Can you eat too many egg whites?

It's unlikely to eat too many egg whites, but there are a few things to consider:

1. Protein intake: Egg whites are a great source of protein, but consuming excessive amounts can strain your kidneys. Most healthy adults can handle 0.8 grams of protein per kilogram of body weight per day, but this can vary based on individual needs and health conditions.

2. Nutrient deficiencies: While egg whites are low in fat and calories, they lack some essential nutrients found in the yolk, like vitamins A, D, E, and K, as well as iron and choline. If you're only eating egg whites, it's important to ensure you're getting these nutrients from other sources.

3. Biotin deficiency: Consuming large amounts of raw egg whites can interfere with the absorption of biotin, a B vitamin. However, cooking egg whites eliminates this concern.

4. Individual sensitivities: Some people may be sensitive to egg whites and experience allergic reactions. This is less common than allergies to the yolk, but it's important to be aware of any potential sensitivities.

5. Overall diet: The best way to determine if you're eating too many egg whites is to consider your overall diet. If you're getting enough protein and nutrients from other sources, and you're not experiencing any negative effects, then eating a moderate amount of egg whites is unlikely to be harmful.

In summary:

* It's unlikely to eat "too many" egg whites in terms of toxicity, but excessive protein intake can be a concern.

* Make sure you're getting essential nutrients from other sources, especially if you're only consuming egg whites.

* Be mindful of potential sensitivities and allergic reactions.

* Consider your overall diet to ensure you're maintaining a balanced nutritional intake.

If you have concerns about your protein intake or egg consumption, it's always best to consult with a healthcare professional or registered dietitian.
