California legislature passes bill banning ultra-processed foods from schools—and defining them

So many readers have sent me notices about California’s Senate having unanimously passed a bill banning ultra-processed foods from schools—and defining what they are—that I just have to write about it.

The bill is here.  The legislative analysis is here.

Two things about this bill are noteworthy.

I.  The bill defines ultra-processed foods. 

An ultra-processed food:

Contains one or more of the following

  • Surface-active agents
  • Stabilizers and thickeners
  • Propellents, aerating agents and gases
  • Colors and coloring adjuncts
  • Emulsifiers and emulsifier salts
  • Flavoring agents and adjuvants
  • Non-nutritive sweeteners [D-sorbitol, erythritol, hydrogenated starch hydrolysates, sucralose, isomal, lactitol, luo han fruit concentrate, maltitol, steviol glycosides, thaumatin, xylitol)

And contains one or more of:

  • Saturated fat at 10% or more of calories
  • A ratio of mg sodium to calories of more than 1:1
  • Sugars at 10% or more of calories

II.  The bill summarizes existing California laws related to school food.  These:

  • Ban foods containing brominated vegetable oil, potassium bromate, propylparaben, red dye no. 3.
  • Provide free breakfasts and lunches to all students.
  • Restrict foods sold outside the schools meals to those that are reasonably healthy.
  • Limit fat, saturated fat, sugar, sodium, and calories in competitive foods.
  • Restrict competitive beverages to drinks to those that are reasonably healthy
  • Prohibit several synthetic color additives.

Comment: The bill has yet to be signed by the governor.  I hope he does.
