chain. This unique structure gives Omega-3 fatty acids their characteristic properties and health benefits.
Types of Omega-3 Fatty Acids
There are three main types of Omega-3 fatty acids that are most commonly found in food and have been well-studied for their health benefits. These are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Each of these fatty acids has its own distinct functions and benefits in the body, making it important to consume a variety of Omega-3 sources to ensure optimal health.
Sources of Omega-3 Fatty Acids
Omega-3 fatty acids can be obtained from both plant-based and animal-based sources. Some of the best plant-based sources include flaxseeds, chia seeds, hemp seeds, walnuts, and leafy green vegetables. On the other hand, fatty fish like salmon, mackerel, sardines, and trout are excellent sources of EPA and DHA, while ALA is found in plant-based sources like flaxseed oil, soybean oil, and canola oil. It is important to include a variety of these sources in your diet to ensure an adequate intake of Omega-3 fatty acids.
