You drink coffee, but do you know anything about coffee?

"I'm not at the cafe. I'm on my way to the cafe." These two famous quotes aroused people's imagination about the literary flavor given by coffee in the mid-1990s. At that time, to drink a cup of freshly brewed coffee, unlike it is now available everywhere, Xingxue has not yet been introduced to Taiwan, and most of the coffee sold in supermarkets is still instant products. If you want to have a good cup of coffee, in addition to trying to find utensils to brew it yourself, it is best to have a private cafe that you often run to relieve your gluttonous addiction, either digging a treasure coffee "waiter" from a cool shopkeeper, begging him to teach you how to make coffee, or simply quietly nesting in a corner of the "pilgrimage".

The coffee craze is exploding.

Once upon a time, the smell of coffee crept in people's hearts, and two or three convenience stores at the corner of their homes could provide freshly brewed coffee at any time. About two or three years ago, several super-merchants set their sights on the cooked food market, launched their own coffee brands one after another, touted grinding and fresh cooking, adopted a low-price strategy or merged with other fresh food offers, in an attempt to attract the attention of consumers. to compete for the market cakes of the chain coffee shops, and recently invited popular idol stars to endorse, a "coffee war" lively debut!

As a result of fighting, consumers are happy to pick bargains, the number of coffee drinkers is also on the rise, the coffee boom continues to burn, and even local counties and cities have held coffee festivals one after another to vote for popular coffee shops. Whether you drink individual coffee or Italian fancy coffee, "drinking coffee" has become a national movement, both fashionable but with a touch of nostalgia. Unwittingly, a cup of coffee in hand has become part of the city's street view, and the daily life of the island seems to be inextricably linked with coffee.

Drink coffee bags to lose weight? What a beautiful idea!

However, before we can "crazy" coffee, we need to understand the health aspects of drinking coffee. Some people say that drinking coffee has many benefits, while others think that excessive drinking is harmful to the health. Online people have different opinions, and there are a lot of specious myths and legends.

Chen Yuyin, head of the nutrition team at Xindian Gengfu Hospital, explains that the benefits of drinking coffee to the human body, first of all, is refreshing, because caffeine can stimulate the body's central and sympathetic nerves and boost the spirit. In addition, some studies have found that caffeine can affect the secretion of sympathetic nerves, hormones and hormones, which can slightly increase the body's basal metabolic rate and further accelerate the decomposition of fat, so many people regard "drinking coffee" as one of the means of weight loss. However, accelerating fat decomposition will not consume fat. If there is no matching exercise, fat will still gather from the blood and return to the body to continue hoarding, so simply drinking coffee has no weight loss effect. You have to rely on continuous exercise to drink coffee in order to achieve the effect of weight loss and multiplication. Here, I would also like to remind readers that "drinking coffee" here refers to black coffee with no cream or powdered sugar. Cream and sugar are the most wanted calorie criminals!

Drinking coffee is good or bad, it varies from person to person

Some studies have analyzed the composition of coffee and found that coffee has four times more antioxidant effects than tea. Chen Yuyin said that the functions of general antioxidants include whitening, anti-aging, wound healing, and so on. however, there is no further research data to prove that drinking coffee has the equivalent effects of whitening and anti-aging. It is worth noting that antioxidant capacity can prevent some cardiovascular diseases, but long-term drinking coffee can also lead to a rise in blood pressure and hardening of blood vessels, which makes drinking coffee a question mark on cardiovascular protection.

Chen Yuyin pointed out that external studies have reported that the purine substance contained in coffee can stimulate the secretion of eyeball glands, which can relieve some dry eye symptoms for people who use computers for a long time. At the same time, drinking coffee can also relieve some mild nerve pain (such as migraines). In addition, coffee can stimulate the peristalsis of the gastrointestinal tract, for people with constipation can promote defecation, but some people will cause abdominal distension, diarrhea, or depends on personal condition and physique; especially if you are used to drinking coffee, I am afraid the effect of stimulating the intestines is not so great.

One cup or two cups a day is perfect.

How many cups of coffee can a person drink a day? Chen Yuyin said that drinking about 1 cup or 2 cups a day is a more appropriate amount. If you drink too much, you may have the symptoms of mild caffeine poisoning (it is easy to consume 500-1000 mg a day), restlessness, anxiety, palpitations, diarrhea, and in severe cases, it may also cause convulsions, hypokalemia, arrhythmia, and even the risk of heart paralysis.

Chen Yuyin also cautioned that drinking coffee is easy to increase the loss of calcium, iron and vitamin B, so do not drink coffee immediately after a meal, preferably 2 hours later, so as to avoid interaction with food. inhibit the absorption of nutrients during meals (there are habits of taking medicine and drinking at intervals).

Moreover, when drinking, it is best not to add sugar and cream, it is better to simply drink black coffee, if you really like the taste of milk, you can add some milk powder or fresh milk, do not add cream; cream belongs to trans fatty acids that are harmful to the human body. it does great harm to the cardiovascular system in the long run.
