"A Pizza Hut, a Pizza Hut, Kentucky Fried Chicken and a Pizza Hut…" Who could forget the montage of students screaming at the top of their lungs to fast food giants in the world-famous documentary Supersize Me?

While Morgan Spurlock definitely raised eyebrows with his McD's experiment and brought to attention the lacking nutrition in most processed and fast-food options, little was done about it. It became the collective belief that companies like McDonalds would never change, and consumers would just need to take initiative and abstain from low-quality fare.

But in light of increased consumer interest in becoming healthier and preventing modern-day diseases of affluence, a growing amount of restaurant chains are choosing to 'get with the times' and adapt their menu – even if slightly – to cater to their more health-conscious  clientele.

Jumping in on the action are the fast food favorites Pizza Hut and Taco Bell.

Yum! Brands, which owns both Taco Bell and Pizza Hut, announced just this week that they will stop putting artificial ingredients like high fructose corn syrup, black pepper flavor, added trans fat, and other fake ingredients into the foods they sell.
