bad gas after eating healthy.

I have been eating a diet primarily of junk food almost all of my life. (about 23 years now) I started eating healthy a few weeks ago. Forgoing almost all junk food, and now eat primarily fruits vegitables meats and salads(wherever they fit in)
Now though I seem to have bad gas for an hour or so after eating. This never happened before with all the junk food, so why now?

please send responce to **** as i will be able to see it sooner that way thanks
