Most Common Cancer Causing Foods

Janes Story

Jane had finished with chemotherapy about 1 year ago. Unfortunately, ever since having had completed with Chemotherapy, she has been left feeling extremely weak with severely low energy. She also continued to suffer from chronic depression and severe brain fog where she has been unable to think clearly or remember much, and for almost no apparent reason, would angry quite easily. To make matters worse, the full body aches and pains she felt while going through Chemotherapy has actually gotten worse.

Upon completion of Chemotherapy, there had been no mention to Jane of any type of special diet or nutritional plan designed for helping her feel better, nor was one provided for any type of prevention in mind. Thinking about how food and nutrition can play such a crucial role in our health, she thought that her doctor would surely know or would have recommend something to at least help her recover.

One day at a follow-up appointment, Jane turned to her Oncologist and asked “Hey doc, are there any specific foods I should avoid or focus on eating that will help me get to feeling better, as well as anything I should do or take to help me reduce my risks of having my cancer re-occur?” Her Oncologist politely responded, Unfortunately, what you are going through is
common and there’s not much you can do about it.  It’s normal, be patient and you will
eventually feel better. Supplements haven’t been found to help and are just a waste of money. I would recommend you focus on enjoying life as best as you can and eat what you want.”

Does this scenario sound familiar to you?

Fortunately, this is not the mindset of all Oncologists, unfortunately, I still hear this WAY TOO OFTEN.

Today, common sense and I are here to tell you, with 100% certainty, that Nutrition, our Food Choices, and Quality of Foods, beyond the shadow of a doubt, play a huge role in Cancer, Prevention and Repair.

Of course, there are many other variables and factors involved, but today we get to discover what I consider to be the top 12 cancer causing foods.

Healthy Food IS:

Two bowls of oatmeal and fruit

The best overall description I can give on healthy food and eating would be:

Anything grown or raised that has not been altered or tampered with by man.

Healthy Food Is NOT:

  • A Stew of Pesticides & Herbicides.
  • Genetically altered and sterile, requiring chemicals to grow.
  •  Artificially Refined, Processed, Colored, Preserved, Pasteurized, or
  • Homogenized.
  • Crinkly Packages like Chips, Cookies, Crackers, and More.
  • Ingredients You Can’t Pronounce.


Now that you have a general overview of what is a HEALTHY FOOD vs What is NOT A HEALTHY FOOD

Let’s read on to discover what I consider to be:   The Top 12 Most Cancer Causing Foods


The Top 12 Cancer Causing Foods:

Post Chemo Nutrition Infographic for Top 12 Cancer Causing Foods

1.  Soda Pop

Loaded with large amounts of sugar, artificial sweeteners, chemicals, and caramel coloring have all been linked to:

  • Acidifying the Body
  • Lowering the Immune System
  • Obesity
  • Insulin Resistance
  • Leptin Resistance
  • Diabetes
  • Heart Disease
  • Cancer
  • Gout

2. GMOs and Glyphosate

Genetically Modified Organisms and Weed Killer: These foods are exposed to a large array of different chemicals, many of which have never been thoroughly tested for safety.

Recent studies have found certain common herbicides to be linked to rapid tumor growths.

Chemicals are NEVER good for us!

Whether you want to believe they are necessary or just convenient, ultimately these chemically laden foods are toxic, unhealthy and contribute to the growth and spread of
cancerous cells.

I’m sure you have seen and heard all the attorney ads asking “have you used roundup and now
have cancer, contact us…”.

3. Farmed Fish

Grown in a toxic water environment full of PCBs, Pesticides, Herbicides, Flame Retardants and Antibiotics.

These toxins absorb into the fish that you would eat. Not to mention the food they usually eat is that of other sickly, diseased dead fish.

4.  Microwave Popcorn

yes, I said it…Yummy and convenient, microwave popcorn. Unfortunately, the bags are lined with PFOA (perfluorooctanoic acid) which has been found to be cancer causing, not to mention it is pretty much all GMO corn.

FYI - Teflon also contains high levels of PFOA.

