What are the benefits of women drinking coffee?
Coffee has a long history. After hundreds of years of development, it has more than ten kinds of coffee and become a popular drink all over the world. Among them, cappuccino, latte and other kinds of coffee are deeply loved by female friends, creating world-famous coffee shops such as Starbucks and Lorenzo, which have become an important part of urban fashion elements. Coffee also has many functions, but the reason why many fashionable women drink coffee is to refresh their minds. In the face of high-intensity work pressure and living environment, this is an additive to keep energetic. I saw a news occasionally the other day, which was really surprising. According to the latest findings of Swedish scientists, if women drink more than three cups of coffee every day, their * * * will become smaller.
Cancer researchers found through tests that half of women contain a special gene, because when they ingest caffeine, this gene will shrink. The study tested nearly 300 women, but Helena Kinslow of Lund University said that women don't have to be on tenterhooks all day. "Women who drink coffee don't have to worry that their * * * will get smaller overnight," she explained. * * * Although it will get smaller, it will not disappear completely. If someone wants to judge who drinks coffee according to the size of a woman's bra, they will be disappointed in the end. Bras have two sizes, one is the size of the cup, and the other is the circumference of the bra, so it is difficult for you to tell which women drink coffee from the bra. "Although caffeine may make women's * * * shrink, men who drink coffee will have the opposite result, and their * * * * will increase. The study also found that caffeine also has a beneficial side, which helps to reduce the risk of breast cancer in women.
This news is almost equivalent to putting a blockbuster in the women's group. Due to the genetic differences and eating habits between the East and the West, not every oriental woman can have a proud chest. As a woman, the love of beauty is innate. Full breasts are an indispensable part of female beauty and are the dream of many women. How can a daily diet product destroy their pursuit of beauty? However, the habit of drinking coffee has penetrated into the life of urban women, just like the influence of alcohol and tobacco on men, which cannot be easily broken. As the saying goes, you can't have your cake and eat it. How to choose is really embarrassing.
Specific how to choose, to analyze the pros and cons of drinking coffee.
The benefits of drinking coffee:
A, coffee contains certain nutrients, such as vitamin B, free fatty acids, caffeine, tannic acid and so on.
B, coffee can promote metabolic function and digestive organs, which has a great effect on constipation. Cutting off the source of accumulated toxins in the body will inevitably reduce the chances of spots and acne reduction. This reason must be popular with women.
C, coffee has the effect of hangover, which can quickly oxidize acetaldehyde converted by ethanol, decompose it into water and carbon dioxide and excrete it.
D, coffee can prevent gallstones. Because caffeine can shrink the gallbladder and reduce cholesterol which is easy to form gallstones in bile, researchers at Harvard University recently found that people who drink coffee every day have a lower risk of gallstones than 40%.
Drinking coffee often can prevent radiation damage. This is a reason for working women who often sit in front of the computer and drink coffee.
F, coffee has antioxidant and anti-aging effects. With this advantage, I believe many women are even more reluctant to give up the habit of drinking coffee.
Then look at the disadvantages of drinking coffee. Here, I only talk about three points about people's health.
First, aggravate high blood pressure. Caffeine itself has analgesic effect, which can raise blood pressure. If you add emotional tension, it will produce very dangerous results.
Second, induce osteoporosis. Caffeine itself has a good diuretic effect. If you spend a lot of time drinking coffee, it will easily lead to bone loss. For postmenopausal women, calcium loss caused by estrogen deficiency, coupled with a large amount of caffeine, may pose a threat to the human body.
Third, as mentioned above, it will lead to smaller breasts of women.
In fact, the two most important things are to master the amount of coffee and the time to drink coffee. You can drink some coffee every day, but it is best not to exceed two cups. Swedish researchers also made it clear that more than three cups a day will make your breasts smaller, so you don't have to worry about it within this range. It is best to drink coffee after lunch every morning and avoid drinking coffee after meals, because coffee can promote gastrointestinal peristalsis and help digestion, but drinking coffee after meals may make people too excited and affect sleep. Compared with these, it is not difficult to make a choice. As long as you drink coffee regularly and moderately, you can avoid some unfavorable factors while understanding the unfavorable factors of coffee and taking preventive and remedial measures.
