There's tens of thousands of different "chemicals" in the chicken breasts that we have no idea how it works. Not only that, they're living things, cells, that replicate, can become cancerous, and are known to contain human pathogens (Salmonella, bird flu).
In fact, Salmonella kills 420 people per year in the US alone and infects 1.35 million people [1]. That is a whole lot scarier than tartrazine. Of course, it's 100% natural and organic!
