Why do people perceive taste so differently?

It belongs to the advanced excitatory impulse, which is related to the brain, and the things that human brain cells develop and remember are not the same, so the brain nerve empathetic chain is also different, and the empathetic chain I said is a little related to conditioned reflexes, but it is different It is not a physiological embodiment, but the result of imagination. It's like drooling when you look at the sour, most of us are like this, but for example, perfume, when a person smells the perfume, he will immediately associate other things, and everyone will associate it differently and will have different feelings. It will be clearer to explain it this way, but in short, it is the difference in brain associations that make people react differently.

World Science and Technology Report [News: vinegar, lemon, sour plum, some people love to eat these sour things, but some people can't stand it when they hear it. Researchers in the United States have found that different people have different feelings about sourness, and there is a genetic influence in this.

Researchers at the Monell Center for Chemical Sensation, an American research institute for taste and smell, reported that they studied 74 pairs of identical twins and 35 pairs of fraternal twins, comparing their response to acids.

Taste response, which is analyzed by computer models for genetic factors and environmental factors.

Identical twins have identical genes, and the chances of fraternal twins being genetically identical are greatly reduced. If identical twins feel more sour than fraternal twins, it suggests that there is a genetic influence on the sour taste.

The results of this study showed that genetic factors played a role of about 53 in human sour taste sensitivity, which was higher than that of environmental factors.

The discovery could help scientists find sour taste receptors in the human body, which have previously been helped by genetic studies. Scientists say that the evolution of taste may be related to different people's preferences for food, that is, nutrition. Deepening the understanding of the entire taste system and understanding why there are differences in taste perception between people is expected to be used to change people's taste perception of food and help people develop healthier eating habits.

The effect of genes is different from that of the receptors of the nasal mucosa.

The mucous membranes in the human nose react differently to taste, for example, when someone smells gasoline and others can't.

The body odor is stinky, and I think most of it may be fox odor. It is still necessary to pay attention to personal hygiene. And then there's the fact that you probably don't reject him genetically.

There is a saying that if he doesn't have any body odor that you still think is fragrant, then it may be that your genes have chosen him.

Some people often take a bath and pay more attention to the maintenance of hygiene!

And the ones that smell more stinky are basically people who smoke and drink, and they don't take baths much.

Habits: Our body odor is very related to our daily habits. Take personal hygiene as an example, if you usually love hygiene, brush your teeth frequently, take a bath frequently, and change your clothes frequently, then your body will not have obvious body odor, and there will be a faint fragrance because of hygiene and cleanliness, which is the real body fragrance, of course, it may also be the fragrance on your clothes.

Human body odor is made up of a mixture of secretions from various glands, and the most influential is the secretion of apocrine glands.

Human sweat contains a substance called "butyrate", and the concentration of this substance determines your smell to a certain extent. Lower concentrations will produce aromatic body odors, and higher concentrations will produce fishy odors.

Body odor is a specific taste produced when metabolites in the body are excreted from the body through the mucous membrane. Body odor varies greatly among different ethnic groups, and there are also some differences between different individuals.

Eating habits can lead to different body odors. According to surveys, countries such as Europe and the United States, which often eat meat, have a strong body odor for both men and women, while areas with a predominantly vegetarian diet have a light body odor.

Some people have fox odor, and some people, especially boys, exercise a lot, and the smell of sweat is very heavy if they can't be cleaned in time.

The fragrance of the body is related to the shower liquid and shampoo, which are all related, but the body of some people has a smell, which should be the sweat of each person's body is different.

This is often related to people's living habits or eating habits, so it is different from person to person, and the physique is different.

Sweat secretion, let your body odor emanate: Sweating is a mechanism for the body to protect itself, through the excretion of sweat to lower one's body temperature. More than 95% of sweat is water, including sodium chloride, 1% and 2% urea, lactic acid, fatty acids and other components.

When the content of urea and ammonia in sweat is excessive, it will cause the human body to emit odor.

It has to do with food: If you like to eat heavy foods like leeks, garlic, and chili peppers, these foods will not only make you smell bad. At the same time, these food components can also be absorbed through the digestive system, and then transported by the bloodstream to all parts of the body, and the excess substances may be excreted by the sweat, resulting in a certain odor.

Deodorant precautions.

Try to eat less meat, because the physique of carnivorous food will be acidic, and too much acidic substances will be produced during the metabolic process, and the body fluids will gradually acidify, resulting in the so-called "smell", especially the armpits, which are more likely to emit special odors. Indians and Pakistanis love to eat curry and cheese, which also has a bitter taste on their bodies.

After eating or drinking coffee, there is often some taste left in the mouth, so remember to maintain the habit of drinking more water to reduce the embarrassing situation of smelling bad smell in your mouth.

This sentence is a rhetorical question that can be changed to a declarative sentence: it doesn't taste special.

How to change a rhetorical question to a declarative sentence: the four-step method.

Step 1: There is "no" to "no", no "no" and "no".

Change the affirmative word in the rhetorical question to a negative word, or change the negative word to an affirmative word.

Step 2: Remove rhetorical particles and interrogative particles.

Remove the rhetorical modal words (how, how, wouldn't it, etc.) from the rhetorical question. Remove the interrogative particle at the end of the sentence (what, what, etc.).

Step 3: The question mark becomes a full stop.

Replace the question mark at the end of the sentence with a full stop.

The rhetorical question plays an emphatic role in the article, so when changing the rhetorical question to a declarative sentence, it is best to add some words to express emphasis.

For example, how can we not believe what we say?

When changing to a declarative sentence, change "can" to "can't", remove "how", remove "Yandan", and change the question mark to a full stop. The declarative sentence that has been changed to read: We cannot be untrustworthy.

Summary. The complex aroma of the euphoria they received an amazing result: an almost infinite variety of food flavors is based on 230 major flavoring agents.

Each food has a unique aroma** and is made up of core groups of only 3 to 40 of the 230 key flavors – at specific concentrations. The smell of these small groups gives them a unique aroma and a wide variety of foods from pineapple to wine to grilled meats. "For example, the smell of sour cream butter is made up of only three key molecules, and the smell of fresh strawberries is 12," explains Professor Peter Schieberle of the German Centre for Food Chemistry Research.

The frontrunner is Cognac: for the spirit of the classics, 36 key molecules must interact.

This is due to the action of the chemicals they themselves contain. Let's start with acids. Let's talk about sour grapes, which can sour teeth, it contains a substance called tartaric acid, and sour apples contain malic acid, and sour oranges contain citric acid, and so on.

The sour taste buds of the corresponding person are distributed on both sides of the front of the tongue, so the sour sensation always comes from the side of the tongue. Plants that have a sweet taste are because they contain sugar in their bodies. For example, glucose, maltose, fructose, lactose and sucrose.

The sweetest thing here is fructose, and fructose is more conducive to digestion and absorption by the human body; The second is sucrose, no wonder sugarcane, which is dominated by sucrose, and sugar beets taste so sweet. The sweet taste buds that feel the sweetness are distributed on the tip of the human tongue, and if you want to know whether a certain fruit is sweet or not, you can lick it with the tip of your tongue. Many bitter plants are because they contain alkaloids, such as Coptis chinensis, which is famous for its bitterness, which contains a lot of berberine; Cucumbers and bitter gourds have a bitter taste because they contain acid sugar bodies.

The bitter taste buds are mostly distributed at the base of the human tongue, and when the bitter food is eaten, the bitter taste lingers in the human throat for a long time. The spicy taste of the plant, the reasons are complex. Chili peppers are spicy because of the capsaicin they contain; Tobacco is spicy because it contains nicotine; Bear.
