Coffee

When talkin about coffee, the emphasis is placed on the content and effect of the caffeine. Caffeine accelerates breath, increases coronary flow and increases the production of stomach acid, which can affect gastric problems. Caffeine accelerates the effect of certain substances that come into the body - such as aspirin. Effects of caffeine can be observed up to 6 hours after ingestion.    

Caffeine in greater extent may also be dangerous. The lethal dose of caffeine is about 100 to 150 milligrams per one kilogram of coffee. The information which may be not well known is, that quality coffee actually contains less caffeine.

Women (especially in her forties), according to Chinese medicine should be careful with coffee. The negative effect of coffee on the connection between the heart and the kidneys leads by Chinese medicine to stagnation and accumulation of mucus in the chest and genitals.

The debunked myth about coffee    

Did you know that the water in good cafes is served to coffee only to clean the customer taste buds? 

In the recent decades,hundreds of scientists examined coffee in numerous studies. In principle, the normal coffee consumption (no more than 4 cups a day), does not drain wather from the body.

Coffee - Stimulant of the sports performance

After drinking a cup of coffee, the endurance of the aerobic activities improves. Contained caffeine delays fatigue and increases the activity of the heart and thus the heart rate.
Caffeine can have the effect not only the endurance, but also during the strength exercises is described the effect, when the substances contained in coffee help to release fatty acids into the blood and thereby save the muscle glycogen.
That would mean more opportunities to practice with unchanged intensity and subsequently bring better results in building muscle mass. People who don't drink coffee very often will respond better to these advantages than people who consume this drink regularly in large quantities.

Fat Burner

If you prepare your coffee with sugar and milk, you would probably not burn a lot of fat, the use of various coffee products with sweet flavors or cappuccino is totally inappropriate. Naturally, it is appropriate to combine the effects of caffeine with other burners like for example carnitine.

Pros and Cons    

Coffee is produced by roasting. And as known, by roasting arises the carcinogenic substances. Further, when there appears any defective material, coffee seed canbecome rancid, and then that's not good for health too. Better is the filtered coffee, because it does not irritate the stomach as much as for example the classic Turkish coffee.

Other studies, on the other hand claims, that coffee protects against certain cancers, increases metabolism and prevents circulatory diseases, of course, in case of reasonable consumption.

The great coffee faux pas a.k.a. "piccolo" does not exist!

We are witnessing the wrong names of coffee expressions as piccolo or espresso for a very long time. Mostly, waiters are surprised in cafes by the orders such as- small espresso, or even a larger piccolo ...    

If a guest orders an espresso, a waiter should bring an espresso. Coffee foodies, bartenders, waiters - nothing like an espresso or piccolo exists!
Of course now as a waiter, you can say: And now what...I'll learn all the right names and a customer comes along, orders an espresso, I would bring the proper espresso, but the customer is dissatisfied, because the costumer meant actually something else.
Yes, such situation is certainly common, but we need  to start somewhere gradually with a "reinstallation" coffee culture in your country, but also anywhere in the world.
