Yes or No

Start researching tea and you will find that researchers have all kinds of things to say. Some say tea helps reduce the risk of cancer, some say it doesn't. Some say it reduces the risk of some types of cancer, but increases the risk of others. And so on and so forth.

The more I study the benefits of various foods the more firm I am in my belief that moderation in all foods and beverages is key. If you overdose on a particular food, even if it is a healthy food, it is not beneficial to your body. On the flip side of that, it is not a huge problem to eat food that is considered "unhealthy" as long as you don't do it frequently or a lot at a time.

Here is what my sister has to say on the topic:
"Yes it is very good to eat everything in moderation. Although what is moderate for one person may not be for another. The key is to find out your personal needs based on sex, age, size, activity level etc. Oh a really good book to read is 'The Eat Clean Diet.' The book is very healthy and is not full of dangerous diet fads and trends."

"Oh, tea is good, but you need to consume lots of water along with it. Both coffee and tea take a lot of water to digest. They act as mild diuretics, even though they contain lots of water."
