A recent British medical study warned against drinking coffee before eating breakfast in the morning, or on an empty stomach as many do;

But what is the reason?

The answer is that the study found that drinking coffee before breakfast impairs the metabolism, as coffee weakens the blood sugar response by 50% when consumed on an empty stomach.

The study was conducted by researchers at the University of Bath in the United Kingdom, according to a report in The Independent, and the study was published in the British Journal of Nutrition.

But by delaying drinking coffee until after breakfast, researchers found that our bodies' ability to handle food healthily has improved dramatically.

Given the importance of keeping our blood sugar levels within a safe range to reduce the risk of diseases like diabetes and heart disease, researchers believe these results could have far-reaching health effects.

The study included 29 healthy men and women, who were placed in different conditions, including sleeping normally at night, then drinking a sugary drink in the morning to assess the body's ability to control blood sugar, and sleep poorly, as the study participants were awakened for 5 minutes every hour at night, then Drink a sugary drink in the morning, sleep poorly, and then drink coffee in the morning 30 minutes before consuming a sugary drink.

The results showed that a single night of disrupted sleep did not worsen the participants' responses to blood glucose levels at breakfast compared to a normal night's sleep.

But drinking coffee before breakfast increased the blood glucose response to the subsequent diabetic drink by about 50% higher, which means that coffee negatively affected the body's ability to control blood glucose.

Professor James Bates, co-director of the Center for Nutrition, Exercise and Metabolism at the University of Bath, told The Independent, "This study is important and has far-reaching health implications ... Simply, blood sugar control is impaired when the first thing that comes into contact with our bodies is coffee. Especially after a night of interrupted sleep, and we may improve this by eating first and drinking coffee later if we feel we still need it. Knowing this can have important health benefits for all of us. "

The benefits of coffee

However, there are many benefits to coffee when consumed healthily. According to a research review published in the journal "Planta Medica", consumption of coffee may help prevent many chronic diseases, including type 2 diabetes and liver disease. .

There is also evidence that decaffeinated coffee, in some ways, has similar benefits to regular coffee, indicating that in addition to caffeine, other ingredients contribute to health-protecting effects.

For adults who consume moderate amounts of coffee (3-4 cups a day provide 300-400 mg per day of caffeine), there is little evidence of health risks, and some evidence of health benefits.

Studies have indicated that consuming more than two cups of coffee per day for patients with pre-existing liver disease is associated with a lower incidence of fibrosis, cirrhosis and cancer.

It is believed that the effects of coffee are not exclusively due to caffeine.

But it appears to be related to other specific ingredients, such as chlorogenic acid.

It is important to note that there are individual differences in responses to coffee. Some people are more sensitive to effects than others, and most people can enjoy moderate coffee consumption of up to 4 cups of coffee per day (about 400 milligrams of caffeine) as part of a healthy, balanced diet and an active lifestyle.

Excessive is harmful

Nevertheless, a consensus prevails among doctors that excessive coffee drinking has certain bad symptoms, according to a report by Deutsche Welle, citing the official page of the German Ministry of Health, that no more than 400 milligrams of caffeine should be consumed per day. The mentioned amount is equivalent to 4 cups of Italian coffee or 6 cups of Arabic coffee;

Otherwise, the body may experience many unpleasant symptoms.

Among the annoying effects of coffee are the following:

1- Diarrhea

Gastrin is a hormone that stimulates the secretion of digestive juices in the cells of the stomach, and thus stimulates stomach movement, and caffeine increases the secretion of this hormone, and automatically increases the movement of the stomach at the same time, which may lead to diarrhea.

2- Acidity

Caffeine increases the acidity of the stomach. Excessive intake of caffeine may disturb the digestive system and increase the heartburn.

3- Sweating

If you suffer from excessive sweating, it is best to reduce your coffee consumption.

4- Frequent urination

Caffeine activates the mechanism of urination, and this leads to the need to urinate at a higher level;

So if you have a long way to travel, it is best not to drink too much coffee.
