The FDA's GRAS program — "Generally Recognized As Safe" — was created in 1958 for obvious things like salt and vinegar. Today it's a loophole that lets food companies declare their own chemicals safe, in secret, without FDA review. Here's what's in your food and what the research actually shows.
Under the 1958 Food Additives Amendment, any substance added to food requires FDA approval — unless it's GRAS. GRAS ingredients are exempt from review. That was meant for things like table salt and baking soda.
In 1997, the FDA made it worse: companies can now voluntarily notify the FDA about new GRAS ingredients. Voluntarily. And if the FDA starts asking hard questions, the company can withdraw the submission to stop the review — and still use the ingredient anyway.
"We simply do not have the information to vouch for the safety of many of these chemicals." — Michael Taylor, former FDA Deputy Commissioner for Food, 2014
A corn-derived sweetener found in sodas, breads, ketchup, sauces, cereals, yogurt, and most packaged snacks.
Directly linked to Type 2 diabetes, visceral fat accumulation, fatty liver disease, elevated LDL cholesterol, and cardiovascular disease. Studies show HFCS raises triglycerides and uric acid levels in the blood — both heart attack risk factors.
Sodas, fruit juices, bread, crackers, salad dressings, ketchup, flavored yogurt, canned soups, cereal bars, fast food condiments.
GRAS — self-declared by manufacturers. No independent FDA safety evaluation required.
The EU limits HFCS use via sugar quotas. Countries that use cane sugar instead show measurably lower Type 2 diabetes prevalence.
Synthetic preservatives used to prevent fat from going rancid in packaged foods.
BHA is classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC). Animal studies show cancer tumor growth. Both BHA and BHT are flagged as potential endocrine disruptors by the European Commission.
Potato chips, cereals, chewing gum, vegetable oils, frozen meals, lard, shortening, beer, cosmetics.
FDA: GRAS. IARC: Possible carcinogen. European Commission: Potential endocrine disruptor. Center for Science in Public Interest: Avoid.
The EU has restricted BHA use significantly. Many manufacturers are now switching to Vitamin E as a safer alternative — it works just as well.
A petroleum-derived preservative used in cooking oils and fried fast foods to extend shelf life.
Linked to stomach tumors, liver enlargement, and convulsions in humans at high doses. Animal studies show paralysis. Research published in Toxicology Reports documents cancer links at elevated doses.
McDonald's chicken nuggets, fast food frying oils, microwave popcorn, crackers, fish products, frozen pizza.
GRAS — restricted to 0.02% of fat/oil content. Approved 1972. No updated safety review in over 50 years.
Japan and several European nations have restricted or banned TBHQ in food products. The US still uses it widely in fast food.
Preservative salts used in cured and processed meats to prevent bacterial growth and maintain pink color.
Linked to increased risk of colorectal cancer, stomach cancer, and pancreatic cancer. When sodium nitrite is heated (as in frying bacon), it reacts with amino acids to form nitrosamines — potent carcinogens.
Bacon, hot dogs, ham, deli meats, salami, pepperoni, jerky, smoked fish, corned beef.
GRAS. Despite cancer links, FDA allows it because "benefits outweigh risks" — i.e., it prevents botulism in processed meat at scale.
Several countries require warning labels on nitrite-cured meats. The EU mandates lower maximum nitrite levels than the US.
A synthetic antioxidant used with BHA and BHT to preserve fats in processed foods.
A U.S. government study found more cancer in rats given low doses of propyl gallate than those given high doses or none — a red flag for non-linear dose response. Flagged as an endocrine disruptor.
Microwave popcorn, meat products, soup mixes, chewing gum, mayonnaise, frozen meals. Often unlisted when under threshold.
FDA: GRAS. Restricted or banned in several countries. CSPI recommends full avoidance.
Vitamin E (tocopherols) serves the same preservative function with no known carcinogenic risk.
An artificial sweetener 200x sweeter than sugar, used widely in "diet" and "sugar-free" products.
WHO's International Agency for Research on Cancer classified aspartame as a possible human carcinogen (Group 2B) in 2023. Studies also link it to glucose intolerance, disrupted gut microbiota, insulin resistance, and depression.
Diet sodas, sugar-free gum, yogurt, tabletop sweeteners (Equal, NutraSweet), protein powders, flavored water.
FDA maintains GRAS status and "safe at current levels." WHO IARC now says: possible carcinogen. The FDA has not updated its position since the 2023 WHO classification.
Stevia and monk fruit are plant-derived zero-calorie sweeteners with no known carcinogenic or metabolic risk in current research.
A thickening and stabilizing agent derived from red seaweed, used to improve texture in dairy and processed foods.
Animal studies link carrageenan to intestinal inflammation, ulcerations, and colorectal tumors. Researchers have documented it triggering inflammatory pathways in human cells. Particularly concerning for people with IBS or Crohn's disease.
Chocolate milk, infant formula, deli meats, plant-based milks (almond, oat, soy), whipped cream, cottage cheese, ice cream.
GRAS. Despite a 2016 petition to ban it and the National Organic Standards Board recommending its removal from organic foods, the FDA declined to act.
Many plant-based milk brands now offer carrageenan-free versions. Check labels — some almond milks removed it after consumer pressure.
A vegetable oil bonded with bromine, used to prevent citrus flavoring from separating in sodas.
Bromine accumulates in fatty tissue including the brain. Linked to thyroid disruption, neurological impairment, memory loss, and skin lesions. Bromine directly competes with iodine in the body, disrupting thyroid function.
Mountain Dew, Gatorade (some flavors), citrus sodas, some sports drinks and energy drinks.
FDA declared BVO no longer GRAS in 1970. It remained in the US food supply for 54 more years. The FDA finally banned it in July 2024 — after California banned it first in 2023.
California's Food Safety Act (2023) forced the national issue. The FDA acted only after a state law embarrassed it into moving.
A petroleum-derived synthetic red food dye used to give candy, cherries, and beverages a bright red color.
Linked to thyroid tumors in animal studies. The FDA's own scientists flagged cancer risks in the late 1980s. The dye was already banned from cosmetics and externally applied drugs in 1990 — but remained in food for 35 more years.
Maraschino cherries, candy (like Peeps), fruit cocktail, some medications, beverages, baked goods with red frosting.
Cancer links discovered: late 1980s. Banned in cosmetics: 1990. Still allowed in food: 1990–2025. Final ban in food: January 2025. That's 35 years of documented risk, ignored.
Again, state-level pressure — not federal initiative — forced the FDA's hand. Industry compliance deadline extends into 2027 for some products.
Chemically altered vegetable oils used to improve texture and extend shelf life in baked and fried foods.
Trans fats raise LDL ("bad") cholesterol, lower HDL ("good") cholesterol, and directly increase cardiovascular disease risk. The CDC estimated trans fats caused up to 20,000 heart attacks and 7,000 deaths per year in the US.
Margarine, shortening, pastries, cookies, crackers, fried fast food, microwave popcorn, frosting, non-dairy creamer.
Research linking trans fats to heart disease began in the 1990s. The FDA removed GRAS status in 2015, gave manufacturers until 2018 to comply — 20+ years after the science was clear.
The trans fat ban is held up as a public health win. But 20,000 preventable heart attacks per year for two decades while the industry lobbied is not a win — it's the cost of delay.
