Pro-what?? Probiotics!

Probiotics are foods that nourish the harmless bacteria that live in your gut. 

Just as antibiotics kill bacteria, probiotics enhance their growth.


Bacteria and other microbes might be very influential regarding good health.

The human body contains 10 times more microbial cells than human cells.

About 2 to 6 pounds of these microbes live in the intestines, where they help

digest food, synthesize vitamins, and enhance the immune system. This gut

ecosystem changes according to diet, use of antibiotics, heatstroke, and other

factors (some known, some unknown). For example, the gut bacteria of obese

children can differ from that of lean kids, just as the gut bacteria of gastric

bypass clients can change after surgery. (Maybe this is one reason why bypass

patients lose weight faster than predicted?)


Microbes might play also play a role in Alzheimer's disease, hyperactivity in

kids, and heart disease, so take good care of your gut! This means enjoying

fiber-rich fruits, vegetables, and whole grains (microbes like to eat fiber) as

well as cultured foods (yogurt, kefir) and fermented foods (miso, Kimchi, tempeh,

blue cheese). Probiotic supplements might also be helpful.


For female athletes with PMS, taking probiotics for the seven days before the

start of the menstrual period might reduce PMS symptoms, as well as the risk

of diarrhea (a common problem at the time of the menstrual period). Give it a try?
