Dandelion green

Dandelion greens have many anticancer compounds, including alpha-carotene, alpha-lipoic acid, beta carotene, lutein, and zeaxanthin. Research published in the International Journal of Oncology found that a tea made from dandelion leaves decreased the growth of breast cancer cells, while a tea made from the roots of the dandelion plant blocked the ability of cancer cells to invade healthy breast or prostate tissue.

Ginger root and ginger powder in the bowl

Gingerroot has significant anticancer and tumour-destroying properties. According to researchers, ginger’s anticancer potential is due to several natural compounds, including gingerol, paradol, shogaol, and zerumbone. Research in the International Journal of Preventive Medicine found that ginger may help treat breast, colorectal, gastric, liver, prostate, and skin cancers.

Microgreens are truly small but powerful. In a study published in the Journal of Agriculture and Food Chemistry, researchers found that microgreens contained up to 40 times as many nutrients as their full-grown vegetable counterparts. The miniature leaves can contain up to 40 times more anticancer nutrients such as vitamin C, carotenoids (beta carotene, lutein, and zeaxanthin), and vitamin E than their mature counterparts.

5. Miso

In a study published in Hiroshima, Japan, researchers assessed the long-term effects of miso consumption on animals with lung cancer and found that those who were fed miso that had been fermented over many months experienced a significant reduction in the number of lung tumours and adenocarcinomas—a specific form of lung and glandular cancer. They concluded that dietary supplementation with long-term fermented miso could exert cancer-preventive effects on lung cancer, while other research demonstrates miso’s protective effect against breast cancer.

6. Parsley

A study in the Journal of the Science of Food and Agriculture found that parsley acts as an antioxidant that destroys free radicals before they damage cells, protects DNA from damage that can lead to cancer or other diseases, and inhibits the proliferation and migration of cancer cells in the body.

Not only is sauerkraut made from cabbage, one of the best anticancer foods, but research published in the journal Nature Communications found that probiotics, such as those found in naturally fermented sauerkraut with live cultures, may help prevent cancer. They may also provide help in treating cancer. During the fermentation process, nutrients in cabbage are transformed into powerful anticancer compounds known as isothiocyanates.

While you may think of turmeric as a delicious curry ingredient or brain health booster, its main compound curcumin shows promise against prostate and colon cancer as well. In a study published in the medical journal Precision Oncology, researchers found that curcumin starved and shrunk prostate cancer tumours. Other research found that it may also reduce colon cancer risk.


Herbs and supplements for more support

When your diet is lacking in nutrients or if you just want to take extra precautionary measures against cancer, you’ll want to consider the following supplements.

Green tea 

Epigallocatechin gallate (EGCG) found in green tea demonstrates effectiveness against many types of cancers. 


One of the carotenoids needed for strong immune health, lutein also has anticancer properties.


Plentiful research, including a study in the journal Anticancer Agents in Medicinal Chemistry, shows that lycopene helps protect against prostate cancer.


An essential mineral, research shows that, providing you don’t exceed recommended dosages, selenium can help with cancer prevention. 

Vitamin A 

Research in the journal Science Reports found that vitamin A, beta carotene, and lycopene in the diet might assist in fighting pancreatic cancer. 

Vitamin C

A critical nutrient for great immune health, vitamin C also helps fight free-radical damage linked to cancer.

Vitamin D 

Not only is vitamin D connected to preventing many types of cancer, but a study published in the Journal of Clinical Oncology suggested that vitamin D may help prolong lifespan in people suffering from cancer.

Vitamin E 

Vitamin E is an antioxidant that helps protect your body from toxins in the environment and your food.
