16 cancer causing foods: What THEY don’t want you to know

8 Comments

Oh Natural News with your fear mongering. Here’s the truth about the 16 foods you say cause cancer.

  1. Canned tomatoes. According to the article, it’s not just canned tomatoes, it’s any canned foods. Although, canned tomatoes are allegedly worse because of their high acidity. It’s not the tomatoes per se, it’s the BPA that leaches from the lining of the can.

TRUTH: We don’t know if BPA causes cancer or not. We know that it’s an endocrine disruptor and it may cause cancer but we don’t know for certain that it does.

Some canned goods are available in cans with BPA-free lining. Although rumour has it, what ever’s in the lining of those may be just as bad as the BPA one. You can also buy some brands of tomatoes in glass jars, or just go for fresh if you’re truly concerned. I would never want to discourage anyone from consuming vegetables.

2. Soda pop. They take a convoluted route to cancer causation by saying that soda increases the risk of reflux which can cause ulcers which are linked to an increased risk of cancer.

TRUTH: There are so many good reasons not to drink pop; tooth decay, weight gain, type 2 diabetes, but cancer’s probably not one of them. Even the article talks about other health problems correlated with (i.e. not necessarily caused by) soda consumption. So, even if pop doesn’t cause cancer it’s still advisable to minimize your consumption of it.

3. Farmed salmon. Farmed salmon often contains sea lice and are raised in confined contaminated conditions.

TRUTH: This is statement is true but has nothing to do with cancer. There is no link to farmed salmon causing cancer. There are also some clean humane salmon farms. As with anything, if you’re concerned about the conditions in which your food was raised/grown, get to know your farmer.

4. Processed meats. These contain preservatives that may cause cancer. Smoked meat contains tar from the smoking process that may cause cancer.

TRUTH: This one is true. However, it doesn’t mean that your will get cancer if you eat processed meat. It just means that the more processed meat you consume the greater your risk of developing cancer in comparison to someone who never eats processed meat. It doesn’t mean that you should never consume processed meat but you should definitely consume it less often than every day. A safe amount has not been set so you’re kind of on your own to decide how often you want to eat processed meat. I’d try to limit it to no more than once a month.

5. Microwave popcorn. A chemical used to line the bag has been linked to cancer. Also the GMO popcorn kernels may cause cancer.

TRUTH: The GMO thing is bogus but the bag liner is legit (see above note re: risk from eating processed meat). What are you doing eating microwave popcorn every day anyway? How about some variety? Have popcorn occasionally but when you do, make air popped or stovetop or even use the brown paper bag method.

6. Potato chips. Cooking potato chips at a high temperature creates acrylamide which is a known carcinogen.

TRUTH: Sniff. Unfortunately, this is true (again, that whole increased risk thing applies; eating potato chips occasionally does not mean you’re guaranteed to get cancer). You can make your own or make home made kale chips instead. Or, just eat them once in a while as a treat. You shouldn’t be eating them on the daily anyway.

7. Hydrogenated oils. “Hydrogenated oils influence our cell membranes’ structure and flexibility, which is linked to cancer.”

TRUTH: Partially hydrogenated oils are bad. Partial hydrogenation creates trans-fats but the harm from consuming them is an increased risk of heart disease and stroke, not cancer.

8. Foods that are highly salted, pickled, or smoked. “There is overwhelming evidence that eating these types of foods greatly increases the risk of colorectal cancer and higher rates of stomach cancer.”

TRUTH: Well, the preservative and smoked issue was covered under number four. Little bit of overlap here. Too much salt can lead to hypertension and heart disease. Again, not related to cancer risk.

9. Highly processed white flours. White flour is bleached with chlorine gas. White flour increases blood sugar which feeds tumour cells.

TRUTH: Bleached flour is usually whitened using peroxide, although some flours use chlorine gas. Did you know that chlorine is used to kill pathogens in drinking water and it’s one of the components of table salt (sodium + chlorine)? Not a significant cancer risk. Even so, you can always get unbleached flour.

I don’t know what minimally processed white flours would be. Flour is flour. You gotta process grain to get it.

It is better to consume complex carbohydrates to obtain more nutrients. However, eating a croissant isn’t going to increase your cancer risk. Glucose is fuel for all of your cells, not just cancer cells. Cutting out white flour won’t prevent or cure cancer.

10. GMOs. Just read the section yourself. It’s too hard to tease out anything from this convoluted web.

TRUTH: I think that there are many risks associated with genetic modification. Primarily to biodiversity and the environment. It’s unlikely that cancer is one of them (although pesticides used to treat GM crops, and other crops, quite likely do cause cancer). This whole section is pretty misinformed bullshit.

There are very few GMO crops in the US at the moment (and despite what the article says, they have been approved by the FDA). If you are concerned about GM then try to buy organic versions of common GM crops.

11. Refined sugars. (see number 9)

12. Artificial sweeteners. “There is mounting evidence that the chemicals that make up these sweeteners, especially aspartame, break down in the body into a deadly toxin called DKP. When your stomach processes this chemical, it in turn produces chemicals that can cause cancer, especially brain tumors.”

TRUTH: Artificial sweeteners have been proven safe in MANY MANY studies. That being said, they may affect your perception of sweetness and there’s always the possibility that there is some other harm that they’re causing. I’m of the opinion that they taste weird and you’re probably better off having a little of the real thing (yes, sugar, honey, molasses, maple syrup…).

13. Diet anything. “All “diet” food is chemically processed and made from super refined ingredients, excessive sodium levels, as well as artificial colors and flavors to make it taste good.”

TRUTH: I’m not a fan of “diet” foods because it’s better to have minimally processed whole foods and fat. However, there is no evidence that “diet” foods cause cancer. Frustration and hunger maybe, but not cancer.

14. Alcohol. Alcohol use is the second leading cause of cancer, right behind tobacco use.”

TRUTH: Yes. This is true. Alcohol is a toxin. However, there are also heart health benefit associated with moderate alcohol consumption (i.e. approximately one drink a day for women and 1-2 a day per men). Pick your risk factor.

15. Red meat. Increases cancer risk; especially colorectal.

TRUTH: Yes, there is an increased correlation between red meat consumption and cancer diagnosis. However, it’s a very slight risk. As the article, surprisingly rationally suggests, you can still enjoy an occasional steak, it just shouldn’t be an every day food.

16. Non-organic fruits. The pesticides on them are toxic.

TRUTH: No mention of cancer here (just had to point that out). Still, many pesticides are likely harmful to humans and while some can be removed by washing, not all can. The thing is, you’ll find pesticides on organic fruit too, maybe in smaller quantities but some nevertheless. The health benefits you reap from eating fruit are likely greater than any cancer risk or other health risks the pesticides on them may pose.

The ultimate truth: We live in a carcinogenic environment. There are many things that we come in contact with on a regular basis that may cause cancer. Inciting fear in people about common foods is not going to help anyone avoid cancer. Continue to make mindful food and lifestyle choices and hope for the best. It’s all any of us can do.

  3. I had no idea that canned foods could cause cancer. I definitely would be interested in finding canned foods that had BPA-free lining. However, how can I know whether or not the can has BPA? http://cmnact.com/

    • There is no definitive evidence that the BPA in the lining used for canned foods causes cancer. It may, or it may not. In North America, some brands (such as Eden Organics) don’t use BPA in the lining. Best to check with the manufacturer if it doesn’t say on the label.
