A Detailed Look at Sodium in Eggs
An egg is a surprisingly complex and nutrient-dense food. While generally considered a low-sodium item, the exact sodium count can vary. It's crucial to understand where the sodium in an egg comes from and how different parts and preparation methods can change its value. The World Health Organization recommends adults consume less than 2,000 mg of sodium per day, and a single large egg can make up a small, manageable part of that total.
The Breakdown: Egg White vs. Egg Yolk
Not all parts of an egg are created equal when it comes to sodium. The majority of the sodium is found in the egg white, not the yolk, a fact that surprises many people. For a single large egg:
- Egg White: Contains around 55 milligrams of sodium.
- Egg Yolk: Contains a much smaller amount, approximately 8 milligrams of sodium.
This means that eating just the egg white contributes more than six times the amount of sodium than eating just the yolk. This is a vital piece of information for those tracking their sodium intake, such as individuals with high blood pressure, who might opt for egg whites to reduce their overall daily consumption.
How Cooking Methods Impact Sodium Content
While a raw egg has a fixed amount of sodium, the way it's prepared and cooked can significantly alter its nutritional profile. Most of this change comes not from the cooking process itself, but from what is added during preparation.
Hard-Boiled vs. Scrambled
A hard-boiled egg offers one of the most accurate representations of an egg's natural sodium content, assuming it was boiled without added salt. A single large hard-boiled egg has about 62 milligrams of sodium. This is slightly lower than the average value for a large egg because nutrients can leach into the water during cooking, though the change is minimal.
On the other hand, scrambled eggs often contain a much higher sodium count. For example, a serving of two large scrambled eggs can have as much as 476 milligrams of sodium, primarily because of added salt, milk, or cheese. This illustrates a key takeaway: the primary driver of high sodium content in egg dishes is external additives, not the egg itself. Poached eggs offer a good low-sodium alternative, with one large poached egg containing around 147 milligrams, depending on preparation.
A Quick-Reference Sodium Comparison
To help visualize the difference, here is a comparison table outlining the approximate sodium content of a large egg based on its component and preparation method.
| Egg Type / Component | Approximate Sodium (mg) |
|---|---|
| Raw Whole Egg | 70-74 |
| Raw Egg White | ~55 |
| Raw Egg Yolk | ~8 |
| Hard-Boiled Egg | 62 |
| Scrambled Eggs (2 large, with salt) | ~476 |
| Poached Egg (1 large) | ~147 |
Making Healthy, Low-Sodium Egg Choices
For those looking to manage their sodium intake, eggs can still be a regular part of a healthy diet. The key is to control what you add to them. Here are some strategies for enjoying eggs with less sodium:
- Season with Alternatives: Skip the table salt and reach for salt-free seasoning blends, herbs like dill or chives, or spices like black pepper, paprika, or chili flakes. Lemon juice or a dash of vinegar can also brighten the flavor without adding sodium.
- Choose Fresh: Opt for fresh eggs over processed egg products. Items like egg substitutes or pre-packaged egg patties often have a much higher sodium count due to additives.
- Rethink Your Add-ins: Be mindful of other ingredients. Cheese, bacon, ham, and even some types of bread can be significant sources of sodium. Use these sparingly or seek out low-sodium alternatives.
- Cook at Home: Preparing your own meals allows you complete control over the ingredients. This is the most effective way to manage and reduce your overall sodium intake from eggs.
Conclusion
In summary, a large egg contains between 60 and 75 milligrams of sodium, with the majority concentrated in the egg white. The sodium content can escalate dramatically, however, when other high-sodium ingredients like salt, cheese, or processed meats are added during cooking. By opting for low-sodium seasonings and focusing on fresh, whole ingredients, eggs can remain a versatile and healthy part of a balanced diet, even for those watching their sodium intake.

A Low-Sodium Egg Strategy
- Prioritize Fresh: Always choose fresh eggs and fresh ingredients over processed or pre-made egg products, which contain higher sodium levels.
- Separate the Parts: If extremely conscious of sodium, use only egg yolks, which contain less than 10 mg of sodium per large egg.
- Season Smartly: Rely on herbs, spices, and other salt-free flavorings instead of table salt to enhance your egg dishes.
- Boil or Poach: Preparing your eggs by hard-boiling or poaching minimizes added ingredients and keeps the sodium content low.
- Limit High-Sodium Pairings: Cut back on pairings like bacon, cheese, and cured meats. Instead, serve eggs with fresh vegetables or a side of low-sodium toast.
