5 foods that have maximum amount of cancer-causing acrylamide

Acrylamide might sound unfamiliar, but it’s found in many everyday foods. According to the U.S. Food and Drug Administration (FDA), acrylamide is a chemical that can form in some foods during high-temperature cooking processes like frying, roasting, and baking. It forms mainly in plant-based foods that are rich in starch, especially when cooked above 120°C (248°F). While research is ongoing, acrylamide is classified as a potential human carcinogen, and many health agencies suggest reducing exposure where possible.

A few small changes in how you cook can lower its formation without losing out on taste. Here are some common foods known to form higher levels of acrylamide and safer ways to enjoy them.

Potato chips, French fries, and other deep-fried snacks

are among the biggest culprits. Acrylamide forms when natural sugars in potatoes react with amino acids at high temperatures. The longer and darker the frying or baking, the higher the content. According to food safety studies, acrylamide levels in potato chips can range from 300 to over 2000 µg/kg, while French fries may range from 200 to 700 µg/kg. Boiling or air-frying, and skipping excessive crisping, can help bring the numbers down.

These are often baked at high temperatures and can contain not just acrylamide but also added preservatives and refined sugar. Studies show acrylamide levels in biscuits can range from 160 to 1000 µg/kg, depending on the ingredients and baking method. If you love a tea-time treat, consider lightly baked or homemade versions that use whole grain flours and less sugar.

The darker the toast, the more acrylamide it likely has. That deep brown colour signals high-temperature cooking, which increases the chemical’s formation. Lighter toasting significantly lowers the risk. Acrylamide levels in toasted bread can range from 50 to 500 µg/kg, with darker toasts leaning toward the upper end. Whole grain or multigrain breads, toasted gently, are safer and healthier options.

Acrylamide is formed during the roasting of coffee beans, especially in the initial stages. While you don’t have to give up your daily brew, moderation is key. Light to medium roasts often have less acrylamide compared to dark roasts. According to published data, brewed coffee can contain 5 to 20 µg/L, while instant coffee may contain 100 to 400 µg/kg in powdered form. It is also said that coffee is acidic and may irritate the stomach lining. It can lead to acid reflux, heartburn, or gastritis, especially on an empty stomach.

Corn flakes, wheat crisps, and other puffed cereals are often baked or toasted at high heat. This process creates acrylamide, especially in sugar-rich and overly browned cereals. Studies show that acrylamide levels in these products can range from 150 to 1200 µg/kg, depending on the brand and preparation method. Opting for traditional cooked grains like oats, poha, or daliya is usually a safer and wiser choice.
