Drink coffee on an empty stomach

Is drinking coffee on an empty stomach harmful?

I ate very little in the morning, and now it's almost noon. I didn't eat and drank some coffee.

Many people will say that drinking coffee hurts the stomach, easy to cause nervous tension, palpitations, after drinking coffee, hands will tremble and dare not try, but it also has many unknown benefits. As long as you know how to get the right amount at the right time, you can bring the benefits of coffee into full play.

The benefits of caffeine to human body

1. Caffeine can stimulate the central nervous system and muscles, so it can boost the spirit, improve thinking and memory, and restore muscle fatigue.

2. Action on the cardiovascular system can improve heart function, dilate blood vessels and promote blood circulation.

3. For the gastrointestinal system, it can help digestion and help decompose fat.

4. Recently, a new study in the United States shows that drinking coffee can increase libido, because coffee can improve blood circulation, speed up the heartbeat, and stimulate the activity of the nervous system, so regular coffee drinkers are more sexually active than non-regular drinkers. Not only that, but also reduce the risk of impotence.

The harmful effects of caffeine

1. Aggravate high blood pressure: caffeine is often combined with other simple painkillers because of its analgesic effect, but if you take it in large quantities for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, coupled with emotional stress, it can have a dangerous multiplication effect, so people at risk of high blood pressure should especially avoid drinking caffeinated drinks during stressful times at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. One study shows that blood pressure can rise for up to 12 hours after drinking a cup of coffee.

two。 Induce osteoporosis: caffeine itself has a good diuretic effect. If you drink a lot of coffee for a long time, it is easy to cause bone loss and adversely affect the preservation of bone mass. For women, it may increase the threat of osteoporosis. But the premise is that people who don't get enough calcium in normal food, or people who don't move very often, plus women after menopause, calcium loss caused by lack of estrogen, coupled with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still stop eating for fear of choking.

The composition of coffee

Coffee beans themselves contain vitamin B and nicotinic acid, and roasted beans contain more free fatty acids, caffeine and tannins than raw coffee beans, so coffee itself has calories, but not much. The main calories come from the cream and sugar you add to your coffee.

How would you like your coffee?

Although coffee is good for the body, it must also be moderate, with no more than 4 cups of about 800-1000cc a day. Drinking too much can be harmful for people who are prone to stress and anxiety-caffeine helps improve alertness, agility, memory and concentration. But drinking more coffee than you are used to will produce the same dose of stimulants that you are used to, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus.

It takes time to drink coffee.

It is best to drink coffee after a meal, because it can promote gastrointestinal peristalsis, help digestion, decompose high-calorie, high-fat foods that have just been eaten, and are less likely to stimulate the intestines and stomach because of drinking coffee on an empty stomach. If you drink it every day, it has a good effect on the improvement of constipation.

It is best not to choose after dinner, for fear it will affect your sleep. If you want to drink coffee all night, you may unwittingly drink a lot, which is not good for your health.

These people are careful of drinking coffee.

1. Patients with liver disease: caffeine prolongs the time it takes to thank caffeine in the body. In general, the metabolism of caffeine in normal adults takes 2 hours, but in patients with liver disease or liver insufficiency, the metabolism of caffeine may take 4-5 hours, so patients with liver disease must be careful when drinking coffee, it is best not to drink it after dusk, so as not to affect sleep due to long metabolic time, and it is best not to exceed 1 cup a day.

two。 Patients with digestive diseases: I believe that people who often have stomachaches and stomach ailments have an experience that doctors will tell them not to eat irritating foods, including wine, chili peppers, coffee, tea and carbonated drinks.

Coffee is among them because the tannic acid stimulates gastric acid secretion, which must be avoided if it is in the acute stage of digestive disease. After returning to health, if you drink coffee occasionally, it is best to use it after meals to avoid drinking coffee on an empty stomach.

3. Pregnant women: many women pay special attention to all foods they eat since they are pregnant, and drinks containing caffeine are also taboo. This is mainly due to the slow metabolism of caffeine in pregnant women, the caffeine stays in the body for longer, and the fetus in the belly will not be able to remove caffeine from the blood through metabolism until eight or nine months.

4. Children: due to the incomplete development of children's liver and kidney and poor detoxification ability, the half-life of caffeine metabolism will be prolonged, so generally speaking, children under the age of 12 need to ban caffeine intake. Even people in Europe and the United States who drink coffee as boiled water all day have very strict restrictions on children's drinking coffee.

What is the effect of drinking coffee on an empty stomach?

Coffee has a certain stimulating effect on the gastrointestinal tract, and one of the effects of coffee is to increase gastric peristalsis. So generally speaking, it is not recommended to drink coffee on an empty stomach. Have something to eat before you have coffee.

How about coffee on an empty stomach in the morning?

I have to go to school in the morning, but I always feel like I can't wake up.

I'll just have a cup of plain coffee without milk or sugar to cheer me up.

Is this good for your health?

Many people drink coffee on an empty stomach in the morning. When they work in the morning, they often have a faint pain in their stomach, and some people have palpitations. The doctor said that coffee has many unknown benefits, as long as people know the right time, the right amount, can get a lot of benefits.

■ Western Medicine: drinking on an empty stomach can also be stimulating.

According to Dr. Liu Rui of Beijing Puren Hospital, coffee stimulates gastric acid secretion, so even if you drink it without an empty stomach, it will be irritating to the stomach, and people with gastric ulcers should pay more attention to it.

