The potential role of raw onions in the management of type 2 diabetes, particularly in relation to the established medication Metformin, has been examined by medical experts.
Endocrinologist Dr. Sanjay Kalra clarifies that while raw onions may offer complementary benefits, they cannot replace Metformin as a primary therapy for type 2 diabetes. Dr. Kalra emphasizes that Metformin is an established first-line treatment, with its mechanisms—including reducing liver glucose output, improving insulin sensitivity, and decreasing intestinal glucose absorption—being well-documented and supported by decades of evidence.
Research indicates that raw onions (Allium cepa) possess hypoglycemic properties. A clinical study demonstrated that consuming 100 grams of raw red onion significantly reduced fasting blood glucose levels in type 2 diabetic patients within a few hours. Furthermore, laboratory studies suggest that onion compounds can inhibit enzymes like α-amylase and α-glucosidase, which may slow carbohydrate digestion and mitigate post-meal glucose spikes.
However, the article highlights that the critical differences between raw onions and Metformin lie in their respective strength, consistency of effect, and the comprehensive evidence base supporting their use.
