The downside of drinking a lot of green tea.

 

   Tea is one of the healthiest drinks, but it can still have negative effects if you use it incorrectly.

Tea has many effects such as prolonging life, increasing metabolism, promoting weight loss, supporting memory …

But you’ve probably heard the saying: “Too much good can turn out to be bad”. That statement holds true even for healthy drinks like tea.

However, drinking too much tea has the potential to harm the body. One study examined 34 healthy people who drank and did not drink tea for 5 weeks. The amount of tea to drink per day is 10g of tea leaves mixed with 1 liter of water.

Since then, scientists have drawn some conclusions about the side effects of drinking tea:

* Reduced iron absorption.

According to research published in the journal Food Research International, too much tannin – the substance that gives drinks like tea and wine a bitter taste – inhibits the body’s absorption of iron.

Therefore, you should drink moderate amounts of tea and eat iron-rich foods regularly.

* May be exposed to toxins.

Tea leaves carry the risk of absorbing toxic compounds from the soil or growing process. Studies have found toxins in many different types of tea.

A study published in the journal Toxicology found that 30 types of tea – including black, green and oolong teas – contained lead.

Accordingly, 73% of tea brewed for 3 minutes has lead content at an unsafe level for pregnant and lactating women. Aluminum levels are higher than recommended in 20% of brewed teas.

* Damage to teeth, bones and joints.

Scientists have found high levels of fluoride in tea bags. If you consume more than 4 cups of tea (one liter) per day, you may exceed the allowable fluoride intake.

* Causes anxiety, trouble sleeping or headaches.

Tea contains caffeine (20 – 60 mg) per cup, less than coffee. But if you drink too much tea, that caffeine will increase, disrupting sleep, heartburn, headaches, and anxiety.

This negative effect tends to occur when too much caffeine is consumed, from 100 to 200 mg per day (2-10 cups depending on the type of tea).

* Lemon tea may contain higher levels of heavy metals.

According to research published in the journal Food Composition and Analysis, black and green teas contain citric acid that can be high in aluminum, cadmium, and lead.

In particular, lemon tea has a content of this substance 10 times higher than other teas. Although citric acid is an antioxidant ingredient, promoting beneficial elements in the gut but also adding toxic metals.
