KNOXVILLE, Tenn. (WVLT) -- Our digestive system is key.
Dr. Pete Sulack told Local 8 News it keeps our immune system up and it helps us deal with stress. That takes a good probiotic.
"The stronger I can make the digestive system, the stronger I can make your overall health," said Dr. Pete Sulack, America's Leading Stress Expert and founder of Unhealthy Anonymous.
So he said we need to add something like kefir to our diet. Some like to call it a drinkable yogurt, but it has even more probiotics than yogurt.
"In a world where there's a ton of antibiotics, antibacterial soap, and hand santizers, we think all bacteria is bad," said Dr. Pete. "Kefir and probitoics are different."
You can usually find it in the dairy section. Dr. Pete said it comes from a Turkish word called keif, which means to "feel good." That's what it's all about -- making your digestive system healthy, so you can feel good.
"Kefir's beneficial for allergies and sinus problems. It's great for irritable bowel syndrome and removing inflammation from the gut," said Dr. Pete. "In fact it's been proven to kill cancer cells in many studies."
If you're having problems with spring allergies, Dr. Pete said it can help with that. He said the good bacteria destroys the bad bacteria.
"Probiotics are great because they grab those mutagens and harmful bacteria and help eliminate it from the body," said Dr. Pete.
For those of you who are lactose intolerant, Dr. Pete said it's not a worry.
"The fermentation process literally helps the body absorb and digest the lactose in advance of you consuming it," said Dr. Pete.
When you're picking up a bottle of kefir, Dr. Pete prefers an organic one. He said there's no antibiotics or hormones and it's a great source of healthy fat.
