Tea or coffee?

Am addicted to 2-3 cups of tea or coffee a day(difficult to stay up in office otherwise 🙂 ). Always had a pre-conceived notion that too much of caffeiene is bad for health but wanted to find out the exact details.

According to an article on BBC’s wesite, Instant coffee has about 61-70 mg of caffeine per cup of coffee whereas tea can have from 15-75 mg of caffeine per cup, depending on the brand. People with high blood pressure and pregnant women are advised to limit their caffeine consumption and pregnant women are supposed to restrict their consumption of caffeine to less than 300 mg a day. Both tea and coffee contain polyphenols that can bind to iron, making it difficult for our bodies to absorb. Avoiding tea and coffee during and around mealtimes is important for people at risk of iron deficiency.

But for the rest of the population, there’s no evidence caffeine does any long-term harm.

Howver, there have been some research to prove that both coffee and tea do have beneficial effects, for example coffee may reduce the chance of getting kidney stones or gall stones. However, according to this aritcle in the website of ABC News, more than 4 cups of coffee in a day is not recommended.

Tea contains some useful minerals such as zinc, manganese and potassium, and scientists are researching its potential to reduce the risk of coronary heart disease and some cancers.

There is the strong suggestion that the antioxidants in tea – whether it’s black, green or white – have health benefits. Antioxidants can prevent inflammation of the blood vessels, and it has been linked to reduced risk for cancer. In terms of antioxidants, white tea has the most, followed by green tea, black tea and coffee.

      No…white tea is the uncured and unoxidised tea leaf, and has a slightly higher content of caffeine. Its a specialty in China.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
