Pizza Hut and Taco Bell restaurant chains will eliminate cancer-causing ingredients in food they offer.
The shift owes to the critics aroused in the society.
People, who became aware of the cancer-causing products, the restaurants provided, did not agree to put up with it and abandoned the corporate food chains.
Taco Bell said it will try the novel concept of using real pepper as opposed to "black pepper flavor" in its beef, and revealed plans to eliminate trans-fats in its foods by the end of the year.
The company should also get rid of their Yellow number 6 nacho cheese, an ingredient shown to cause cancer in lab animals, as well as remove Blue number 1 from its avocado ranch dressing, as well as carmine from its tortilla strips.
"Yellow 6 caused adrenal tumors in animals. It may be contaminated with cancer-causing chemicals and occasionally causes severe hypersensitivity reactions,"a study by the Center for Science in the Public Interest found in 2010.
