Eat These Foods To Fight Off And Prevent Cancer

Cancer is a huge problem worldwide. It's one of the leading causes of death in America. In 2018 alone, over 1.7 million people were diagnosed with cancer. Thirty-five percent of all people who are diagnosed with cancer will end up dying from the disease. While we have come a long way, we haven't quite conquered cancer yet.

There are some steps you can take in your personal life to reduce the risk of developing cancer. A lot of cancers develop due to genetic factors, but environmental factors, including diet, can play a role as well. These scientifically-backed foods all fight and prevent cancer in different ways.

Blueberries Are Full Of Antioxidants

Blueberries are sometimes called a superfood, and they got that name for a reason. Blueberries contain more antioxidants than most other fruits. In a study published in Pathology & Oncology Research, blueberry extract improved radiation therapy. The researchers explain that blueberry extract reduces cancer cell growth. By itself, blueberries killed 25% of cancer cells before they developed into tumors.

Blueberries' flavonoids are anti-inflammatory, antioxidant, and antibacterial. All of these help your body defend itself against cancer.

While there is no evidence that tea cures cancer, there is some evidence that it may help prevent cancer. According to the National Cancer Institute, tea's antioxidants may stall cancerous growth. In animal studies, tea catechins prohibited cancer cells from invading the body.

ADVERTISEMENT

The type of tea you drink largely depends on personal preference. Black tea contains more antioxidants than green tea, but fewer catechins. Green tea offers more catechins and less caffeine than black tea. Remember that drinking tea isn't guaranteeing that you won't get cancer, but it will supply you with healthy nutrients.

Beans are a protein-rich food that may prevent cancer growth. Believe it or not, its ability partially comes from its high fiber content. During a 2012 study published in PLoS One, researchers concluded that high fiber intake may stop colorectal cancer. At least two other studies have backed up this claim.

ADVERTISEMENT

How many beans should you eat? During a study in Nutrition and Cancer, rats who ate black beans a couple of times a week had 75% fewer colon cancer cells. In 2010, the U.S. Department of Health & Human Service's Dietary Guidelines for Americans said that people should consume three cups of beans per week.

Despite being high in calories, olive oil contains healthy fats that protect your body. In Lipids in Health and Disease, researchers reviewed 19 studies about olive oil with over 13,800 patients. They concluded that those who consumed more olive oil had a lower chance of developing breast and digestive cancer.

ADVERTISEMENT

Research in a 2019 issue of PLoS One indicated that certain olive oils work better than others. Extra virgin olive oil zaps cancer cells, while non-extra virgin olive oils have no effect. High-quality olive oils contain oleocanthal, the ingredient responsible for preventing cancerous growth.

Tomatoes get their red color from a compound called lycopene. This same compound fights cancer. Better yet, consuming cooked or canned tomatoes does not change this effect. According to a 2013 review of 17 studies, consuming plain lycopene, raw tomatoes, or cooked tomatoes reduces your risk of prostate cancer.

ADVERTISEMENT

In particular, tomato sauce acts as a cancer-fighting agent. Published in the Journal of the National Cancer Institute, a 2002 study observed that eating more tomato sauce helps guard your cells against prostate cancer. Remember that these studies don't account for other factors, such as a healthy diet or exercise.

You may have heard the theory that soybeans raise estrogen levels and cause breast cancer. However, the research doesn't support this. The largest study on this topic, the Shanghai Women's Health Study, concluded the opposite. Out of 72,223 women who consumed soy, 22% had a lower risk of breast cancer and 47% had a smaller risk of premenopausal breast cancer.

Legumes are seeds or fruit from a legume plant that are high in proteins and fiber. According to a 2009 study, the more legumes you eat, the less risk you have of developing cancer. The study connected legumes with several cancers, including stomach, kidney, and digestive cancers.

ADVERTISEMENT

The research, published in Cancer Causes & Control, mentioned that several previous studies had confirmed this case. The reason is likely the resistant starch in legumes. When this starch meets gut bacteria, it ferments and produces other compounds. These compounds are thought to fight against cancer.

Sterols are substances that naturally appear in certain fruits, vegetables, legumes, and seeds. They have powerful cholesterol-lowering abilities. During a 2013 study in the journal Nutrients, researchers reported that sterols lower LDL cholesterol. This is the "bad" cholesterol that leads to various diseases.

