What Hidden Ingredients Are Lurking in Your Food?
Potassium bromate is a dough-strengthening chemical used in some breads and baked goods to help dough rise higher and hold shape. You’ll often see it listed as “potassium bromate” or “bromated flour.” It’s mainly a “perfect loaf” ingredient for mass production—not a nutrition ingredient.
White bread / sandwich bread
Hamburger & hot dog buns
Bagels
Pizza crust
Flour tortillas
Potential concerns:
Cancer risk flags in animal research
Adds an unnecessary chemical exposure for something as common as bread
Especially relevant when bread is eaten daily (high frequency exposure)
DD takeaway: If you eat bread often, this is one ingredient worth avoiding completely.
Look for breads that say:
Unbromated flour
No potassium bromate
Organic (still check labels, but generally cleaner ingredient standards)
Better “clean bread” pattern:
Ingredients that look like: flour + water + yeast + salt
Optional: olive oil, seeds, herbs — but no lab-sounding conditioners
The International Agency for Research on Cancer (IARC) has classified potassium bromate as “possibly carcinogenic to humans (Group 2B)” based on animal evidence.
It is also regulated differently depending on location, and its risk profile is why many health advocates recommend avoiding it when possible.
