Coffee, as a refreshing and anti fatigue drink, has become a daily necessity for office white-collar workers. Like Chinese tea, coffee is one of the most popular drinks in the world. Do you know the advantages and disadvantages of drinking coffee? Let me have a look.
Benefits of coffee
1. relieving alcohol
Coffee has the function of dissolving wine. Drinking coffee after drinking alcohol will make acetaldehyde, which is transformed from alcohol, oxidize rapidly, decompose into water and carbon dioxide, and discharge out of the body. Chlorogenic acid in coffee can avoid alcoholism.
2. eliminate fatigue
Studies have shown that moderate caffeine can enhance competitive performance. Now some preliminary studies show that muscle cells exposed to caffeine are essentially the same as training. Of course, that doesn't mean that having a cup of coffee is the same as exercise, and scientists say the study could help explain the positive effects of coffee on endurance.
3. Prevention of gallstones
For caffeinated coffee, which can stimulate gallbladder contraction and reduce cholesterol in bile, which is easy to form gallstones, the latest Harvard University researchers found that men who drink two or three cups of coffee a day have less than 40% chance of getting gallstones.
4. radiation protection
Radiation produced by radiation has become a great enemy to people's health. Especially the radiation of household appliances, such as computers, televisions, microwaves and so on. A recent study found that coffee can protect mice from radiation, which may also be applicable to humans.
5. Alleviate aging
As coffee has the function of promoting kidney function and diuresis, it can help the body to discharge the metabolic waste in time. Coffee also contains flavonoids, whose antioxidant effect is far more than vitamin E, and it has the function of beauty, beauty and anti-aging.
6. lose weight
Coffee contains magnesium and potassium, which helps the body to use insulin, regulate blood sugar level, and reduce the desire for sweets and snacks. Coffee can help you burn fat. Caffeine helps fat cells break down fat and use it as a fuel for exercise.
The disadvantages of drinking coffee
1. Cardiovascular disease
People suffering from hypertension, coronary heart disease, arteriosclerosis and other diseases can cause cardiovascular disease by drinking coffee for a long time or in large quantities.
2. Insomnia
Caffeine has an exciting effect. Drinking too much coffee at one time will worsen your mood. When the average person absorbs more than 400 milligrams (4 cups) of caffeine every day, it will bring negative effects, make people fidgety and make trouble. If you drink coffee before you go to bed, you will lose sleep because your spirit is too excited.
3. Loss of appetite
Caffeine refreshes the mind because it excites the sympathetic nervous system, and the side effect is loss of appetite. When drinking coffee on an empty stomach, it will stimulate the stomach and increase the secretion of gastric juice, which is not good for patients with gastric ulcer.
4. Inducing 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, which will have a negative impact on bone mass preservation. For women, it may increase the threat of osteoporosis.
Notes on drinking coffee
1. For patients with high blood pressure, pay attention to the time of drinking coffee, try not to get up early to drink coffee, so as to avoid the sudden rise of blood pressure too high.
2. It's better to drink coffee after breakfast, because drinking it on an empty stomach may cause irritation to the intestines and stomach, which is harmful to health.
3. First smell and then taste with your tongue. When drinking coffee, don't swallow it whole, but first smell it close to your nose. If it's spicy, it means that the coffee beans are not fresh. After passing the olfactory test, take a sip of coffee in your mouth, taste it gently with your tongue, and slowly swallow it into your throat.
4. A small amount of coffee has nothing to do with pregnancy, abortion, birth defects, preterm birth and low birth rate. But for women who are already pregnant or planning to be pregnant, it's best not to consume more than 200 milligrams of caffeine a day, because a large amount of caffeine can lead to miscarriage.
