There are those who cannot live without their coffee first thing in the morningHowever, others prefer drink it right after food. This stimulant drink It is one of the most popular in Spain, so it is not unusual to see restaurants offer a cup after meals. In this context, some questions arise about the effect it can have on digestion. The truth is that can have both benefits and drawbackswhich is why its influence on the body is a dichotomy that experts have wanted to study over the years.
One of the most widespread beliefs is that coffee is a digestive that helps intestinal transit. The scientific basis for this is the fact that coffee stimulates the production of gastric acid and the motility of the digestive tract, which could speed up digestion. Nevertheless, This can also have a big disadvantage in people who have problems like gastroesophageal reflux or gastritis, since excess gastric acid can aggravate its symptoms.
The effect of coffee on nutrient absorption
One of the aspects that studies collect about drinking coffee after a meal is the impact it has on nutrient absorption. Above all, the concern is due to the inhibition of two essential minerals for the body, such as calcium and iron.
drink coffee after a meal rich in red meat, legumes or vegetables that provide non-heme iron, it is almost like not ingesting them. This has the consequence that people suffering from anemia or low levels of iron may not be acquiring the necessary nutrients. That is why experts recommend Wait at least an hour to drink coffee after eating.
In the case of calciumits decrease has not so much to do with absorption but rather with elimination. drink coffee after meals rich in this mineral will cause the coffee to minimally interfere with absorption in the intestine, but it will increases calcium levels that are eliminated by the kidneys. This causes it to be decreased at general levels in the body.
Its impact on metabolism and the weight myth
Coffee is known for its ability to stimulate the central nervous systemincreasing alertness and energy levels. Is this need for stimulation and productivity after the drowsiness caused by meals that makes us ingest it. However, Not all of us are affected equally.
While some people experience a increase in their ability to concentrate and stay active, others may feel nervous or anxious. Experts therefore recommend moderate consumption and even avoid it if you are sensitive to caffeine.
On the other hand, there is a theory that coffee helps you lose weight if you drink it after meals. Although its caffeine content can increase metabolism and calorie burning, weight loss is minimal. A myth that has just collapsed regarding the addition of sugars or sweeteners to coffee.
