Is it bad to have coffee during meals?

In some cultures, coffee is seen as a “digestive”, but research suggests that it can interfere with the way the body absorbs certain nutrients when ingested with meals.

If you heard that having a coffee for or immediately after meals can be a bad idea, you can have a real background in this.

There are over 1,000 chemical compounds in coffee and some of them, such as caffeine, polyphenols and tannins, can interfere with the way they absorb nutrients from food.

The good news is that for most people, these effects are minimal, that is, not significant enough to cause disabilities.

Nutrients are substances present in foods and drinks that perform some vital functions in the body. We need different nutrients to keep us healthy.

“Not all absorption is completely” blocked ” – there could be only a certain reduction”, says Alex Ruani, a doctoral research researcher at the Nutrition Sciences at the University College (UCL) and Chief Scientific Educator at the Health Sciences Academy in the United Kingdom.

The impact depends on the intensity of the coffee; the amount of nutrients consumed; And individual risk factors such as age, metabolism, health and genetics, explains Ruani.

The nutrients we are talking about include football, iron and vitamins B.

It is not necessary to worry if their “levels of nutrients are already suitable, but for those who are on the verge of disabilities or low levels, the excessive intake of coffee can contribute to greater loss”, says Emily Ho, director of the Linus Pauling Institute and professor at the University of Oregon State University.

Who should be cautious with the cappuccino?

Since the 80s, studies have associated coffee with less iron absorption.

“When you have a coffee with a meal, the polyphenols present can bind to certain minerals in your digestive system,” says I have.

He explains that this link process can make it difficult to absorb iron through the body – since minerals must go through intestinal cells to enter the bloodstream. “If they remain blocked with polyphenols, they simply cross the body and are excreted.”

This is particularly important in the case of iron, in particular the type found in foods of vegetable origin, called “iron non -EME”. The iron does not emit foods such as fruit, vegetables and vegetables is more difficult to absorb from the body.

Coffee polyphenols – in particular chlorogenic acid – can bind to this type of iron, preventing them from being absorbed correctly by the bloodstream. Consequently, the iron remains attached to these compounds while it passes through the digestive system. It ends up being excreted instead of being used by the body.

All this means that people with iron deficiency anemia (Privable Iron anemia) should be cautious when coffee is expected to be very close to iron meals.

“It could be better to have a coffee at least an hour before or two after consuming iron -rich foods so that it does not mix in the stomach,” suggests Alex Ruani.

Pregnant women who are often menstruating adapt to this category of people who need to keep an eye on iron levels. In general, they need more iron and are more likely to develop iron deficiency anemia, so they should be aware of the intake of coffee.

Soccer

Football is essential for the health of the bones, but 9% of people between 16 and 49 years old in the United Kingdom consume less than the reference football of minimum nutrients (LRNI) through food. This deficit puts them at risk of having weak bones at the most advanced age.

Our kidneys remove waste and excess blood from the blood (like urine) and help to maintain the balance of chemicals (such as sodium, potassium and calcium) in the body. They also produce hormones.

Studies suggest that caffeine can hinder calcium retention by the body by interfering with the way it is developed in the kidney and absorbed in the intestine.

Once again, these effects are minimal and more significant for people who already adopt a poor football diet or who are at greater risk of health -related health problems.

“A popular study published in the scientific journal Osteoporosi International proposes that caffeine can contribute to bone loss by interfering with bone metabolism,” says Ruani. “But further studies are needed to determine the real impact of caffeine on the risk of osteoporosis.”

Football can be kept by the body, so it is not necessary to consume the recommended quantity daily, but for a period of months, adults aged 19 to 64 should eat, on average, about 700 mg of football per day.

It is also worth remembering that caffeine has a diuretic effect, IE increases the frequency with which it is necessary to urinate.

“This can lead to the loss of soluble vitamins in water (water -water, such as some B vitamins) and minerals (such as iron and calcium), since excretion plays a role in regulating their levels in the body”, adds I have.

“Due to the influence of coffee on renal function and the metabolism of nutrients, having large quantities of coffee (like four cups per day or more) can lead to an increase in ascection and therefore to the loss of vitamins soluble in water, including the vitamins of group B”, explains Ruani.

The complex vitamins B dissolve in the water, so they are not stored in the body. Instead, the excess is excreted from urine.

Probiotics

Probiotics are vivid bacteria and yeasts promoted as having different health benefits.

They can be useful to restore the natural balance of bacteria in the intestine in some cases, according to the SSN website, the British public health system, but there are few tests in support of many health accusations made on them.

However, if you want to try probiotic supplements or rich foods in probiotics, such as yogurt and kimchi, it is better to avoid consuming them with hot drinks such as coffee.

“The living bacteria of probiotics are highly sensitive to heat and exposure to high temperatures, as the coffee heat cap reduce their survival rate in the gastrointestinal tract, making them less effective,” explains Ruani.

Sometimes they are prescribed by doctors to help relieve antibiotic diarrhea. For the maximum benefit, it is advisable to wait 30 to 60 minutes before eating a probiotic if you had a cup of coffee.

Is it worth changing tea coffee?

If you are thinking of moving to tea, it is important to know that some of the same concerns also apply to tea.

“In fact, tea polyphenols can have a similar effect on the bioavailability of nutrients, so it is important to pay attention to the time of consuming tea if you are worried about the absorption of nutrients”, war is felt.
