It is said that breast cancer sisters need "nutrition", and appropriate nutritional therapy can not only help us increase treatment tolerance, improve treatment efficacy, and improve quality of life, but also reduce the risk of recurrence and death of breast cancer patients [1].
And the average price of about 1 yuan an egg is often the first choice for everyone to supplement nutrients (protein), usually nothing to do with the small video of the mutual aid gentleman noticed: there is also technology in eggs......?

Most breast cancer patients want to avoid foods containing estrogen (there are estrogen receptors in cancer cells, once combined with estrogen, it may promote the rapid growth and even metastasis of breast cancer cells) and make up for the "pit"?
01 Do the hormones in eggs threaten the health of breast cancer patients?
The answer is that breast cancer patients can eat natural eggs purchased through regular channels.
Here's why:
First of all, there are "endogenous hormones" and "exogenous hormones".
Tips:
■ Endogenous estrogen: mainly in the ovaries of the human body, a small amount of it exists in the liver, adrenal glands, placenta, testicles, and some of them are converted from androgens under the action of aromatase.
■ Exogenous estrogen: mainly derived from synthetic estrogen, food, drugs, etc.
Secondly, eggs do contain hormones, such as the progesterone in egg yolk, which is a natural progesterone [2].
However, as the saying goes, if you don't talk about dosage, you are a hooligan, and a meta-analysis published in the Journal of Oncology and Nutrition in 2021 found that there was no significant association between egg intake and breast cancer risk [3], and eating too many eggs and elevated cholesterol may indirectly affect the health of breast cancer patients.

So, we should pay attention not to eat too many eggs.
As for why the emphasis is on formal channels, it is because some unscrupulous merchants will sell us some "black-hearted eggs", which are the so-called "antibiotic eggs".
The national food safety supervision department has reported that antibiotic residues have been detected in multiple batches of eggs and layer tissues [4]!
There are indeed some black-hearted merchants on the market who illegally add various hormone drugs to the feed, which is "artificially added" exogenous hormones.
Antibiotics are actually one of the drugs used to prevent and control diseases in poultry such as chickens and ducks.
It is understandable that chickens should "take medicine" when they are sick. However, unscrupulous traders may have illegal overdose or lack of understanding of the use of antibiotics in poultry, which may lead to the deposition of antibiotics in eggs, which may cause gastrointestinal disorders, neurological diseases, allergies, tissue damage, and in severe cases, carcinogenic, teratogenic, mutagenic, and even death [5].
To sum up: you have to go to regular channels to buy eggs!
02 Don't eat these kinds of bad eggs!
Although it is impossible to distinguish between hormone eggs and antibiotic eggs with the naked eye, some bad "eggs" can be identified with your eyes! (Believe yourself, your eyes are rulers!)
1. Loose yolk eggs
How to judge loose yolk eggs: When you pick up an egg and shake it, there is a feeling of concussion, and it is very likely that this kind of egg is not fresh.
But this method may be attacked by the eyes of the merchants, so everyone shakes it lightly.
2. Hairy eggs
That is, "chicken fetus", that is, chickens that have not fully hatched, are often eaten as a tonic in many areas. In fact, the nutritional value of hairy eggs is not high, and they often contain a lot of pathogenic bacteria.
3. Soft-boiled eggs
Eggs that are not fully cooked are called soft-boiled eggs, but they may also contain some unkilled salmonella and parasites.

Tips:
If you must eat soft-boiled eggs, it is recommended that you buy "raw eggs" with clear labels in regular supermarkets. These eggs must be kept at low temperatures, and remember to keep an eye on the date of manufacture.
4. Rotten eggs
These eggs can smell distinctly foul when opened, and the yolk and egg white have long since become a loose puddle of gray-green liquid. Sisters, believe in your sixth sense, smell and look at the wrong things and throw them decisively!
5. Moldy eggshells
In a humid environment with poor air circulation, eggshells can become moldy and spotted.
6. Cracked eggs
Cracks in the shell of eggs can also cause bacteria to sneak in, don't eat them!
Everyone usually pays more attention to these small details when eating eggs to prevent accidental eating of "bad eggs".
03 Questions about eggs: What are 100,000 "eggs"?
Q&A time about eggs begins:
The nutritional value of native eggs > ordinary eggs?
Judging from the current literature, there is not much difference between native eggs and non-native eggs in terms of nutritional value, and the protein, fat, vitamins and other nutrients of all eggs are basically stable.
But some sisters will say that the yolk of native eggs is more yellow in color, so the nutritional value will be higher.

In fact, the color of the egg yolk is often related to the feed that the chicken eats, if the chicken eats more vegetables, and the vegetables contain more carotene, the egg yolk is yellowish. As for the difference in taste, it is explained that it may be because the local eggs are more miscellaneous.
To sum up, Mutual Aid Jun personally thinks that if economic conditions permit, there is nothing wrong with giving priority to local eggs (Mutual Aid Jun himself also prefers native eggs), but it should be noted that local eggs should not be purchased from retail investors, because some retail eggs' native eggs may not be fresh, or the sterilization process is not up to standard.
Is eggshell color related to nutritional value?
The color of the eggshell has nothing to do with the nutritional value, the color of the eggshell is white, yellow, green, etc., but the nutritional difference is not large.
What is the difference between egg white and egg yolk nutrition?
Many people know to supplement protein during weight loss, but they think that egg yolks are high in cholesterol and fat, so they will "discard" egg yolks when eating eggs.
But the truth is that this wasteful behavior is completely unnecessary. (Is it possible that it is not eggs that make people gain weight, but milk tea, barbecue, and hot pot?)
Here are the nutritional facts for egg whites and egg yolks [6]:
| Egg white yolk nutrients | ||
| ingredient | protein | yolk |
| water | 84.4%~87.7% | 44.9%~51.5% |
| protein | 8.9%~11.6% | 14.5%~15.5% |
| fat | 0.1% | 26.4%~33.8% |
| sugar | 1.8%~3.2% | 3.4%~6.2% |
| Minerals | 0.6% | 1.1% |
How many eggs do breast cancer patients eat a day?
According to the recommendations of the Balanced Diet Pagoda for Chinese Residents (2022), eggs have a high nutritional value, and it is recommended to have 1 egg per day (equivalent to about 50g). However, breast cancer patients with hypercholesterolemia should take care to reduce their egg intake.
