What the nutrition record actually describes
The reference is USDA FoodData Central food 174202, from the April 2018 SR Legacy release. Its basis is per 100 g edible portion. Food names in search results can hide important differences: the record description, rather than the broad headline alone, determines whether this panel matches your serving.
The figures below are scaled from that source record. Missing nutrients are labeled “Not reported”; an absent sugar value is not evidence that a food contains no sugar. Values may be rounded, and a current product label takes precedence for that exact packaged product.
Weigh the edible crab meat
Crab shells are not included in the edible-weight reference. A whole crab or a cluster on the scale is heavier than the meat that ends up in your meal, so logging shell-on weight as edible meat overstates the portion.
Species and preparation matter: Dungeness, queen and Alaska king crab have separate database entries. Butter, dipping sauce and seasoned cooking liquid are not automatically part of plain cooked meat.
Calculated portion examples; not serving recommendations
| Edible portion | Energy | Protein | Carbohydrate | Fat |
|---|---|---|---|---|
| 25 g | 24.3 kcal | 4.9 g | 0 g | 0.4 g |
| 50 g | 48.5 kcal | 9.7 g | 0 g | 0.8 g |
| 75 g | 72.8 kcal | 14.6 g | 0 g | 1.2 g |
| 100 g | 97 kcal | 19.4 g | 0 g | 1.5 g |
| 150 g | 145.5 kcal | 29.1 g | 0 g | 2.3 g |
How to calculate the portion on your plate
Multiply the per-100-g value by your edible portion in grams and divide by 100. A 75 g portion of this reference has approximately 72.8 kcal; a 150 g portion has approximately 145.5 kcal. Those are mathematical examples, not recommended serving sizes.
Use the same scaling for protein, carbohydrate and fat. For a mixed recipe, calculate each ingredient first, add the batch, then allocate the share eaten. If a finished batch weighs 600 g and you serve 150 g, you have one quarter of the batch nutrition; the recipe's water content affects its final weight.
Where the reference is useful—and where it stops
Use this panel to compare like-for-like portions and to understand what drives the meal total. It does not decide whether alaska king crab (cooked) is suitable for a particular medical diet, nor does one nutrient describe the quality of an entire day.
A meal can include additional vegetables, grains, proteins, sauces and drinks. Record the components you ate rather than judging the plate from a single ingredient. If you need a sodium or other nutrient limit for a condition, use the plan agreed with your healthcare professional.
Logging alaska king crab (cooked) with BiteCal
Photograph the meal in good light with the whole serving visible. Review the foods the scanner suggests, match the preparation, and adjust the portion before saving. Photo recognition is a starting estimate; it cannot read the weight under a pile of food or identify every hidden recipe ingredient.
Compare the saved calorie and macro totals with the reference and your portion calculation. Review the daily diary rather than assuming one scan is exact. A label or measured homemade recipe is often a better source when the product or recipe is known.
Frequently asked questions
How many calories are in 100 g of alaska king crab (cooked)?
97 kcal in this specific USDA reference. Match the food description and preparation before applying that number to a meal.
Can I use the same number for a different brand?
Use the current product label if you have one. The historical USDA entry describes crustaceans, crab, alaska king, cooked, moist heat, so a different formulation or preparation may differ.
Why does my food diary show another value?
Check whether the entries use the same grams, preparation state, edible portion and source. A cooked item, dry ingredient and complete recipe can have different values even when their names look similar.
