Many people have a hobby of choosing eggs by color.
Some people believe that eggs have a healthier or more natural brown shell , while others feel the egg has a cleaner white shell and simply tastes better.
But is there any difference between brown shell eggs and white shell eggs rather than internal quality?
This article will explore whether an egg is actually healthier and tastier.
Eggs are colorful
Chicken eggs can be of different colors and eggs with brown or white shells are often sold in supermarkets.
However , Many people do not know what causes the color difference of eggs.
The answer is quite simple - the color of the egg depends on the breed. Eg White lay eggs are white , when (chicken owl) and egg laying brown ( , ).
Some breeds like Araucana , Ameraana , Dongxiang and Lushi , even lay eggs blue or blue .
The different colors of the eggshell are due to the different pigments that the hens produce. The main pigment in brown eggshell is called . It is formed from red pigment , a compound that makes blood red .
The main pigment found in blue eggshell is called , Also derived from red pigment. It is also a color pigment for bile and gastrointestinal waste in yellow ( , ).
But while genetics is the factor that determines the color of eggs, other factors can also have an effect .
For example , like brown hen hens, they tend to spawn larger and brighter colors. Environment , The diet and stress level of the chickens can also affect the color of the eggshell to some extent .
These factors may make the eggshell darker or brighter , not necessarily change its color. The main factor determining color is still the chicken breed.
Summary: Chicken eggs may be brown , white or even blue. The color of the egg is determined by the breed.
Is the brown-skinned chicken egg healthier than the white-shelled chicken egg?
Usually, common, normal , Those who like brown egg eggs do so because they believe brown eggs are more natural and healthier than white eggs.
However , The truth is that all eggs are equally nutritious , regardless of color , size or type ( , , ).
Both eggs have brown and white shells healthy food . An ordinary egg contains lots of vitamins , High quality minerals and proteins , all without up to 80 calories .
However , The scientists compared golden-shelled eggs with white-shelled eggs to see if there were any differences. Some studies show that the color of the shell does not significantly affect the quality and composition of eggs .
This means that the color of the eggshell is not related to how healthy it is. The only difference is the pigment of the shell.
However , There are many other factors may affect the nutrient content of eggs.
Habitat of hens can have a great influence. For example , The eggs of the hens are allowed to travel under the sun contained 3-4 times Vitamin D intake You find in an egg of an industrially raised chicken .
The type of food that hens eat can also affect the content of nutrients in eggs.
Hens are fed according to the rich regime omega-3 fatty acids creating eggs that have more omega-3 fatty acids than usual. The same effect occurs with vitamin D when chickens eat foods rich in vitamin D ( , ).
Summary: There are no nutritional differences between brown and white shell eggs. However , The diet and habitat of hens can affect the nutrition in eggs.
Does the egg have a better color?
Some argue that brown shell eggs taste better while others like the taste of white-shelled eggs.
But as well as with nutrient content , There is no real difference between the taste of the white egg and the brown shell .
However , that doesn't necessarily mean that all All kinds of eggs have the same taste.
Although the color of the shell does not make a difference, other factors such as food type , Freshness and how to cook eggs can affect the taste.
For example , The chicken is fed a fat-rich diet for eggs with a better flavor than low-fat chicken. And the chickens fed the food are plenty fish oil , a certain type of fat or even vitamin A or D can produce chicken eggs that smell fish or have strange taste ( , , ).
The diet of domestic chickens is not the same as that of industrially raised chickens , Can also affect the flavor of chicken eggs.
More , The longer the egg is stored, the more likely it is to lose its taste. Store eggs at low and stable temperatures , like in the refrigerator , Can help preserve flavor longer ( .
These reasons can explain why some people believe that farmed chicken eggs taste better than industrial chicken eggs.
Chicken eggs are raised in the backyard without processing or moving like industrial chicken eggs , so they can be more comfortable on your plate than eggs bought from shops. Because they are fresher, they may taste better.
The surprising thing is how egg is cooked Can also affect its taste.
A study looks deeply at the problem of fish oil , How is it used to make chicken food to increase the amount of omega 3, changing the flavor of eggs. It is thought that industrial fish and eggs have the same taste when making scrambled eggs .
However , when boiled , eggs of chickens that eat fish oil are more exotic or taste like sulfur .
Therefore , While many factors can affect egg taste , But the shell color is not.
