The 2015 documentary That Sugar Film sounds like a treat, until you realize that it’s not all Candyland when it comes to refined sugar. Like the documentary Super Size Me, where Morgan Spurlock stuffed his face with high-fat foods from McDonald’s, That Sugar Film follows Australian actor Damon Gameau as he delves deep into the world of sugar in our food supply, and reveals that even the healthiest-looking snacks are loaded with the unhealthy sweetener. That Sugar Film screens with a panel discussion of health experts on Friday, Aug. 4, at Songbird Community Center, 8297 Old Redwood Hwy., Cotati. 7pm. $10 donation. 707.795.2398.
