What Foods Should You Avoid While Taking Metformin?

While taking metformin, avoid excessive alcohol consumption and limit high-glycemic foods like white bread, sugary drinks, and processed snacks. Alcohol increases the risk of lactic acidosis, a rare but serious side effect that occurs in about 3 per 100,000 patients annually. High-sugar foods can counteract metformin's blood sugar-lowering effects and cause glucose spikes. Also minimize refined carbohydrates, candy, and fruit juices which rapidly raise blood glucose levels. Instead, focus on fiber-rich vegetables, lean proteins, and complex carbohydrates that work synergistically with metformin to improve insulin sensitivity and maintain stable blood sugar throughout the day.
