Eggs are an indispensable ingredient in our daily life, rich in nutrition and inexpensive, and can be made into steamed eggs, scrambled eggs, boiled eggs, fried eggs, etc., in a variety of ways. Eating an egg in the morning can meet the body's nutritional needs for the day, which can be easily absorbed and digested by the body.
Eggs have a great effect on the development of the nervous system and body, and at the same time can protect the liver and delay aging. You may not be stocking up on meat at home, but you will definitely stock up on some eggs.
At present, the eggs sold in the market are mainly red shell eggs and white shell eggs. Many people are confused: should they buy white-shell eggs or red-shell eggs? What is the difference between these two types of eggs? Which egg is more nutritious?
First of all, we need to understand why there are different colors of eggs. In general, eggs with red shells will mostly be placed in a frame, while eggs with white shells will be neatly arranged in a row. In addition, white-shell eggs are usually better-looking, and some merchants will also print fonts on the eggs, and the price will be slightly more expensive. However, this difference does not mean that red shell eggs are less nutritious.
In fact, the color of eggs is mainly influenced by genetic factors. Depending on the reproductive system and breed of hen, the color of the eggs will also vary. That is, the color of the eggshell is determined by the type of hen, and some hens secrete pigments that change color during the formation of the eggshell.
So, which is more nutritious, red shell eggs or white shell eggs? Eggs can be divided into native eggs and feed eggs. Native eggs refer to coarse grains such as corn, sweet potatoes, wheat, and rice that are laid by free-range chickens. Whereas, fodder eggs refer to the eggs laid by chickens that are fed with specialized feed. Generally speaking, white-shell eggs are mostly native eggs, while red-shell eggs are mostly feed eggs.
The price of white-shell eggs in the market is generally higher because it is believed that the nutritional value of native eggs is higher than that of feed eggs. However, it is important to be clear that eggshell color is not a criterion for judging the nutritional value of eggs.
The nutritional value of eggs depends on the health of the hen. Whether it is a red-shell egg or a white-shell egg, its nutrients include protein, cholesterol, fat, and other trace elements.
While there may be differences in the nutritional content of different varieties of eggs, this difference can be said to be minimal. For example, in terms of protein content, white-shell eggs are only 0.75% higher than red-shell eggs. Therefore, the nutritional value of eggs is basically the same.
When buying eggs, how should we choose? The most important thing is to make sure that the eggs you buy are fresh and safe, and it is recommended to go to a large market or supermarket to buy them. When picking eggs, do not buy eggs with cracks on the surface, as these eggs are likely to have collided during transportation, and cracks can cause bacteria to enter the inside of the eggs, accelerating spoilage.
Fresh eggs have no sound when they shake, and the shell fits tightly with the egg whites. If you hear a crashing sound when shaking, then it is possible that the egg has gone bad. Observe the eggs under the light, and if you notice bubbles, the eggs are not fresh.
In addition, the shell of fresh eggs is usually coarser with burr edges. If the shell is too smooth, it may have been treated or stored for too long. If there are blood stains or obvious dirt on the eggs, it also means that the growing environment is poor and the nutritional value is low.
Choosing eggs based on use is also a trick. If you want to make a beaten egg drop soup, it is advisable to choose white shell eggs because of their high protein content. Fried eggs and wrapped eggs are suitable for red shell eggs because the yolk will be larger and yellower, and the dish will be more beautiful.
I believe that everyone has a clearer understanding of red shell eggs and white shell eggs. At the same time, I also mastered some tips for buying eggs. Don't waste any more unjust money!
