the goal of this Randomized controlled cross over trial is to compare the effects of meal sequences VPF meal vs. SMM on the incremental area under the curve of postprandial glucose response among healthy adults in the UAE. the main question it aims to answer is what is the effect of meal sequence of vegetable and protein first followed by carbohydrates (VPF) compared to a standard mixed meal (SMM) on the postprandial glucose level and insulin response among healthy adults in the UAE. Participants will consume two is caloric test meals in random order (SMM and VPF meal sequences) separated by a 7-10-day washout period then blood sample will be collected at fasting ,30min,60min and 120mon for glucose and insulin and hunger ration will be done as well .Researchers will compare the effect of the two meals on postprandial blood glucose, insuline and hunger rating.
