A1-Free vs. Conventional Milk Metabolic Response Study

This study will examine how different types of milk affect blood sugar and insulin responses after eating. Specifically, the study compares milk that contains only A2 beta-casein protein (A1-free milk) to conventional milk, which contains both A1 and A2 proteins. Participants will complete four study visits in which they will consume different milk-based beverages. These include lactose-containing milk and lactose-free milk followed by a lactose drink given later. Blood samples will be collected over several hours to measure glucose and insulin responses. Breath tests and questionnaires will also be used to assess digestion and gastrointestinal symptoms. The goal of this study is to determine whether milk protein type influences metabolic responses and whether consuming lactose-free milk affects how the body processes lactose when it is consumed later.

Advancing Precision Nutrition: Wearable Technology for Noninvasive Insulin Monitoring

Noninvasively monitoring insulin is crucial for advancing precision nutrition and promoting healthy living by enabling a deeper understanding of individual metabolic responses to dietary intake. Insulin is a key regulator of blood sugar and energy metabolism, and its dysregulation is linked to conditions such as diabetes, obesity, and metabolic syndrome. By noninvasively tracking insulin levels, individuals can gain real-time insights into how their body processes different foods, allowing for the personalization of diets to optimize metabolic health, manage weight, and reduce disease risk. This approach also empowers proactive lifestyle adjustments to maintain insulin sensitivity, improve glycemic control, and enhance overall well-being. Decentralized insulin quantification in biofluids, including saliva and serum, based on lateral flow assay or electrochemical sensor has been reported. However, these approaches have poor sensitivity and fail to quantify insulin with a high temporal resolution.
