Top 10 Cancer Causing Foods That You Must Avoid

Cancer is a broad term for a group of many related diseases that involve cells in a part of the body that grow out of control.

This abnormal cell growth has the potential to invade or spread to other parts of the body.There are more than 200 different types of cancer.

Cancer causes a huge number of deaths every year. Millions of people each year are diagnosed with different types of cancer, such as breast, skin, oral, colon, ovarian, bladder and other cancers.

Possible signs and symptoms of cancer include a new lump in the body, abnormal bleeding, unexplained weight loss, sudden change in bowel movements, frequent fevers or infections, fatigue, loss of appetite, shortness of breath and coughing. While these symptoms may indicate cancer, they can also occur due to other issues.

You can take measures to reduce your risk of developing cancer—quit smoking, drink in moderation, maintain a healthy body weight, reduce stress, get proper sleep and lead an active lifestyle.

In addition, eating healthy is important and you must eliminate cancer-causing foods from your diet. The most common culprits are processed foods containing carcinogens.

Here are the top 10 cancer-causing foods that you must avoid.

1. Microwave Popcorn


While watching a movie or television at home, many of us like to have popcorn. Pop a little bag in the microwave and a big bowl of tasty popcorn is ready. However, microwave popcorn puts you at a higher risk of cancer.

Conventional microwave popcorn bags contain a chemical called perfluorooctanoic acid (PFOA), which is highly toxic in nature.

In fact, several studies have found that people with workplace exposure to PFOA are at a higher risk of bladder and kidney cancers.

In addition, according to a 2009 study published in the Environmental Health Perspectives journal, PFOA can cause impaired fertility in women.

When it comes to ingredients, microwave popcorn has soybean oil (a GMO product) and various preservatives, such as propyl gallate.

If you love popcorn, make it in an air popper to avoid these health-related concerns.

2. Canned Tomatoes


Canned foods allow you to enjoy your favorite vegetables throughout the year. However, if you are concerned about your health, avoid canned food, especially canned tomatoes.

The cans used to pack tomatoes and other foods are lined with a product called bisphenol A (BPA), an endocrine disruptor that may mimic or disrupt hormones and increase the risks for breast cancer, prostate cancer, early puberty, metabolic disorders, infertility, and several other problems.

When it comes to canned foods, canned tomatoes are more harmful to your health due to their high acidity, which allows the BPA from the can lining to soak into the tomatoes easily.

Instead of canned tomatoes, try to use fresh organic tomatoes as much as possible. You can also buy diced or whole tomatoes packed in glass bottles.

3. Farmed Salmon


Most of us are aware of the health benefits of eating salmon and even enjoy this fish a few times a week. However, many people do not think about whether they are eating farmed or wild salmon.

Farmed salmon is nowhere near as healthy as wild salmon, and eating farmed salmon puts you at a higher risk of developing cancer.

A 2004 study published in Science Magazine revealed that farmed salmon has significantly higher levels of cancer-causing and other health-related contaminants, such as polychlorinated biphenyls (PCBs), dioxins and toxaphene as compared to wild salmon.

The study even concluded that eating more than one farmed salmon meal a month could pose unacceptable cancer risks.

Farmed salmon also contains high levels of mercury and flame retardants.

As a majority of the salmon served in restaurants and sold in grocery stores is farmed rather than wild, you must avoid ordering salmon when eating out.

When buying salmon, make sure it is labeled as wild. Wild salmon is more expensive than farmed, but it’s worth the extra cost.

4. Hydrogenated Oil


Hydrogenated oil is not extracted naturally like olive, soy or canola oil and hence is not good for your health. Chemically extracted from vegetables, hydrogenated oil is again chemically treated to change the smell and taste, as well as extend its shelf life. This type of oil is used to preserve processed foods.

Some amount of omega–6 fatty acids is good for your health. However, an excess like that found in hydrogenated oil influences the structure and flexibility of cell membranes. This in turn increases your cancer risk, especially for skin cancer.

