Does black coffee hurt your stomach in the end? The answer is "it doesn't hurt the stomach." where does the saying that coffee hurts the stomach come from?

Everyone says that caffeine hurts the stomach, caffeine does stimulate the secretion of gastric acid, but the amount of gastric acid secretion is related to the instantaneous concentration of drinking. Tea that Chinese people like to drink also has a lot of caffeine, so why doesn't drinking tea hurt the stomach? The way to drink tea is to soak one bubble at a time, each time is relatively short, caffeine is extracted from each pot of tea, and the concentration of caffeine in the stomach is not as high as that of coffee. So tea has the illusion that it doesn't hurt the stomach.

In fact, there is a substance called Chlorogenic Acid (CGA) in coffee, which accounts for about 60.7% of Arabica species and more than 10% of Robbosa species. Half of CGA will be broken down when roasted over medium heat, and 80% of CGA will be broken down in French roast. The decomposition of CGA will increase the amount of caffeine and quinic acid. It has been pointed out in the literature that the CGA of about 200mg will increase stomach secretion, and the CGA content of a cup of coffee varies from about 15-325mg. Therefore, in addition to baking, it is brewing. It will be discussed by two problem points.

Roasting, usually the average person has not been able to determine the baking degree, if you can drink a little sour coffee, that is, shallow roasted coffee, his CGA will be broken down less. If you have to drink someone with a sweet taste in bitterness, you should pay attention to the way you cook it!

The factors that affect the solubility of caffeine are as follows (caffeine is easy to dissolve in hot water and not easy to tolerate cold water)

1. The higher the temperature, the more extraction.

two。 Stirring or not, stirring can increase the dissolution rate and the extraction rate.

3. Pressure, high pressure cooking (ESPRESSO) will also increase the dissolution rate.

4. Soaking time, coffee powder soaking time in hot water, the longer the caffeine dissolves!

5. The amount of water brewed, the so-called strong refers to the consistency of the coffee, not bitter or not bitter! Viscosity if the taste of milk as 10 points, boiled water 1 point, divided into 10 equal points, to distinguish the difference. The stronger the caffeine, the higher the caffeine content per ml!

Usually siphon is relatively high caffeine concentration, because stirring, soaking time is longer, ESPRESSO because of pressure cooking, but the time is short, so the caffeine content is not higher than siphon, what about hand flushing? The temperature is low, and the brewing time is similar to siphon, but without stirring, his caffeine concentration should be similar to that of ESPRESSO, but why do some people say that after drinking ESPRESSO, they will be dizzy? for the same reason as drinking tea above, the concentration of caffeine in the stomach is too high in an instant, so there will be an obvious reaction. Would you feel that way if the same cup of Espresso was added to milk to make lattes or cabs?

Will drinking black coffee hurt your stomach after all?

If it hurts your stomach, whether you drink black coffee or coffee with milk, the result will be the same!

The point is that if people with a bad stomach, eat a little food at the bottom before drinking coffee, this is the right way.
