A nutritionist talked about the consequences of drinking coffee on an empty stomach. According to her statement, the drink has a lot of useful properties, but it is important to pay attention to its harm when drinking incorrectly.

Coffee affects sugar indicators

Black coffee can increase blood sugar by 10-25%. The drink has a glycemic index of about 60. Thus, insulin can rise. A person's health depends on its indicators.

Caffeine increases appetite

Coffee can increase the secretion of gastric juice, for this reason, consuming caffeine on an empty stomach provokes gastritis and peptic ulcer disease, the doctor said. The risk of heartburn and irritable bowel syndrome may also increase. If you choose breakfast with a drink, you can reduce acidity.

Coffee provokes reflux

Coffee can relax the lower esophageal sphincter. Due to this, the valve closes completely, and stomach acid leaks into the esophagus, leading to acid reflux. With long-term chronic acid reflux, esophagitis, an inflammation of the esophagus that leads to cancer, can occur. If a person has esophagitis, gastritis, duodenitis, it is better to drink coffee with milk/cream. In this case, milk casein and fats block the action of acids, the doctor noted.

Coffee washes out calcium

As a result, osteoporosis occurs. Scientists conducted research for 6 years. 85 thousand women took part in it. They found a relationship between the consumption of caffeinated beverages and increased bone fragility.

Coffee washes out vitamin B1

Vitamin B1 (thiamine) deficiency leads to that a person's psycho-emotional state is constantly changing, resulting in irritability and fatigue, problems with memory and concentration.

Coffee impairs iron absorption

When drinking coffee, the assimilation of iron slows down by 39%, tea by 64%. If you drink freshly ground coffee, absorption of the trace element decreases by 72-91%, the doctor added.

Coffee increases adrenaline levels

Caffeine temporarily “invigorates”, leading to fatigue and depression. Cortisol can increase, increasing the heart rate and blood pressure.

When quitting smoking – a cup of coffee in three

Smoking can increase the metabolism of caffeine. Thus, caffeine has less effect on smokers. If you quit smoking, the rate of caffeine neutralization decreases by 36%. As a result, its concentration in the blood increases by 200%, the specialist explained.

The best time to drink coffee

To enjoy a cup of aromatic coffee, it is better to choose late morning, after breakfast. If you do this before breakfast, your blood sugar will rise, you will experience heartburn, acid reflux and nervousness. It is better not to drink coffee immediately after waking up because of the high level of cortisol, which peaks at 7 o'clock in the morning.
