Egg Yolk Nutrition Overview
The egg yolk is the yellow portion of an egg, containing the majority of the egg's fat, cholesterol, and fat-soluble vitamins. One large egg yolk weighs approximately 17 grams and provides a concentrated source of nutrients.
Unlike egg whites, which are primarily protein and water, yolks contain a diverse nutrient profile including healthy fats, choline, and vitamins A, D, E, and K.
Calories and Protein in Egg Yolk
Calculation Formula
Example: 2 yolks = (2 × 17) ÷ 100 × 322 = 109.5 kcal
Per Large Egg Yolk (17g) — USDA Data
While egg yolks contain less protein per gram than egg whites (15.9g vs 10.9g per 100g), the yolk provides approximately 40% of the total protein in a whole egg. The protein in egg yolks has excellent bioavailability.
Fat Content in Egg Yolk
Egg yolks are notably high in fat, with approximately 26.5g of fat per 100g. Here's how the fat breaks down:
| Fat Type | Per 100g | Per Yolk (17g) |
|---|---|---|
| Saturated Fat | 9.55g | 1.6g |
| Monounsaturated Fat | 10.2g | 1.7g |
| Polyunsaturated Fat | 4.2g | 0.7g |
The fat in egg yolks includes a higher proportion of monounsaturated fat (the same type found in olive oil) compared to saturated fat. This composition is often referenced in nutrition research.
How Cooking Methods Affect Egg Yolk Nutrition
The base nutritional content of egg yolks remains relatively stable across cooking methods. However, the addition of cooking fats can significantly increase the total calorie and fat content:
| Method | Added Fat | Notes |
|---|---|---|
| Boiled | None | Base nutrition preserved |
| Poached | None | Cooked in water only |
| Fried | +30-50 kcal | Depends on oil/butter amount |
| Scrambled | +20-40 kcal | Often includes butter or cream |
