Lisa Leake and Vani Hari both have young kids who love Kraft Macaroni & Cheese.
... after determining the Yellow 5 and Yellow 6 dyes used in the U.S. version of the product have been shown to potentially be harmful, they’ve put together a petition asking Kraft to stop the practice.
Various studies have shown that although rare, children might have serious allergic reactions to the dyes. Additionally, separate studies have shown that the dyes could potentially increase the risk of cancer in an individual. All of these could’s and might’s have been documented in a report from the watchdog group The Center For Science in the Public Interest.
The two moms and bloggers put together a petition over at Change.org asking that the company take the dye out of their macaroni products. So far, that petition has amassed over 40,000 signatures. However, Kraft doesn’t seem to be budging. The company says it makes 14 other products in the U.S. that don’t use food coloring and until the FDA says no to yellow dyes, the company will likely stick to the plan.
In the U.K., Kraft uses beta carotene and paprika to color the product.
There are plenty of boxed macaroni products in the market that don’t use food dyes if you are interested in seeking them out. If you are worried about the dye stuff, it's not that difficult to read a label. [emphasis mine]