Summary: White and brown shell eggs often have the same taste. But eggs can taste different depending on the freshness , how they are processed and the diet of chickens.
Why does the egg with the brown shell have a higher price?
Although white and brown shell eggs seem to be the same in every color outside , Brown shell eggs still tend to be more expensive when sold.
This fact makes many people believe that brown egg shells are healthier and better quality than white shell eggs.
However , The reason for the price gap is quite different.
Reality , Brown shell eggs are more expensive than before , Brown egg-laying chickens tend to be larger and lay fewer eggs than white-layered chickens. Therefore , Brown shell eggs are sold at a higher price to compensate for the costs incurred .
Nowadays , Brown egg-laying chickens have the same production cost as white-shelled chickens. However , Their eggs still tend to be sold at a higher price
This may be due to the speciality of eggs such as grazing or natural , tends to be more brown than white.
Summary: Brown-shelled eggs are usually more expensive because brown-hens lay less and heavier. While this is no longer true, brown shell eggs are still sold at a higher price.
If color is not a problem, what is the problem?
Obviously color is not an important factor. So what do you consider when buying eggs?
This is a way of looking at the types of availability and the meaning of labels.
All are natural
The term "natural" is not managed in the United States because nature cannot be determined .
Eggs labeled "naturally raised" or all natural "are no different from other eggs.
Naturally certified eggs in the United States and the European Union are from chickens fed only natural and non-GM foods.
They are also grazed outdoors all year round.
More , they have not used antibiotics or hormones , although hormones are never allowed for laying eggs .
Natural labels mean that antibiotics can only be used when medically necessary. If not , Low doses of antibiotics are usually given in food and drinking water can contribute to antibiotic resistance in bacteria.
The current , There is no evidence that organic eggs are more nutritious than industrial eggs .
However , The quality of life of naturally certified chickens may be better and be more exposed to sunlight , may increase the amount of vitamin D in eggs .
Breeding no barn
When the term "non-barn farming" is applied to eggs, it can be misunderstood.
While US farmed chickens are kept indoors in very small and separate cages, farmed chickens are kept indoors or open rooms .
However , living conditions of non-barn chickens are often more crowded , and they must not be exposed to outdoor conditions.
Non-barn farming can be slightly better for hens. However , In terms of nutrition, eggs of non-barn-fed chickens may not be more beneficial than industrial chicken eggs.
Drop the garden
"Garden" label means that the eggs of domestic hens are kept in the form of outdoor contact .
This provides an ideal life with better quality for chickens.
It can also increase the quality of the nutrients of eggs , Because the chickens are exposed to the sun producing eggs with higher levels of vitamin D .
Enriched with omega 3
Rich in omega-3 eggs comes from chickens fed a diet rich in beneficial omega-3 fats. Therefore , Omega-3 content of eggs is higher than normal.
Enriched eggs omega-3 provide an alternative source of omega-3 fats that are often very limited in human diets. Choosing omega-3 rich eggs can be beneficial for health.
Before , A small study showed that consuming 4 omega-3-rich eggs daily for 4 weeks reduced blood triglyceride levels and blood pressure in participants .
Another study found that consuming two omega-3-rich eggs every day for six weeks increased the content of omega-3 fats in breastmilk of lactating mothers .
General , Omega-3 rich eggs may yield some health benefits over normal eggs.
Farming eggs in the yard and local eggs
Eggs from livestock herds or bought directly from small local farms can be the freshest eggs and often come from chickens that live in a natural environment with lots of sunlight.
The diets of farmed chickens may be different from those of industrial poultry and this may also affect the nutrient content of eggs.
This is especially true if the hens are exposed to the grass because the grass is fed as well as the industrial feed is thought to produce eggs with higher levels of omega-3 fats and vitamin E .
However , Livestock farming does not have to comply with food hygiene and safety regulations such as industrial livestock , so you should buy local eggs or a garden only from sources you know to follow good care and hygiene procedures.
Summary: The color of the egg does not matter , But there are many other factors to consider when choosing eggs.
Eggs are colorful , depending on the breed.
However , There are no nutritional differences between brown shell eggs and white shell eggs. Finally, the only difference is the shell color and may be the price.
However , Other factors still affect the flavor and nutrition of eggs , including chicken diet and culture conditions.
So the next time you buy an egg carton, make sure you look through these other factors. The color of the eggshell doesn't say it all.
