Fourth of February, World Cancer Day, may have passed, but right now is as good a time as any to better our understanding of this potentially fatal disease.
Many factors can increase one’s risk to cancer; weight, smoking, family history, diet, a sedentary lifestyle, to name a few. If you notice, most factors on this list are actually in your control—diet is one such factor
Add these 20 food allies to your diet in the fight against cancer. Besides having anti-cancer properties, some of these foods will help in your weight loss efforts too.
Carrots contain falcarinol, a substance that research has shown to lower the risk of cancer. According to a study, the rate of growth of isolated cancer cells reduced upon exposure to falcarinol.
To get this benefit from carrots however, they must be eaten raw and not cooked. A simple way is to use it as a garnish in salads or make a fruit juice with carrot as an ingredient.
Carrots are also rich in beta-carotene, which may help lower the risk of many cancers including prostate, bladder, breast, intestine, stomach, lung, mouth, and throat cancer.
2 Broccoli, Cauliflower, And Cabbage
Indole-3-carbinol is the common component in these three vegetables. A chemical component, indole-3-carbinol is used for the prevention of breast cancer. Studies show that it works by stemming the growth of breast cancer cells.
In addition to indole-3-carbinol, broccoli, particularly sprouts, contains the phytochemical sulforaphane (produced from glucoraphanin), which is believed to be helpful in the prevention of rectal and colon cancer. Tests have shown that these enzymes demonstrate an ability to inhibit tumor growth.
Berries are tasty and extremely healthy. They are particularly rich in antioxidants, pals who fight off free radicals in our bodies which damage cells. Chemical compounds found in berries also help keep cancer cells from spreading. If you are on an anti-cancer diet, berries are one food you must eat on a regular basis.
People who are at an increased risk of stomach cancer or colorectal cancer will benefit from eating garlic. This is because garlic has anti-bacterial effects against a particular bacterium found in the stomach and which is linked to stomach cancer: Helicobacter pylori.
Garlic is most useful as a cancer-preventive food when consumed raw or cooked. Garlic supplement, on the other hand, does not exhibit the same cancer-fighting qualities as raw or cooked garlic.
According to a study, the risk of stomach cancer dropped by half and risk of colorectal cancer dropped by two-thirds in people who ate raw or cooked garlic in comparison to people who did not eat or ate little garlic.
5 Pomegranate Juice
Like green tea, pomegranate is extremely rich in antioxidants too. Many scientists believe the antioxidants present in this fruit have strong anti-cancer properties.
Pomegranate juice, as well as its extract, is found to be beneficial against prostate cancer. In a study, scientists found that both the juice and extract of this fruit inhibits the growth of prostate cancer cells.
Coriolus Versicolor, Agaricus blazei Murill, shiitake, maitake, and reishi seem to strengthen the immunity and help in the fight against cancer.
All these mushroom varieties contain lentinan, a polysaccharide that helps strengthen our immune system. They are also a good source of lectin, a protein known to prevent cancerous cells from spreading.
A common spice in Asian dishes, turmeric has anticancer effects, according to several studies. Turmeric not only helps to rid cancer cells but also prevent them from multiplying.
Turmeric seems to be more effective against certain cancerous cells such as skin cancer, stomach cancer, bowel cancer, and breast cancer cells. The anticancer ability of turmeric is attributed to its one ingredient, curcumin.
According to a laboratory study conducted, the combined dosage of chemotherapy and curcumin killed more bowel cancer cells than chemotherapy alone.
Another study done on mice showed that curcumin helped in preventing breast cancer cells from spreading.
8 Pumpkin And Sunflower Seeds
A few years back, a study was published in the Journal Nutrition and Cancer which stated that these seeds have anti-cancer properties.
According to the study which involved 8,000 women in total (3,000 women had breast cancer and 5,000 did not), women who consumed pumpkin and sunflower seeds in high amounts along with soybeans had a lower risk of developing breast cancer after menopause.
Prostate cancer is the second most common cancer (the first being skin cancer) in American men, and worldwide, 1 in 8 men will be diagnosed with it once in their lifetime.
The good news is that tomatoes can reduce the risk of prostate cancer by 20 percent, according to a British study. To get this benefit, you just need to consume 10 servings of tomatoes per week.
The cancer-preventing effects of tomatoes are attributed to the chemical lycopene found in them. Lycopene is also available as a supplement, though health experts agree that it is best to get this antioxidant from natural foods instead of supplements.
10 Green Tea
A big part of the Asian diet, green tea has many ingredients with medicinal properties and which experts are still studying to understand how they affect our health. These ingredients include catechins, xanthine derivatives, epicatechin, and epigallocatechin-3-gallate.
Experts believe that these ingredients help protect against prostate cancer, pointing towards the significantly lower prostate cancer numbers in Asia which they attributed, to a large extent, to the consumption of green tea in comparison to the US.
