Probiotics cut cold symptoms
by Newsletter Editor
Doctors said earlier studies found probiotics reduce the number, severity, and length of colds in the old, young, the healthy sedentary, and in highly trained athletes, but that no research exists on health-conscious, physically active men and women.
This study involved 465 healthy adults who regularly engaged in a range of physical activities from daily walking to competitive amateur athletics. Participants took a daily dose of Bifidobacterium lactis, with or without Lactobacillus acidophilus, while a third group took a placebo. After 150 days from the fall through the spring, compared to placebo, those who took Bifidobacterium lactis were 27 percent less likely to have developed an upper respiratory tract infection. Also, the placebo group caught colds sooner, with the probiotics group healthy about three weeks longer.
The group that took the combination of Bifidobacterium lactis with Lactobacillus acidophilus was able to be significantly more physically active than the placebo group.
