Nope, becuase it isn't even junk science. It's just irrelevant, we've known for decades that overcooking reduces the nutritional value of everything. Because most "processing" involves cooking or increased chance/rate of oxidation, you have the rule of thumb that the more it is processed the less it is food.

That being said, if you fill up on even over cooked broccoli, you are still less likely to indulge in stuff that is higher in fats and cholesterol, thus reducing your heart health risks. Odds are you eat more fiber to, which reduces cholesterol and certain cancer probabilities. Put bluntly, people eat vegetables without butter or sauces and the like are generally more likely to be eating better period.

Slow news day, someone wanted to have something that sounded alarming and flamboyant in their "science for the illiterate masses" page, becuase half the idiot who read will it think that boiled broccoli somehow causes cancer and their share their newfound "wisdom" with seven or eight other people and readership will go up becuase that "news" service was the firstest with the mostest when it came to cutting edge scientific health facts that no one else is brave enough to cover. *blows a razzberry at yahoo's news staff*

But thanks for looking after us. *pats picard on the head*
