By including a variety of healthy fats in our diet, we can help to support overall health and wellbeing, and reduce the risk of chronic diseases such as heart disease and type 2 diabetes.
What are the best sources of omega-3 fatty acids?
Omega-3 fatty acids are an essential type of polyunsaturated fat that play a critical role in heart health, brain function, and inflammation regulation. The best sources of omega-3 fatty acids are fatty fish such as salmon, sardines, and mackerel, which are rich in EPA and DHA, two types of omega-3s that are readily absorbed by the body. Other sources of omega-3s include flaxseeds, chia seeds, and walnuts, which contain ALA, a type of omega-3 that must be converted to EPA and DHA in the body.
While plant-based sources of omega-3s can provide some benefits, they are not as readily absorbed by the body as the omega-3s found in fatty fish. Therefore, it’s recommended to consume fatty fish at least 2-3 times per week, or consider taking an omega-3 supplement if we don’t eat fish or are at risk of deficiency. Additionally, it’s also important to maintain a balanced intake of omega-6 fatty acids, which are found in vegetable oils and other foods, as an imbalance of omega-6 and omega-3 fatty acids can lead to inflammation and other health problems. By consuming a variety of omega-3 rich foods and maintaining a balanced intake of essential fatty acids, we can help to support heart health, brain function, and overall wellbeing.
