7. Hydrogenated oils
All hydrogenated oils are vegetable oils. The problem with vegetable oils is that they cannot be extracted naturally, like butter is, but must be chemically removed from their source, and then changed to be more acceptable to consumers. These oils are frequently deodorized and colored to make them appealing.
The second problem is that all vegetable oils contain high levels of Omega–6 fatty acids. An excess of Omega-6 fatty acids causes health problems such as inflammation, clogging of blood vessels, heart disease and increase in various cancers, especially skin cancer. You need a good balance of both Omega-3 and Omega-6, but studies show that diets rich in Omega-3 are very important for the normal functioning of your body and for disease prevention. You can add Omega-3 in your diet in the form of supplements or even better, fatty fish such as salmon, mackerel, herring and sardines.
Hydrogenated oils are commonly used to preserve processed foods and keep them looking appealing for longer periods of time. Hydrogenated oils influence your cell membranes’ structure and flexibility, which is linked to cancer.
8. Foods that are highly salted, pickled, or smoked
Foods that are cured by use of nitrates which act as preservatives as well as adding color to meat. Although nitrates do not cause cancer in and of themselves, under certain conditions these chemicals change inside the body into N-nitroso composites, which are associated with a greater risk of developing cancers.
Smoked foods such as meat or nuts cause these food items to absorb considerable amounts of the tar (a known carcinogen) that smoke produces. Meats such as bacon, sausage, bologna, and salami are high in fat and salt. Pickled foods are also very high in salts.
There is overwhelming evidence that eating these types of foods greatly increases the risk of colorectal cancer and higher rates of stomach cancer. The noted rates of stomach cancer are much greater in places where a traditional diet contains many foods that are highly salted, and/or smoked.