The advantages and disadvantages of drinking coffee? Can I have a drink at noon and in the evening?
The benefits of drinking coffee:
1. Coffee contains some nutrients. Nicotinic acid in coffee contains vitamin B, and roasted coffee beans have higher content. But also free fatty acids, caffeine, tannic acid and so on.
2. Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs and play a great role in constipation. Bathing with coffee powder is a kind of hyperthermia, which has the function of losing weight.
3. Coffee has the function of relieving alcoholism. Drinking coffee after drinking will quickly oxidize acetaldehyde converted by alcohol, decompose it into water and carbon dioxide and excrete it.
4. Coffee can relieve fatigue. To eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.
Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it can shrink gallbladder and reduce cholesterol which is easy to form gallstones in bile. Recently, researchers at Harvard University found that men who drink two or three cups of coffee a day have a lower risk of gallstones than 40%.
6. Drinking coffee regularly can prevent radiation injury. Radiation hazards, especially electrical radiation, have become the prominent pollution at present. Baba's Indian atomic researchers reached this conclusion in mouse experiments and said it can be applied to humans.
7. The health function of coffee. Coffee has the functions of resisting oxidation, protecting the heart, strengthening bones and muscles, benefiting the waist and knees, stimulating appetite, promoting eating, reducing fat and digestion, inducing resuscitation and removing dampness, promoting blood circulation and removing blood stasis, calming wind and relieving spasm.
8. The influence of coffee on mood. Experiments show that the average person absorbs 300 mg (about 3 cups of brewed coffee) every day, which will have a good influence on a person's alertness and mood.
Disadvantages of drinking coffee: Excessive use has many disadvantages.
In the case of long-term intake, large doses of caffeine are drugs, which will lead to "caffeine poisoning". Caffeine poisoning includes addiction and a series of physical and psychological adverse reactions, such as nervousness, irritability, anxiety, tremor, muscle twitching (hyperreflexia), insomnia and palpitation (most people take caffeine because of its * * * effect, and many students take caffeine tablets when preparing for exams and working at night. Under the strict definition of addiction, addiction is only when the dose is gradually increased. Caffeine dependence is more appropriate, but under a widely accepted definition, all chronic behaviors that are difficult to get rid of are called addiction, so it can also be described as caffeine addiction. In addition, because caffeine can increase gastric acid, continuous high-dose intake will lead to peptic ulcer, erosive esophagitis and gastroesophageal reflux disease. However, because both regular coffee and decaffeinated coffee will affect gastric mucosa and increase gastric acid secretion, caffeine may not be the only component of coffee.
The benefits of drinking coffee?
It can refresh you.
But with the increase of caffeine and alcohol content, it is always 8. All right. .
==================
Caffeine has the function of central nervous system and muscle, so it can cheer up 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 lose weight. In fact, this is only one of the factors. Caffeine can really accelerate the decomposition of fat, but at the same time, it needs to rely on muscle movement 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 exercise actively at the same time in order to have 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.
antioxidation
If all the foods popular in the market are foods with antioxidant function, generally known vegetables and fruits are rich in vitamins A, C and B. Tea, which is quite popular in Japan, is regarded as healthy food because it is 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 the content of antioxidants in coffee is four times that of tea, and it has stronger resistance to cardiovascular diseases. Moreover, coffee itself conforms to the principle of antioxidants, with darker color and bitter taste. Each coffee contains different antioxidants because of different brewing methods. For example, American coffee contains the least antioxidants, while espresso contains the most antioxidants. After adding creamer to coffee, its antioxidant effect will not be affected.
Improve dry eye
Foreign reports point out that people who drink coffee are much less likely to suffer from dry eye than those who don't drink coffee. This is mainly related to the purine component in coffee (eye drops containing purine can make glands 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 drugs containing diuretic ingredients must be forbidden to take caffeinated drinks so as not to aggravate the loss of water in their bodies.
It can relieve pain.
Headache caused by a bad night's sleep or pain caused by vasoconstriction on one side of the temple can be relieved by coffee, but it must be drunk in the morning or at noon (note: it is forbidden from afternoon to night).
