There are more important things to obsess about. Read the studies. The cumulative effect you're referring to is through transdermal administration. If that's not the case, provide evidence to the contrary.
Bad analogy.
Oh, and just what ingredient in a bottle of Heinz is a paraben?
OK, "Princess" why don't you represent that instead of a single muscle and fitness article you have read each and every one of these articles (studies demonstrating an estrogen-mimic effect of parabens) and feel qualified to now advise posters that ingestion of parabens is completely safe and not better avoided:

Let me guess, you don't actually know. (Sort of like when you ASSumed that Brewers Yeast, since it was a vegetable source of protein, was therefore an incomplete source of protein and therefore dutifully reported such to another poster that it was an incomplete protein. Of course, completely false, as proven by actually reading the label and observing the amino acid profile).
And by the way "Princess" the high fructose corn syrup in ketchup and the high fat content of mayo isn't all that good for you either, but I'm sure you knew that.
