It would seem to drink it all day is a good idea! But there is a flip side of the coin. Green tea has its own daily value, and to drink more is not worth it. The fact is that green tea leaves can accumulate heavy metals (aluminum and lead), which in large amounts can harm the body. Besides, the tea affects the absorption of nutrients, including calcium, and contains caffeine. Therefore, the rate of green tea is 3 cups a day.
The rule “no more than 3 cups a day”:

- Pregnant, breastfeeding women and those planning conception. The increase in daily allowance of green tea leads to lower absorption of folic acid. This can cause a developmental defect of the fetus. For this group of women is the norm green tea – 2 cups a day.
- People who have insomnia. It is well known that green tea contains caffeine. Of course, its content in the beverage can not be compared with the coffee contents. It is at least three times lower. But those who find it hard to fell asleep should drink the last Cup of green tea for at least 8 hours before bed – during this time, all the caffeine consumed will not in any way affect your sleep.
- Children. The Japanese noticed that children who drank at least 1 Cup of green tea a day are less likely to get infected with the flu. Besides, cajetina contained in green tea promoted weight loss in children prone to obesity. The permissible green tea limits for children are as follows: 4-6 years — 1 Cup, 7-9 years — 1.5 cups, 10-12 years — 2 cups adolescents — 2 cups. Under the “Cup” implied the capacity of about 45 mg.
For whom green tea is contraindicated, and who benefits from it
Contraindications to green tea’s ingestion can be anemia, renal failure, heart disease, osteoporosis, increased anxiety and irritability, and liver disease.
But green tea is worth drinking for older adults. Japanese scientists conducted a study whose results proved that older people retain the capacity and activity if you drink green tea. So, by drinking 3-4 cups a day ability to look after themselves (get dressed, take a shower) increased by 25 %, while eating 5 cups a day at 33 %.
How to drink green tea: 3 rules
1. Not on an empty stomach. Otherwise, green tea can cause nausea and discomfort in the stomach.
2. Sharing tea and receiving products containing iron. Green tea contains tannins, which prevent the normal absorption of iron from food. To get the benefits of tea, and get your quota of iron, drink tea an hour after eating.
3. Correctly brewed. Steep for 2-3 minutes green tea hot water but not boiling water and drink it freshly brewed. If the water is too hot or the leaves will lie there for more than a quarter of an hour in the water, stand out the tannins, and the tea will be bitter, and this drink will have more caffeine, it will release the pesticides and heavy metals.
