In the process of eating, we will be more critical about certain foods, that is, only eat foods that we like or are accustomed to, and hate specific foods, such as coriander. This is not a patent for children, many young people, even the elderly will be picky eaters. However, the same is picky eating, but the situation is different, because picky eating is sometimes an objective reason for the body, not willfulness.
01
Not loving coriander is innate
People are picky eaters, sometimes determined by their own genes.
Maybe you will notice that some people don't like to eat coriander, and when asked, they will say that they hate the smell of coriander.
In this regard, studies have found that whether people like to eat coriander is closely related to the OR6A2 gene. The gene is an olfactory receptor gene that is sensitive to aldehyde-based chemicals, and the unique source of coriander's odor is the aldehyde-like substance.

If the human body contains the OR6A2 gene, it will reject the smell of coriander, and the coriander eaten by such a group of people is the smell of soap and the smell of the stinky big sister in the grass, thinking about it, it is really difficult to digest.
In addition, different people have different sensitivities to bitterness, such as kale, some people feel crisp and delicious, and some people feel bitter.
This is because of the benzothiouracil and propyl thiouracil contained in kale, and extremely sensitive "super tasters" can have strong feelings about these substances in bitter vegetables and reject these foods.
Researchers at the Museum of Nature and Science in Denver in the United States say this bitterness sensitivity is related to a mutation in the gene TAS2R38.
So we will see that some people eat coriander, kale, etc. as delicacies and eat them with relish, while others treat them as garbage, which is actually genetically determined and innate.

Physical problems can not eat, it is not my fault
In addition to genetic differences, around us, some seemingly picky eaters actually have their own unavoidable grievances - this kind of picky eating is usually caused by allergies or gastrointestinal problems.
# Causes of allergies
Perhaps you will notice that some people around us, when eating some specific foods, the body will get pimples or itching, which is a symptom of allergies. Different people will also have different allergy symptoms.
For allergies, industry insiders investigated and analyzed that people with allergic constitutions will have outbreaks of allergy symptoms as long as they ingest related foods.

Clinical medical findings most people with allergies will have allergies to eight types of food, including milk products, shellfish, peanuts, eggs, nuts, fish, wheat, soybeans these 8 types of food, is also often said to be the eight major allergens.
However, with the increase of age, the symptoms of such people eating foods that cause allergies will also improve.
# Gastrointestinal causes
Gastrointestinal problems can also lead to picky eaters, which is not new. The condition of each of our individuals is different, and the gastrointestinal situation is naturally different. So for the same food, some people's stomach can digest it, while others can't digest it.
For example, some people don't drink milk. Tadpole Jun is, when he was a child, drinking milk would cause diarrhea and bloating, and his mother said that he could not drink milk because he was not blessed...
Later (that is, now) it was known that because milk contained lactose, it was needed to be broken down into simple sugars by lactase after entering the human intestine, which could be absorbed and utilized by the human body. Because of the lack of lactase in the intestine, Tadpole Jun cannot decompose lactose, and will have the discomfort mentioned above.
Therefore, it cannot be said that Tadpole Jun is an unblessed person, that's it.
There is also a category of people who are picky eaters because of the lack of certain substances in the body.
For example, zinc, this element in the human body has a lot of roles, zinc deficiency not only affects the baby's growth and development, but also leads to the decline of their taste bud function, thereby reducing taste function, the clinical manifestation of zinc deficiency is that children are picky eaters.

It may also be an injury
There are many small partners who are not born with aversion to certain foods, but eat for a period of time to have disgust with such foods and do not want to eat. This situation is called "eating wounds".
Why do people have such a situation of eating and injury?
Maybe everyone has had such an experience, that is, the food that you like again, if you eat it every day, you will lose interest in this type of food. In fact, this is a manifestation of "the fullness of a particular sense".
In this regard, the American online media Vox has done a test, that is, after the subjects have eaten cheese macaroni, they will send cheese macaroni as dessert, and found that the subject's level of interest in this dish has dropped from 6.2 points (10 points) to 1.3 points.
In addition, the length of time that each person feels sad about a certain food varies greatly. For example, eggs, some people eat for a week in a row and feel bad, while others eat for a year to have this feeling.
