Eggs and Health Unveiling the Surprising Benefits
Eggs are a common food item that is consumed by humans and many other animals.
Here are some reasons why people include eggs in their diet:
Excellent Nutritional Profile:
Eggs are packed with essential nutrients, making them a highly nutritious food choice. They contain high-quality proteins, healthy fats, vitamins (A, D, E, B vitamins), minerals (iron, zinc, phosphorus), and antioxidants. This nutrient density makes eggs a valuable addition to a well-rounded diet.
Protein Source:
Eggs are considered a complete protein source as they provide all the essential amino acids our bodies need. Protein is crucial for building and repairing tissues, supporting muscle health, and maintaining a strong immune system.
Weight Management:
Protein in eggs helps promote satiety, which can reduce appetite and calorie intake, leading to better weight control.
Heart Health:
Eggs contain unsaturated fats, including omega-3 fatty acids, which are beneficial for heart health. However, it's still important to maintain a balanced diet and consider individual health factors.
Eye Health:
Eggs are valuable in antioxidants such as lutein and zeaxanthin, which are favourable for eye health.
Brain Function:
Eggs are a reliable source of choline, a nutrient that plays a vital role in brain development and function. Choline is involved in memory, cognitive function, and the formation of neurotransmitters.
Versatility in Cooking:
Eggs are incredibly versatile in the kitchen, making them a popular ingredient. They can be cooked in many ways (boiled, fried, scrambled), used in baking, added to soups or salads, or included in a wide range of dishes, enhancing flavors, texture, and nutritional value.
Cost-Effective:
Eggs are inexpensive compared to many other protein sources, making them an affordable option for individuals on a budget.
Easy to Prepare:
Eggs are quick and easy to prepare, making them a convenient choice for meals and snacks, especially for those with a busy lifestyle.
Here are some popular foods that can be made with eggs:
Breakfast Dishes:
Scrambled eggs

Benefits of eating eggs:
Nutritional Value:
Eggs are highly beneficial and contain a collection of key nutrients. A large chicken egg (approximately 50 grams) typically provides:
Calories: Around 70-80 calories.
Protein: Approximately 6 grams, including all the essential amino acids.
Fat: Around 5 grams, primarily found in the egg yolk.
Cholesterol: The egg yolk contains about 186 milligrams of cholesterol, but it does not significantly impact blood cholesterol levels for most people.
Vitamins: Eggs are a reliable source of vitamins such as vitamin A, vitamin D, vitamin E, vitamin K, vitamin B6, vitamin B12, and folate.
Minerals: They contain minerals like iron, zinc, phosphorus, and selenium.
Types of Eggs:
There are several types of eggs available, depending on the animal species:
Chicken Eggs:
These are the most commonly consumed eggs and are available in varied sizes (small, medium, large, and extra-large).
Duck Eggs:
Duck eggs are bigger than chicken eggs and have a good flavour. They are commonly used in baking.
Goose Eggs:
Goose eggs are larger than chicken eggs and have a higher yolk-to-white ratio.
Ostrich Eggs:
Ostrich eggs are the larger eggs produced by any living bird. They are around 20 times bigger than chicken eggs.
Egg Production:
Eggs are produced by female animals through a process called oviposition. In the case of chickens, hens lay eggs after reaching sexual maturity, usually around 5-6 months of age. They can continue laying eggs for several years, with peak production occurring in the first 2 years.
Eggs are a handy ingredient used in various cooking preparations, such as:
Cooking:
Eggs can be boiled, fried, scrambled, or baked.
Baking:
They are commonly used in baking cakes, cookies, bread, and pastries, as they contribute to the structure, texture, and moisture of the final product.
Binding Agent:
Eggs act as a binding agent in recipes like meatballs, meatloaf, and patties.
Emulsifier:
The proteins in eggs help to emulsify ingredients, allowing oil and water to mix in recipes like mayonnaise and salad dressings.
Safety and Storage:
To ensure safety, it is important to handle and store eggs properly:
Freshness:
Check the date on the egg carton to ensure freshness. Fresh eggs will be submerged in water, while older eggs will swim.
Storage:
Store eggs in their original carton in the refrigerator, as it helps to maintain freshness and prevent absorption of odours from other foods.
Handling:
Wash your hands before and after handling eggs to avoid the risk of contamination.
Cooking:
It is recommended to cook eggs thoroughly to minimize the risk of foodborne illnesses.
Here are some cons of eggs:
Cholesterol Content:
Although dietary cholesterol doesn't have as significant an impact on blood cholesterol levels for most people as previously believed, individuals with certain health conditions, such as familial hypercholesterolemia, may need to limit their intake.
Food Allergies and Sensitivities:
Some individuals may have allergies or sensitivities to eggs, experiencing symptoms such as hives, digestive issues, or respiratory difficulties.
Salmonella Risk:
It's essential to cook eggs thoroughly to reduce the risk of bacterial infection. Individuals with compromised immune systems, pregnant women, young children, and older adults are particularly vulnerable and should exercise caution when consuming eggs.
Environmental Considerations:
Factory farming practices can contribute to issues such as deforestation, water pollution, and greenhouse gas emissions. Choosing eggs from sustainable and ethically produced sources, such as organic or free-range eggs, can help mitigate these concerns.
Ethical Considerations:
The intensive farming practices associated with egg production, particularly in industrial systems, can involve cramped conditions and the removal of beaks or other practices that may be considered inhumane.
Individual Dietary Restrictions:
Eggs are not suitable for individuals following certain dietary patterns or with specific dietary restrictions.
