The main raw materials of bread are flour and yeast, followed by sugar and oil, plus other auxiliary materials. The main raw materials are flour and yeast. Yeast produces B vitamins when fermenting flour. Well, from here, we can see that bread should be a relatively healthy food, which can not only satisfy the stomach, but also supplement B vitamins well, and the amount of sugar and oil is far less than that of biscuits and bread.
There are two main types of biscuits. The first kind of raw materials are flour, oil, sugar, eggs, milk powder and milk, plus some auxiliary materials (such as chocolate). The crispness of these biscuits mainly comes from oil (mainly butter), so the main components of these biscuits are flour, oil and sugar, and other raw materials are relatively few. It can be seen from here that these biscuits are high in energy and have few kinds of nutrients, which obviously do not belong to too healthy. Another biscuit, besides the same raw materials as the previous biscuit, its brittleness depends on baking powder and baking soda, which belongs to the category of additives. Generally, if you do it yourself, the amount added will not be too much, and the problem is not big. Things bought outside are out of control. So this kind of biscuit is not as healthy as the previous one.
