Study: 80% of the Protein in Sweet Potatoes Kills Several Types of Cancer Cells
Sweet potatoes can be considered a superfood. They are one of the healthiest and cheapest vegetables on the planet. (And one day, perhaps, even off the planet, as NASA has chosen the sweet potato for space missions.) A study out of the University of Washington aimed to identify which vegetables provided the most nutrients per dollar. In my video, Anti-Cancer Potential of Sweet Potato Proteins, you can see a graph of affordability versus nutrition for different foods. The healthiest foods, like dark green leafy vegetables, may also be the cheapest, and the highest nutrient-rich food scores per dollar were obtained for sweet potatoes.
Sweet potatoes are not just packed with nutrition but may also have special cancer-fighting properties. In 1931, a unique protein was discovered in sweet potatoes. It turns out that 80% of the protein in sweet potatoes is a type of protease inhibitor with potential anticancer effects. These proteins were originally tested against leukemia and appeared to suppress the growth of leukemia cells in a petri dish.
You are probably wondering how a sweet potato protein can enter into the bloodstream.
The moment you intake proteins in your stomach, they start to digest. Scientist tested sweet potato proteins against cancer cells on tongue, since they touch our mouth, in order to get around the problem of digestion.
It is necessary to find alternative therapies for those with tonque cancer, because they are treated with chemotherapy which has harmful effects.
According to the scientists, sweet potato can be beneficial for tongue cancer in humans since its protein diminished the in vitro cancer viability in just couple of days.
But can sweet potatoes aid in the treatments of other cancer types too?
Researchers conducted a study on 9 women with advanced cervical cancer, using this unique class of proteins, where 2 of which showed that this protein class survives the digestion process and can be absorbed in the bloodstream intact.
Recently, the protein of sweet potatoes was tested on one of the most common and deadly type of cancer, the colorectal cancer.
The scientists have been looking for anti-metastatic agents because in the early stages micrometastases appear outside the colon and can result to recurred cancer and death.
This amazing protein from sweet potatoes not only slows down the development of colon cancer cells, but it also reduses the cancer cell invasion and migration.
Sweet potatoes are linked to reduced rate of gallbladder cancer, although this was never tested.
Sweet potatoes beside being very beneficial to our health, they are also very delicious. During winter, you can heat them and put them in your pockets to act as your natural hand warmers, and then you can use them as an instant healthy snack.
