So how does coffee aid digestion?

Coffee stimulates gastric, bile and pancreatic secretions. Researches have demonstrated that the consumption of coffee increase the secretion of gastrin hormone by the stomach wall. During this process the production of gastric acid is also triggered.

What is interesting is that the amount of gastric acid produced depend on how much the coffee have been roasted. It has been noted that dark roasted coffee is less effective in stimulating the production of gastric acid. This mainly because the coffee beans lose some of its compound during the roasting process.

This is the process whereby muscle contraction make the food move along the digestive tract. Hence, coffee does aid digestion and sometimes it can also accelerate the excretion process.

A cup of espresso for sure will help for a better digestion, but it should not be considered as the super remedy to alleviate your stomach if you are having digestion troubles. You have to take some factors in consideration when having a cup of coffee after your meal; the quantity and kind of food you ate (for e.g acidic) if you consumed alcohol and also the intensity of the coffee. Too much of alcohol, acidic food and strong coffee make a bad cocktail that can cause heartburn.

On the other side when you ate a very little amount of food but have excessive coffee just after, it can cause undesired effects like diarrhea.

Therefore, the best coffee that help agreeable digestion will come beans that have been roasted at an optimum degree. They will neither be excessively nor not enough acidic, this attribute can be found in French and Italian roast.

Moreover, when buying your coffee, try to choose beans produced in countries like Brazil, Peru, Guatemala, Sumatra and Indonesia. The are countries with lower altitudes and beans grown there have a low level of acidity. You can also look for coffee beans which have ‘low acid’ label.

The best time and what coffee to drink

There is a part of the human brain which is called suprachiasmatic nucleus that control the cortisol level in our body. When secreted, this substance make us become more alert and reactive ( just like caffeine does).

Therefore, drinking coffee during these time when your cortisol level is high will add up additional stress on your body. The good news is that cortisol its at its low level during the afternoon. Hence, if you are having your lunch at around 12 -2pm there is no likely risk that it happens.

If it happens that you have a high level of cortisol, then a half decaffeinated coffee will be more appropriate and less chance to give side effects like heartburn. An interesting fact is that most people like to have espresso after lunch, this is because it is almost calorie-free and in small quantity.

However, if you have an Affogato (ice cream coffee) instead, chances of a smooth digestion are very low!
