Yogurt to Reduce Stress

When preparing for the SAT, ACT, or any other exam, considering the effect of nutrition on academic performance is critical.
Here at Granite Prep we are fascinated by what makes students into great test takers. When preparing for the SAT, ACT, or any other exam, considering the effect of nutrition on academic performance is critical. The connection between nutrition and academic performance is not a new one; however, thanks to cutting edge research the importance of brain food for students is more clear than ever before! Probiotics have recently become the focus of countless innovative research studies, as more scientists are asking: how does nutrition affect learning?
Probiotics and Anxiety:
A team of neuroscientists led by John F. Cryan at The College University of Cork in Ireland made breakthrough discoveries on the impacts of probiotics and mood. Cryan compared the performance of mice who received a diet rich in Lactobacillus to a group of mice who did not receive any probiotics. The mice were placed in mazes and their behavior and stress hormones were monitored. The mice who had a diet rich in probiotics were notably more curious, less anxious, and showed lower levels of the stress hormone corticosterone. Furthermore, the mice had a healthier distribution of the neurotransmitter “GABA” (the same neurotransmitter targeted by most fast-acting anti-anxiety medication). In Cryan’s own words: “These mice were more chilled out.“
The mice who had a diet rich in probiotics were notably more curious, less anxious, and showed lower levels of the stress hormone corticosterone.
As was discussed in “Getting Over Test Taking Anxiety“, a calm mind is a higher achieving mind. Therefore, the anxiety reducing properties of a probiotic rich diet could be extremely beneficial for students struggling with test taking anxiety.
Probiotics and Endurance:
“The mice with a probiotic rich diet simply wouldn’t give up.”
Upset Stomach and Exams:
One day before the students’ big exam, the “probiotic group” had notably less stress hormones (cortisol) in their system than the “no-probiotic group”.
Dustin tells us that some of his favorite ways to enjoy his farm’s amazing probiotic rich creation include: “with honey and granola for breakfast” or “in a smoothie”.
