Nowadays many people suffer from cancers and they find cancer stem cell killing foods so much more.
They try to find a way that able to kill cancer stem cells has been one of the holy grails in cancer research.
Actually this is a main target of biotechnology companies working on cancer treatment and scientists have already discovered cancer stem cell killing foods which known as dietary factor that have the ability to kill cancer stem cells, at least in some forms of cancer.
Cancer stem cells are responsible for initiating many cancers, as well as igniting the recurrence of cancers after treatment.
This article will be so much important for those who find cancer stem cell killing foods. Here are the top cancer stem cell killing foods.
Best cancer stem cell killing foods
1. Green Tea & Matcha Tea
Everybody knows that Green tea has many powerful functions. Most important thing is it has the ability to kill cancer stem cells.
Scientists at Nanjing Medical University and Sun Yat-Sen University Cancer Center in China able to show the effect of the green tea polyphenol, epigallocatechin-3-gallate (EGCG), in the lab and found that it could reduce the growth of colon cancer stem cells by 50 percent.
In addition, EGCG forced the cancer stem cells to commit cell suicide through the process of apoptosis.
Not only that but also the University of Salford in England showed that matcha green tea, a form of powderized tea leaf, can interrupt the metabolic pathway of breast cancer stem cells, depriving them of energy and causing them to die.
The effect of the EGCG in green tea on targeting cancer stem cells may help explain the protective effects of tea against colon and other cancers.
2. Purple Potatoes
Originating from Peru, purple potatoes were gifted by the ancient Inca for their nutritive benefits.
They contain the bioactive anthocyanin, a blue-purple pigment that also gives many dark berries their hue.
Scientists at Penn State University explain the effect of purple potatoes on cancers and recognize as cancer stem cell killing foods .
In the lab, they fed mice that are at high risk for developing colon cancer the dietary equivalent of one purple potato (Purple Majesty variety) each day for a week.
The scientists compared the effects of the potato with that of an anti-inflammatory drug called Sulindac, which is known to suppress colon polyps and colon cancer development.
After one week, the colons of the mice were examined. The mice fed purple potatoes had 50 percent fewer tumors.
When the colon tissues were more closely examined under the microscope, there was a 40 percent increase in the killing of colon cancer stem cells compared to the group that did not eat purple potatoes.
They found that the cancer stem cells in mice fed purple potatoes were deprived of key survival factors.
When the scientists removed the cancer stem cells from the mice and exposed them to a purple potato extract, they found the extract caused a twenty-two-fold reduction of aggressiveness in the behaviour of the cancer stem cells.
Not only that they prepared the purple potato in different ways, including baking, dicing, and freeze-drying, yet the bioactive cancer stem cell-fighting components appear to be stable even under different conditions and preparation techniques.
Given their effects, purple potatoes may have in addition to their marvellous colour features unique cancer-fighting properties that traditional white potatoes do not.
This walnuts known as tree nuts that are eaten raw, roasted, candied, or even pickled.
Actually walnuts are nutrient dense and contain bioactive like Gallic acid, chromogenic acid, and ellagic acid.
As I explained earlier, if someone used to eat walnuts is associated with a reduced risk for developing colon cancer and also improves survival in patients who have colon cancer.
Scientists from Ewha Womans University, Seoul National University, and Sungkyunkan University in South Korea studied a walnut extract for its ability to kill cancer cells.It is a best cancer stem cell killing foods.
In the lab, they grew colon cancer stem cells isolated from a patient, and exposed the cells to a walnut extract.
After two days of exposure, the number of cancer stem cells treated with walnut extract declined by 34 percent. By six days, there was a stunning 86 percent suppression of cancer stem cell growth.
The potent effect of walnuts on cancer stem cells might help explain the results of the study of 826 patients with stage 3 colon cancer who had a 57 percent lower chance of death, and a 42 percent lower chance of cancer recurrence associated with eating nuts.
If you have colon cancer, eating walnuts may literally save your life.
4. Extra Virgin Olive Oil
Extra virgin olive oil is one of the best cancer stem cell killing foods which contains a class of bioactive known as secoiridoids, which represent up to 46 percent of the total polyphenols present in olive oil.
These natural chemicals are absorbed in the small intestines and can be detected in the blood plasma and in urine, proving their presence and availability in your body.
Scientists who lived in Spain showed that the lab that olive oil secoiridoids could dramatically reduce the growth of breast cancer stem cells.
When mice were injected with breast cancer stem cells that were exposed to secoiridoids, as many as 20 percent of the mice did not develop tumors.
In the 80 percent that did develop tumors, the tumors were fifteen times smaller and grew at a much slower rate than untreated breast cancer cells. This result is consistent with the suppression of breast cancer stem cells.
It’s so powerful food which is olive oil secoiridoids on stem cells was evidenced at the genetic level: after the breast cancer stem cells were exposed, the bioactives changed the activity of 160 genes involved with controlling stem cells.
One gene was reduced in its activity fourfold, while the activity of another gene that antagonizes cancer stem cells was increased thirteen-fold.
The health-protective power of extra virgin olive oil now extends to targeting dangerous stem cells.
Other cancer stem cell killing foods
There are many bioactive found in foods can suppress cancer stem cells. Genistein is found in soy.
Luteolin occurs in celery, oregano, and thyme. Quercetin is found in capers, apples, and peppers.
All three of these compounds kill prostate cancer stem cells. Luteolin is especially potent and can shut down the activity of prostate cancer stem cells twenty-fold.
The bioactive of green tea, EGCG, has also been shown to work together with the bioactive quercetin to inhibit prostate cancer stem cells as you know.
Some times many bioactives play dual roles and they also able to promote healthy functions in a defense system while combating the opposite effect in the same system.
Chlorogenic acid helps maintain normal circulation through angiogenesis in healthy tissues, while it can simultaneously starve dangerous tumors by cutting off their blood supply.
Similarly, chlorogenic acid enhances normal stem cell function for organ regeneration, but it also cripples cancer stem cells.
In fact, scientists at Nihon University in Japan found that chlorogenic acid blocks the genes supporting lung cancer stem cells, and it increases the activity of genes that kill cancer cells by one-thousand-fold.
How the bioactives work in dual fashion is not well understood.
Foods high in chlorogenic acid include coffee, carrots, and stone fruit, like apricot and plums.
Scientists at Seoul National University in Korea discovered that resveratrol, the bioactive found in red wine, grapes, peanuts, pistachios, dark chocolate, and cranberries, could interfere with the growth of breast cancer stem cells by 60 percent.
Ellagic acid is another bioactive that Has been discovered to target breast cancer stem cell killing foods . Foods high in ellagic acid include chestnuts, blackberries, walnuts, and pomegranates.
