The so-called radishes and vegetables have their own preferences, and people have different tastes. Some people don’t like seafood, some people don’t like coriander, some people don’t like large intestines, and some people don’t like eggplant.

Some people don't eat meat for a day and feel uncomfortable all over, while some people just eat a little more meat and feel indigestion and feel uncomfortable all over.

Some people can eat any kind of meat, some people can't smell pork, and some people like the smell of mutton, and some people, who didn't eat meat before, changed the environment and started to eat meat, and gradually became very meat-eating. .

The above situations all show that there may be many reasons for the human body to choose food.

Friends often tell me that I didn't like meat before, and I haven't eaten meat for a long time. Now I'm on a low-carb diet, and I want to eat more meat, but I feel uncomfortable when I eat meat. What should I do?

Today we are going to talk about why some people feel uncomfortable when they eat a little more meat?

Whether you like the taste of meat may have something to do with your genes. There is a study in the journal PLoSONE that found that genes affect your food choices.

Most people think that we choose food based on its texture and taste, where taste may prevail, but some people just don't like the taste of meat by nature.

→ How genes affect your sense of taste

The reason why people can smell is mainly through certain specific tiny chemical receptors, which are located in the nerve cells in the nose. In our genes, there are about 400 different receptors, and we can detect about 10,000 kinds. different smells.

Some of these receptors detect the steroid androstenone, a source of taint in boars.

Pig farmers know that uncastrated boars have a strong smell of taint, so many boars in the market have been castrated.

Some studies have found that when there are 2 copies of a certain gene in the body (let's call this gene X), this person can smell this odor, and about 70% of people can smell this smell.

For those who are particularly sensitive to smells, they will find it very disgusting and fishy.

And for some people, you can smell it too, but they feel it smells good, it's a special scent.

In contrast, when there is only 1 copy of this gene X in the body, the receptors will not be troubled by the taste of this androstenone, and they can hardly smell it, or can only smell it very lightly.

So, is there a simple taste test that can tell if you carry 1 copy of the X gene, and whether the gene affects how you smell cooked meat?

The researchers recruited 23 healthy people, 13 normal people and 10 people with a particularly sensitive sense of smell.

First, 3 cups of water were prepared, and androstenone was added to 2 cups, and the subjects picked out different cups of water by smelling them.

If they smell it, they are considered olfactory sensitive, and if they are wrong, they are considered insensitive.

The subjects were then asked to eat cooked pork (which had different levels of androstenone) and again to rate their taste.

Then, the researchers tested the genes of these people, and found that the testers with 2 copies of the X gene in the body could choose the glass of water, and they could also eat it, and the cooked meat also had the same taste.

People with only 1 serving of the X gene can't smell the taint and think pork is delicious.

It's also worth noting that half of those who didn't smell androstenone at first would gradually start smelling it if they smelled it every day for 21 days.

This research suggests that the ability to smell is not just driven by genes, but also by experience.

Therefore, genes affect our food choices, and experience also affects people's food choices. The experience of eating meat or not is also discussed in almost every point below.

Everyone's digestive system is different, and their ability to digest meat is also different, and for some people, eating a little more meat can make them bloated and nauseated.

→ Digestive system has adapted to a lot of fiber-containing foods

Because some people don’t eat meat for a long time, the digestive system cannot secrete a large amount of enzymes that digest meat. If you eat a little more meat, it will be difficult to digest and stay in the abdomen. .

→ Gut microbes

The microbes in the gut are fed by long-term food intake. If you don’t eat much meat and change the food source all of a sudden, the microbes in the gut that originally depended on plant fibers for survival may become disordered, or even turn around and eat them. Human intestinal mucosa.

When the mucosa of the intestinal wall is destroyed, the human body will be easily interfered by foreign pathogens. If you feel sick after eating meat, it may be the body's reaction to certain pathogens.

It may also be that the meat itself is not clean, contaminated, or spoiled. Eating these will introduce more pathogenic bacteria, which may accelerate the damage to the intestinal mucosa.

In addition, out of the instinct to protect the child, some women will be extra sensitive during pregnancy, and they will be more picky and cautious about meat, and sometimes they will feel sick when they smell a certain meat.

As mentioned above, in addition to genes, eating experience also plays a key role in food selection.

If you always eat porridge, the stomach acid may become less and less, and it may also cause gastric acid reflux, because after a large amount of carbohydrates are ingested, they enter the intestinal tract and break down, which will produce a lot of gas and form a lot of pressure, and the pressure will continue until The tail may eventually open the sphincter gate, causing acid reflux.

For a long time, the digestion ability of the stomach will become worse and worse, and the ability to digest other foods, including meat, will naturally become worse.

