Postprandial Glycemia

Overweight and obesity affect nearly 2.5 billion adults worldwide and increase cardiometabolic risk. Postprandial glucose excursions are influenced by diet and inactivity and predict metabolic disorders, while South Asians, particularly Pakistanis, are more vulnerable due to genetic and lifestyle factors and processed diets. This study evaluates the impact of chia seed (Salvia hispanica L.) ingestion on postprandial glycemia and appetite in overweight adults, supporting UN Sustainable Development Goal 3 (Good Health and Well-being). A randomized controlled crossover trial will be conducted among 30 overweight adults (BMI 25-29.9 kg/m²), aged 18-40 years. Participants will undergo control and intervention phases separated by a 14-day washout. The control beverage will contain 50 g glucose in 250 mL water, while the intervention beverage will contain the same beverage supplemented with 30 g chia seeds. Glucose response will be assessed using incremental area under the curve (iAUC) by the trapezoidal method, with appetite response also evaluated. Data will be analyzed using SPSS version 25; baseline characteristics will be presented as mean ± SD, and between-group differences will be assessed using a linear mixed model at p \< 0.05. Chia seed ingestion is expected to reduce postprandial blood glucose and improve appetite control.

This clinical study aims to examine how acidic drinks (lemon juice and apple cider vinegar) affect blood sugar when consumed with a starchy food. The study focuses on healthy individuals and aims to understand whether these drinks can slow the rise in blood sugar after meals and affect feelings of fullness. The main questions this study aims to answer are: Do lemon juice or apple cider vinegar lower the rise in blood sugar after a meal? Do these drinks increase feelings of fullness? Do different amounts change their effects? Researchers will compare lemon juice and apple cider vinegar to see which one is more effective. Participants will: Consume white bread in the morning on an empty stomach with one of the following drinks: Water only Water with lemon juice (50 g or 100 g) Water with apple cider vinegar (10 g or 20 g) Have a one-week break between each test. Have their blood sugar measured at regular intervals for 3 hours after eating. Report their level of fullness using a simple scale. This study explores whether simple and practical dietary choices can help manage blood sugar levels. The findings may support new, easy-to-apply nutrition strategies for managing diabetes and weight.
