Unfortunately, those who eat fast food a lot, that is several times a week, are more prone to contract cancer in the long term than those who avoid fast foods. One risk comes from the fact that some of the fast food snacks contain the potentially cancer-causing chemical acrylamide.
Smoky fast foods especially meats and nut dishes are rich in tar produced by the smoke, which is a known Carcinogen. Barbecue flavour is tremendously popular but may be a problem if taken often. Most of the smoky flavoured foods increase the risk of colorectal and stomach cancer, with a probability of developing other cancers also being high
Eating deep fried fast foods boosts your risk of prostate cancer, according to a new study from the Fred Hutchinson Cancer Research Center in Seattle. Researchers analyzed survey data from more than 3,000 men ages 35 to 74, and discovered that guys who reported eating French fries, fried chicken, fried fish, and/or fried doughnuts once or more a week had a 30- to 37-percent higher risk of prostate cancer.
The risk remained the same even after the researchers considered factors like age, race, family history, body-mass index, and prostate-specific antigen (PSA) levels. By comparison, men who had the lowest prostate cancer risk only ate fried foods less than once a month, while men with a more moderate risk ate fried foods one to three times a month.