→ Too little stomach acid, eating meat is not good for digestion

In fact, most digestive problems and diseases are caused by stomach acid, but too little stomach acid, not too much.

As soon as acid reflux occurs, many people think it is due to excess stomach acid and start taking acid-lowering drugs. These drugs are really harmful. This is a serious medical misunderstanding that has adverse effects on millions of people.

True hyperacidity is rare. Many people feel indigestion after eating a little meat, belching after eating sweet potatoes, fullness after eating a few mouthfuls, abdominal discomfort, diarrhea or constipation, which may all be achlorhydria Performance.

→ Stomach acid is really important for your digestion

Stomach acid stimulates the secretion of enzymes, hormones and neurotransmitters related to digestion to ensure the smooth progress of the digestion process. If there is not enough gastric acid, it will affect all aspects of digestion and eventually cause indigestion.

Stomach acid plays a key role in protein digestion. If the stomach acid is insufficient, the protein in the stomach cannot be broken down. After these undigested proteins enter the small intestine, food allergies or intolerances can also occur.

There are other reasons that cause problems with meat digestion.

When you start eating with your mouth open, your digestive system is already working. First, in your saliva, there are two digestive enzymes that work to break down carbohydrates and fats.

When proteins enter your stomach, protein-digesting enzymes break them down into smaller chains of amino acids that travel into the small intestine.

Therefore, in order for meat to be better digested and absorbed, the human body needs to produce specific digestive enzymes, such as gastric protein digestion enzymes, to decompose meat nutrients into amino acids, vitamins and minerals.

If the protein digesting enzymes in the body are insufficient, the ability to digest meat will naturally be insufficient, and the level of protein digesting enzymes in the body is also related to the food we eat.

In a healthy physical condition, if you eat enough vegetables and meat, the protein digestive enzyme level of the human body will be normal, and there will be no shortage of secretion. However, if you do not eat meat for a long time, the digestive enzymes responsible for digesting meat will also be insufficient.

In addition, as mentioned above, too little stomach acid for a long time will also lead to too little secretion of protein-digesting enzymes.

Many times, we eat meat with other foods.

For example, if you eat braised pork, you will have rice; if you have beef burgers, you will have bread, you will have fries and coke, and if you have fried chicken, you will probably have some beer and hash browns.

After eating these foods, if you feel uncomfortable in your body, it is not necessarily the problem of the meat itself, but it may also be the food that goes with it, causing your bloating, acid reflux and other problems.

And these are usually high-carb foods that go with meat, which may be a problem for people who often eat burgers.

You can use the exclusion method. If you eat meat alone, or eat other things alone, look at the body's feedback.

There are many elderly people around me. They can only drink porridge and can't eat meat. If they eat a little meat, they feel uncomfortable and can't digest it. Of course, some elderly people can't eat meat.

Many elderly people feel that eating anything is not as comfortable as drinking porridge. If this continues for a long time, problems such as insufficient protein, malnutrition, osteoporosis in the elderly, and chronic diseases will become more and more serious.

In addition to being good for digestion, porridge itself has no nutrients, only some calories. The nutrition of eight-treasure porridge is not special, and it is not a treasure.

Whether it is young people who want to grow taller, or old people to maintain health and improve nutrition, they must eat more vegetables and meat.

After reading my articles and cases, many friends also want to try a low-carb diet and eat more vegetables and meat, but when they try to eat more meat, they find that their bodies can't stand it and feel uncomfortable.

This article introduces the reasons why eating more meat is uncomfortable from the perspective of genes, intestines, low stomach acid, protein digestion enzymes, and long-term non-eating meat.

In fact, many people feel uncomfortable after eating more meat. It may not be caused by a certain reason. In most cases, it is the result of the combined effect of several factors.

For example, drinking porridge for a long time, eating a lot of rice, noodles and sugar, often not eating meat, or eating very little meat, is likely to lead to low stomach acid, insufficient secretion of protein-digesting enzymes, and the ability of the intestines to digest meat continues to decrease.

Fortunately, the body's ability to digest and absorb meat can also be slowly adjusted and exercised through diet.

Therefore, friends who want to eat more meat can take it slowly and gradually reduce the intake of rice noodles and sugar. If eating more meat is uncomfortable at first, then start with a small amount and gradually increase it. The important premise is to ensure that the body is healthy. acceptable and comfortable.

Within the range that your body can accept, you may gradually find that your body's ability to digest and absorb meat gradually increases, and eating meat is not as uncomfortable as before.

If you really can't stand the taste of pork, don't force yourself to eat beef and mutton.

In general, eat less rice, noodles, sugar, and more vegetables and meat, the healthier your body is, the more flavorful your life will be.
