bread contains vitamin B1 and B3, calcium and iron, starchy carbohydrates and dietary fibre
wheat flour adds bulk to the bread, creates different flavours, absorbs water to make a dough, has a high protein content, and contains nutrients such as starchy carbohydrates, protein and fortified vitamins and minerals
liquid in bread helps to create the right conditions for yeast to grow (37 degrees), when dough is baked the moisture turns to steam and binds everything together
salt in bread helps with gluten formation, improved the flavour of bread, however too much can stop yeast fermenting
yeast is needed for fermentation and to form correctly it needs 37 degrees, moisture, sugar and time
