Last week, I showed you the incredible ability of resveratrol to fight the aging process. And in the past, I've showed you how powerful resveratrol is at fighting cancer. But what if I told you there's a nutrient that's even more powerful than resveratrol for fighting digestive cancers, including colon cancer?
As you may know, resveratrol has a cousin - pterostilbene. Resveratrol comes from grapes and pterostilbene comes from blueberries (though you'll also find it in grapes, cranberries, and other small berries). They serve very similar roles in their respective fruits – that is fighting off pathogens like bacteria and fungi that attack the fruit. This is why they're so effective at fighting off disease in humans. But new evidence suggests pterostilbene is even more powerful than resveratrol at fighting off digestive cancers.
The evidence comes from a study out of National Kaohsiung Marine University in Taiwan and published in the Journal of Agricultural and Food Chemistry. In this study, the researchers found that pterostilbene was more effective at increasing the expression of certain genes that are responsible for the generation of powerful protective antioxidant enzymes. But it did more than just provide antioxidant protection.
The pterostilbene also helped decrease inflammation in the colon, which is a major contributor to colon cancer. The researchers were so impressed with its ability to fight colon cancer that they said their "findings strongly suggested the chemopreventive potential of dietary administration of pterostilbene against colonic tumorigenesis."
The researchers said that both resveratrol and pterostilbene block cellular inflammation and fight oxidative stress. However, they said, "pterostilbene was a more potent chemopreventive agent than resveratrol for the prevention of colon cancer." They found that the pterostilbene specifically inhibited the "initiation and proliferation" of colon cancer cells. And it did so in a dose-dependent manner. So the more you take, the better.
At this point, we don't know what the upper dose limits of pterostilbene and resveratrol are, as they are extremely safe nutrients. But most nutrition experts suggest 25-50 mg of each nutrient daily. I don't think that's nearly enough. Most studies show that 250 mg of pterostilbene are perfectly safe. Rat studies show that many times this amount are safe (up to 3,000 mg/kg). So if you want to prevent cancer, I suggest you take at least 250 mg daily. If you're fighting cancer, you'll want to talk to your doctor about how much to take.

This overlooked hormone might be the real reason you still struggle with out-of-control blood sugar. But most doctors (even alternative doctors) ignore it completely.

You also need to include grapes, blueberries, and other berries in your diet every day. A great source of blueberry and other berries is Advanced Greens Formula. This powder is probably the best-tasting nutritional powder I've ever had. It's great in smoothies, in a glass of juice, or any other beverage you want.
