What is the difference between the nutritional value of firewood eggs and raised eggs?

Not the same. The nutritional value of native eggs and foreign eggs has some similarities, but also there are great differences, the difference is mainly manifested in the difference in the content of essential amino acids and lecithin, native eggs are significantly higher than foreign eggs Native eggs contain 17 kinds of amino acids measured, the total content is, and the total amino acid content of foreign eggs also has, it can be seen that the total amino acid content of the two is not much different. However, from the 7 essential amino acids in the determination (tryptophan was not measured), the essential amino acids contained in native eggs accounted for the total content of amino acids, while the essential amino acids in foreign eggs only accounted for them, which showed that the proportion of essential amino acids in native eggs was significantly higher than that of foreign eggs.

The lecithin content in native eggs is twice that of foreign eggs. And the lecithin of eggs is concentrated in the yolk.

I found it on the Internet, I hope it will be helpful to you: The laying hens in the chicken farm eat scientifically formulated feed, which is very nutritious, but it is not as rich in "taste" as the feed in nature. It is well known that food affects the taste of animals, just as people who eat meat have different tastes from those who eat vegetarian food, and people who eat beef and mutton have different tastes from those who eat fish.

The same is true for eggs: free-range chickens can eat natural "flavor foods" such as grass, insects, grains and grass seeds, and the flavor substances produced in eggs are naturally richer. Chickens raised on chicken farms eat a mixture of feed all year round, and the natural flavor is monotonous.

Let's talk about the color of the egg yolk. Free-range chickens often eat grass and leaves, and green leaves are rich in carotenoids, which accumulate in the yolk and dye the yolk a beautiful orange-red color. Chickens that eat feed don't have a chance to eat grass, so the yolk only has the light yellow color of riboflavin.

However, the feeding method cannot be judged by the color of the egg yolk alone, because at present, some feed additives such as "plus Lisu" have been developed at home and abroad, and the color of the egg yolk will become very beautiful when they are added to the feed. Of course, such additives are safe and harmless. Nutritional studies have found that there is no significant difference in protein, carbohydrates, calcium, iron, etc., between eggs laid by free-range chickens and fed chickens.

Due to the abundance of vitamins added to chicken feed, eggs produced tend to contain higher levels of B vitamins and vitamin A than eggs produced by free-range chickens. However, there are significant differences in fat content, vitamin E content, and long-chain polyunsaturated fatty acid content, and the eggs produced by free-range chickens are higher than those produced by feed chickens. Therefore, it can be said that their nutritional value has its own merits, and it is difficult to say which is better or worse.

Because the feed eaten by the two types of chickens is different. So the nutritional value of eggs is also different.

Chai eggs, also known as native eggs, are eggs laid by free-range chickens at home, its nutritional value is not as high as people imagine in the tomato, the reason is that the real sense of the native chicken should be completely free-range, every day in the woodland activities foraging, only eat insects, weeds and other natural food. Because of the unbalanced nutrition, the eggs laid by this kind of chicken are relatively small, but because the local chickens eat more green leafy vegetables, the content of carotenoids and vitamin B2 in the egg yolk is high, so the egg yolk is larger and darker in color.

What we call ordinary eggs are eggs laid by caged chickens, that is, the cheaper ordinary eggs sold on the market, and they only eat feed. This scientifically formulated feed can also contain a variety of foods and nutrients, so the nutrition of this egg is no worse than the previous two, but it is the cheapest.

Native chickens lay very few eggs and have a long nutrient accumulation cycle, so the fat content of the eggs is high, which is not suitable for the elderly to eat for a long time. But chai eggs also have advantages, which contain higher omega-3 unsaturated fatty acids and phospholipids, which can promote cholesterol metabolism and are very good for cardiovascular protection.

Although chai eggs are not better than Luchayang eggs in terms of nutrition, they have a better taste. Because of the higher fat content in chai eggs, the yolk is larger, making it ideal for boiled eggs and omelettes, and simple cooking methods can bring out its excellent taste. Ordinary eggs have more egg whites, which are suitable for steaming eggs or beating eggs.

The nutritional value of chai eggs and ordinary eggs is usually a little different.

Although firewood eggs and ordinary eggs are more common in life, the nutrients in them may be different due to the different feeding methods of chickens. Both chai eggs and ordinary eggs are rich in protein and the only difference between biosin is the amount of trace elements, which may be different.

Moreover, firewood eggs are eggs laid by free-range chickens in life, which is the so-called native eggs in life, which contain more immune factors. Because of these free-range opportunities, the nutrients such as eating some green vegetables or live insects are higher than ordinary eggs.

Chai eggs and ordinary eggs are also different in appearance, the appearance of the general Chai eggs is a little red, and the color of ordinary eggs is whitish, there are certain differences in nutritional value, although it contains more nutrients, but the fat content and iron content of Chai eggs are higher than ordinary eggs, eat some Chai eggs in moderation in life, absorb more nutrients, taste more than ordinary eggs, no fishy taste of eggs.

Precautions for egg purchase

1. Quality mark: When purchasing, you can check the quality mark or production date on the eggs to ensure that the eggs are legal and fresh.

2. Shelf life: Eggs usually have a certain shelf life, and choosing eggs that are far away from the expiration date can ensure their freshness.

3. Appearance: Observe the appearance of the egg shell. Fresh eggs have smooth shells with no cracks or stains. Avoid buying eggs with broken dates, as this may lead to the invasion of bacteria.

4. Smell: Smell the eggs gently, if there is a peculiar smell, it may indicate that the eggs have gone bad.

5. Size: The size of eggs is usually divided into different grades. Choose the right size according to your individual needs and formulation requirements.

6. Raw eggs and washed eggs: The surface of raw eggs is covered with a natural protective coating on the eggshell, which can maintain the freshness of the eggs. If you buy washed eggs, they may lack a protective coating and therefore have a shorter storage time.

The above content reference: Have you come to the doctor - are the nutritional values of chai eggs the same as ordinary eggs?

As an indispensable food for breakfast, eggs have always attracted attention. Ordinary eggs usually refer to the eggs of chickens, while chai eggs refer to eggs laid by old hens that have undergone a certain amount of treatment. Although these two eggs look similar, their nutritional value is different.

First of all, chai eggs have a higher protein content than regular eggs. Protein is a nutrient that the body needs to help the body maintain normal physiological functions. Therefore, chai eggs have a higher nutritional value and can provide more protein to the body.

Secondly, compared to regular eggs, chai eggs have a lower cholesterol content. Cholesterol is a lipid compound, and excessive intake can cause diseases such as cardiovascular disease. The cholesterol content in chai eggs is relatively low, which can reduce the burden on the body and help maintain cardiovascular health.

Finally, chai eggs and regular eggs do not differ much in terms of other nutrients. Whether it is vitamin and mineral content, or fatty acid and carbohydrate content, there is not much difference between the two. However, the taste and flavor of chai eggs are still slightly different from ordinary eggs, and they are more inclined to the fragrant and glutinous taste.

In summary, firewood eggs have higher protein content and lower cholesterol content than ordinary eggs in fierce ears, but there is little difference in other nutrients. Of course, the choice of slippery reed over eggs should still take into account the usual taste preferences and personal health conditions, and cannot be generalized.