ADVERTISEMENT

According to the research, plant sterols may prevent the formation of breast and estrogen cancer. Seventh-Day Adventists, who have a lower risk of cancer than most of the population, eat a diet rich in sterols. Foods with high plant sterols include vegetables, fruits, whole grains, vegetable oils, and sunflower seeds.

Citrus fruits such as oranges and lemons may guard you against cancer. According to a review of nine studies in the journal Pancreas, citrus fruits reduce the risk of pancreatic cancer. In 2010, another large study suggested that citrus fruit lowers the risk of digestive and upper respiratory cancers.

ADVERTISEMENT

You don't need a ton of citrus to see the results, either. Eating just three servings of citrus per week lessens your risk of stomach cancer by 28%, according to a 2008 study in Gastric Cancer. Just a few servings of margarine or lemon water will do wonders for your health.

With a survival rate of just 19%, esophageal cancer is one of the most dangerous cancers out there. Fortunately, 2011 research suggests that strawberries could prevent this disease. Scientists from the University of Ohio tested freeze-dried strawberries on 36 people. The fruits slowed down cancer growth in most participants.

ADVERTISEMENT

Strawberries offer a wide range of cancer-fighting flavonoids. One is the famous ellagic acid that's also found in raspberries. During the study, researchers noted that freeze-dried strawberries supplied more nutrients than fresh strawberries. The participants only ate two ounces a day to receive benefits.

Parsley offers unique flavonoids and chemicals that may reduce cancer. One flavonoid, myricetin, has killed colon cancer and skin cancer cells in many studies. With 100 grams of myricetin, parsley has the highest myricetin concentration of any herb.

ADVERTISEMENT

Another flavonoid, called apigenin, suppressed tumor formation during a study in BMC Cell & Bioscience. This plant nutrient has several functions. It prevents blood vessels from feeding cancer cells and improves chemotherapy. In particular, apigenin guards against mesothelioma cancer that creates tumors in the lungs, heart, and abdomen.

In 2009, a Chinese study demonstrated that people who ate watermelon, cantaloupes, and papayas had a lower chance of getting breast cancer. The American Institute for Cancer Research recommends watermelon and other melons to combat cancer. What makes them so special? It's a phytochemical called lycopene.

ADVERTISEMENT

Lycopene is related to beta-carotene, the compound that creates vitamin A. Lycopene is an antioxidant that protects normal cells from cancerous mutation. According to the EXCLI Journal, lycopene is reported to inhibit colon, prostate, and ovarian cancers.

In 2017, researchers from the University of Guelph noted that onions eliminate cancer cells. More specifically, onions "trick" cancer cells into undergoing cell death. Anthocyanin, the compound that gives onions their color, does this effectively. The redder the onion, the more it'll ward off cancer.

ADVERTISEMENT

But the best recipe combines onion with garlic. A study in 2019 suggests that allium vegetables--onions, garlic, chives, and shallots--can hinder the development of cancer. Participants who consumed high amounts of allium vegetables were 79% less likely to develop colorectal cancer.

The body has a natural protein that suppresses tumors. It's called PTEN, and researchers have studied how to create more for a long time. One way to receive PTEN is to eat cruciferous vegetables such as kale. With its high amount of antioxidants, kale stabilizes cell growth to slow tumor growth.

ADVERTISEMENT

To be clear, Harvard researchers do not suggest that eating kale will stop tumors. You'd have to eat six pounds a day to have the same effect as the cancer-fighting compound I3C. But if you want to potentially prevent cancer, consider eating more kale.

Because sugar feeds every cell in the body, it's imperative to a healthy diet. This fact led to the assumption that eating less sugar "starves cancer." While that has some truth, sugar alone won't cause cancer. The American Institute for Cancer Research asserts that there is "an indirect link" between indulging on candy and getting cancer.

ADVERTISEMENT

Yet, over-indulging on sugar may result in obesity, which is a cancer risk. The CEO of Cancer Council Australia, Professor Sanchia Aranda, announced that at least 3% of cancers stem from obesity. Too much sugar may increase the risk for ten different cancers, including breast, bowel, and liver cancer.

