If you’ve been following nutrition news lately, you might have seen some alarming headlines about sweet potatoes. One viral claim suggests sweet potatoes are “toxic” and should be avoided. Another recent story noted that the CDC ranked sweet potatoes lower on its “powerhouse” fruits and vegetables list . It’s enough to make anyone wonder: Is my favorite comfort food actually bad for me?
Let’s cut through the confusion. I’ve looked at the science behind the claims, and here’s the reassuring truth: sweet potatoes are not dangerous for the vast majority of people. They are a nutrient-dense whole food with significant health benefits. However, like any food, there are specific situations where certain individuals might need to exercise caution.
Here’s what you need to know.
Claim #1: Sweet Potatoes Are “Toxic” or Contain Dangerous Chemicals
The Truth: This claim is misleading and overblown.
The concern stems from two separate issues: pesticide residues on the skin and a completely unrelated warning about green potatoes.
Pesticide Residues on the Skin
Some viral videos have claimed that sweet potato skins contain “toxic” levels of pesticides. The reality is more nuanced. The Environmental Working Group (EWG) did note that potatoes made their “Dirty Dozen” list in 2026 . However, experts caution against overreacting.

The solution is simple: “If you’re concerned about pesticide content on the sweet potato skin, I would suggest scrubbing them under running water with a stiff brush or peeling them to help reduce exposure,” says Meghan Windham, MPH, RD, LD . You don’t need to give up sweet potatoes entirely.
-
Expert consensus: “You definitely don’t need to avoid eating the skin or twice baked potatoes, which are so good,” says nutritionist Amanda Sauceda, MS, RD .
This Warning Is NOT About Sweet Potatoes
The “green potato” toxin warning you may have seen circulating is about white potatoes, not sweet potatoes. White potatoes that turn green or sprout produce a toxic compound called solanine, which can cause nausea and neurological symptoms . This is a well-established food safety guideline for standard potatoes. It does not apply to sweet potatoes. Don’t let this confusion scare you away from a perfectly safe vegetable.
