The right way to lose weight and drink black coffee:

If drinking black coffee is to promote metabolism, you should indeed drink black coffee on an empty stomach or before exercise. If you drink black coffee on an empty stomach, the caffeine absorption effect is better, and if you drink again with exercise before exercise, you can accelerate your metabolism, but there are diseases such as gastritis, gastric ulcer, gastroesophageal reflux, or cardiovascular disease. Avoid drinking black coffee before meals and before exercise. (

Does black coffee hurt your stomach in the end? This is what my colleague Xiaoyu asked me. If you ask my coffee worms, the answer is'do not hurt your stomach', where does the saying that coffee hurts your 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 6% of the Arabica species and more than 10% of the robusta species. Half of the CGA will be broken down when roasted over medium heat, and 80% of the CGA will be broken down in French roast. The decomposition of CGA will increase the amount of caffeine and quinic acid. It is 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, so purring, in addition to baking, is a way of 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 something bitter with a sweet taste, you have to pay attention to the way you cook it!

I don't have the exact data to tell you which brewing method has the highest caffeine. The way he analyzes it is the extraction rate (solubility, the extent to which caffeine is dissolved in hot water), so you have to talk about a little chemistry! It won't be too chemical, be patient and have a look!

The factors that affect the solubility of caffeine are as follows (caffeine is easily soluble 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, the question of whether it is bitter or not has been written in the previous article on the coffee flavor trip! Viscosity if the taste of fresh milk as 10 points, boiled water 1 point, divided into 10 equal points, to distinguish the difference. The thicker it is, of course per C.C. The higher the caffeine content will be!

Usually the race wind (red suction type) is a relatively high caffeine concentration, the former because of stirring, soaking time is longer, ESPRESSO although because of pressure cooking, but the time is short, so the caffeine content is not back to the competition wind is high, then hand flush? The temperature is low, and the cooking time is similar to that of the race wind, 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 the above tea? 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.