A review has also been published by Chinese Medicine¸ stating that the risk of prostate cancer was lower in men who drank in excess of 5 cups of green tea on a daily basis.
11 Whole Grains
This recommendation comes from none other than the American Institute of Cancer Research. According to them, whole grains have many components that might reduce cancer risk, including antioxidants and fiber.
A large study involving no less than half a million participants revealed that eating more whole grains was linked to a reduced risk of colorectal cancer. Examples of whole grains include whole-wheat bread, brown rice, barley, and of course, oatmeal.
Several compounds like quercetin, triterpenoids, epicatechin, and anthocyanins found in apples are known to have antioxidant and anti-inflammatory properties. These are all helpful in reducing the risk of colorectal cancer.
From the cancer prevention perspective, apple peel is the most important as it contains as much as 80 percent of quercetin.
Apples also help to prevent other cancers like lungs and breast cancer.
Because of their family history, some women have a high risk of getting breast cancer later on in life. One way to prevent this is to change their nutritional habits, which could significantly negate their increased risk of breast cancer.
Fatty fish is one such food. Studies have shown that consumption of fatty fish helps to reduce the risk of breast cancer. In a study, researchers found that women who used fish oil supplement were 32 percent less likely to develop breast cancer 6 years later than women who did not consume fish oil supplement.
Fatty fish contain a lot of omega-3s, which experts believe decreases inflammation and consequently offers protection against breast cancer. Chronic inflammation in the breast is believed to encourage the development of breast cancer.
Apart from supplements, you can get more omega-3 fatty acids by consuming more mackerel, tuna, and salmon.
14 Brown Rice
A study published in Nutrition and Cancer states that the risk of colon polyps is 40 percent less in people who consumed one serving of brown rice per week. Experts believe this is because of the high fiber content of brown rice. A short-chain fatty acid present in fiber stops the growth of cancer cells. Brown rice is extremely fibrous—containing 3.5 g of fiber in a single cup.
Walnuts might help slow the growth of breast cancer. In a study conducted, some mice were fed the human equivalent of two ounces of walnut every day for 34 days while another group of mice was put on a walnut-free but calorie-equivalent diet. The growth rate of cancer was found to be fifty percent less in mice who were fed the walnuts than those who were not fed walnuts.
Apart from this, walnuts are in general a good source of antioxidants and omega-3 fat alpha-linolenic acid, both of which have strong anti-inflammatory properties. These two ingredients make walnuts an important anticancer food too.
Apart from breast cancer patients, walnuts are also recommended for men with prostate cancer.
16 Ground Flaxseed
Flaxseed is extremely beneficial for women at a high risk of breast cancer as well as for women diagnosed with breast cancer.
In a clinical trial, breast cancer patients who used flaxseed recorded a significant reduction in tumor growth after a few weeks. Flaxseeds contain lignans in extremely high quantities, which scientist believes have a strong anticancer mechanism.
In another study involving postmenopausal women diagnosed with breast cancer, researchers noted that a higher intake of lignan was linked with reduced risk of breast cancer mortality as well as reduced risk of overall mortality.
Mediterranean diet includes a liberal amount of citrus and people in this region have low rates of lung cancer, breast cancer, pancreatic cancer, cervical cancer, and rectal cancer. Many experts believe there is a correlation between citrus in the diet and risk of cancer.
Research shows that citrus fruits may indeed contain more anticancer agents than other foods. In fact, the National Cancer Institute rates oranges very high in the list of foods containing anticancer agents. Unfortunately, we usually do not consume the part of the orange that provides maximum anticancer benefits—orange peel.
Oranges contain a phytonutrient called limonene, which helps prevents cancer. Oranges, much like limes, lemons, and mandarins, contain a lot of limonene in the peel. The pulp of the fruit also contains limonene, but in significantly less amount than the peel.
According to a study published in the Journal of the National Cancer Institute in 2015, coffee might help protect against malignant melanoma, a common type of skin cancer.
Researchers found that people who on average drink four cups of coffee or more daily had a 20 percent lower risk of malignant melanoma than non-coffee drinkers.
19 Sweet Potatoes
Studies show that a diet that includes copious amounts of foods rich in beta-carotene, a potent antioxidant, has a lower risk of cancer, in particular, lung, stomach, and colon cancer. Beta-carotene is found in high amounts in leafy green vegetables and orange vegetables like carrots.
According to one study involving postmenopausal women, participants who ate large amounts of vegetables that include vitamin C, folate, fiber, and beta-carotene—for example, sweet potatoes—had fifty percent less chance of developing breast cancer.
Scientists at the University of Missouri found parsley to inhibit breast cancer cell growth in an animal study. In the study, apigenin (a bioflavonoid found in plenty in parsley) strengthened the animals’ resistance to fight against cancerous tumors.
Add a small amount of parsley to your food daily to obtain the same benefits.
