• Developing a Diet Sensor
It is well-known that an unhealthy diet is a top risk factor causing obesity and chronic diseases. Despite the importance of nutrition to health, scientists currently do not have user-friendly tools to conduct dietary assessment in real life. Months or years are often necessary to reverse a chronic condition by changing diet. Recently, Dr. Sun has been investigating a novel sensor system that conducts dietary assessment for macronutrients (carbohydrates, fats and proteins) automatically, leveraging on a coin-sized commercial sensor that measures interstitial glucose. This FDA-approved, low-cost and safety-proven sensor, called Continuous Glucose Monitor (CGM), has been used clinically for both diabetes management and research in heathy populations. Dr. Sun believes this convenient sensor can be converted to a powerful diet sensor using novel theoretical models and computational techniques. He has studied a unified food model which accumulates daily amounts of macronutrients ingested from real-world foods and beverages. Using this model, a novel technological framework will be established based on the theory of feedback dynamic control. If successful, Dr. Sun’s study may yield a powerful technology for a vast number of people who need to control diet-related diseases and conditions.
