Fatty acids are an essential part of our diet. They play diverse roles in maintaining health and overall well-being. Among the many types of fatty acids, omega-3 fatty acids stand out due to the distinct health benefits that they offer. These fatty acids are important for many bodily functions including the alleviation of inflammation and improved brain function.
However, despite their importance, many people do not consume enough omega-3 fatty acids. In this article, we will explore the importance of omega-3 fatty acids and their must-have food sources to incorporate into your diet.
What are omega-3 fatty acids?
Omega-3 fatty acids are healthy fats and a type of polyunsaturated fat. They are termed essential because they are a part of the structure of every cell in the body and are involved in various functions. They help maintain the functions of the heart, blood vessels, and lungs, boost energy levels, and enhance the functions of the immune system.
There are three major types of omega-3 fatty acids: alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). These fatty acids all aid different functions in the body. For example, the body uses alpha-linolenic acid (ALA) as an energy source; docosahexaenoic acid (DHA), on the other hand, is a structural component of the brain and is important for brain development, vision, and cognition; and eicosapentaenoic acid (EPA) helps to reduce inflammation in the body. Each type of omega-3 fatty acid plays a specialized role in the body to promote overall health.
Omega-3 fatty acids and nutrition
Although omega-3 fatty acids are essential for well-being, the human body cannot produce them on its own because our bodies lack the enzymes needed for their synthesis. This is why it is necessary to consume foods rich in omega-3 fatty acids as a part of a balanced diet.
There are diverse foods from which one can obtain different kinds of omega-3 fatty acids. Alpha-linolenic acid (ALA) is a plant-based omega-3 fatty acid and can be obtained from plant oils, seeds, and nuts. Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are predominant in fatty fish like mackerel and sardines.
To ensure an adequate intake of omega-3 fatty acids, it is important to consume different foods that contain ALA, DHA, and EPA. Let us look at some of the best omega-3 foods to include in your diet.
10 must-have omega-3 foods
1. Salmon
Salmon is popular for its delicious taste, but it is also one of the richest sources of omega-3 fatty acids, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Due to its composition of these fatty acids, salmon can help reduce blood pressure and decrease the risk of plaque buildup in arteries to support overall cardiovascular health.
Moreover, due to its DHA content, salmon can boost cognitive function and can reduce the risk of age-related mental decline. Salmon is particularly beneficial for pregnant women as it contains omega-3 fatty acids that can support fetal development and brain growth.
2. Edamame
Also called young soybeans, edamame contain significant amounts of the omega-3 fatty acid alpha-linolenic acid (ALA). Consuming edamame can help enhance heart health by aiding the regulation of blood pressure, thereby reducing the risk of heart disease.
The alpha-linolenic acid (ALA) in edamame can also boost cognitive function by aiding brain development and growth. Edamame can also aid in the reduction of inflammation in the body to support optimal health. Consume edamame steamed or boiled, or add them to soups and stir-fries for a boost of omega-3 fatty acids.
3. Chia seeds
Over the years, chia seeds have become popular due to their rich nutritional content. Chia seeds are one of the major sources of alpha-linolenic acid (ALA) which supports heart health and brain function. This omega-3 fatty acid can help regulate cholesterol levels and reduce the risk of diseases such as hypertension and stroke.
Chia seeds can also support brain health. They are rich in other nutrients such as fiber, which can boost digestive health by aiding regular bowel movements. They are also loaded with antioxidants that can help reduce inflammation and protect the body from oxidative stress. Consume chia seeds in baked goods or in yogurt and oatmeal.
4. Shrimp
Shrimp are not only delicious but also nutritious. They are low in calories and contain high amounts of protein, which makes them a good fit for weight management diets. They contain astaxanthin, a potent antioxidant that can help reduce the levels of inflammation in the body. In addition, they are a rich source of eicosapentaenoic acid (EPA) and contain smaller amounts of docosahexaenoic acid (DHA). These fatty acids are beneficial for brain function and heart health and can help maintain overall wellness.
Additionally, shrimp are a good source of different minerals and vitamins like niacin, vitamin B12, selenium, zinc, and phosphorus. It is important to mention that how shrimp are prepared can affect their omega-3 fatty acid content, so opt for healthy cooking options like baking, grilling, and steaming to get the best nutrition out of them.
5. Seaweed
Also known as sea vegetables, seaweed comprises different marine plants that are harvested and consumed for their amazing nutritional advantages. They contain diverse nutrients that include vitamins C, E, A, and K, calcium, iron, and magnesium. Seaweed is particularly noted for its high iodine content, which is highly beneficial for thyroid function.
Some types of seaweed, such as wakame and kelp, contain significant amounts of omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which is beneficial for heart health. The ALA composition in seaweed can help reduce blood pressure and maintain healthy cholesterol levels.
6. Walnuts
Walnuts are loaded with diverse nutrients that offer numerous health benefits. They also contain omega-3 fatty acids, especially alpha-linolenic acid (ALA), which supports heart health by balancing cholesterol levels. Walnuts also contain antioxidants like polyphenols, which can help eliminate free radicals and decrease oxidative damage to cells in the body.
