Green tea is believed to be effective in everything from weight loss to strengthening the immune system. Many studies have shown that if green tea is used properly, it can have many benefits for the body. But there are also some disadvantages of drinking it which you may not know about. So let us know about its disadvantages today.
drinking green tea on an empty stomach Stomach problems may occur Because it can cause stomach irritation. Because green tea contains tannins which can increase the level of acid in the stomach. This can make you feel constipated, acid reflux and vomiting. If you drink very hot green tea, then these problems are more likely to occur. Drinking too much green tea can also cause diarrhea. The caffeine present in it has a laxative effect on the colonic muscles, causing frequent movements. Due to which you may have to go to the bathroom frequently. If you already have stomach problems, then you should not drink it. To avoid this, do not drink green tea on an empty stomach. You can drink it after every meal. And if acid is produced in your stomach or you have stomach ulcers or acidity, then you should not drink green tea.
Headache
Green tea contains caffeine, so drinking it can cause headaches. People who already have problems like migraine should drink green tea occasionally. If you are sensitive to caffeine then you should avoid green tea.
It can rob you of your sleep
Green tea contains a compound called caffeine that may be harmful to sleep. Although green tea contains very little caffeine, if you are sensitive to caffeine, you may have trouble sleeping. This is because the chemical compounds in green tea inhibit the production of hormones like melatonin, which induce sleep.
Apart from this, green tea also contains L-theanine. This is a chemical that helps to stay calm, but also increases alertness and focus. Which can disturb your sleep. Some research suggests that L-theanine is beneficial for sleep. However, these studies have been conducted mainly on people suffering from ADHD and schizophrenia. Additionally, research suggests that L-theanine blocks glutamate receptors in the brain, which reduces heart rate and aids sleep. But if you drink more caffeinated green tea, such as matcha green tea, it can cause harm. Therefore, if you drink too much green tea, it can cause you to have a bad night's sleep.
iron deficiency
It's true that green tea contains antioxidants, but these properties interfere with your body's absorption of iron. A meta-analysis suggests that it may be dangerous for people who already suffer from anemia or other diseases that cause iron deficiency. One case study found green tea-induced anemia in a 48-year-old businessman who had been drinking 1500 ml (6 cups) of green tea per week for several years. Add lemon to your tea to avoid this side effect. The vitamin C in lemon promotes iron absorption. Alternatively, you can drink grain tea an hour before or after meals. This will give your body time to absorb the iron. As a precaution, avoid green tea if you have anemia.
thins the blood
Green tea can trigger bleeding disorders. A compound found in green tea destroys fibrinogen in the body. These are proteins that help blood clot. Green tea also prevents the oxidation of fatty acids, which can thin the blood. Avoid drinking green tea if you have a problem with blood clotting. Drinking it during periods is also prohibited.
Liver problems
Green tea supplements and excessive consumption of green tea can cause liver damage and liver disease. Experts believe this is due to the accumulation of caffeine which can put pressure on the liver. To avoid this, avoid drinking more than 4 to 5 cups of green tea per day.
Effects on bone health
Drinking too much green tea can lead to bone diseases like osteoporosis. Compounds in green tea inhibit calcium absorption, thereby improving bone health. If you are at risk of bone disease, drink only 2 to 3 cups of green tea. If you drink more than that, take calcium supplements to maintain bone health.
Green tea contains tannins, caffeine and catechins which are dangerous during pregnancy . All these things can prove to be dangerous during pregnancy. Experts say that drinking more than 2 cups of green tea per day during pregnancy or breastfeeding can be dangerous. Excessive consumption of green tea during pregnancy can cause miscarriage. When you drink green tea while breastfeeding, caffeine also reaches the baby through milk. That is why our doctors forbid doing this.
Consult a doctor
Although green tea has several side effects, according to the FDA, green tea is considered safe when consumed in moderation. Most of these side effects are caused by caffeine and only occur when you take large amounts of it. If you are sensitive to caffeine, drink green tea in small amounts or avoid it altogether. If you have a medical condition that puts you at risk for side effects, consult your doctor before drinking green tea.
