FDA Releases Total Diet Study Interface

The U.S. Food and Drug Administration (FDA) announced the release of the Total Diet Study Interface (TDSi), an interactive web-based tool that provides streamlined access to findings from FDA's Total Diet Study (TDS), which monitors levels of nutrients and contaminants in foods eaten by people in the United States.

Concurrent with this launch, FDA released the most recent cycle of TDS data, including results from fiscal years 2021 and 2022. TDSi includes TDS datasets from fiscal year 2018–2022.

By transitioning from traditional publication methods to a more dynamic, user-interactive platform, FDA said it aims to provide stakeholders with enhanced access to critical food safety and nutrition data.

FDA's TDS is a continuous monitoring program that systematically collects, prepares and analyzes chemical contaminants and nutrients in foods representing the average U.S. consumer's diet. This new enhancement to the TDS surveillance program provides data to assess cumulative exposure to various contaminants in food.

According to FDA, TDSi offers:

• Comprehensive data visualization. Interactive graphics and charts that enable users to explore TDS findings efficiently and intuitively.
• Enhanced transparency. User-driven access to detailed analytical results with full dataset download capabilities for researchers and stakeholders.
• Historical scope. Complete datasets for nutrients and contaminants (including elements, radionuclides and pesticides) in foods collected since 2018.
• Ongoing updates. Regular incorporation of new TDS data as it becomes available.
