Pros and Cons of Green Tea

Many reports show that drinking green tea can be very beneficial to our health, which is not surprising considering that green tea has been used as traditional medicine for so many years. In areas such as India, China, Japan and Thailand, green tea has been used to help everything from controlling bleeding and helping heal wounds to regulating body temperature, blood sugar and promoting digestion.

Benefits of Green Tea

The potential benefits of consuming green tea have, for the most part, not been proven by scientific research, however, some research has credited green tea with the following health benefits.

  • Preventing cancer.
  • Treating multiple sclerosis.
  • Stopping diseases such as Alzheimer’s and Parkinson’s.
  • Neutralising the spread of free radicals.
  • Reducing the negative effects of LDL (bad) cholesterol.
  • Raising metabolism.
  • Encourages the formation of scabs if applied directly to a wound.

Negatives of Green Tea

The major concern with drinking too much green tea is the caffeine it contains. Too much caffeine can cause nausea, insomnia or frequent urination.

New Scientist points to recent research has shown consuming very large quantities of green tea can be dangerous as it can cause damage to the liver and kidneys:

Green tea is good for you, but only if drunk in moderation. While the polyphenols in green tea are credited with preventing heart disease and cancer, it seems they can cause liver and kidney damage if consumed in very large quantities, a review of studies into the toxicity of polyphenols has shown.

He stresses that up to 10 small cups of green tea a day is fine. Problems are likely in people who take supplements, which can contain up to 50 times as much polyphenol as a single cup of tea.

In summary, keeping drinking green tea for its numerous benefits but the benefits of taking supplements may outweigh the risks.

  1. Hi

    I have heard that drinking too much green tea, can cause the fat around our eyes to dissolve.
    I have a cousin who drank 3 large cups of green tea everyday for a year in order to decrease triglycerid level of her blood.She succeeded in that but also the fat around her eyes disolved.Does that have to do with drinking too much green tea?
    I appreciate your reply.

    Yes it can dissolve fat because it raises the metabolism that’s why it is very popular among dieters who want to lose weight.

  5. hey

  6. Use your common sense and you’ll be fine. You do have common sense, don’t you?

  7. can green tea clear up your skin?

    • Celeste says:

      Billy; it can help if you use damp tea leaves, especially mixed with honey, and rub it onto your skin. Oatmeal also helps to soften your skin. Hope that helps :)

    I drink 2 cups of green tead a day, and its helped me loose wight, but I have been told that because it cleanses you that you might flush out some important vitamins. I’m concerned cause lately i feel wweak and with no energy, could the green tea do this? Please advice

    • I drink about 4 – 5 cups of green tea a day, and at the beginning I felt strange but soon my body got used to it!

      I lost some weight on two cups, but I’ve upped my dosage and have gone from weighing 60, to 54kg, while eating probably worse than I was before! Which has been amazing for me, after trying everything to budge those extra pounds.

      I take a multivitamin and krill oil pills everyday to make sure my vitamins aren’t flushed out. But, found that if I drink it on an empty stomach, I feel quite ill.

    • Caffeine is a diuretic, so it can flush out vitamins if you drink too much green tea. If you do drink quite a bit, take vitamin supplements and drink drinks rich in electrolytes (potassium + salt) like coconut water. Gatorade works, but it has less. Banana is good too.

  10. Sara: what is the best time during the day for drinking green tea?

    I follow the abs diet and in the book it said that drinking green tea after meals is good for you. It increases the metabolism and it makes me feel energetic even if i ate more than i should have.

  11. I understand that Caffein brings about negative effect on our skin, will drinking green tea then, deteriorate our skin’s condition?

    will our body build up tolerance towards the caffein in green tea(like those of coffee), thus making it less effective in keeping us awake subsequently?

  12. green tea causes premature ejuculation is it true?

  13. i drink about 4-5 cups green tea per day
    and i finf myself needing to urinate alot.

    i want to ask , does green tea cause frequent urination?

    Thanks

    • Beach_babe says:

      Green tea in itself (without the water) is considered a natural diuretic, a subtance that increases the production of urine. Obviously all water-based foods are natural diuretics, and so are coffee and asparagus.

  14. lol… any liquid causes frequent urination man :)

  15. around how many cups of green tea is ideal every???

  16. I have heard that green tea extract raises your heart rate, and this is why it burns fat. But isn’t this also bad for your heart?

  17. idealy, probably about a quart, give or take a cup, but it also depends on your activities, for those who constantly drink green tea, we tend to be skinnier and more energenic, but we are constantly active.

  18. What kinda green tea are you all drinking.

  19. I drink about 18 cups a day :S it basically just caused me to pee alot. I eventually lost about 10kg. but i also dieted. i think the green tea helped

  20. I was wondering the same thing about how much is too much, Except i drink green ice tea and over the last week i’ve has about 1litre a day. I feel fine but i was concerned when i heard that too much green tea is bad for you and was wondering like i said at the beginning, exactly how much is too much?

  21. Hi, does green tea causes the bleeding? Cz that’s the problem I startd to have after starting to drink it, I bleed evn when its not my periods and myb its takes 1 or 2days not heavy though but I’m worried. If yes, what to I do to stop it

  22. I can hardly believe the silly questions I have just read here or the sometimes sillier answers.
