Benefits of moderate coffee consumption:
1, promoting digestion and improving intestinal function.
Pure coffee tastes bitter, which may be unacceptable to many people, but it is rich in phenolic compounds, which can promote detoxification and metabolism of the body and increase the number of flora in the intestine. People who insist on drinking coffee may have cleaner and healthier intestines.

Drinking a cup of coffee when you are sleepy can wake up in a short time, which is one of the most obvious benefits that everyone can feel.
Drinking coffee can promote dopamine secretion in the body. This substance can promote the regulation of emotions, improve the excitement of the brain and refresh the mind. If you are tired of work, drinking a cup of coffee may improve your efficiency.
Drinking coffee in moderation has many health benefits, but it does not encourage everyone to drink coffee in droves. We should keep a rational attitude. Not everyone is suitable for drinking coffee, and there are some things to pay attention to when drinking coffee. It's really good to drink right, but it's harmful to your health if you drink wrong.

Do women drink coffee to "accelerate aging" or "delay aging"? The answer is surprising.
The doctor said: female friends can delay aging by drinking coffee in moderation, but drinking too much coffee will accelerate aging. In short, drink coffee in moderation.
For most Americans, coffee is an essential drink for breakfast and the biggest source of antioxidants for Americans. Caffeine in coffee is a powerful natural antioxidant, which can not only delay the aging of the body, but also refresh the mind.
Drinking one or two cups of black coffee every day can not only better absorb antioxidants, but also absorb caffeine that is harmless to the human body. But if you drink too much coffee at one time, or drink a lot of coffee for a long time, you will have problems such as insomnia, palpitation and arrhythmia.
Studies have found that the healthiest antioxidants are fresh vegetables and fruits.
If you have the habit of drinking coffee during work and study, it is best to drink it within 20 minutes after brewing, otherwise antioxidants will be oxidized in the air, and even if you drink it, it will affect the effect.
Drinking coffee can only refresh you in a short time. If you drink a lot of coffee for a long time, it will accelerate brain aging and blood pressure will rise to a certain extent.
Although people say that drinking coffee can refresh you, drinking too much will do harm to your health, lead to insomnia and dreaminess, and accelerate brain aging, so don't drink too much coffee.

Five taboos you must know when drinking coffee.
Taboo 1: Drink too much coffee in a short time.
Drinking a lot of high-concentration coffee in a short period of time may increase the burden of heart operation and cause symptoms such as accelerated heartbeat and arrhythmia.
Many people will feel flustered and breathless after drinking coffee, because they can't stand high doses of caffeine, which has a direct impact on the heart and may even induce heart disease.
Taboo 2: Drink coffee on an empty stomach.
Caffeine contained in coffee can accelerate human metabolism. Drinking coffee on an empty stomach may cause palpitation and palpitation, which may aggravate the symptoms for patients with hypoglycemia.
At the same time, caffeine can stimulate the stomach to secrete too much gastric acid. If you think that your gastrointestinal function is declining, or you suffer from gastrointestinal diseases, it will cause great stimulation to your stomach. Therefore, I suggest you have a cup of coffee after breakfast in the morning.
Taboo 3: People with calcium deficiency often drink coffee.
Foreign related research shows that drinking coffee will accelerate the loss of calcium in the body. Drinking coffee twice in a row will lose 10~ 15 mg of calcium in the body, and tannic acid in coffee will reduce the absorption and utilization rate of calcium in the body.
This shows that the elderly, children, pregnant women and other people who are prone to calcium deficiency are not suitable for drinking coffee. At the same time, people who often drink coffee should pay attention to calcium supplementation to neutralize its effects.
Taboo 4: Drink coffee with alcohol.
Drinking coffee and wine at the same time, or drinking coffee after drinking, will bring harm to your health.
Alcohol can inhibit brain activity, while caffeine can stimulate the central nervous system and muscles and accelerate blood circulation. If wine and coffee are drunk together, it will increase the burden of cardiovascular operation and aggravate the damage of alcohol to human body.
Taboo 5: Pregnant women drink coffee.
Although the FDA of the United States stipulates that there will be no obvious problems when pregnant women consume 150mg of caffeine every day, it is difficult for us to accurately grasp how much we consume today in real life.
After all, in addition to coffee, tea, cola, chocolate and other foods all contain caffeine. Excessive caffeine can lead to miscarriage of pregnant women or birth defects.

Extended reading-Can drinking coffee delay menstruation?
Generally speaking, drinking coffee normally will not lead to delayed menstruation. If one cup a day is a normal dosage, normal physique should not affect the physiological cycle.
However, for some female friends, if a large amount of caffeine is ingested at one time, it will cause excessive excitement of sympathetic nerves and emotional tension, which will lead to premenstrual syndrome and easily affect the discharge of menstrual blood.
Usually, it is no problem to limit caffeine intake to less than 300 mg during physiological period, that is, it is no problem to drink about 250cc of coffee every day 1 cup, but if you drink too much, it is easy to have PMS or aggravate discomfort.
And menopausal women, due to the decrease of estrogen, bone loss is faster, so they should supplement calcium, reduce caffeine intake, avoid osteoporosis, and relieve hot flashes.
When drinking coffee at ordinary times, try not to add sugar or extra plant fat powder, so as not to affect human health.
