046 - Concussions and the Canadian Food Guide

Chris gets surprisingly aggressive (and hairy) during a football match, which leads the boys to discuss concussions. Jacob goes to a hockey game and finds a lot of people who are intimately familiar with mild traumatic brain injuries. How common are they, what’s the treatment for them, and should you let someone with a concussion fall asleep? Perhaps more importantly, would you let your kid play football (or hockey)? Also: a new iteration of the Canadian Food Guide gets rid of food groups; talcum powder strikes back; probiotics make surprising appearances in our food supply if we are to believe Canadians; and a joke few people will get. It’s Skeptics with a—wait, wrong show.   Vox pop by Jacob Meza of the So It Is Told podcast.   Jingle by Joseph Hackl.   Additional music by Seth Donnelly and Kevin MacLeod.   Theme music: \"Troll of the Mountain Swing\" by the Underscore Orkestra.   To contribute to The Body of Evidence, go to our Patreon page at: http://www.patreon.com/thebodyofevidence/.   Patrons get a bonus show on Patreon called “Digressions”!
