Here's an interesting bit of information about food combinations. According to Bottom Line publications certain foods should not be combined together in meals, for example, don't eat chicken with rice. Why? Because "Some food combinations are easy to digest. They are quickly broken down, and the nutrients are thoroughly assimilated. Other combinations can be a digestive disaster, producing gas, bloating and other gastrointestinal (GI) discomforts."
