Five basic knowledge about coffee boutique Coffee

Fact 1: Coffee is good for you

Coffee has both advantages and disadvantages, so moderate consumption is key to benefiting, doctors say. Drinking two to three cups of coffee a day is more than enough to protect your heart, increase metabolism and even reduce your appetite if you are overweight, according to research conducted by American biologists. Coffee contains the same amount of antioxidants as green tea, which means coffee theoretically has a cancer-preventing and age-slowing effect.

Fact 2: Coffee will kill you

Some experts say coffee should not be drunk because it can raise blood pressure and constrict blood vessel walls, so drinking too much coffee may cause heart disease.

There is some truth to this argument. However, experts in the United States believe that the lethal dose of caffeine is 10 to 13 grams, which means that you have to drink 23 liters of coffee at a time to be fatal, which is equivalent to more than 100 cups of coffee. However, drinking so much liquid at once, even if there is no caffeine, you will not be able to save your life.

Fact 3: Coffee is a good friend of fitness

Coffee has always been said differently, and many people are biased against it. This article will give you a new perspective on coffee.

Two cups of coffee a day can help relieve muscle soreness after strenuous exercise, say scientists at the University of Georgia. You don't have to drink coffee regularly, just drink two cups after exercise and you'll recover your muscles.

Another benefit of coffee is that it boosts energy, which helps you exercise longer and better. Caffeine is essential for group sports because it enhances concentration and reflexes. Drinking too much coffee, coupled with intense exercise, can lead to tachycardia and excitement, causing insomnia, nervous disorders and other symptoms.

Fact 4: Coffee is better than wine

Red wine and champagne are considered traditional drinks essential for romantic dinners. Now, however, men are rediscovering this tradition. If you want to engage passionately with a woman after dinner, offer her some coffee, suggest researchers at the University of South Wales.

In a series of experiments with female mice, they found that a certain dose of caffeine caused the mice to have more frequent sexual contact. But perhaps the drink only works for women who don't drink coffee regularly. If she drinks coffee regularly, you'll have to rely on wine and your charisma to turn her on.

There is a theory that a certain dose of caffeine will make men more active in bed. Caffeine increases blood flow, which means more blood is delivered to the sex organs, which may prolong erections and sex. Therefore, coffee can be used as a substance to prevent erectile dysfunction.

Fact 5: Coffee doesn't have much more caffeine than green tea

There are many things to say about coffee, both positive and negative. The claims that coffee helps erections and can cause insomnia are entirely true. Its main effect on the body is to stimulate the nervous system.

A cup of instant coffee usually contains as much caffeine (or slightly more) as a cup of strong black tea. Green tea may contain more caffeine.