Moreover, the trans fats in hydrogenated oil promote breast cancer, prostate cancer and colorectal cancer risk.

You must never cook with hydrogenated oil. Instead, use extra-virgin olive oil, extra-virgin coconut oil or palm oil.

5. Potato Chips


Children as well as adults like potato chips. To make potato chips crispy, they are deep-fried in temperatures above 120 degrees Celsius (248 degrees Fahrenheit).

This causes them to make a material called acrylamide, a well-known carcinogen found in cigarettes. According to a 2006 study published in the International Journal of Cancer, dietary acrylamide puts you at a higher risk of ovarian, prostate, digestive tract and breast cancers.

Potato chips are also high in fat and calories, which contribute to unhealthy weight gain, high cholesterol, high blood pressure and other health problems. Plus, they contain artificial flavors and numerous preservatives that are not good for your health.

Instead of buying potato chips from the market, make them at home using healthy oil like olive oil. You can also opt for baked potato chips or tortilla chips, which contain less fat and calories. You can also try baked apple or banana chips, which are much healthier than regular potato chips.

6. Genetically Modified Foods (GMOs)


Genetically modified organisms (GMOs) like corn, potatoes, grains and soybeans are extremely harmful to the body. Such food products are grown using harmful chemicals and, when consumed, can lead to immune system, brain and liver damage.

In fact, the chemicals used to grow these foods cause rapid tumor growth.

As the U.S. Food and Drug Administration has no testing procedures for GMO foods, you need to look for labels that state the food is GMO-free. Try to buy locally grown fruits, vegetables and grains as much as possible.

7. Refined and Artificial Sugars


Refined sugar, artificial sweeteners and fructose-rich sweeteners like high-fructose corn syrup are not good for your health. These products tend to rapidly spike insulin levels and feed the growth of cancer cells.

According to a 2006 study published in the American Society for Clinical Nutrition journal, high intake of sugar and sugar-sweetened foods increases the risk of pancreatic cancer.

Instead of using refined sugar or artificial sweeteners, you can try alternatives like honey, jaggery, blackstrap molasses, maple syrup or the herb stevia to sweeten any dish.

8. Refined White Flour


A common ingredient in processed foods is refined white flour. Refined flour contains excess carbohydrates that are not good for your health and even increase the risk of cancer. During the milling process, white flour is bleached with chlorine gas, which is highly toxic for the body.

In fact, studies have shown that excess carbohydrate intake increases the risk of breast cancer among women. In addition, white flour has a high-glycemic rate that rapidly raises blood sugar levels. A spike in blood sugar promotes cancer cell growth and spreading.

Instead of using refined white flour, try some healthier options like whole-wheat, almond, quinoa or barley flour. You can use these flours for baking or making breads.

9. Processed or Red Meat


Processed meats such as ham, sausage and bacon have chemicals and preservatives like sodium nitrates, which make them bad for your health. In addition, processed meat contains excessive salt, which is also not good for you.

In a 2008 study published in the Nutrition and Cancer journal, researchers found that processed meat intake might be involved in the etiology of colorectal cancer.

Along with processed meat, you must avoid excessive intake of red meat that can lead to higher risks of colon and prostate cancer.

To avoid the harmful effects of processed meat, try lean meat and cook your own food.

10. Pickled and Smoked Foods


Pickled and smoked foods are delicious but, at the same time, very harmful to the body. In fact, smoked meats that pick up tar from the smoking process cause extreme harm to your body. Plus, most pickled foods contain nitrates that turn into N-nitroso, which increases your risk of cancer.

Moreover, they contain preservatives to prolong shelf life, which can accumulate in your body over time. This can cause damage at the cellular level and lead to cancer and other diseases.

Smoked foods are high in fat and, when cooked at high temperatures, the nitrates are converted to nitrites, which is even more harmful to the body.

Try to avoid pickled and smoked foods as much as possible.
