Dense salty foods are mis-estimated. 50–200% by eye (Almiron-Roig et al., Appetite 2013). Per 100 g roe: 143 kcal, 22.3 g protein, 91 mg sodium. Use a scale — a teaspoon of roe is 10–15 g, not what your eye calls a teaspoon.
How should I track Roe, mixed species, raw?
Roe, mixed species, raw is high in vitamin d. For the most accurate tracking of Roe, mixed species, raw, weigh it raw and boneless. Fish loses 15–25% of its weight during cooking as water evaporates (USDA cooking yield data). If you are using canned fish, the drained weight is what matters — the difference between oil-packed and water-packed can be 40–80 calories per can. A quick drain-and-weigh habit saves you from hidden calories. Also keep in mind that smoked or cured fish has different values than fresh due to moisture loss and added salt.
