For people with diabetes, carb counting is an important way to make sure your blood glucose levels stay in your target range. Fehling’s reagent also has the same. A healthy range is 6. The Benedict's test identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional groups. It is a diet intended mainly for Crohn's disease, ulcerative colitis, celiac disease, diverticulitis, cystic fibrosis and chronic diarrhea. Benedict's test • Reducing sugars give positive Benedict's test due to their free aldehyde or keto group. Complex carbohydrates such as starches DO NOT react positive with the Benedict’s test unless they are broken down through heating or digestion (try chewing crackers and then doing the test). The media in each tube contains a single carbohydrate – in this case glucose, lactose, and sucrose. William Shaker, John S. Sugar is “sticky”, it sticks to hemoglobin (glycation), and correlates very well to various diabetic related diseases. Procedure of Barfoed’s test: Take 1ml of test sample in dry test tube. Formation of a purple ring at the interface indicates positive result. This study aimed to investigate the satiety effects of isocalorically replacing carbohydrate energy in a meal with avocado-derived fats and fibers.
