Nutritive Value of Eggs (What's in it?)
infoNote
Nutritive Value: Focuses on the nutrients eggs provide (e.g., protein, vitamins).
- High-Quality Protein: Eggs are a great source of HBV (High Biological Value) protein, which is important for growth and repair.
- Fats:
- The yolk contains both saturated and unsaturated fats, which provide energy.
- The white contains no fat.
- Vitamins: Eggs provide vitamins A, B group, D, E, and K but lack vitamin C.
- Minerals: Eggs are a good source of calcium, iron, and phosphorus, supporting bone health and red blood cells.
- High Water Content: Eggs are mostly water, especially in the egg whites, which helps with hydration.
Dietetic Value of Eggs (Why They're Good for You)
infoNote
Dietetic Value: Focuses on how eggs fit into specific diets (e.g., vegetarian, high cholesterol).
- Great for All Ages: Eggs are high in easily digestible protein, making them ideal for children, teenagers, pregnant women, and vegetarians.
- Low-Calorie Option:
- Egg whites contain no fat, so they're perfect for low-calorie diets.
- To keep calories low, try poaching or boiling instead of frying.
- Balanced Meal: Eggs are best eaten with foods that have carbohydrates and vitamin C (e.g., toast and orange juice) to create a balanced meal.
- Nutrient-Dense: Eggs are packed with nutrients and are low in calories, making them ideal for low-calorie diets.
- Affordable and Quick to Cook: Eggs are economical and cook quickly, using minimal fuel, so they're a good option for people on a low income.
- Eggs and Cholesterol: In the past, people were advised to limit egg consumption due to cholesterol concerns. However, modern research shows that eggs contain omega-3, which actually helps lower cholesterol, making them safe to eat more frequently.
