7-eleven just turned 88. To celebrate they gave away free slurpees all day today. While that may have been intended as a nice gesture to thank their loyal customers, were they really doing their customers a favor? Slurpees contain up to 33 grams of sugar each. That is almost 1.5 times the daily recommended sugar allowance for an average woman and a full day’s allowance for a man, according to the American Heart Association. It got me thinking – what will those 7-eleven slurpees do to your brain? This excellent Ted talk from Nicole Avena provides the answer to that question.
