Vitamins and other minerals

Bread contains a wide range of different vitamins and minerals including potassium, magnesium, phosphorous, copper, zinc, chlorine, manganese, iodine, B vitamins and biotin. Heres why the human body needs them:
Potassium Potassium helps balance the pH of your body, and is important for muscle growth and healthy nervous system and brain function.
Magnesium This is necessary for strong bones, the release of energy from food, and the transmission of nerve impulses and muscular movements.
Phosphorous required for maintaining body functions, the production of energy, and it works alongside calcium and magnesium, to maintain healthy teeth and bones.
Copper This is required for when your body metabolises energy.
Zinc This helps to develop a healthy immune system and is necessary for growth and development, including that of the reproductive system.
Chlorine This helps regulate water in the body.
Manganese This helps in the bodys metabolic processes. It also aids calcium absorption, helps to regulate blood sugar levels and helps to regulate both the thyroid and sex hormones.
Iodine This is necessary for regulating the thyroid gland.
B vitamins These help the human body to metabolise energy. They are also necessary for a healthy nervous and digestive system.
Biotin This is necessary for energy release from fats.
