Lead in Food — FDA Total Diet Study
How much lead the US FDA measured in everyday foods, food by food.
Good to know
Lead concentrations (µg/kg = ppb) in 308 foods from the FDA Total Diet Study FY2018–FY2022. Values shown are mean hybrid-bound concentrations — the best estimate of actual dietary lead exposure, averaged across seasons, regions, and years.
Minimize lead exposure on a plant based diet
A diverse whole-food plant based diet naturally reduces heavy metal exposure. Vary your grains, rotate vegetables, and choose fresh or frozen over canned products. Washing produce thoroughly removes surface contamination. See our arsenic rankings and cadmium rankings for a complete picture of dietary heavy metal exposure.
Questions
What is the FDA Total Diet Study?
The FDA's Total Diet Study is an ongoing market-basket survey measuring contaminants and nutrients in ~300 representative foods purchased from US supermarkets four times per year across different regions. Foods are prepared as they would be eaten (cooked or ready-to-eat). It has been running since 1961, making it the world's longest-running dietary contaminant monitoring program. This data covers FY2018–FY2022.
What is the FDA "Closer to Zero" initiative?
The FDA's Closer to Zero initiative aims to reduce dietary exposure to lead, arsenic, cadmium, and mercury — particularly in foods consumed by babies and young children. Interim Reference Levels (IRLs) set thresholds for what's achievable through good manufacturing practices: 10 ppb for fruit/vegetable baby foods, 20 ppb for grain snacks. These are not safety thresholds but manufacturing targets — since no safe lead level has been established.
What is the hybrid bound method and why is it used?
When a contaminant is below the detection limit, its true value is unknown — it could range from zero to the reporting limit. The hybrid bound assigns the reporting limit to detected samples and zero to non-detects, then averages them. This is recommended by EFSA and Codex Alimentarius as the best estimate for dietary exposure — more realistic than the upper bound (which assumes all non-detects are at the limit) and more conservative than the lower bound (which assumes all non-detects are zero).
Does a whole-food plant based diet reduce lead exposure?
Research consistently shows that people who eat predominantly whole plant foods have lower dietary heavy metal exposure compared to those who consume more processed foods, canned meats, and certain fish. A varied whole-food plant based diet — especially one rich in fresh fruits, legumes, and diverse grains — is among the most effective dietary strategies for minimizing lead intake.
Are organic plant foods lower in lead?
Organic farming prohibits synthetic fertilizers that can introduce lead, and organic soils tend to have lower contamination from industrial agriculture. However, organic certification does not eliminate lead — historical contamination persists in soils for decades. Rotating food sources and buying from diverse regions are practical strategies for minimizing exposure regardless of organic status.
Does cooking remove lead from plant foods?
Cooking has limited effect on lead in plant foods. Boiling vegetables in large water volumes can leach some lead, slightly reducing levels. However, internally absorbed lead cannot be removed by cooking. The FDA TDS data was collected from foods prepared as normally eaten — so the concentrations shown already account for typical cooking methods (boiling, baking, roasting, etc.).
