Can lemon juice blunt blood glucose?

Yes, lemon juice can blunt blood glucose response. Andrew Huberman has noted that consuming a couple of tablespoons of lemon or lime juice before, during, or after meals high in carbohydrates can blunt the blood glucose spike. He confirmed this through his personal experiments using a continuous glucose monitor, observing a reduction in blood glucose response when consuming lemon juice with larger meals 1. Additionally, certain acidic substances, like lemon juice, can slightly alter the gut's pH, slowing down the absorption of sugars and thus helping to moderate blood glucose levels 2.
