3 times you should absolutely not drink coffee
When you are hungry
Coffee is naturally acidic, and drinking it on an empty stomach can irritate stomach acid, causing heartburn and nausea. This also reduces the pressure of the lower esophageal sphincter, causing acid to reflux from the stomach. Common symptoms include heartburn, burning in the chest, nausea or vomiting.
Coffee contains many compounds that can stimulate intestinal motility, including caffeine and chlorogenic acid. They promote regular bowel movements and reduce constipation when combined with a balanced diet. However, drinking coffee on an empty stomach causes intestinal motility to increase rapidly, leading to digestive symptoms such as diarrhea.
If you regularly drink coffee on an empty stomach over time, this condition increases the risk of diabetes. Everyone should have some light food before drinking coffee for better health.
When going to bed
Coffee contains a lot of caffeine, which affects the nervous system. It blocks adenosine receptors (one of the receptors that makes the body sleepy when awake), which affects and disrupts the day-night biological rhythm. Drinking coffee close to bedtime can easily disrupt the sleep cycle, making it difficult to fall asleep deeply.
According to nutrition experts, the recommended daily safe caffeine intake is no more than 400 mg, and should be taken 6 hours before going to bed at night.
While pregnant
Healthy pregnant women can also drink coffee, but in appropriate recommended amounts. The recommended amount of caffeine for women who are pregnant or planning to become pregnant is about 200 mg or less. Depending on the type of coffee and the method of preparation, this is equivalent to 1-2 cups. However, it is best for pregnant women to consult their doctor before drinking coffee.
The best time to drink coffee is after breakfast, early afternoon. Some foods that can combine and reduce the side effects of coffee include whole grains, nut butters, and fruits.
