Is Bottarga Healthy?

Bottarga, dried and salt-cured roe from grey mullet or tuna, is a genuinely nutrient-dense food in small amounts: it's a strong source of protein (40.0g per 100g) and a real concentrated source of omega-3, about 4,000mg per 100g, split between EPA and DHA. The real catch is the salt from how it's preserved, 5.8g per 100g, so even a single tablespoon (15g) carries close to 0.9g of salt, worth keeping in mind if you eat it often. Carbohydrate-free and fat comes mostly from the fish itself. Fish roe like this is naturally halal and kosher, since both grey mullet and tuna are permitted fish for either, and it's flagged for fish as its allergen.
