Fried foods can increase stomach cramps, gas, pain, bloating, indigestion and even increase the risk of dangerous conditions such as inflammatory bowel disease, colon and prostate cancers.
According to the Mayo Clinic, fatty foods, including fried foods, some sauces and fatty meats can cause gas.
Stomach bloating and gassiness can be painful, annoying and sometimes embarrassing, but avoiding certain foods and changing diet is the most cost effective way to treat the condition.
One particular type of food to avoid is that fried in vegetable oil, such as french fries, fried chicken and doughnuts.
Deep frying can also activate carcinogens — a substance that causes cancer.
For example, starchy foods such as French fries can form a compound called acrylamide that is linked to several types of cancer.
By increasing the length of frying time and the re-use of oil, this type of toxic compounds in the food is increased.
A study has shown that eating deep-fried foods at least once a week increases the chance of prostate cancer significantly.
Professor Janet Stanford, study co-author, said:
“The link between prostate cancer and select deep-fried foods appeared to be limited to the highest level of consumption — defined in our study as more than once a week — which suggests that regular consumption of deep-fried foods confers particular risk for developing prostate cancer.”
Professor Stanford concluded:
“To the best of our knowledge, this is the first study to look at the association between intake of deep-fried food and risk of prostate cancer.”
A more recent study found that frying in vegetable oil or eating fried foods increases inflammation of the colon, worsens inflammatory bowel disease (IBD), including colitis and colon cancer.
Foods fried in vegetable oil appear to harm the lining of the gut and increase the risk of gut leakage, which can lead to bacteria from the gut spreading into the bloodstream.
The reason that fried foods cause inflammation in the human body is related to the oxidation of polyunsaturated fats in the cooking oils when they are heated.
Deep fried foods have also been associated with lung, head and neck, pancreas, esophagus, and breast cancers.
