The number of people being diagnosed with cancer appears to be steadily rising. As a result, it has become more important to take note of the factors that could be contributing to the disease, including the added amount of chemicals and pollutants surrounding us. Although more studies are needed to know for sure, certain foods can help decrease cancer risk. Similarly, some foods can increase the risk of developing different cancers.

Refined sugar
Excessive intake of refined sugar is a primary cause of many common lifestyle disorders. It is also associated with an increased possibility of cancer. Some foods with refined sugar that can increase cancer risk are breakfast cereals and processed and packaged foods.

Processed meat
Processed meats like sausages, pepperoni, and hot dogs are a source of harmful compounds. Research suggests the regular intake of these cured meats considerably increases cancer risk. A daily intake of one and a half ounces of processed meat can increase rectal cancer risk by as much as 18%. If complete elimination is not an option, adding nitrite and nitrate-free meats to meals is advisable.

Chips
Salt is a potential carcinogen, which means it can increase cancer risk, especially if added excessively to meals. Chips, potato fries, and packaged foods are a few salty items to avoid. Besides increasing cancer risk, these contribute to inflammation in the body owing to a high quantity of salt.

Hydrogenated oil
Hydrogenated oil is a food associated with multiple health concerns. It can contribute to heart conditions, increase blood cholesterol levels, and even aggravate inflammation. Further, hydrogenated oils are associated with cell damage and increased inflammatory levels, both of which contribute to cancer risk.

Red meat
Despite being a healthy protein source, red meat is a food that can increase cancer risk. It releases carcinogenic chemicals, mainly because of the preparation method used. Red meat can be swapped for fish and poultry for better health benefits.

Bread
Bread is usually produced in massive quantities. Brominated flour is a primary ingredient used in the process, and the packaging could also state potassium bromate as one of its ingredients. Both of these have been found to be potential carcinogens.
