You can dodge risky food additives (like aspartame and food dyes) if you know what to look for. But it’s trickier to sidestep contaminants (like endocrine disruptors and mercury) that don’t show up on a food label.
CSPI ranks food additives—from “safe” to “avoid”—in this definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance.
Caffeine is safe for most (non-pregnant) adults if they don’t overdo it. But caffeine—and especially energy drinks—have downsides, so don’t get carried away.
The FDA doesn’t require companies to disclose caffeine, but many voluntarily do. We track how much caffeine is in their coffees, teas, kombuchas, sodas, energy drinks, coffee ice creams and yogurts, energy chews, over-the-counter pills, and more.
Too much caffeine can do harm, but lower levels of caffeine (or coffee) have been linked to a lower risk of type 2 diabetes, better exercise performance, and other health outcomes in non-pregnant adults.
