How should I track Lobster, tail only, frozen, wild caught?
Lobster, tail only, frozen, wild caught is a good source of zinc. For the most accurate tracking of Lobster, tail only, frozen, wild caught, 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.
