White bread and other baked goods that use refined white flour are harmful to the liver because they are simple carbs that break down into sugar in your system. Blood glucose spikes and insulin levels rise in response. Shortly thereafter, you’ll experience a crash and be hungry again, having not provided your body any actual nutrition with the empty calories in bread. To avoid this vicious cycle, replace anything made with refined white flour with 100% whole grain versions. You’ll even out your blood glucose over a longer period and take in critical fiber plus B vitamins and essential minerals, as well.
