Boxed macaroni and cheese is often a favorite food among youngsters, but a recent study suggests the packaged food contains dangerous, endocrine-disrupting chemicals that have been banned in toys: phthalates. 
Phthalates are a group of toxic additives in plastics. They’re used to make plastics soft and flexible, and are commonly found in artificial fragrances, inks, coatings, adhesives, and other consumer and industrial products, the National Resources Defense Council (NRDC) explains.
These chemicals are approved by the U.S. Food and Drug Administration (FDA) for use in equipment and materials for food handling, processing, and packaging. Because of this, phthalates often wind up in high-fat, highly-processed foods.
