Everything will kill you
You shouldn't drink too much water, it could kill you. It's true, water intoxication. Black cohosh causes liver cancer. Selenium increases the chance of cancer. You can die from being too alkaline. And if you take Colloidal Silver, you'll turn grey.
Is it true?
You may have heard the saying: There's 3 kinds of lies: lies, damn lies, and statistics.
This is because studies create data. And data is meaningless until it is interpreted. And therein lies the problem. Although studies are based on factual data, the data can be twisted to prove what you need to.
It's like reporting your finances. When you have to pay tax, you make sure the tax man knows you made no profit, everything costs, and you are barely scraping by. But when you apply for a bond, the bank knows that the money is rolling in, and you have nothing to spend it on, except your bond.
The same is true of health information on the Internet. If you're tired all the time, you look it up. And find out you have a tumor. No wait, it's adrenal fatigue. It might be fibromyalgia. Hang on, it's an adverse reaction to calcium that one person in 150 million have. Then again, you have been going to bed at 3am every night for the past 2 weeks.
What's my point? It's not 'stay off the internet'. It's 'question of what you read.' If a certain viewpoint is portrayed on a subject, who is the source? Do they have anything to gain by putting forward that viewpoint? Do other sites agree? Is it all based on one study? Does the adverse reaction only happen in the most obscure of circumstances or extreme dosage?
If you're still not convinced, I have some great waterfront land available in Florida...
