Wom, if you drink too much water it can poison you and kill you.

If you drink too much coke it can be bad for you.

The same goes for damned near anything.

There is an LD 50 (dosage at which 50% of the test population will die from acute effects) that has been lab tested for Corn Syrup, sugar and a few other innocuous foods. I could write up an article on them in such a manner that you'd be afraid to eat anything in your fridge.

The point is, as the old saying goes, all things in moderation.
