Fasting periods apply to all age groups.
1 Examples of clear liquids include water, fruit juice without pulp, carbonated beverages, clear tea and black coffee.
2 Since non-human milk is similar to solids in gastric emptying, the amount ingested must be considered when determining an appropriate fasting time.
3 A light meal typically consists of toast and clear liquids. Meals that include fried or fatty foods or meat may prolong gastric emptying time. Both the amount and type of foods ingested must be considered when determining an appropriate fasting period.
