7 Cancer Causing Foods You Should Stop Eating

5

According to the World Health Organization, cancer is one of the leading causes of mortality worldwide. Around a third of cancer deaths are caused by five key lifestyle risks: alcohol use, tobacco use, lack of physical activity, high body mass index, and low fruit and vegetable intake. In addition, the Preventable Cancer Foundation says only five percent of cancers are hereditary, so lifestyle choices have an enormous impact on overall cancer risk.

All of this is good news. It means you have far more control over your chances of getting cancer than you might think. And while making sure you have an adequate intake of things like fruits and vegetables, there are also foods you should avoid to decrease your risk of developing cancer.

There have been countless studies attempting to link certain foods to an increased or decreased risk of cancer. Cancer.net says the connection between a specific food and cancer can be difficult to establish because there can be complicating factors, such as interactions between the different foods and drinks people consume, and how a food is prepared may influence its risk or benefits.

However, there are some foods you should steer clear of, just to be on the safe side.

1. Processed Meat

Processed meats include hot dogs, luncheon meats, bacon, sausages, and other meats that are cured, salted, smoked or preserved in some way (i.e. meats that aren’t sold ‘fresh’).

There is very strong evidence that processed meats are carcinogenic, according to the International Agency for Research on Cancer, and the consumption of processed meat is known to cause colorectal cancer – the higher the consumption, the higher the risk.

The mechanisms by which processed meat causes cancer is not yet understood, but may be related to N-nitroso compounds produced when heme (from hemoglobin) in the meat is broken down and generated by nitrate preservatives. N-nitroso compounds have been shown to damage cells that line the bowel.

2. Refined Sugar/Sodas

Too much refined sugar causes a range of responses in the body that may indirectly increase the risk of cancer.

Sugar causes insulin spikes, which may lead to increased fat storage, and excess body fat increases your risk of several different cancers, according to the American Cancer Society. Being overweight or obese is also a risk factor for type 2 diabetes, which has been associated with breast, colon, and pancreatic cancers. In addition, the American Diabetes Association says regular consumption of sugary drinks has been linked to type 2 diabetes.

A study on mice models, published in Cancer Research earlier this year, has shown dietary sugar intake has a direct impact on breast cancer development and metastasis.

3. GMOs

Genetically Modified Organisms (GMOs) have been at the center of food safety debates for years, and of the most controversial are the ‘Round Up Ready’ crops. These crops have been engineered to withstand large doses of glyphosate (the key ingredient in Monsanto’s herbicide Roundup), which means when you ingest food from a Roundup Ready crop, you’ll likely be getting a dose of the Roundup it’s been sprayed with too.

A study republished in Environmental Sciences Europe in 2014 (after a controversial retraction due to commercial pressure) compared the effects of feeding rats Roundup-tolerant GM maize (cultivated with or without Roundup) or given Roundup alone in drinking water. All developed significant health problems over a two-year period compared with controls. All treatment groups had higher rates of tumor development.

4. Microwave Popcorn

The popcorn’s not the problem, it’s the bag it comes in. Many microwave popcorn bags contain a chemical called perfluorooctanoic acid (PFOA). PFOA causes liver, testicular, and pancreatic tumors in rats and is associated with kidney and testicular cancer in people exposed to it in drinking water, due to chemical plant emissions.

5. Farmed Salmon

Farmed salmon are treated with a range of chemicals including fungicides and antibiotics and even artificial color to make their flesh appear more ‘salmon pink.’

A study of organic contaminants in farmed Atlantic salmon compared with wild Pacific salmon revealed the farmed salmon had elevated levels of dioxin and dioxin-like compounds, PCBs, pesticides, and other toxins, some of which are known to increase the risk of cancer. Scientists concluded that the risks of eating farmed Atlantic salmon outweighed the benefits, especially for children, and pregnant or nursing women.

6. Hydrogenated Oils

Hydrogenation is the process whereby hydrogen is used to convert unsaturated fat in liquid form to a solid form, which results in trans fats being produced. Hydrogenated oils are found in things like margarine, vegetable shortening, premade baked goods, and fried foods.

Trans fats have been linked to several diseases including cancer, diabetes, and stroke. A study of around 20,000 women showed increased levels of trans-monounsaturated fatty acids in the blood, presumably due to a high intake of processed foods, increased risk of invasive breast cancer.

7. Canned Foods

Bisphenol A (BPA) is found in some plastics and is used to line food cans. BPA is a synthetic estrogen, which disrupts the body’s natural hormones.

BPA has been shown to increase the risk of mammary cancers in animals, and a study published in 2014 found that BPA disrupts the genes defending against breast cancer growth. BPA has also been linked to prostate cancer and BPA levels in urine may help predict prostate cancer in men.

  1. Just put cheap popcorn in a cheap brown paper bag and put that in the microwave. Monitor so it doesn’t burn. Take it out and put a bit of olive oil, cheese powder and/or brewers yeast and spirulina powder on it. Delicious!

    • ALSO…just b/c you put your popcorn in a brown paper bag, it is not worth using your microwave…read about the radiation in your microwave..use your stove instead..just sayin

  2. This fails in everyday to understand how scientific method works.

    This goes beyond the normal bad understanding of correlation vs causation and literally makes huge assumptions that are completely unfounded, for example having one study on one type of genetically modified crop should not have the tittle don’t eat GMOs. a relevant example would be like saying red meat causes cancer (it doesn’t it increases risk) so stop eating all food! Also technically all food we eat is a GMO so again stop eating all food!

    Honestly this is so fundamentally flawed in every aspect of science that it is depressing and sheer fear mongering. Please either go and learn how science research works or never post regurgitated rubbish like this.

    • Typical black and white reductionist thinking, if its not 1000% correct it has no value right? arrogant moron. FYI excessive soda consumption does lead to type 2 diabetes. So right there it proves your wrong and your dismissive tone is just juvenile.
