Drinking coffee right after meals can affect the absorption of essential nutrients. According to gastroenterologist Renata Gizani, caffeine present in this drink may decrease the absorption of iron and calcium. “Coffee caffeine is responsible for reducing this absorption, especially iron and calcium,” explains the expert through the social network Instagram.
In addition, the doctor points out that caffeine consumption may be related to the reduction of vitamin D recipients. This effect may compromise the amount of this vitamins available in the body.
Another point to consider is the impact of coffee on digestion. For some people, this drink has a laxative effect, stimulating intestinal movements and accelerating food traffic through the digestive system.
According to, when food passage through the gut is very fast, the time available for nutrient absorption becomes shorter. This can lead to lower retention of vitamins and essential minerals for health.
For this reason, the expert recommends to wait some time before consuming coffee after meals. According to the doctor, this is a way to ensure better absorption of ingested nutrients.
How long after the meal can drink coffee?
“The ideal is to wait at least an hour after the meal before consuming coffee, to better absorb what we eat,” advised Renata Gizani.
For those who have a habit of drinking coffee right after lunch or dinner, it can be beneficial to adjust the routine to maximize the benefits of food. Alternatives include replacing coffee with other less stimulating drinks, such as herbal infusions or warm water, while waiting for the recommended period.
The importance of iron for the body is undeniable, as this mineral is fundamental for the production of red blood cells and the transport of oxygen in the blood. Calcium, in turn, plays an essential role in bone health and muscle contraction, and it is essential to ensure good absorption of this nutrient. Vitamin D, whose absorption can be affected by caffeine, contributes to the functioning of the immune system and the maintenance of bone health.
Effects vary from person to person
Although the effects of coffee varies from person to person, paying attention to how this drink influences nutrition can be a smart strategy for improving health. It is worth remembering that other factors can also influence nutrient absorption, such as the type of diet and the presence of compounds that interfere with digestion.
For those with iron, calcium or vitamin D deficiency, following these recommendations may be even more important to avoid long -term complications.
Thus, adopting minor adjustments to the food routine can make a big difference in the way the body takes advantage of the essential nutrients for its operation.
