Raspberries and Cancer

Red Raspberries

Promote Wound Healing, Reduce Heart Disease, and More!

When indulging in a summer snack of red raspberries, it may be comforting to know that our Paleolithic ancestors were eating the same food. As one of the oldest fruits, it may not be surprising to learn that there are 200 different varieties of raspberries. More than just a tasty summer fruit, nearly every part of the raspberry plant has a medicinal use.

Raspberries are associated with fertility in Greek mythology. Greeks and Chinese used red raspberry to treat diarrhea and dysentery, and to aid in healing wounds. The people of Tibet use red raspberry leaves to cure emotional problems, infections, and exhaustion. Many Native American tribes have also used raspberry. The Cherokee tribe used red raspberry root to treat toothaches and coughs. The Chippewa used it to treat measles, and washed their eyes with a tea made from raspberry root bark to heal cataracts. The Iroquois tribe used various parts of the plant to treat kidneys and blood pressure, among other things.

And if that’s not enough to ask from one little berry, research has shown that one of the major benefits of red raspberries is their ability to fight cancer. This is because of the ellagitannins present in the fruit. Research done by Dr. Daniel Nixon at the Hollings Cancer Institute has shown a number of surprising results. Here are just a few of them:

  • Consuming one cup of red raspberries per day (40 mg of ellagitannins) prevents the development of cancer cells.
  • Red raspberry ellagitannins protect human cells against cancer-causing agents in tobacco smoke, food additives, and petroleum-based substances. Ellagitannins act as scavengers to "bind" cancer-causing chemicals, making them inactive.
  • Red raspberry ellagitannins also protect DNA by blocking carcinogens from binding to the DNA.
  • Red raspberry ellagitannins slow the growth of abnormal colon, breast, skin, prostate, pancreas, and leukemia cells in humans.
  • Red raspberry ellagitannins lower the incidence of birth defects, promote wound healing, reduce heart disease, and may reduce or reverse chemically induced liver fibrosis.

Which brings us to the question of how to obtain the benefits of eating red raspberries. Dr. Nixon used one cup of red raspberry puree per day in his studies on raspberries and cancer. However, that is not practical for most people. Fortunately, it turns out the raspberry seeds have a much higher concentration of ellagitannins than the puree. By raspberry variety, they are:

  Seeds Pulp Whole
Meeker 8.40 3.36 4.31
Chilliwack 7.78 2.58 3.39
Willamette 8.13 2.05 2.91
Average 8.10 2.66 3.54

Ultimate Antioxidants from Baseline Nutritionals

As you can see in the above table from the Washington State Red Raspberry Commission, over 70% of the ellagitannins present in the Meeker red raspberry are found in the seeds. In fact, one gram of red raspberry seed powder, taken twice a day, provides 40 mg of ellagitannins -- equivalent to the amount of ellagitannins found in one cup of fresh red raspberries.

In addition to the above benefits, raspberries also have antioxidant properties. A study on organic VS non-organic raspberries showed organic raspberries to be significantly higher in total antioxidant capacity than non-organic raspberries. And, the riper they are the better, since berries in a recent study that were fully ripened showed the greatest overall antioxidant benefits.

    Referring to :

    "Consuming one cup of red raspberries per day (40 mg of ellagitannins) prevents the development of cancer cells. At low concentrations, it slows the growth of cancer cells; at higher concentrations, it tells cancer cells to kill themselves."

    What is the definition of low, and higher concentrations in mg per day ??

    Thanking you in advance,