But at the same time, coffee is also good for the human body. To put it simply, a small amount of coffee has a stabilizing effect and a large amount of coffee has a refreshing effect. In addition, as coffee is a non-calorie drink, drinking coffee under a normal diet can also achieve the effect of healthy weight loss.

■ traditional Chinese medicine: easy to cause "stomach qi injury"

According to Dr. Wang Guowei of the Beijing traditional Chinese Medicine Hospital, traditional Chinese medicine says that "the stomach is accepted" and that the human stomach is the place where food is received. Drinking excitant coffee on an empty stomach can easily cause "stomach gas injury", thus affecting the digestion and absorption of stomach function. People with liver disease, patients with digestive system diseases, pregnant women and children are not suitable for drinking coffee.

Joint suggestions of traditional Chinese and Western Medicine:

1. It is best not to drink on an empty stomach and properly eat some bread to match. Two to three cups of coffee a day is the most appropriate amount, which can stabilize the nervous mood at work.

two。 When drinking coffee, you should drink some boiled water, hot or cold. First, it can remove bad breath in order to better taste; second, because coffee is beneficial to urine function, drinking more white water can increase urination and protect kidney function, and you don't have to worry about getting angry when drinking coffee.

How about coffee on an empty stomach in the morning?

I have to get up after five o'clock every morning to memorize words or something.

And afraid of dozing off in class.

So I drink a bottle of coffee every morning.

The kind of Yaha

But I feel sick when I go upstairs and downstairs every morning.

What's going on?

My stomach itself is not very good.

If you don't drink, you will sleep in class.

Then how to cheer you up?

Most of the time, I don't have time to drink like that, but it's usually boiled without sugar milk.

Because I've been drinking coffee for ten years.

So there is not much reaction, bt still sometimes has some bad physical reactions.

My stomach is not very good either.

So it makes my stomach cramp more frequently.

Because coffee is irritating to the stomach.

In addition, it will speed up the heartbeat

After all, it has a regulating effect on nerves.

Over the years, I have tried tea several times because of stomach ailments.

But it really doesn't cheer me up.

It's like sometimes I drink coffee to cure insomnia.

Sometimes tea doesn't work for everyone.

It is true

A lot of psychological factors can not be ruled out in the process.

Because you're more likely to be in this situation.

As soon as I saw the title, I planned to resolutely fly the flag of opposition.

Because the physical damage is too great.

But it's Yaha.

I don't know which one you bought.

Because it also has black coffee and sugar milk.

If we calculate it according to the normal 1:1:1 normal sugar milk, according to its proportion of ingredients, it's actually all right.

It's not that serious.

Even the amount of caffeine in a can.

That is,

Now, for you, it's actually the subconscious mind that plays a more important role.

Synthesize all kinds of favorable factors.

My personal advice is

In this case, first of all, it is necessary to have a glass of water at the beginning of the morning.

In fact, when you drink Yaha, you'd better match some bread with whole wheat or whole grains.

Or eggs, not greasy.

If you can't eat, you can add some sweet and sour ketchup.

Because you still need to pay more attention to your brain.

It takes a lot of brains.

You know,

Sometimes it's not enough to be sleepy.

It is not enough to keep your brain awake, but also to be able to maintain flexible thinking, including memory.

So whole grains and eggs are for you.

And because of eating with them, the only side effect that Yahari may not have has been offset.

For your body, it can be regarded as a morning Lego.

For your mind, the "stimulant" has been injected, so you should wind it up and cheer up.

One thing to remind you, even so, just the right amount.

Breakfast is good, not too much.

Because if you eat too much breakfast, you may start to fight before your eyelids can be read.

The blood army has been mobilized by your stomach to work.

Under the condition that the total amount is constant

Of course there are fewer troops in your head.

So . It's natural to be sleepy.

So don't be too full

But it must go well with it, even a piece of bread.

Nong Xiaodai?

Then remember to put soda biscuits in your schoolbag.

Getting up early to decide your so-called "breakfast" is actually too early.

If you don't want to waste the fourth class every morning.

You can add something at the right time.

In order to stay up until lunch.

Because when you're hungry, your brain is not ischemic, it's lack of oxygen.

It's easy to distract.

Let alone those who are hungry.

So . Remember

From the perspective of "experienced people", I have always been like this.

Because no matter when I was a student or during the working period,

For a long time, I basically belong to those who sleep 4 hours or less a day.

At the same time, it requires mental work.

Plus I've been a vegetarian for a long time.

Therefore, it is all done in this way, and it is still effective for mental maintenance.

Here's what the first guy said about losing weight.

In the case of classmate Xia, because Yaha is sugary, remember that three-in-one coffee will only gain weight if you don't eat and drink all day.

If you want to lose weight with coffee without harming your body

Remember

Don't sit down half an hour after lunch every day.

What do you like? you'd better make coffee.

Because drinking black coffee half an hour after lunch is very effective for eating and relieving fatigue.

Yes, it's black coffee.

That is, no sugar, no milk, no bad taste.

I wasn't used to drinking like this for the first time in high school.

Later, it was found that the coffee was much less bitter when it was boiled and frozen in the refrigerator.

But alcohol is also reduced.

But if you're not suited to the bitterness of pure black coffee at first,

And it is not with the mentality of fine coffee culture.

Then it won't be a big problem if you freeze it.

It's not so hypocritical.

No one will come forward and criticize "too unprofessional" and "desecration of coffee culture".
