I'm not going to tell you to stop drinking or eating caffeinated products such as coffee, black tea, soda, alcohol, guarana or chocolate. I'm only asking you to consider what is being said here.
I put this together because based on my clients, I found that most people are unaware of the dangers of caffeine or they don't realize they are having too much. To me, 1 cup a day is too much, because 98% of my clients that go on a cleansing program & drink only 1 cup per day have withdrawals (headaches, fatigue...) for the 1st 2-3 days. I want to protect my brain till the day I die. If removing caffeine from my diet affects my head, then it's being affected every time I have it. There is a fairly new book out called The GAP Syndrome (Gut And Physiology Syndrome). This Neurosurgeon speaks about how certain food & drinks can affect the gut & the brain together. Consider alcohol... if you drink too much alcohol you may vomit (affecting the gut) & you may have a difficult time walking or talking (affecting the brain). And when I saw how many clients drank little water & alot of caffeinated drinks, I decided to ask a Nephrologist (a kidney specialist) why there are so many people, young & old, on dialysis? He said 2 things: people eat too much pork & beef (which is hard on the kidneys believe it or not) and...too much soda, coffee, etc and not enough water. The water in soda does not count for water, as well as with coffee, iced coffee, black tea or green, iced tea, hot chocolate, etc.

I grew up seeing & knowing people with diseases like cancer, diabetes, heart disease, etc.  When I was about 11 yrs old, I remember telling my dad that I didn't want to get cancer...what could I do? I never forgot his answer...he said, stimulants like coffee, black tea, soda, alcohol, chocolate... may not necessarily cause cancer, but they may trigger it off to spread/grow faster (doctors can't detect cancer until you've had it for many years, so no one really knows if they have cancer). In other words, if you have cancer (but don't know you have cancer), and you're regularly ingesting some kind of stimulant, ...that stimulant may speed up the cancer. He didn't give me any research documenting this, but it made alot of sense to me as a young girl & it still makes sense to me today! Also, the above stimulants are all highly addictive...so will you be able to stop your addiction if your life depended on it? I never wanted to put myself in that struggling-type of position...so I NEVER got into coffee, or any stimulant. I am so grateful to God that my parents had this knowledge (in the 60's) & taught it to us. Parents...teach your children about these things. They're sponges and they're never too young to learn! I wasn't.

There is so much to say about caffeine. There are a some "so-called" positive effects & many negative effects. I hope you will see that the negative effects of caffeine far outweigh the positive effects. Everyone needs to make their own choices for their health.
