Elderberry, Echinacea, Cranberries: Miracle Cures or Just Hype for Your Cold and Flu?
Any other berries that might be helpful? A randomized, placebo-controlled, interventional study—funded, predictably, by Ocean Spray—found that the gamma-delta-T-cells of those drinking a low-calorie cranberry juice beverage for ten weeks appeared to be proliferating at nearly fivefold the rate. These immune cells “serve as a first line of defense.” Though the study participants didn’t get fewer colds, they did seem to suffer less, but not enough to prevent days missed from work or an impairment of their activities, as shown here and at 3:56 in my video.
