2. White Bread

White bread is made from refined flour that has been stripped of its fiber and nutrients. This makes it easy to digest and absorb, which can cause a rapid spike in your blood sugar levels after eating it. White bread also has a high glycemic index (GI), which is a measure of how quickly a food raises your blood sugar levels. Foods with a high GI are more likely to cause blood sugar spikes and crashes than foods with a low GI.

Instead of white bread, choose whole-grain bread that is rich in fiber and nutrients. Fiber can slow down the digestion and absorption of carbohydrates, which can help prevent blood sugar spikes and keep you feeling full longer. Whole grains also contain vitamins, minerals and antioxidants that can benefit your health.
