Foods that fight and prevent cancer

By Dr. Justin Marchegiani

Rates of cancer in our country have been trending upward at an alarming rate. In the 1900s, one in 20 developed cancer, nowadays, it’s one in three! The cancer industry spends most of its time creating new guidelines for treating cancer, rather than preventing it. And when we look at how much money is brought in through chemotherapy drugs, radiotherapy, surgeries, and all other aspects of typical cancer diagnostics and treatments, it’s clear that we have to take prevention into our own hands.

Everyone creates cancerous cells in their bodies, however, in healthy bodies with strong immune systems, they mutated cells are quickly disposed of. There are many health aspects to consider in cancer prevention, in this article we are going to focus on the top cancer-fighting foods.

Green Leafy Vegetables

Kale, collard greens, arugula, and spinach are all rich in vitamin C, antioxidants, and beta-carotene. They are antiviral and antifungal, and the chlorophyll that gives these veggies their green color purifies the blood, eliminates toxins, and rebuilds new blood cells.


Many conventional oils actually destroy cell membranes and lead to diseased cells. Opt instead for olive oil, coconut oil, or even grass-fed butter! The phenols present in these oils will boost your immune system and contain anti-aging and anti-carcinogenic properties.


Powerful mushrooms have been used for centuries to fight cancer and boost the immune system. Reishi, Cordyceps, and maitake are some of the most powerful mushrooms for a wide range of health benefits. They can be consumed whole or taken in capsule and tincture form.


Over 80% of your immune system is housed in your gut, so a healthy microbiome is crucial for a healthy you. Eating probiotics, even taking them in capsule form, has been suggested to have the ability to stop tumor growth! Probiotics can be found in foods such as sauerkraut, kimchi, kombucha, and raw milk kefir and yogurt.

Cruciferous Veggies

More green vegetables that are rich in vitamin C include brussels sprouts, cauliflower, and broccoli. Glutathione, known as the master antioxidant, is present in these veggies, along with other powerful antioxidants called sulforaphane and indoles, which are responsible for the stimulation of detox enzymes which protect the structure of DNA.

Nuts and Seeds
