Nutrition Hacks for Improved Focus, Memory, and Mental Clarity [Ep. 17]

podcast Feb 26, 2020

A big part of maximizing your score on test day is how well you're able to focus and concentrate throughout the entire exam.

You've spent months learning all of the how-to's for answering questions correctly, but if you have "brain fog" and aren't able to think clearly and remember everything you've studied when it comes time to actually sit down and take your test, it's all for nothing. 

Optimal nutrition can play a huge role in maximizing your brain's performance so that you can maintain mental clarity for your best possible result. To discuss this important topic, we're joined in this episode by Dr. Barrett Deubert, a chiropractor and nutrition expert in Knoxville, TN, who shares practical and actionable nutrition hacks that you can employ throughout the entire process of preparing for and taking your standardized test.

Listen to our conversation here:


Specifically, we discuss:

  • How the brain works and the types of macronutrients you should be fueling it with on a daily basis;
  • High-powered brain foods that fuel maximum concentration;
  • 5 foods to stay away from to avoid "brain fog" and other lapses of mental clarity and focus;
