There are no proven ways to prevent cancer, but you can reduce your risk of getting it by avoiding the foods from the list bellow.
According to Cancer Research UK, 4 in 10 cancer cases can be prevented, largely through lifestyle diet changes.
These foods have been found to contribute to cancer and wreak havoc on your health. By avoiding them and switch to their healthier versions you can add quality and years to your life.
1. Microwave Popcorn
According to a recent study at the University of California, Perfluorooctanoic (PFOA) is linked to infertility in women. Numerous studies in lab animals and humans show that exposure to PFOA significantly increases the risk of kidney, bladder, liver, pancreas and testicular cancers.
If you enjoy finishing off a day by curling up and watching a movie with a bag of freshly nuked popcorn, it may be time to upgrade your night by going with a healthier popcorn option.
It’s easy enough to enjoy the taste of popcorn without the cancer risk by popping your own at home in ghee or coconut oil. This is actually a healthy snack as long as you’re using organic popcorn kernels. Avoid buying it at the movie theaters because the buttering agent they use is highly questionable, and could also be another cancer-former. Perfluorooctanoic acid is created during the microwave process from substances found on the inside of the bags.
2. Beef Jerky
Touted as a healthy go-anywhere protein-packed snack, most commercially produced beef jerky contains nitrites that have been proven to contribute to cancer.
Nitrites are found in other foods, but beef jerky has much more of them per ounce than many other foods.
When you want the convenience of beef jerky without the cancer risk you can make your own at home using organic, grass-fed ground beef rolled out thin using a rolling pin, and baked in the oven for hours at the lowest temperature. The nitrites in beef jerky have been linked to cancer, and they are added to give the jerky its color and also to preserve it and keep it fresh for months as it sits on store shelves.
3. Canned Foods
A 2011 Harvard study found that those who ate canned soup every day for five days had levels of BPA in their urine that were ten times those who had fresh soup. Another study from the same year found BPA in 71 out of 78 canned food samples, with concentrations varying drastically between food types and even within the same product. The Food and Drug Administration maintains that BPA is “safe at the current levels occurring in foods,” though scientists have linked low-dose, long-term exposure of the chemical to to breast cancer, changes in the reproductive system, and other health problems.

There’s a big debate over whether there’s enough BPAs in canned foods to cause cancer, and whether or not they’re transferred to the food the cans contain. Each side of the debate can produce studies that prove their case, so it’s hard to know which way to lean.
One way to sidestep the debate is to simply eat fresh or frozen food, or buy food in cans that specifically state that they are BPA-free. When there’s a controversy this big you can bet that it’s between advocates that rallying for consumer protection and Big Food that wants to maintain the status quo and their profit margins.
4. GMO Foods
The arms race is on when it comes to spraying crops with herbicides and pesticides, and these days many seeds have these toxic chemicals built right into them. This means that conventional produce is going to have these chemicals in it as an inherent substance, one that you can’t simply rinse off before eating.
Look for foods that are 100% organic, or contain the “Non-GMO Project Verified” seal on it to be sure that the food you’re getting is free of GMOs. Why get involved in the debate over the harmful effects of GMOs when you can simply avoid them and not worry about it anymore? Herbicides and pesticides that have been shown to cause cancer, among other diseases, are in GMO food from conventional produce to packaged goods.

Also, due to their diet, they have less of the healthy omega-3 that we think we are getting when we consume fish. Studies have also shown that farmed salmon contain high levels of PCB’s, mercury, and cancer causing dioxins. Avoid farmed salmon and buy it canned or look for labels in your market that state the fish you are buying is wild sockeye salmon.
6. Coca Cola/Pepsi
Before you enjoy that refreshing cola you may want to stop to consider what’s in it. In order to give it the distinctive brown color that shoppers have come to expect, cola manufacturers have been adding in a dye that contains a chemical that’s been found to cause cancer.
There’s also High Fructose Corn Syrup which will help feed any cancer cells you currently have. It’s best not to wait around for the food industry to find a replacement for this dye, now that consumers are on to them. Avoid drinking cola and as an added you should see a drop in your weight thanks to no more High Fructose Corn Syrup and spikes to your blood sugar levels. The cancer causing agent is 4-MI (4-methylimidazole) is what gives cola its classic caramel color, and is also directly linked to cancer in thousands of individual cases.

Although sodas are not a direct cause of ulcers, they are known to irritate and make those with ulcers have more pain. Sodas also contain artificial colorings and food chemicals like derivative 4-methylimidazole (4-MI); no wonder soda pop has been shown to cause cancer.
8. Diet Foods
The sad part about buying diet foods is that they often don’t help you lose weight, and could additionally be contributing to the likelihood of cancer. Obesity increases the chance of getting cancer, so it almost seems like you’re caught between a rock and a hard place when it comes to losing weight in a healthy way.
Many diet foods use artificial sweeteners to provide you the taste you’re looking for without having an effect on the number of sugar grams and calories. These artificial sweeteners are chemicals that have been created in a lab and have a toxic effect on the body. Aspartame is the most widely used artificial sweetener, has been linked to cancer for years, despite the FDA and other groups citing clinical trials that say there isn’t enough clear evidence to pull the toxin from the food supply.
9. Fried Snacks
Walk down any snack aisle in any grocery store and you’ll be bombarded by an array of snacks, each one packaged to look absolutely delicious, and each contributing to the formation of cancer.
The problem occurs during the frying process, and since these are pre-packaged snacks consumers often lose sight of the fact that they’ve been deep fried, much like french fries. The deep frying process that browns the snack and makes it crisp is the same process that forms cancer-causing substances that stay with the food. The Cancer-Causing Agent Glycidamide created by the metabolizing of Acrylamide, a substance produced from frying foods at high temperatures, is theorized as the cancer-causer for many snacks sold in stores today.
10. Hydrogenated oils
All hydrogenated oils are vegetable oils. Vegetable oils cannot be extracted naturally like butter is, vegetable oils must be chemically removed from their source, and then they are changed to be more acceptable to consumers. They are frequently deodorized and colored to look appealing.
All vegetable oils contain high levels of Omega–6 fatty acids. An excess of Omega- 6 fatty acids cause health problems, such as heart disease and in increase in various cancers, especially skin cancer. You need a good balance of both Omega 3 and Omega 6. Try to get plenty of Omega 3 every day. You can do this in the form of supplements and grass fed meats, also fatty fish such as salmon and mackerel are a very good source of Omega 3.
Hydrogenated oils are used to preserve processed foods and keep them looking appealing for a long as possible. Hydrogenated oils influence our cell membranes’ structure and flexibility, which is linked to cancer.
