Egg
What it is
This entry covers a whole egg, including the white and yolk. Its nutrition example is hard-boiled whole egg. Egg whites alone, dried egg products, and eggs prepared with other ingredients have different profiles.
What it does
The reference food supplies 12.6 g of protein, 294 mg of choline, and 1.11 micrograms of vitamin B12 per 100 g. It also supplies fat and dietary cholesterol. Looking at the whole profile is more informative than treating the food as a source of only one nutrient.
Research context and ingredient forms
A composition table does not determine how egg intake affects an individual's blood cholesterol or establish a recommended number of eggs. Those questions require evidence beyond the nutrient content listed here. This entry makes no therapeutic or individualized intake claim.
Using this information
The table is per 100 g of edible cooked egg, not per egg. If you weigh a peeled portion, its nutrient estimate is the table value multiplied by the portion's grams divided by 100. Added butter, oil, or sauces require separate accounting.
Considerations
Egg is a major food allergen. People with an egg allergy should check ingredient labels and avoid egg as advised for their allergy.
