Probiotics Change Brain Activity, Emotional Response

Researchers from UCLA's Geffen School of Medicine have determined that consuming a milk fermented with probiotics changes the brain activity of women.

The UCLA medical researchers divided 36 healthy women into three groups. One group was given a milk fermented with probiotics twice a day. Another group was given a milk without the probiotics. The other group was given no milk product.

Before the study began the women underwent extensive brain MRI studies and brain activity tasking response analyses. Then the women consumed the probiotic or placebo milk for four weeks, followed by repeated testing.

Along with the MRI testing, the researchers tested brain responses to emotional faces, as well as during rest. They utilized analyses that tests emotional response.

After the four weeks, those women who drank the probiotic milk had significantly different brain activity changes. Their task-related responses increased, and their activity within the sensory cortex regions changed, which was dramatically illustrated during rest periods. Their midbrain connectivity increased, which the researchers concluded probably explained their task-related response increases.

Their altered brain activity also illustrated changes in the brain signaling pathways for emotional responses among the women.

The probiotics in the fermented milk included Bifidobacterium animalis, Streptococcus thermophiles, Lactobacillus bulgaricus, and Lactococcus lactis. Each of these species has been shown in other clinical studies to improve health among other organs and tissue regions of the body.

Research has also connected the gut's probiotics to the brain via a conduit between the central nervous system and the enteric nervous system. The enteric nervous system is located in the abdominal region around the digestive tract. Many of our neurotransmitters are produced in this region and the neurons relay mind-body responses between the gut and the brain stem.

The researchers concluded: "Four weeks intake of a fermented milk with probiotics by healthy women affected activity of brain regions that control central processing of emotion and sensation."

The research was led by Dr. Emeran Mayer, a UCLA professor of medicine and a specialist in gastroenterology. He is the Director of the Oppenheimer Center for Neurobiology of Stress. Dr. Mayer is well-known for his research in identifying the gut and its probiotic content as "the second brain."

Sounds like Kefir to me!

I have been using Kefir for just over a year. It is really helpful for all over improvements. It is far superior to yogurt.

This is the one I use, but there are others.
I get mine now at Costco. But local Kroger's has it too.
It seems to be moving into regular stores more commonly.

Theirs is very very tasty too.

Just bought some kefir (same brand) yesterday and loved it! I've eaten yogurt for years, now I'll be incorparating kefir into my diet. I wonder if other fermented foods have the same neuro impact?

I have heard that organic fermented sauerkraut is good too.

But my GI tract cannot handle cabbage in any form, so I can't
comment on it personally.

The Lifeway Kefir has 12 strains of probiotics in them. After about 6mos of daily, I cut back to 2 or 3 times a week. It seems to rejuvenate me, and I have chronic GI issues and it fixed those quite well.

It is in our home now for good!

I am happy for you that you like the Kefir too! It's a win-win type food!

P.S. ...for females there are other benefits...in the female department.
After a month or so you may notice that too.
