Green tea has been termed as one of the safest and healthiest beverages to consume. It contains antioxidants that have the potential to fight various diseases like cancer, heart disease, and obesity.
However, there are still a few things to keep in mind when drinking green tea. Due to the positive spotlight, green tea has enjoyed, some green tea side effects are often overlooked.
These side effects need to be avoided by controlling the amount of green tea consumed. Today’s article will show you some of the side effects of excessive green tea intake.
Check them below:
1. Upsets the stomach
The tannins present in the green tea increases stomach acid which may cause stomach ache, nauseous feeling, or cause constipation. Thus, green tea is not consumed on an empty stomach. It is best to drink green tea after a meal or in-between meals. Studies have proven that tea is a potent stimulant of gastric acid, which can be reduced by adding milk and sugar. People with peptic ulcers or acid reflux should not overconsume green tea.
2. May cause birth defects
According to several studies, drinking excess green tea during pregnancy may have a negative impact on the mother and the unborn. Consuming more than 300 mg of caffeine per day increases the risk of hypertension during pregnancy. Scientists discovered that caffeine and tannins in green tea can reduce the levels of folic acid. However, folic acid is a water-soluble B-vitamin that prevents miscarriages and birth defects like spina bifida.
3. Reduces the iron content in the body
Green tea contains catechins that are known to boost metabolism and help reduce weight; however, its excessive consumption can cause reduced iron absorption in the body. It can be worse for those who already have an iron deficiency. You can reduce this effect by squeezing some lemon into the tea.
4. Constant headaches
Green tea can cause headaches in certain individuals since it contains caffeine. People who suffer from migraines can consume green tea occasionally. However, you should avoid drinking green tea every day if you suffer from daily headaches. If you have caffeine sensitivity, it’s advisable to avoid green tea.
5. Influences insomnia
Green tea contains only small amounts of caffeine, but may still cause problems sleeping for people sensitive to caffeine. The caffeine present in green tea is a nervous system stimulant. Consuming more than 300 mg of caffeine per day may reduce sleep quality and cause insomnia, irritability, depression, anger, and anxiety. When you have a large amount of green tea in your body system, getting good sleep will be almost impossible.
