An Analytical Study on CARB Rich Foods (Tubers), Its Glycemic Index And Effect On Glucose Spike On Diabetic Individuals

Diabetes mellitus is a growing epidemic in India, with Puducherry reporting a notably high prevalence (16.5%). This study focuses on the glycemic impact of commonly consumed tuber-based carbohydrate-rich foods—specifically carrots (low-GI) and tapioca (high-GI)—on diabetic individuals. A sample of 100 participants from Puducherry was initially surveyed, with 40 selected for detailed glucose monitoring (15 normal, 9 pre-diabetic, 16 diabetic). Fasting and postprandial (90-minute) blood glucose levels were measured after consumption of these tubers.Results demonstrated a 3.8-fold greater glucose spike with tapioca (+65 mg/dL) compared to carrots (+17 mg/dL), with tapioca exceeding the ADA danger threshold (>140 mg/dL). The high fiber content in carrots (3.6g/100g vs. tapioca’s 1.4g/100g) contributed to slower glucose absorption. Despite cultural perceptions that both tubers are "safe," this study disproves such myths, emphasizing that low-GI carrots are diabetic-friendly, while high-GI tapioca poses significant risks. The findings highlight the need for targeted nutritional education to correct misconceptions and improve diabetes management in high-risk populations.
