How to drink coffee correctly?
1. Drink in moderation, do not be greedy for cups
Healthy adults should not exceed 3 cups per day and consume no more than 250 mg of caffeine.
Because drinking a lot of coffee can cause tachycardia and other discomfort, increase the burden on the heart, and it is likely to seriously affect sleep at night.
2. Coffee must not be drunk on an empty stomach
Coffee is best drunk after breakfast at 9 a.m., before 9 a.m. is the peak period of human adrenaline and glucocorticoid secretion.
It is not recommended to drink at night, it is likely to affect normal sleep.
It should not be drunk on an empty stomach, which will stimulate the stomach to secrete excessive gastric acid, causing acid reflux, stomach pain and other symptoms. Drinking coffee at temperatures above 65°C can damage the esophageal mucosa and increase the risk of esophageal cancer.
3. Choose pure coffee to drink
Drinking coffee can add a small amount of milk, but it is best not to add creamer, sugar, etc., which is easy to increase the risk of obesity, dental caries, diabetes and so on.
It is recommended to drink less instant coffee because it contains more sugars and trans fatty acid vegetable fat.
Although the coffee is good, don't be greedy for a cup~ drink it in moderation according to your physical condition! I hope that everyone can drink coffee scientifically and get the health benefits of drinking coffee.
