Is bread good for you?

White bread doesn’t have many nutritional benefits, but you can get some from eating whole-grain bread. 

Eating whole grains has been linked with impressive health benefits, such as cancer prevention, lower risk of diabetes and obesity, and heart disease prevention. 

Whole grains are also high in fiber, which helps you stay full after eating, reducing the risk of weight gain and various other health conditions. 

Because of that, if you’re going to include bread in your diet, try going for whole-grain options.

Whole-wheat bread is much higher in several nutrients than white bread. For example, it contains more selenium and manganese, which are very essential for your health.

Many people choose to make their own sourdough starter, ensuring that the final product is as healthy as possible.
