About Yolk
Egg yolk is the yellow, nutrient-rich portion of an egg, surrounded by the albumin (egg white). Commonly used in cuisines worldwide, yolks are prized for their creamy texture and ability to emulsify in dishes like sauces and dressings. Originating from domesticated chicken eggs, they are a versatile ingredient in baking, cooking, and garnishing. Egg yolks are a dense source of nutrition, including healthy fats, protein, vitamins (notably Vitamin D), minerals like calcium and iron, and cholesterol. While calorically rich at 323 calories per 100 grams, yolks contribute significant nutrients crucial for bone health and cellular function, illustrating their value in a balanced diet.

Are there any health concerns with eating yolks?

However, research suggests that moderate egg consumption is generally not associated with increased heart disease risk in healthy individuals.
How many yolks should I eat in a day?
For most people, eating 1-2 whole eggs, including the yolk, per day is safe and provides valuable nutrients. Those with specific dietary restrictions or health conditions, such as high cholesterol, may need to consult a healthcare provider for personalized advice.
How does yolk compare to egg white in nutrition?
Yolk and egg whites differ significantly in nutrients. While egg whites are lower in calories and contain more protein (about 11 grams per 100 grams compared to yolk's 15.88 grams), yolks provide more fat, vitamins (like A, D, E, and K), and minerals, making them more nutrient-dense overall.
