I've heard that about dairy but I've also heard that about wheat... There's all these horror stories about what grains have become thanks to genetic modification. I've learned to cook and live without most grain consumption (exception: occasional rice/sushi). There's a blog called Wheat Belly... I seriously disagree with this "Diet Doctor's" approach (he focuses so much on the fat loss and condemning wheat it's almost ridiculous and kind of like No Wheat Church). However, you can make ANYTHING you would normally have to buy prepackaged if you have the right ingredients and he posts recipes for just about everything you can imagine. Those recipes are a great way to start.
