Two food bloggers from North Carolina have created a petition to make Kraft Foods stop using dye to color its macaroni and cheese.
The two women say the dyes, Yellow No. 5 and Yellow No. 6, are not used in other countries and can cause hyper-activity in children— as well as asthma and migraines.
Their online petition has already received more than 50,000 signatures.
A spokesperson for Kraft says the company takes the concerns seriously and follows the laws in the countries where its products are sold.
