It was always thought: white bread is more fattening than brown bread, toasted bread is lower in calories than white bread! However, they contain the same calories per serving!
What makes Brown bread or whole-wheat bread better than white bread is the fibre, vitamins, minerals and phytonutrients available in the outer layer of the grain. Fibre helps maintain a healthy digestive system and a stable blood sugar level leading to a feeling of satiety.
As for toasted bread, the process of toasting actually only removes the water from the bread and not the nutrients, so it doesn’t affect the calorie content of the piece of bread before toasting.
