A Healthier Me

How much fiber can a person eat in a day before she explodes? I've decided to try and eat a little healthier and have purchased some Fiber One yogurt and poptarts. I figure if I can have a poptart, I'm good. Reminds me of my childhood. However, I am afraid that my colon won't recognize me if I continue this path of salad, fruit and fiber.

I'll let you know if something happens.
