But today I want to expose a fact,
The above effects are not only related to caffeine.
For example, common cola and some functional drinks also contain caffeine.
But it doesn't seem to have achieved a "smooth" effect.
post-truth era,
Only by knowing oneself and knowing oneself and knowing oneself and knowing oneself and one who "eats and drinks" can not be defeated in a hundred battles,
What exactly is the physiological mechanism of coffee promoting bowel movements?
Break the "caffeine" filter
| The reason why coffee promotes bowel movements doesn't depend entirely on the caffeine that stimulates the sympathetic nervous system. |
- An animal experiment in the United States showed that even after caffeine was removed, coffee still promoted intestinal peristalsis and changed the intestinal flora, suggesting that other components in coffee may also be involved in this process.
When coffee reaches the stomach, it sends a message to the brain to stimulate the colon, which in turn produces gastrin (a peptide hormone that promotes stomach acid secretion) and cholecystokinin. At the same time, the "humoral hormones" or "nerve rates" in coffee promote the secretion of gastric acid, phlorin and other substances, causing the colon to contract muscles for a while, thus producing a "bowel movement".
- In addition, some components in coffee, such as chlorogenic acid and N-alkyl-5-hydroxytryptamine, have also been found to increase the level of stomach acid, stimulate the production of more stomach acid, and help break down proteins, thereby promoting gastrointestinal peristalsis and digestion of food. Compounds with antioxidant and anti-inflammatory properties may also have an effect on the gut. These ingredients may stimulate intestinal activity, which promotes bowel movements.
The convenience of hot and cold coffee
| In comparison, hot coffee is more convenient than cold coffee. |
Secondly, hot coffee stimulates the body's digestive system and initiates intestinal peristalsis, thereby aiding bowel movements. According to research, hot coffee can trigger intestinal peristalsis 60% stronger than hot boiled water, and 23% stronger than decaffeited coffee, which is the result of an unknown ingredient in coffee promoting gastrin secretion in the stomach and accelerating sigmoid peristalsis. Most people feel the urge to poop within 20 minutes of drinking hot coffee.
Four situations don't crave coffee
Fasting state:
Caffeine stimulates gastric acid secretion, which can easily affect the digestion and absorption of gastrointestinal function in an empty state, which may induce gastric ulcers and diarrhea in the long term; |
Drinking excessively:
Coffee has the effect of stimulating bowel movement for most people, drinking too much will overstimulate the stomach and intestines, aggravate the urge to defecate, and may lead to diarrhea and diarrhea; |
Poor Gastrointestinal Diet:
Coffee has the effect of stimulating gastric acid secretion, and after drinking coffee in the stomach, it stimulates the gastric mucosa and promotes gastric acid secretion, which may induce gastrointestinal diseases and cause diarrhea; |
Intestinal allergies:
Allergies are not only itchy skin, some people do not have skin damage, but manifest symptoms such as abdominal pain and diarrhea. |
Coffee doesn't cure a little constipation
| Coffee heads should be cautious - don't rely on coffee for a long time to defecate, and should consume more dietary fiber every day! |
Diminishing marginal utility:
Although coffee can promote bowel movements, excessive consumption can cause food to stay in the intestines longer, which can reduce water absorption and may lead to constipation. In addition, long-term reliance on coffee to stimulate the intestines is easy to make the intestines gradually paralyzed by gastrointestinal motility, and intestinal peristalsis will become more and more "lazy", which will lead to the situation that you can't defecate without drinking coffee in the long run.
| In addition, in addition to promoting gastrin secretion, coffee itself also contains tannic acid and other ingredients, which will aggravate constipation! |
