Vinegar and Glycaemic Response
How the acetic acid in vinegar helps lower post-meal blood sugar spikes, supporting glycaemic control and appetite regulation.
Plain English
Patient-Friendly Explanation
Vinegar, especially apple cider vinegar, has been found to help lower blood sugar spikes after meals when taken before or with food. By moderating the glycaemic response, vinegar can help reduce insulin levels and cravings that often follow high-carbohydrate meals. While it is not a weight loss solution on its own, incorporating a small amount of vinegar into meals may support blood sugar control and appetite regulation.

Clinical Definition
Acetic acid, the active component of vinegar, inhibits disaccharidase enzymes in the small intestine and slows gastric emptying, reducing postprandial glucose excursion by 20-34% in controlled trials. This antiglycaemic effect is mediated partly through increased glucose uptake in skeletal muscle via AMPK pathway activation. A daily intake of 15-30 mL (1-2 tablespoons) diluted in water, consumed before or with carbohydrate-containing meals, has demonstrated consistent glycaemic benefit in both diabetic and non-diabetic populations.
Key Insight
Why It Matters
Better glycaemic control directly supports weight management by reducing post-meal insulin surges that promote fat storage and trigger hunger. This simple dietary strategy is affordable and readily available in Singapore, making it a practical recommendation for patients at Accord Medical seeking to improve their metabolic health.
