Do you drink coffee with lunch or right after eating? If you have such a habit, be aware, this habit of drinking coffee hinders the process of absorbing nutrients from food in the body.

A thousand chemical compounds are found in coffee. Chemical compounds such as caffeine, polyphenols and tannins are the main ones. Yin affects the absorption process of nutrients in the body .

Although this effect is minimal in most people . The possibility of having an immediate effect on the body is less. Nutrient elements (Nutrition) are substances that are obtained from our food and drinks and are also essential for the body. We need different nutrients to stay healthy.

According to Alex Ruaney, who is a Doctoral Researcher in Nutrition Science Education at University College London and Chief Science Educator at the Health Science Academy, drinking coffee with food or shortly after eating does not completely stop the absorption process of nutrients from food in the body . But it brings some reduction . 

This effect depends on the strength of the coffee, the amount of nutrients, a person's age, metabolism, health status and genetics. He says that it affects nutrients like calcium, iron and vitamins.

Director of the Linus Poling Institute and a professor at Oregon State University's College of Health, Emily says, "If the body's nutrient levels are adequate, coffee does not seem to have any effect." But if its level in the body is low, then drinking a lot of coffee will reduce the level of nutrients even more.'

According to a study in 1980, there is a relationship between drinking coffee and reducing the absorption of iron in the body. She says, "If you drink coffee with food, the polyphenols in it can bind with some minerals in your digestive system."

This process can make it difficult for the body to absorb iron. Because the minerals in the body must pass through the intestinal cells to reach the blood. 'If these minerals are attached to polyphenols, they leave the body without reaching the blood.' This increases the risk of weakening the bones. Calcium is essential for our bones . 

Similarly, our kidneys balance chemicals (such as sodium, potassium and calcium) in the body by removing waste and excess water from our blood through urine. These elements also make our body.  According to

studies, caffeine affects the process of keeping calcium stable in the body, because it interferes with calcium processing in the kidneys and its absorption process in the intestine . Although its effect is minimal . 

A study published in the International Journal of Osteoporosis states that caffeine weakens bones. Because caffeine affects bone metabolism . But Alex Ruaney says more studies are needed to determine how caffeine affects the risk of osteoporosis.
