The American Institute for Cancer states on their website, “Research has shown that most cancers can be prevented. Scientists now estimate that 60 percent to 70 percent of cancers are all preventable through currently available information and simple changes in diet and lifestyle.”
With that encouraging statement in mind, this article addresses changes you can make in your day to day dietary lifestyle that will not only improve your health but help provide you with knowledge of some possibly carcinogenic foods to avoid to aid in your efforts of cancer prevention.
Potentially Carcinogenic Foods to Avoid
1. BPA Lined Cans
This ingredient found in hard plastics and resins is used to coat metal cans. Laboratory studies in cells and animals have linked BPA to cancer, infertility, diabetes, and obesity. Unless a canned item is labeled BPA free, it’s likely to contain bisphenol-A (BPA). BPA can also be found in numerous plastic products and dental composites.
2. Cured and Smoked Foods
Nitrates and nitrites act as preservatives to prevent food from spoiling, they also add color to meats. When cooked, nitrites and nitrates change into by-products called N-nitroso compounds, such as nitrosamines and nitrosamides. N-nitroso compounds are associated with an increased risk of cancer. Some examples of processed meats to avoid are bacon, sausages, hot dogs, pepperoni, prosciutto, beef jerky and salami.
3. Farmed Fish
According to Food and Water Watch, farmed fish contain higher levels of chemical pollutants than wild fish, including PCB’s, a known carcinogen. Due to overcrowding in fish farms, fish are more susceptible to disease, increasing the need to use antibiotics. They are also more susceptible to sea lice, which means they are also treated with pesticides.
4. Grilled Meat
Polycyclic aromatic hydrocarbons, or PAHs, are produced through certain types of combustion, such as the burning of coal or wood. An additional problem is created when fat from meat drips onto a fire, creating a flare up and smoke, this allows the PAHs to affix themselves to the food you’re cooking, increasing your risk for carcinogenic exposure.
5. Hydrogenated Oils
Hydrogenated oils, also known as trans- fats, are a man-made product. These oils have a chemical structure that has been altered to prevent the product from going rancid in order to increase their shelf life.
The Harvard School of Public Health notes that trans fats promote immune system over-activity and inflammation and are linked to heart disease, stroke, and diabetes, among other chronic diseases. In addition to being chemically extracted from their source, chemicals are also used to mask the odor and change the taste of the oil.
6. Microwave Popcorn
These bags are lined with Perfluoroalkyls, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) to prevent oil from soaking through the packaging. When heated, these chemicals leach into the popcorn; when ingested, they show up as blood contaminants.
PFOA has been associated with tumors in animal organs (liver, pancreas, testicles and mammary glands in rats), and increases in prostate cancer in PFOA plant workers.

7. Non-Organic Fruits & Vegetables
Conventionally grown crops are grown with pesticides, herbicides, and GMO seeds; pesticides, in particular, have been associated with an increased risk of cancer. To learn more about the hazards of eating conventionally grown food, read EWG’s 2015 “Shopper’s Guide to Pesticides in Produce”
8. Processed Foods
Cured meats tend to be high in nitrites and nitrates, preservatives that can, in large amounts, potentially increase your risk of stomach and other cancers. Processed foods are also typically full of white flours, sugars, oils, colors, flavorings and other unhealthy ingredients.
9. Refined Sugars
Researchers have found links between sugar and numerous issues, such as unhealthy levels of blood fats, low HDL levels, increased risk for heart disease, higher blood triglyceride levels, obesity, immune suppression, arthritis and a host of other ills. Cancer cells also thrive on sugar.
10. Soda/Sports Drinks
There is little to no nutritional value in drinking soda or sports drinks. These drinks contain high fructose corn syrup, sugar, dyes, brominated vegetable oil (a flame retardant), and aspartame, which has been linked to an increased risk of cancer.
