Egg Nutrition Facts

1. Calorie Content

One large-sized egg, about 50 grams, contains approximately 72 calories.

2. Complete Protein

Eggs are one of the few foods considered to be a complete protein, meaning they contain all nine essential amino acids our bodies can’t produce on their own.

3. Cholesterol Content

One large egg contains roughly 186 mg of cholesterol, all of which is found in the yolk. This led to the misconception that eggs are bad for heart health, but more recent research shows dietary cholesterol doesn’t impact blood cholesterol as much as once thought.

4. Egg Whites and Yolks

While the egg white is rich in protein, the yolk contains the majority of an egg’s vitamins and minerals, including Vitamins A, D, E, and K.

5. Eye Health

Eggs are rich in two antioxidants, lutein and zeaxanthin, which are essential for eye health. They can help prevent macular degeneration, a leading cause of age-related blindness.

6. Weight Management

Eggs can help with weight management because they’re high in protein, which can make you feel fuller for longer.

7. Eggs and Heart Health

Despite the cholesterol content, eating eggs in moderation does not increase the risk of heart disease for most people. Some studies have even suggested they may help raise “good” HDL cholesterol.

8. Omega-3 Eggs

Eggs from hens fed a diet rich in omega-3 fatty acids can have significantly higher levels of these heart-healthy fats.

9. Vitamins B

Eggs are a good source of B vitamins, including B2 (riboflavin), B12, and B5. These vitamins help with energy production, brain function, and maintaining healthy skin and eyes.

10. Egg Allergies

Egg allergies are common in children, but most outgrow them by adolescence. Always consult a healthcare professional if you suspect an egg allergy.

11. Type 2 Diabetes

Research suggests that eating too many eggs might increase the risk of developing type 2 diabetes. However, more research is needed to understand this association.

12. Vitamin D

Eggs are one of the few natural food sources of Vitamin D, which is essential for bone health.

13. Iron Content

The iron in egg yolk is in the form of heme iron, the most readily absorbable and usable form of iron in food.

14. Hair and Nails

The protein and sulfur in eggs can promote healthy hair and nails.

15. Egg Sizes

The size of an egg affects its nutritional content. Larger eggs have more protein, but also more fat and cholesterol.

16. Egg Color

The color of an eggshell doesn’t indicate the quality or nutritional content of the egg, but rather the breed of the hen.

17. Organic Eggs

Organic eggs come from hens that are fed organic feed and have access to the outdoors. They can have higher levels of omega-3 fatty acids and Vitamin E.

Daily Consumption of Eggs

The question of how many eggs to eat per day is a hotly debated topic. Here’s what the current research says:

1. One Egg a Day

For most people, eating one egg per day is considered healthy. It can contribute to a balanced diet without significantly raising the risk of heart disease.

2. Two Eggs a Day

A study found that eating up to two eggs per day has no impact on heart health in individuals with prediabetes or type 2 diabetes.

3. Three Eggs a Day

Some health experts suggest that eating three eggs a day can provide numerous health benefits, including higher levels of good cholesterol.

4. Four Eggs a Day

While there’s no fixed limit, eating four eggs a day may be too much for some individuals, especially if they have diabetes or a high risk of heart disease.

5. Twenty Eggs a Day

Eating 20 eggs a day is not recommended for most people due to the high dietary cholesterol intake. However, individuals with certain dietary requirements or professional athletes may have different needs.

Best Ways to Cook Eggs

How you cook eggs can affect their nutritional content and health benefits. Let’s look at some popular cooking methods:

1. Boiled Eggs

Boiled eggs are one of the healthiest ways to eat eggs because they don’t require any additional fat.

2. Scrambled Eggs

Scrambled eggs are healthy, but adding milk or cream increases the calorie and fat content. For a healthier option, scramble your eggs in olive oil or cook them without any added fats. Scrambled egg on whole-grain toast can be a balanced meal, providing protein, fiber, and essential vitamins and minerals.

3. Sunny Side Up Eggs

Sunny side up eggs can be a healthy option when cooked without excessive added fats. They retain most of the egg’s nutrients and don’t require additional fat for cooking.

4. Omelets

To make your omelet healthier, try using olive oil instead of butter and fill it with plenty of colorful vegetables.

5. Scrambled Eggs vs. Boiled Eggs

While both scrambled and boiled eggs are healthy, boiled eggs have fewer calories and fat because they’re cooked without additional ingredients.

6. Omelets vs. Boiled Eggs

Omelets and boiled eggs both have their benefits. While omelets can contain additional nutrients from added vegetables, boiled eggs have fewer calories and fat if no oil or butter is used.

7. Raw Eggs vs. Cooked Eggs

Raw eggs have all the same nutrients as cooked eggs, but they also have a risk of salmonella infection. Cooking eggs also makes the protein more digestible.

8. Bodybuilders and Eggs

Bodybuilders often eat scrambled eggs because they’re a quick and easy source of protein. Some also consume raw eggs, although this is less common due to the risk of salmonella.


Eggs are undeniably an amazing and versatile food that can be used in so many delicious recipes. They are chock-full of nourishing and health-promoting vitamins, minerals, proteins, fats, and antioxidants essential for a healthy diet. With rare exceptions, most people should not worry too much about consuming eggs on a daily basis – they’re generally safe to eat unless you have an allergy or intolerance. In fact, eggs may offer protection against heart disease and other possible ailments.
