Masago is the edible roe (fish eggs) of the capelin fish, a small species found in cold waters such as the Arctic and North Atlantic. This tiny, orange-hued ingredient is commonly used in Asian cuisine, particularly as a topping for sushi rolls. While it is often mistaken for tobiko (flying fish roe), masago is smaller, less crunchy, and more affordable, making it a popular substitute.

It is also rich in omega-3 fatty acids, vitamin B12, selenium, magnesium, iron, riboflavin, folate, and phosphorus, making it a valuable addition to a balanced diet.
Masago contains omega-3 fatty acids, which help reduce inflammation, lower blood pressure, and decrease the risk of cardiovascular diseases. Regular consumption of omega-3s is associated with improved heart health and a lower likelihood of heart attacks and strokes.
Omega-3 fatty acids are essential for maintaining healthy vision. They play a key role in the development and function of the retina, helping to prevent conditions such as age-related macular degeneration and dry eye syndrome.
Masago is a good source of vitamin D, which supports calcium absorption and bone mineralization. Adequate vitamin D intake is essential for reducing the risk of osteoporosis and fractures, especially in older adults.
The anti-inflammatory properties of omega-3 fatty acids may help reduce joint pain and stiffness in people with arthritis. Studies suggest that incorporating omega-3-rich foods like masago into your diet can alleviate symptoms of rheumatoid arthritis and other inflammatory conditions.
Masago is low in calories and high in protein, making it a great food choice for weight management. High-protein diets help promote satiety, reduce cravings, and boost metabolism, which can contribute to healthy weight loss.
Protein is crucial for muscle maintenance and growth. Masago provides essential amino acids that help repair tissues, making it beneficial for individuals who engage in strength training or other physical activities.
While masago has many benefits, there are a few potential drawbacks to consider:
High Sodium Content: One tablespoon of masago contains approximately 240 mg of sodium, which can contribute to high blood pressure if consumed in excess.
Processed Additives: Masago is often processed with food dyes, monosodium glutamate (MSG), and sweeteners. Some individuals may be sensitive to these additives.
Allergy Risk: Those with seafood allergies should avoid masago, as it can trigger allergic reactions, including rashes, digestive issues, and respiratory symptoms.
Masago is harvested from female capelin before they have the chance to reproduce, which may contribute to population decline. While Icelandic and Canadian capelin fisheries are considered relatively sustainable, sourcing masago from Russia and Norway may pose environmental concerns. If sustainability is important to you, consider asking your supplier about the origin of the masago you purchase.
Masago is a versatile ingredient that can be enjoyed in various ways:
Sprinkled over sushi rolls or poke bowls.
Mixed into sauces and dressings for a briny, umami flavor.
Used as a topping for rice dishes or seafood.
Incorporated into Japanese-style pasta recipes.
Masago is a flavorful and nutritious seafood option that provides essential vitamins, minerals, and omega-3 fatty acids.
