What five foods not to eat before running?

Heavy foods: Best not to eat heavy foods including greasy/fatty high protein (especially if large serving size) large portions usually acidic foods bother people (oj, tomato juice, citrus fruit) physically hard foods (such as nuts).

Light food if at all: There are many foods that really should not be eaten right before running- anything heavy (meats, etc.) It can be an individual thing though. I drink a small amount of a pre-workout beverage, and maybe eat a couple crackers with some honey on them. Go light.