In 2018, the FDA banned seven artificial flavors. This decision stemmed from a study by the US Department of Health's study on these flavors. Through two animal tests, the researchers determined that these additives could cause cancer in high amounts. Scientists found the flavors in ice cream, candy, carbonated drinks, gum, and baked goods.

While looking into their diets, they pinpointed high-glycemic foods--ones that are starchy and sugary, such as bagels. Those who frequently ate high-glycemic foods were 49% more likely to develop lung cancer.

ADVERTISEMENT

Although the study included non-smokers, it did not take into account other conditions such as diabetes, hypertension, or heart disease. One of the researchers, Dr. Xifeng Wu, added that smoking is still more harmful than carbs. If there's a takeaway, it's this: diet has little impact on lung cancer as a whole.

Do grilled meats pose a cancer risk? The research says: possibly. According to the National Capital Poison Center, studies have found that when fat drips onto coals, it produces polycyclic aromatic hydrocarbons (PAHs). These may alter a person's DNA and have been linked to skin, bladder, and lung cancer.

ADVERTISEMENT

Most studies were laboratory-confined until 2016 when a study in Analytical Chemistry connected heterocyclic aromatic amines (HAAs) from cooked meat to prostate cancer in humans. However, the risk is still small. According to biochemical toxicologist Robert Turesky, you can avoid the risk by grilling less often and cutting off the charred bits.

Yes, milk is healthy. But consuming high intakes of dairy products has been linked to cancer, because of milk's hormone and fat content. For instance, a review of 32 studies in the American Journal of Clinical Nutrition connected a high amount of dairy to prostate cancer. This was backed by the Journal of the American College of Nutrition.

Prostate isn't the only cancer influenced by dairy. In 2014, researchers followed over 22,000 lactose intolerant individuals to record dairy's impact on health. They reported that lactose-intolerant people have a lower chance of contracting breast, lung, and ovarian cancers. You don't have to remove milk from your diet, but don't overdo it, either.

If you like crispy toast, you're not alone. But the Food Standards Agency advises against toasting your bread for too long. Why? It's because it produces the same chemical as frying potatoes: acrylamide. The carcinogenic chemical appears when sugary starches are cooked rapidly at high temperatures.

However, experts debate over whether acrylamide is enough to pose a huge danger. David Spiegelhalter, a professor at Cambridge University, said that you would have to eat 160 times more bread than the mice in studies to have a high risk.

In the early 2000s, french fry companies ran into several lawsuits. That's because researchers found the chemical acrylamide, which promoted cancer in animals. This research was backed up in a 2019 study published in Genome Research. During that study, 30% of the tumors analyzed linked back to acrylamide.

Although acrylamide has been known for a long time, some students did not find the link between that and cancer. Kathryn Wilson, an epidemiologist at Harvard, told NPR that acrylamide does not need to be a priority in health. And it's certainly not the least healthy part of french fries.

In 2012, a study came out that claimed genetically modified corn could promote cancer, and it was quickly retracted by the journal Food and Chemical Toxicology. Why? Because the study itself was flawed. According to Scientific American, the data was incorrectly written, some numbers were faked, and there was a clear bias from the authors.

Still, the study raised questions over whether corn carries carcinogens. In 2018, research from UNAM's Biology Institute noted that processed corn--usually found in tortillas--might have carcinogens. In particular, Mexico's corn contained some aflatoxins, which appears in some cancer tumors. The scientists claimed that eating antioxidant-rich food can counter this effect.

Beyond the acrylamide, there's another risk of eating too much bread. In particular, white bread contains sugars and starches that inflame the body. According to 2006 research in the International Journal of Cancer, eating five slices per day doubles a person's chances of kidney cancer.

White bread has demonstrated a higher risk than most other processed grains. In 2013, a study in Annals of Oncology noted that eating white bread poses a higher risk of colorectal cancer than pasta. That's another reason to swap white bread with wheat.

Ultra-processed foods, such as instant ramen and chicken nuggets, have contributed to obesity for decades. But in 2018, researchers found another risk in these foods other than their nutritional value. In The BMJ, a study reported that high amounts of processed food result in a 12% greater chance of ovarian and breast cancer.

Analyzed foods included packaged baked foods, processed meatballs, and frozen meals. Less-processed foods like pasta and cheese did not have this effect. French researcher and lead author Bernard Srour added that eating fresh foods lowers your risk of cancer.
