Memorandum of support

The Center for Science in the Public Interest strongly supports H.2530/S.1620, legislation that would prohibit the sale of over-the-counter diet pills and weight-loss or muscle-building dietary supplements to minors. These products are widely available and heavily marketed to youth, often with deceptive claims, despite limited evidence of effectiveness. They are also poorly regulated and frequently contaminated with dangerous, undisclosed ingredients. National pediatric experts warn against their use, citing serious health risks including liver damage, hospitalization, and even death. This bill represents a common-sense, urgently needed step to protect young people in Massachusetts. View the resource below to keep reading.

Written testimony in support of House Bills 1130, 1131, 1133, and 1134 in Pennsylvania

Many other states, including California, West Virginia, Utah, and Virginia, have already enacted legislation banning or restricting synthetic dyes in schools. No states have passed bills promoting transparency in the GRAS process or requiring a warning label for synthetically dyed foods or foods containing BHA. By passing these bills, Pennsylvania has the opportunity set a powerful precedent by stopping companies from adding dangerous chemicals to our food in secret and empowering consumers to make more informed choices about the chemicals they eat and feed their children.
