Learn the evidence-based health benefits of seafood and what makes them a staple worth incorporating into your diet.

Is Seafood Healthy?

Seafood is generally considered a healthy food choice. It is a rich source of high-quality protein, essential vitamins, and minerals.

Moreover, seafood, especially fatty fish like salmon and mackerel, is renowned for its high omega-3 fatty acids associated with numerous cardiovascular and overall health benefits.

However, it's essential to make sustainable and safe seafood choices, be mindful of potential contaminants like mercury, and maintain a balanced diet to enjoy the health advantages of seafood consumption.

6 Health Benefits of Eating Seafood

Eating seafood offers various health benefits due to its nutritional composition. Here are the top 6 benefits of consuming seafood:

1. Rich Source of Omega-3 Fatty Acids

Seafood, especially fatty fish like salmon, mackerel, and trout, is one of the best natural sources of omega-3 fatty acids. These essential fats promote heart health by reducing the risk of heart disease, improving cholesterol levels, and lowering blood pressure [*].

2. High-Quality Protein

Seafood is a high-quality protein source, providing all essential amino acids in adequate amounts. Protein is essential for muscle growth, repair, and overall body function [*].

3. Cardiovascular Health

Seafood is known for its significant cardiovascular health benefits, primarily due to its high content of omega-3 fatty acids, which have been linked to various heart-protective effects [*].

4. Brain Health

Omega-3 fatty acids found in seafood, particularly DHA (docosahexaenoic acid), are crucial for brain health and cognitive function. Regular seafood consumption may help improve memory, reduce the risk of cognitive decline, and support overall brain development [*].

5. Joint and Bone Health

Seafood is a source of nutrients like vitamin D and calcium, essential for maintaining strong bones and preventing osteoporosis. Additionally, omega-3s in seafood can help reduce inflammation and alleviate symptoms of arthritis [*].

6. Weight Management

Seafood is generally low in calories and fat, making it an excellent choice for those looking to manage their weight. Its high protein content can also promote feelings of fullness and reduce overall calorie intake [*].


Seafood is highly nutritious and is chock-full of healthy fats, proteins, vitamins, and minerals. It is proven to lower the risk of cardiovascular disease, depression, and certain cancers. However, it’s equally essential to source sustainably farmed seafood to ensure they’re free of contaminants.
