More than 10,000 additives are allowed for use in food sold in the U.S. These chemicals are added to products for a variety of reasons, including to add color or shine, to stabilize artificial flavors and to extend shelf life. Many food chemicals have not been thoroughly reviewed for safety or have not been re-reviewed for decades with the newest science in mind. Scientists have recently expressed concern about the potential health harms associated with some of these additives.
We eat food because we need it to live. But many foods contain additives that not only don’t provide nutrients, but also can be bad for you – and that’s perfectly legal. Food additives are used by manufacturers to do things like lengthen shelf life or provide more color or shine.
