16 Foods High In Omega 3

Omega-3 is the name for a group of polyunsaturated fatty acids and considered one of the “heart healthy” types of fats. They’re named after their chemical structure, and are different to Omega-6 fatty acids. The heart-healthy omega-3 fatty acids have been shown to help reduce inflammation, and may support healthy ageing.1

Three primary Omega-3 fatty acids are common in foods – eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA — commonly found in fish and shellfish)=, and alpha-linolenic acid (ALA), which is typically found in plants.1 This article presents the some of the best food sources of omega-3 fatty acids to help you increase your consumption.

Take home message

While we know there are many health benefits to omega-3 fatty acids, it can be challenging to remember which foods contain the most of these heart-healthy fats. Focusing on fish and some plant-based foods like soybeans and kidney beans can help contribute to a heart-healthy diet. In addition to a healthy diet, some people may choose to take an Omega-3 supplement to ensure their intake is sufficient.
