8 Cancer-Causing Foods to Avoid

According to the American Institute for Cancer Research, about one-third of the most common cancers in the US can be prevented through a healthy diet. This highlights the need to avoid certain foods that have been linked to an increased risk of cancer. Here are eight foods you should limit or avoid altogether to reduce your risk:

  • Processed Meats
    Foods like bacon, sausages, and hot dogs have been linked to both cancer and cardiovascular disease. Limiting your intake of these meats can help prevent serious health issues, including premature death.
  • BPA-Lined Cans
    BPA is a chemical used in plastic and can linings, which has been associated with an increased risk of cancer and other health problems. Opt for BPA-free products to reduce your exposure.
  • Cured and Smoked Foods
    These foods contain nitrites and nitrates, which can form cancer-causing compounds, especially when cooked at high temperatures. Reducing your consumption of these foods may lower your cancer risk.
  • Microwave Popcorn
    The bags used for microwave popcorn often contain PFOA, a chemical linked to various types of cancer. Choosing air-popped popcorn is a healthier alternative.
  • Genetically Modified Organisms (GMOs)
    Some genetically modified foods are treated with herbicides that may increase cancer risk. Opting for organic, non-GMO products may help limit your exposure.
  • Sugar
    Diets high in sugar have been associated with an increased risk of certain cancers, particularly obesity-related cancers. Reducing your sugar intake can be beneficial for overall health.
  • Hydrogenated Oils
    Common in processed foods, hydrogenated oils have been linked to a doubled risk of breast cancer. Look for healthier alternatives like olive or coconut oil.
  • Sodas
    Loaded with sugar and artificial ingredients, sodas are linked to an increased risk of cancer, along with a variety of other health issues like obesity and diabetes. Cutting back on soda can reduce your cancer risk.
