Should I stay away from eating energy bars during or before a match? I had a lesson earlier this week that I was running late for, I hadn't eaten lunch so I grabbed a power bar to hold me over. I don't plan on making a habit of it. My brother says it can upset your stomach during play... I was wondering if energy bars are a good idea or not... If I'm hungry before a match and need something on the go what should I eat? (I'll normally have different mixxes of nuts/ nuts and dried fruit, but sometimes I don't have any mixxes ready) If anyone out there does support energy bar usage, which would you recommend?
