The 10 Most Functional Foods In The World Which Destroy Cancer Cells

5_foods_tnf2Many specific proteins, enzymes and coding within our immune system may be activated to kill cancer cells. There is no such thing as a cancer cell that cannot be defeated by the human immune system. The difference between cancers that grow and those that don’t are what we put in our bodies to prohibit their growth. Proteins can be rendered ineffective if cells experience uncontrolled growth though damage or mutations to DNA or if toxins through food and chemical pollution override the immune system’s natural function. Here are 10 functional foods which suppresses tumour development during immune surveillance in the human body.

Scientists have found that healthy cells damaged by chemotherapy secreted more of a protein which boosts cancer cell survival. Chemotherapy has been proven to cause cancer cells to interact with nearby tumour cells and cause them to grow, invade, and importantly, resist subsequent therapy. Where conventional medical treatment fails cancer patients, natural foods succeed.

In a study published in the journal Science Translational Medicine, scientists identified a molecule, known as TIC10, which activates a protein that helps fight the disease. The protein, called TRAIL (tumour-necrosis-factor-related apoptosis-inducing ligand) suppresses tumour development it can actually cross the blood-brain barrier, which separates the main circulatory system from the brain.

Through the body’s infinite wisdom, its systems recognize foreign invaders and poisons such as chemotherapy which are not beneficial for the brain. Many cancer drugs are consequently blocked from passing the blood-brain barrier. However, TRAIL is permitted passage due to its beneficial effects on the immune system.

Another positive is that TIC10 does not just activate the TRAIL gene in cancerous cells, but also in healthy ones. This is known as the ‘bystander effect’ – i.e. where cells near cancerous cells are also killed.

Nearby healthy cells are also given a boost to increase the number of cancer-killing TRAIL receptors on their cell surface.


 1. Turmeric

Curcumin, possibly the most powerful antioxidant known from the popular Indian spice Turmeric, has countless health benefits. A recent study led by a research team in Munich showed that it can also inhibit formation of metastases.

Curcumin exerts anti-inflammatory and anti-oxidative effects by inhibiting tumor necrosis factor-alpha (TNF-alpha), suggesting that its effect on endothelial function may be mediated by the suppression of inflammation and/or oxidative stress via down-regulation of TNF-alpha.

One of the most comprehensive summaries of a review of 700 turmeric studies to date was published by the respected ethnobotanist James A. Duke, Phd. He showed that turmeric appears to outperform many pharmaceuticals in its effects against several chronic, debilitating diseases, and does so with virtually no adverse side effects.

2. Sea Vegetables

 Nori, hijiki, wakame, arame, kombu and kelp are just a few of several varieties of sea vegetables with potent effects on cancer. They are a rich source of many wonderful minerals, including magnesium, calcium, iron, and bioavailable iodine.

But since chronic, unwanted inflammation and chronic oxidative stress are both risk factors for development of cancer, it would be quite natural for scientists to be interested in sea vegetables are anti-cancer foods not only in the case of colon cancer, but for other types of cancer as well. Sea vegetables are well-researched as containing a variety of anti-inflammatory and antioxidant compounds, and this nutrient combination delivers some risk-lowering benefits in the case of colon cancer and other cancer types.

Of special note in this area of cancer and sea vegetables is the issue of estrogen-related cancers, especially breast cancer. Intake of sea vegetables appears able to modify various aspects of a woman’s normal menstrual cycle in such a way that over long periods of time (tens of years) the total cumulative estrogen secretion that occurs during the follicular phase of the cycle gets reduced.

3. Grapes and Resveratrol

Resveratrol is a phenolic compound that contributes to the antioxidant potential of red grapes.

Resveratrol is not only an antioxidant and antimutagen, but also reduces oxidant-caused cell death. Resveratrol has been shown to inhibit production of nitric oxide and tumor necrosis factor alpha (TNF-A) by lipopolysaccharide-stimulated Kuppfer cells. Kuppfer cells are macrophages fixed in place in the liver. Their chronic overproduction of nitric oxide and TNF-A due to chronic infection can cause severe liver damage.

Perhaps Resveratrol’s most important property is its ability to inhibit cyclooxygenase-2 (CoX-2). CoX-2 is related to cancers and abnormal growths in the intestinal tract. Natural CoX-2 inhibitors such as resveratrol have been shown to reduce the occurrence of cancers and pre-cancerous growths. So while pharmaceutical companies race to find complex agents that inhibit CoX-2, the ingredient is already present in red grapes which if consumed daily (or via organic grape juice) will protect against tumors naturally.

4. Chlorella and Spirulina

Scientists in South Korea recently found that carotenoids from chlorella may be effectively used to prevent cancer in humans. They discovered the primary carotenoid from C. ellipsoidea is violaxanthin, while the major carotenoid from C. vulgaris is lutein. They examined the activity of semi-purified extracts of these carotenoids against human cancer and found they inhibited cancer cell growth in a dose-dependent manner.

Chlorophyll neutralizes environmental toxins and pollutants. It helps the blood carry oxygen to all cells and tissues. Cancer cannot thrive in cells that are fully oxygenated. Chlorophyll plays a part in chlorella’s ability to detoxify heavy metals, and is a natural wound healer. There is evidence that chlorophyll reduces the ability of carcinogens to bind with DNA in major organs. Its anti-mutagenic properties make it protective against toxins such as pharmaceutical drugs.

Spirulina simply is unable to remove heavy metals like chlorella does, as it lacks a cell membrane, however it shows significant immune-boosting properties. It is is made of a spiral strand which gives it its name. Spirulina is rich in vitamins B, E, K and beta carotene as well as iron and magnesium and essential fatty acids. It contains amino acids that promote improved mental functioning, vitality and energy, and balanced blood sugar. According to a study done in China, selenium-infused spirulina inhibited the growth of breast cancer cells.

5. Green Tea

The health benefits of green tea are due to the presence of a group of plant flavonoids called catechins. Of particular interest to researchers is epigallocatechin-3-O-gallate (EGCG), the primary catechin in green tea. For example, South Korean researchers have found that EGCG blocks TNF naturally by interfering with the ability of certain pro-inflammatory chemicals to bind to cells of smooth muscle tissue of the vascular system. In a 2009 study conducted by the Chonbuk National University Medical School, it was noted that the specific mechanism of action of EGCG in terms of blocking TNF is the suppression of fractalkine, an inflammatory agent specifically involved in the development of arteriosclerosis, or hardening of the arteries.
