Several Pasadena schools have banned Flamin' Hot Cheetos, citing nutritional value as the reason.
The snack-size bags contain 26 grams of fat and a quarter of the amount of sodium recommended for an entire day.
The Pasadena Unified School District has eliminated candy and junk food at elementary school campuses and limited such snacks for older students.
The district allows individual principals to decide food choices available at their schools.
The principal of Andrew Jackson Elementary School in Pasadena said if students are caught bringing Flamin' Hot Cheetos to school, the snacks will be confiscated.
"If it were up to me, I'd say no chips of any kind," said Jackson Elementary teacher Monica Villegal.
Frito-Lay, which makes and sells Cheetos, said it remains "committed to responsible and ethical marketing practices, which includes not marketing our products to children ages 12 and under."
"We also do not decide which snacks are available on school campuses and do not sell snack products directly to schools," the statement says.
Schools across the country have banned the chips. A school district in Illinois, which sold 150,000 bags of Flamin' Hot Cheetos each year, took the snack off its menu.
