The Center for Science in the Public Interest is a consumer advocacy organization whose twin missions are to conduct innovative research and advocacy programs in health and nutrition, and to provide consumers with current, useful information about their health and well-being. In general, CSPI's three main goals are:

To provide useful, objective information to the public and policymakers and to conduct research on food, alcohol, health, the environment, and other issues related to science and technology;
To represent the citizen's interests before regulatory, judicial and legislative bodies on food, alcohol, health, the environment, and other issues; and
To ensure that science and technology are used for the public good and to encourage scientists to engage in public-interest activities.
