Also worth remembering that ‘carbs’ will often increase blood glucose more than ‘sugar’. Sucrose (sugar) is only 50% glucose. The rest is fructose. Fructose doesn’t actually raise your blood glucose if it’s already elevated - it is metabolised almost straight away into fat by the liver, and contributes directly to fatty liver and insulin resistance. Fructose is public enemy number one for causing and exasperating insulin resistance, but when it comes to raised blood glucose, flours and starches are generally worse.
