Pre-meal Load of Raw Almonds & Postprandial Hyperglycemia

Status Completed

Clinical Trial Summary

A few studies show the effect of almonds on postprandial hyperglycemia (PPHG); high blood glucose after meals. In our previous study on intervention with almonds, we observed a significant decrease in HbA1C and a small decrease in fasting blood glucose indicating a possible effect of almonds on PPHG. Studies have shown that a preload of a food article that is high in protein, mono-unsaturated fatty acids, fiber, and low in carbohydrates, such as almonds could be helpful in stimulating insulin secretion and help improve postprandial hyperglycemia. The proposed study shall be undertaken to assess the effect of almond supplementation on postprandial hyperglycemia in Asian Indians with prediabetes.

Clinical Trial Description

- Acute Phase Study: Randomized controlled cross over study design Number of arms: 2, almond and control, n=60 needed (30 in each arm) Subjects randomized to almonds arm are given a preload of 20 g of almonds 30 minutes prior to ingestion of 75 g of glucose, while those in the control arm do not have any food/almonds before OGTT. Blood samples are collected at (minutes): -30, 30, 0, 30, 60, 90 and 120. Cross over of these subjects is done and OGTT repeated in a similar manner. Assessment of blood glucose, serum insulin, glucagon, C-peptide, serum triglycerides, free fatty acids, DPP-IV, and GLP1 levels are done at these time points. - Sub-Acute Study: Three-day almond preload study monitored with CGMS, n=60 needed. All study participants undergoing OGTT are further studied with CGMS for three days each and then crossed over. Those in almonds arm continue to receive preload of almonds (20g almonds, 30 minutes before breakfast, lunch and dinner)for three days and then studied without almond preload after cross over. A washout period of 7 days separates cross-over period. o Chronic Phase Study: Ninety days almond preload study monitored with self-monitoring of blood glucose; n=60 needed. This is a randomized controlled parallel-arm study to evaluate the long-term effect of preload of almonds on hyperglycemia. Subjects fulfilling the inclusion/exclusion criteria are randomized to either the control arm or the almond arm. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
