Abstract: Introduction: Bread is a food full of flavors and nutrients and continues to be the basis of our daily diet. Aim: The aim of this
review was the investigation of bread’s usefulness in our daily dietary chain and health in general. Material-Method: Extensive review
of the recent literature was conducted in electronic databases (Medline, Scopus, and Google Scholar) through the Association of
Hellenic Academic Libraries (HEAL-Link) using the appropriate key words: bread, health, disease as well as a combination of them.
Results: Bread is an excellent source of complex carbohydrates that provide the body with the energy needed. Although bread is a basic
food of everyday human nutrition, it is implicated in a variety of situations that burden the human body, such as obesity. However, this
happens only when it is consumed in very large quantities and when it is part of an unbalanced diet. Conclusions: Bread, when is
consumed in balanced quantities can give the body plenty of nutrients essential for its good function.
Key words: Bread, health, disease.

The bread is a rich secret source of sodium. A slice of white, wheat bread (28 g) contains 134 mg of sodium (Na),
while a slice of rye bread (28.35 g) contains 171 mg of sodium (Na). By reducing salt content from the bread,
