The Dirty List

The Ingredients Nobody Explains to You.

What they are, where they hide, what the research says, and what to use instead. No fear. Just facts.

Harmful Ingredients

Corn Syrup (Glucose Syrup)

Formaldehyde (in Hair Smoothing Treatments)

BHA (Butylated Hydroxyanisole)

PFAS (Forever Chemicals)

Ractopamine

Maltodextrin

Bisphenol A (BPA) (can lining chemical)

Titanium Dioxide (E171)

Artificial Sweeteners (Aspartame, Sucralose)

Emulsifiers (Polysorbate 80, CMC)

Potassium Bromate

TBHQ (tert-Butylhydroquinone)

Description:

TBHQ (tert-Butylhydroquinone) is a petroleum-derived synthetic antioxidant used to prevent fats and oils from going rancid. It extends shelf life in processed foods, especially those cooked in or containing industrial oils. The FDA permits it at concentrations up to 0.02% of a food’s fat content.

Found In:

  • Fast food (especially fried items like chicken nuggets and fries)
  • Microwave popcorn
  • Frozen pizza and frozen meals
  • Crackers, chips, and packaged snacks
  • Ramen noodles and instant soups
  • Commercial cooking oils and shortening
  • Processed peanut butter
  • Toaster pastries
  • Frozen breaded chicken and nuggets
  • Fish sticks
  • Refrigerated biscuit and crescent dough
  • Peanut butter cracker sandwiches
  • Cereal and granola bars
  • Packaged cookies

Health Impact:

TBHQ has raised red flags in toxicology research. At higher doses in animal studies, it caused stomach tumors and DNA damage. The National Library of Medicine notes acute symptoms such as nausea, vomiting, and ringing in the ears, but only at a 1 gram dose, far above what you would ever get from food. A 2020 study from the Environmental Working Group found TBHQ in over 1,250 processed foods in the U.S. food supply. Research published in the International Journal of Molecular Sciences has studied TBHQ’s effect on immune cell function in laboratory models, which is one reason it remains an area of ongoing research. While individual servings contain small amounts, daily exposure across multiple processed foods creates a cumulative concern.

Healthier Alternatives:

  • Foods preserved with vitamin E (tocopherols) instead of TBHQ
  • Snacks cooked in coconut oil, avocado oil, or olive oil
  • Air-popped popcorn with real butter instead of microwave bags
  • Homemade versions of fried foods using stable cooking fats
  • Check labels for “TBHQ” or “tert-Butylhydroquinone” in the ingredient list

Scientific Evidence:

  • EFSA Panel on Food Additives (2004): Safety assessment noting liver enlargement and tumor promotion in animal studies at elevated doses
  • Gharavi et al. (2007, International Journal of Molecular Sciences): TBHQ modulates immune cell function, potentially impairing T-cell mediated immune responses
  • National Library of Medicine Toxicology Profile: Documents acute toxicity symptoms at 1g ingestion including nausea, vomiting, tinnitus, delirium
  • Butchko & Voelker (1997, Food and Chemical Toxicology): Review of TBHQ safety showing dose-dependent stomach forestomach hyperplasia in rodents
