- Gastroesophageal reflux disease (GERD)
- Gastroesophageal reflux disease (GERD) is a disease in which acid from the stomach leaks back into the esophagus, usually because of a problem with the lower esophageal sphincter. Persistent heartburn is the most common symptom.
- Glycemic index (GI)
- Glycemic index (GI) is a method for ranking foods according to their effect on blood sugar, or glucose. Foods that have a low glycemic index produce small fluctuations in blood glucose, and leave you feeling fuller, longer. Foods with a high glycemic index produce a quick rise in blood glucose, and are usually also higher in calories.
