Some people think that orange egg yolks are more nutritious and healthier than yellow egg yolks. However, experts say that egg selection should be based on more criteria such as breeding quality rather than color.
What factors affect the color of egg yolk?
Dr. Nguyen Thu Ha - Head of the Nutrition and Dietetics Department - Nam Sai Gon International General Hospital said that egg yolks can vary from light yellow to deep orange and the color of the yolk does not reflect the nutritional value or quality of the egg. The color of the egg yolk is largely the result of a diet high in carotenoids (organic pigments) found in animal feed. Feed is the biggest factor affecting the color of the yolk.
The color of the yolk does not reflect the nutritional value or quality of the egg.
Yellow egg yolk : When the hen's food is usually colorless, low in carotenoids (natural pigments that create the red-yellow color of plants) such as rice, cassava, potatoes, white corn flour (corn) or industrial animal feed.
Orange egg yolks : When chickens are fed foods rich in carotenoids such as yellow corn, pumpkin, carrots, kale, bell peppers, sweet potatoes, etc. However, some types of industrial animal feed can also darken the color of egg yolks. In addition, dark egg yolks are often found in free-range eggs, especially in the summer months.
Which color egg yolk is better?
Doctor Thu Ha said that chicken eggs are a rich source of nutrients necessary for the body. 100g of chicken eggs provide 150 kcal, 12.9g of protein, 10.3g of fat and essential minerals such as calcium, iron, iodine, zinc, phosphorus; important vitamins for the body such as vitamins A, B, D, E and K. With abundant nutritional value, chicken eggs bring many health benefits, good for the heart, brain, eyes...
Chicken eggs provide many nutrients that are good for health.
However, according to Dr. Ha, the nutritional value of orange or yellow egg yolks is not much different. Therefore, instead of worrying about the color of the yolk, we should choose eggs from healthy chickens that are raised naturally and fed natural foods. Limit the use of eggs from chickens that are fed foods that are not nutritious enough.
"In addition, you should choose to buy eggs with clear origin, quality certification, production time and expiry date to ensure health safety," Dr. Ha recommends.
Notes when using chicken eggs
Doctor Ha said, some notes to help use chicken eggs are as follows:
- Adults can eat 3 - 4 eggs/week.
- People with high cholesterol should only eat 1-2 eggs/week, or only use egg whites (contains lecithin fat to help reduce bad cholesterol and increase good cholesterol).
- Children can eat 1 egg/day.
- Elderly people can eat 1-2 eggs/day, however, they should adjust the amount of eggs used to suit their health condition.
"Combining the use of eggs in the right amount with a diverse, healthy diet helps you maximize the nutritional value of eggs, limiting risks related to cholesterol and other health problems," the doctor shared.