5. Canned Foods

BPA (bisphenol A) forms the lining of many canned foods.

Acidic foods like tomatoes, tend to help leach this BPA out even more from the can and into your food.

BPA has been found to effect hormones and cancer and is best to avoid in our food supply.

6.  Artificial Sweeteners

Such as Aspartame, NutraSweet, Splenda, Sucralose, and more.

These are PURE CHEMICALS that have been potentially found to contribute to the cause of cancer and other serious health problems.

I won’t get into the details here because people really enjoy these low-calorie cheats, however I can tell you with 100% certainty that these man-made chemicals are very toxic, unhealthy and cancer causing.

Sometimes it is best to just go for real, raw, natural sugar.

7. Processed and Over Cooked Meats

Bacon, sausage, hot dogs, pepperoni, prosciutto, jerky and salami have all been found to contribute to the cause of many different forms of cancer.

Especially those higher in nitrates, nitrites and added preservatives.

Cooking meat over 300 degrees Fahrenheit has also been found to be a big contributor to cancer.

8. Refined White Flour

This one is more indirect in that it contributes more towards the development and production of systemic inflammation.
White flour has inflammatory gluten and is bleached using chemicals, often left void of any nutritional content.

Some of the additional dangers can be:

  • Fatty Liver Disease
  • Elevated Bad Cholesterol
  • High Blood Pressure
  • Obesity
  • Depression

9. Hydrogenated and Vegetable Oils

trans fats found in refined and deep-fried foods like chicken nuggets, french fries, potato chips, cooking oils and more have been found to chronic inflammation and cancer.

Some of these inflammatory oils can be very deceiving and made to look healthy. Some that I would not give to my worst enemy are:

  • Corn
  • Sunflower
  • Palm
  • Soy Bean
  • Canola

10. Sugar

Yes, sugar. I know I have seen many Oncologists tell their patients that sugar is
not proven to contribute to cause cancer. However simple math, common sense and much research has found that sugar really does have an effect, both directly and indirectly on contributing to both the cause and recurrence of many forms of cancers.

  • Cancerous cells consume much more sugar than healthy cells
  • Increases insulin production which fuels cancer.
  • Contributes to diabetes, which causes an increased risk of certain cancers.
  • Contributes to obesity - Increases risk of cancer.

11. Drinking Water

A large amount of our municipal drinking water is loaded with many
toxic minerals and heavy metals like lead as well as prescription medications. Plus, many other toxic, cancer causing chemicals like fluoride and chlorine is found in our water supply.

These chemicals have been found to form into other toxic chemicals called  trihalomethanes (THMs), which may contribute to human bladder cancer.

THMs have been shown to cause cancer in animals, linked to miscarriage and contribute to other pregnancy risks in women.

Don’t forget - we absorb these chemicals through our skin when we shower as well!

12. Food Additives

There are over 3000 food additives, most of which have never been tested for safety due to legislature being passed decades ago putting the responsibility to test for safety
on us, the public.

Often, when these chemicals do get tested, they are found to be cancerous. In fact, many countries have banned many chemicals that the US says is safe.

Bottom line, chemicals are usually bad, especially when ingested.


Never Stop Learning

Picture of books with an apple on top, colored pencils and blocks A, B, C.

Whether you are currently going through Radiation or Chemotherapy
Whether you are done with Radiation or Chemotherapy
Whether you are looking at Cancer Prevention
It is imperative that you Never Stop Learning!


Thank you very much for spending the time to read this report and taking a step towards
recovery and prevention.

Sometimes we must take matters into our own hands and learn what we can through a
commonsense approach.

I don’t feel it is wise to leave our food choices and decisions up to Doctors that have little to no training in the field of health and nutrition, especially when our lives depend on it.

Hopefully, by now you can see that our dietary choices affect us quite a bit.

Nature or God has given us some amazing tools designed for Health, Repair & Prevention.

It is up to you to decide if you want to choose what God has given us from Nature or accept the chemical additives and changes man has made for the sake of convenience. Either way, that is the beauty of America…Freedom of Choice!

Thank you and God Bless!
