Eggs are an important food to consider in terms of nutrition and health for several reasons. Eggs are a good source of high-quality protein, which is important for building and repairing tissues in the body.
Eggs are also a good source of a range of vitamins and minerals, including vitamins A, D, and B12, as well as iron, zinc, and selenium. In addition, eggs contain antioxidants that may help to protect against oxidative stress and chronic diseases such as cancer and heart disease.
Egg Nutrition Facts
Here are some key egg nutrition found in eggs:
- Protein: One large egg contains about 6 grams of protein, which is important for building and repairing tissues in the body.
- Fat: One large egg contains about 5 grams of fat, which can provide energy and help absorb certain fat-soluble vitamins such as vitamins A, D, E, and K.
- Cholesterol: Egg yolks contain cholesterol, with one large egg containing about 186 milligrams of cholesterol. The effect of eggs on cholesterol levels is complex and may depend on an individual’s diet and lifestyle.
- Vitamins: Eggs are a good source of a range of vitamins, including vitamin A, vitamin D, vitamin E, vitamin B12, and folate.
- Minerals: Eggs are a good source of minerals such as iron, zinc, and selenium.
- Other nutrients: Eggs also contain other nutrients such as choline, which is important for brain function, and lutein and zeaxanthin, which are antioxidants that may help to protect against age-related eye diseases.
- Egg Yolk: The yolk is a rich source of vitamins A, D, E, and K, as well as choline, folate, and iron. It also contains all of the egg’s healthy fats, such as monounsaturated and polyunsaturated fats.
- Egg White: The egg white is a good source of protein and contains vitamins B2 (riboflavin) and B3 (niacin), but lacks many of the nutrients found in the yolk.
- Raw Egg: Raw eggs contain all the nutrients of the whole egg, but consuming raw eggs can carry a risk of foodborne illness, particularly if they are not thoroughly cooked.
- Boiled Egg: Boiled eggs are a convenient and healthy food option, retaining many of the nutrients from the whole egg. They are a good source of protein, vitamins, and minerals, including vitamins A, D, E, B2 (riboflavin), and B12, as well as iron, phosphorus, and selenium.
- Dark orange egg yolks: They are often considered to be healthier than lighter-coloured yolks. This is because the colour of an egg yolk is related to the diet of the chicken that laid it. Chickens that eat a diet rich in pigmented foods, such as yellow and orange pigments, produce yolks with a deeper orange colour. In terms of nutritional value, the darker orange yolks are similar to lighter-coloured yolks. They are a good source of vitamins A, D, E, and K, as well as choline, folate, and iron. The yolk is also where the majority of an egg’s healthy fats are found, such as monounsaturated and polyunsaturated fats.
Health Benefits of Eggs

Eggs have been shown to have a number of potential health benefits, including:
Improving Heart Health
There is some evidence to suggest that consuming eggs may be associated with a lower risk of heart disease. This may be due in part to the nutrients found in eggs, such as high-quality protein, antioxidants, and other nutrients that are important for heart health. One study found that replacing one serving of red meat per day with one serving of eggs was associated with a lower risk of heart disease. Other research has suggested that consuming eggs may be associated with a lower risk of stroke and other cardiovascular events.
Supporting Weight Management
Eggs may support weight management in a few ways. Eggs are relatively low in calories This makes them a convenient and nutritious food choice for those trying to manage their weight. In addition, eggs are a good source of high-quality protein, which can help to keep you feeling full and satisfied after eating. This may help to reduce the urge to snack between meals and may contribute to weight management. Some research has also suggested that higher protein diets may be more effective at promoting weight loss and maintaining weight loss compared to lower protein diets.
Aiding in Muscle Building
Eggs are a good source of high-quality protein, which can help to support muscle building and repair. Protein is an essential nutrient that is necessary for the growth, maintenance, and repair of tissues in the body. It is particularly important for athletes and active individuals, as exercise can cause muscle damage that needs to be repaired in order to maintain muscle mass and strength. Consuming enough protein can help to support muscle building and repair, which can improve athletic performance and promote overall health.
Improving Brain Function
The nutrient choline, which is found in eggs, is important for brain function and may help to improve memory and cognitive performance. Choline is a component of acetylcholine, a neurotransmitter that plays a key role in memory, learning, and other cognitive functions. Adequate intake of choline is important for maintaining healthy brain function, and research suggests that choline deficiency may be linked to a number of cognitive problems.
Protecting Against Age-related Eye Diseases
Eggs contain antioxidants called lutein and zeaxanthin, which may help to protect against age-related eye diseases such as cataracts and macular degeneration. Lutein and zeaxanthin are carotenoids, which are plant pigments that have antioxidant properties. These antioxidants accumulate in the retina of the eye and may help to protect against oxidative stress, which is thought to be a contributing factor to age-related eye diseases. Some studies have suggested that consuming foods rich in lutein and zeaxanthin, such as eggs, may be associated with a lower risk of age-related eye diseases.
Side-Effects of Egg
There are a few risks and considerations to be aware of when it comes to consuming eggs:
Food Poisoning
Bacteria like Salmonella, which can result in food poisoning, can occasionally contaminate eggs. Eggs should be handled and stored carefully, cooked thoroughly, and avoided if possible in order to lower the risk of food poisoning.
Cholesterol
Cholesterol can be found in egg yolks; a big egg has roughly 186 mg of cholesterol in it. A person’s diet and lifestyle may have an impact on the complex relationship between eggs and cholesterol levels. While some research has revealed a more detrimental effect, some studies have suggested that eating eggs in moderation may not have a major impact on cholesterol levels. If you have questions concerning eggs and cholesterol, it’s crucial to consult a medical expert.
Allergies
Egg allergies can affect certain people, with symptoms ranging from minor (such as hives or swelling) to severe (such as anaphylaxis). It’s crucial to see a healthcare provider before eating eggs if you have an egg allergy or a family history of allergies.
Other Considerations
Eggs might not be suitable for you if you practice a vegetarian or vegan diet. When making dietary decisions, it’s crucial to take the environmental and ethical effects of egg production into account.
