  • In addition to suppressing liver cancer growth in vitro, cranberries have often been found to have similar effects against human breast, colon, brain tumor, oral, and ovarian cancer cells.


  • Here's the latest looking at prostate cancer cell growth.


  • The United States has the highest rate of prostate cancer in the world, so let's try a native American fruit.


  • Researchers started out with about 50,000 human prostate cancer cells in a petri dish, and if you do nothing, within a day you're closer to 100,000, then 200,000, then nearly 400,000 within 72 hours.


  • But by adding just a smidgen of cranberries, or two smidgens, you can see they block that exponential cancer growth.


  • The reason they tested such tiny concentrations, is that we only absorb a small fraction of the cranberry phytonutrients we eat into our bloodstream.


  • Still, cranberries are cheap.


  • If drug companies and supplement manufacturers are going to capitalize on this, they needed to find cranberry's active ingredient.


  • Here's some of the various phytonutrients in cranberries.


  • So different fractions were tested against various types of cancer to find the magic bullet.


  • Yes, the anthocyanin phytonutrients inhibit colon cancer cell proliferation about 15% for example, about the same with the proanthocyanidins fraction, but nothing compared to the total cranberry extract of the whole fruit.


  • There seemed to be an additive or synergistic antiproliferative effects, resulting from a combination of the various components compared to individual purified phytochemicals".


  • So it's always better to eat the whole fruit.


  • How do you do that with cranberries, though?


  • Although 5% of cranberries are sold fresh, the vast majority are consumed as processed products.


  • To get the same amount of anthocyanin phytonutrients in a cup of fresh or frozen cranberries, you'd have to drink 16 cups of cranberry juice cocktail, eat 7 cups of dried cranberries, or 26 cans of cranberry sauce.


  • The problem is that raw cranberries are so tart that folks may opt for the dried.


  • In a taste test survey, consumers said they wouldn't mind eating sweetened cranberries every day, whereas raw cranberries sloped down towards maybe once a year.


  • The problem is dried cranberries tend to come sweetened.


  • Raw cranberries don't affect your blood sugar, but sweetened dried cranberries do, even the low-sugar varieties.


  • What about cranberry juice, or shall I say quote, unquote juice?


  • Cranberry cocktail is only about a quarter cranberry juice.


  • The ruby red phytonutrients in cranberries and pure cranberry juice are powerful antioxidants, increasing the antioxidant capacity of our bloodstream within hours of consumption.


  • But the high fructose corn syrup acts as a pro-oxidant, even if you add vitamin C to it as they did here, canceling out some of the cranberry benefit.


  • So how do you get the upsides without the down?


  • Check out my pink juice video, where I offer a recipe for making no-sugar-added whole fruit cranberry cocktail.
