Step 1
(i) the nutritive value and (ii) the dietetic value of eggs
Answer
Eggs are considered an excellent source of nutrition. The nutritive value of eggs includes:
- Protein Content: Eggs contain high-quality protein, with all nine essential amino acids, making them ideal for growth and repair. The biological value of egg protein is particularly high (approximately 100).
- Vitamins and Minerals: Eggs are rich in vitamins A, D, E, and B complex, particularly B12 and riboflavin. They also provide essential minerals like iron, phosphorus, and selenium.
- Fats: Eggs contain about 10 grams of fat per egg, mainly unsaturated fats; they include essential fatty acids.
In terms of dietetic value, eggs are versatile in cooking and can be incorporated into various dishes, which enhances their appeal in culinary practices. They are suitable for various dietary needs, including mechanisms to aid in weight management due to their satiating qualities.

- Formation of a Firm Structure: Heat causes the egg whites to become firm, while the yolk thickens and can gel.
