Everything is contaminated.
Nothing is really safe to eat or drink anymore.
As for the topic of sugar...
I don't know how much Gatorade you are consuming but Gatorade contains about 14 grams(2.95 teaspoons) of sugar in a 240-milliliter serving.
Compared to a can of Coke that has 39 grams(8.219 teaspoons) of sugar.
It doesn’t look like your drink consumption is bad at all. It's better than most peoples drinking habits I'm sure. The only thing I would change
is switching coffee for green tea.
