The American Institute for Cancer emphasizes on its 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 in mind, making smart choices about what you eat can play a big role in reducing cancer risks. This article highlights everyday dietary adjustments that can enhance your well-being and help you steer clear of potentially carcinogenic foods.

1. Canned Foods with BPA Linings

Bisphenol-A (BPA) is a chemical commonly used in the lining of metal cans and certain plastic products. Research on animals and cells has linked BPA to various health concerns, including cancer, infertility, obesity, and diabetes. Unless explicitly labeled as **BPA-free**, most canned goods likely contain this compound. BPA is also found in some plastic packaging and dental sealants.

2. Processed & Smoked Meats

To preserve meats and maintain their color, food manufacturers use nitrates and nitrites. However, when these compounds are exposed to high heat, they can transform into **N-nitroso compounds**, which have been associated with an increased risk of cancer. Common examples of processed meats to limit or avoid include bacon, hot dogs, pepperoni, sausages, beef jerky, prosciutto, and salami.

3. Farm-Raised Fish

Farmed fish are often exposed to higher levels of pollutants, including **PCBs (polychlorinated biphenyls)**—a chemical linked to cancer. Because fish raised in farms are kept in crowded conditions, they are more prone to diseases, leading to increased antibiotic usage. Additionally, these fish are frequently treated with pesticides to manage parasites like sea lice.

4. Grilled Meats

When meat is cooked over an open flame, particularly on a grill, **polycyclic aromatic hydrocarbons (PAHs)** are formed. PAHs develop when fat drips onto the heat source, causing smoke that carries these harmful compounds onto the food. Over time, exposure to PAHs has been linked to an increased risk of cancer.

5. Hydrogenated Oils (Trans Fats)

Trans fats, found in hydrogenated oils, are artificially modified fats created to prolong shelf life and prevent spoilage. According to **the Harvard School of Public Health**, trans fats contribute to inflammation and immune system overactivity, raising the risk of heart disease, stroke, and diabetes. Moreover, these oils are processed with chemicals to alter their taste and eliminate unwanted odors.
