The following six kinds of people should not drink coffee:
Suffering from hypertension, coronary heart disease, arteriosclerosis and other diseases-drinking coffee for a long time or in large quantities can cause cardiovascular diseases.
Older women-coffee will reduce calcium and cause osteoporosis. After menopause, women need to add ten times the amount of calcium every day.
Patients with stomach trouble-drinking too much coffee can make stomach trouble worse.
Pregnant women-drinking too much coffee can lead to fetal malformation or miscarriage.
Vitamin B 1 deficiency-vitamin B 1 can maintain the balance and stability of the nervous system, and coffee can destroy it.
Cancer patients-drinking too much coffee is dangerous to normal people.
Close contact with coffee
Caffeine can stimulate the central nervous system and muscles, so it can refresh the spirit, enhance the thinking ability and restore muscle fatigue. Acting on the cardiovascular system can improve heart function, relax blood vessels and promote blood circulation. For the gastrointestinal system, it can help digestion and help the decomposition of fat.
Help to lose weight
I believe many people have heard that drinking black coffee can reduce weight. In fact, this is only one of the factors. Caffeine can indeed accelerate the decomposition of fat, but at the same time, it is more necessary to rely on muscle exercise to convert excess fatty acids into heat energy for consumption. If there is no coordinated exercise, excess fatty acids will flow back along the blood stream and accumulate fat again. Therefore, after drinking coffee, you need to be active at the same time to play a real weight loss effect! Coffee itself has calories, but not much. The main calories are the creamer and sugar you add when you drink coffee.
oxidation resistance
In recent years, all foods with antioxidant function are popular in the market. Generally, vegetables and fruits are rich in vitamins A, C and B, and tea, which is quite popular in Japan, are regarded as healthy foods because they are rich in antioxidant substances and can resist the harm of free radicals to human body. A few days ago, a research report pointed out that coffee contains four times more antioxidants than tea, which is more resistant to cardiovascular diseases, and coffee itself conforms to the principle of antioxidants, and it is dark in color and bitter. Each coffee contains different antioxidants because of the brewing method. For example, American coffee contains the least antioxidant, while Espresso contains the most antioxidant. After adding creamer to coffee, its antioxidant effect will not be affected.
Improve dry eyes
Foreign reports point out that coffee drinkers are significantly less likely to suffer from dry eye than non-coffee drinkers. This is mainly related to the purine component in coffee (eye drops containing purine can stimulate glands to secrete liquid, which has a certain protective effect on eyes). This is of course good news for computer people who love to drink coffee, but it should be noted that coffee itself has diuretic effect, even if some of its ingredients have protective effect, people who have already suffered from dry eye and those who have taken any medicine containing diuretic ingredients must be prohibited from taking caffeinated drinks, so as not to aggravate the loss of water in the body.
It can relieve pain
Headache caused by a bad night's sleep, or pain caused by vasoconstriction on the temple side, can be relieved by coffee, but it must be drunk in the morning or at noon (note: it is forbidden from afternoon to night).
The amount of coffee
Coffee is good for the human body, but you can't drink too much. It is advisable to drink no more than 2 cups a day. For people who are prone to nervousness and anxiety, drinking too much may be harmful.
Coffee time
It is best to drink coffee after breakfast and lunch, because it can promote the peristalsis of the stomach, help digestion, decompose the high-calorie and high-fat food that you eat, and will not stimulate the stomach like drinking coffee on an empty stomach. It is best not to drink coffee after dinner, for fear that it will affect your sleep.
If you want to stay up all night by drinking coffee, you may drink too much unconsciously, which is not good for your health.
Add chaos when you are nervous.
Caffeine helps to improve alertness, sensitivity, memory and concentration. But if you drink more coffee than you are used to, you will have the same dose of stimulants, which will cause nervousness. For people who tend to have anxiety disorders, caffeine can make the symptoms of sweaty palms, palpitations and tinnitus worse.
Aggravate hypertension
Caffeine is often combined with other simple painkillers because of its analgesic effect. However, 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, and if it is combined with emotional tension, it will have a dangerous multiplication effect. Therefore, people at risk of hypertension should especially avoid drinking caffeinated drinks when working pressure is high. Some people who have the habit of drinking coffee all the year round think that they are immune to the effect of caffeine, but this is not the case. A study shows that after drinking a cup of coffee, the blood pressure can rise for as long as 12 hours.
Induced osteoporosis
Caffeine itself has a good diuretic effect. If you drink a lot of coffee for a long time, it will easily lead to bone loss, which will have an adverse effect on the preservation of bone mass and may increase the threat of osteoporosis for women. But the premise is that people who don't get enough calcium in their food at ordinary times, or people who don't move often, and women after menopause, lose calcium due to lack of estrogen, which, together with a lot of caffeine, may pose a threat to bone. If you can enjoy it in a reasonable amount, you can still do it without choking.
These people drink coffee carefully.
hepatopath
Caffeine will prolong the time when caffeine dies in the body. Generally, it takes 2 hours for normal adults to metabolize caffeine, but it may take 4-5 hours for patients with liver disease or liver insufficiency. Therefore, patients with liver disease must be careful when drinking coffee, and it is best not to drink it after evening to avoid affecting sleep due to long metabolism time, and it is best not to exceed 1 cup a day.
Patients with digestive system diseases
I believe that people who often suffer from stomachache and gastropathy have an experience that doctors will definitely tell them not to eat irritating foods, including wine, peppers, coffee, tea and carbonated drinks.
Coffee is among them because its tannic acid can stimulate gastric acid secretion, which must be avoided if it is a patient with acute digestive diseases. After recovering, if you drink coffee occasionally, it is best to use it after meals to avoid drinking coffee on an empty stomach.
pregnant woman
Many women will pay special attention to all the food they eat after pregnancy, and drinks containing caffeine are of course listed as one of the taboos. This is mainly due to the slow metabolism of caffeine in pregnant women, which will prolong the time that caffeine stays in the body, and it will take eight or nine months for the fetus in the abdomen to clear caffeine from the blood through metabolism.
child
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 12 need to ban caffeine intake. Even Europeans and Americans who drink coffee as boiling water all day have strict restrictions on children drinking coffee.
