Is Italian coffee (Espresso) more caffeinated?

Espresso has a mellow flavor, so it is easy to mislead people into thinking that it has a high caffeine content, but in fact this is not necessarily the case.

Generally speaking, light-roasted coffee beans and coffee extracted for a long time will increase the content of caffeine. Therefore, ice drop coffee takes a long time to extract, and caffeine is higher than Italian coffee extracted under high pressure for a short time.

If you look at the caffeine label of the various coffee drinks listed by Starbucks Coffee, there is about 75 milligrams of caffeine with an Italian cappuccino, while the same medium-sized American coffee has 150 milligrams of caffeine, which is equivalent to doubling. The highest caffeine content is the daily selection coffee brewed by filter drops, which has about 240 milligrams in one medium cup.

People who drink coffee with palpitations can't touch coffee at all.

First determine if you have problems such as arrhythmia, cardiovascular disease, gastrointestinal disease, etc., and you should be instructed by your doctor to see if you can drink coffee.

Huang Shih-pi, who has run a coffee shop for many years, says that if healthy people drink coffee but have heart palpitations, they may drink coffee made from shoddy coffee beans with too much caffeine. "it is recommended to change the coffee beans to try again, or do not drink coffee brewed by the filter drop method. "

Drinking black coffee hurts your stomach?

Although most coffee lovers think that drinking black coffee can best taste the beauty of coffee, so it is not recommended to add sugar or milk to cover up the original flavor of coffee, but some people think that drinking black coffee is easy to hurt the stomach.

Hong Zhisheng, an attending physician in the gastroenterology department of Cathay Pacific Hospital, clarified that some people feel uncomfortable with their stomach and intestines after drinking coffee, mainly due to the influence of caffeine. For example, caffeine stimulates the dilator muscle at the lower end of the esophagus, making it more relaxed, which in turn causes "gastroesophageal reflux." or caffeine causes a large amount of gastric acid secretion, causing discomfort.

"the culprit is caffeine, so it has nothing to do with adding milk, while some people who drink milk have more severe symptoms," Hung said.

Therefore, people with digestive tract diseases, such as gastric ulcers, duodenal ulcers, or people who have a lot of stomach acid every time they drink coffee, should avoid coffee.

Can drinking coffee lead to osteoporosis?

Caffeine has always been considered to be one of the risk factors for osteoporosis. Caffeine has been reported to increase calcium excretion in the urine. However, from epidemiological data, it was found that moderate caffeine intake (less than 400 mg per day) was not associated with bone loss and fractures in young women aged 20 to 50. But women who are older (over 50) and postmenopausal need to drink coffee more carefully, and more than half of studies have shown that caffeine intake is associated with bone mineral density in women over 50.

How many cups of coffee do women drink a day to easily cause osteoporosis? A recent study of 3170 women with an average age of 50 to 84 found that drinking more than two units of caffeinated drinks a day (one unit equals one cup of coffee or two cups of tea) increased the risk of hip fractures by 69 per cent. Therefore, it is recommended that women over the age of 50 had better reduce their caffeine intake and should not drink more than 2 cups of coffee a day if they really want to drink coffee.

The most common companion of coffee

Some people are not used to black coffee, always add some sugar, and then sprinkle with cream balls to neutralize the bitterness of the coffee.

In fact, coffee itself is very low in calories, about 20 calories, and almost no fat, but after adding cream and cream balls, it not only increases extra calories and fat, but also is a terrible killer of cardiovascular health, "trans fat." Therefore, nutritionists strongly recommend abandoning cream and cream balls and adding low-fat milk instead, which is healthier.

People who are used to putting sugar in their coffee also have healthier choices, such as trehalose, which is relatively low in calories, or asking the store to provide you with sugar substitutes with few calories.

Coffee + dark chocolate = very French

Xie Zhongdao, a food writer who studies chocolate and publishes books, recommends coffee with dark chocolate. "the espresso brewed in Italian style is strong and strong, and paired with super bitter dark chocolate with more than 55% cocoa content, it is simply a pair of tough brothers, full of power and a long aftertaste, which is hard to recall for a long time," he said. In Paris, ordering a cup of coffee is often served with a piece of dark chocolate, which is a very Parisian style.
