Drinking Green Tea on an Empty Stomach
Personally, I don't take green tea first thing in the morning or on an empty stomach. Why?
!. Green tea is has lots of tannins which can increase acidity in the stomach which can lead to stomach pain, nausea, constipation, and vomiting.
2. Another reason is that green tea contains caffeine, though not as much as coffee and not as much as the black tea. The adverse effects of caffeine can be greater on an empty stomach which can cause sleepless nights.
3 And lastly, green tea has catechins which lowers the body's ability to absorb iron. So if you are anaemic, you should't drink green tea, especially on an empty stomach.
However, for those who use green tea in losing weight, it's best to consume it on an empty stomach as long as you are not suffering from hyperacidity, anaemia, and anxiety.
