Found in some samples or products

These come from where it was grown, how it was processed or cooked, or what it was made into. They are not about the ingredient itself, so the signal does not count them.

• Pesticide residues on fruit⁷

  Raspberries tested after spraying still held small amounts of several pesticides, though levels stayed below the daily intake limits.

How it’s made and used

• Blood levels of berry nutrients²

  In people with prediabetes, eating raspberry daily for four weeks raised gut-made breakdown products in the blood.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
