A healthy diet can significantly lower cancer risk. The American Institute for Cancer Research states that “about one third of the most common US cancers are preventable through a healthy diet.” Avoiding certain foods may help reduce that risk.

**Processed meats** like sausages and bacon are linked to cancer and heart disease. Limiting them could “prevent premature deaths.”
**Cured and smoked foods** contain nitrites and nitrates, which can turn into carcinogens when cooked.
**Hydrogenated oils**, often found in processed snacks, may double the risk of breast cancer.
**Microwave popcorn** bags contain PFOA, a chemical associated with multiple cancers.
**BPA-lined cans**, used in packaging, can leach harmful chemicals linked to cancer and hormonal issues.

Other risky items include **sodas**, which are high in sugar and artificial ingredients, and **sugar** in general, which has been “linked to an increased risk of certain cancers.”
**GMOs** treated with herbicides may pose risks, though research is ongoing.

Choosing fresh, whole foods and reading labels can help reduce exposure to these harmful ingredients and support long-term health.
