Is adding baking powder to bread harmful to health?

This question needs to be answered from two aspects. There are two kinds of baking powder: one is baking soda, which is sodium bicarbonate (NaHCO? )。 From the molecular formula, we know that its ingredients are non-toxic. However, for people with heavy mouths, eating baking soda will increase the intake of sodium ions, but the addition of baking powder is not high, which has little effect on the intake of sodium ions. Sodium is accurately calculated in the American food composition table, but it is not explicitly emphasized in China. Another baking powder, alum or alum preparation, potassium aluminum sulfate dodecahydrate (alum) is added. This kind of baking powder has strong foaming ability, and the food made is soft and delicious. Many steamed bun shops, bakeries, fried dough sticks shops and so on use this baking powder containing alum. Alum contains heavy metal aluminum, which is very toxic to human body and can be deposited on bones and brains, causing growth retardation in children, mental retardation, joint pain in adults, memory loss in the elderly, and even inducing Alzheimer's disease. In fact, there are many symptoms of aluminum poisoning. You just need to know that aluminum is toxic, it will precipitate and do great harm. Therefore, it is suggested to use yeast powder to make fermented food at home. Yeast belongs to fungi (such as lactic acid bacteria and mushrooms), which is not only nontoxic, but also can improve flour and increase nutrition (Angel is recommended). If it is too late to ferment, please use baking powder without aluminum formula (Angie is still recommended). If you like bread, you can buy a toaster, which is on sale now. I suggest you don't use baking powder without aluminum. As for the fried dough sticks and oil cakes outside, it is best to buy less. Do it yourself and have plenty of food and clothing. In the past, food and clothing were greater than the sky, but now health is greater than the sky. The last set of popular words: cherish life and stay away from alum.
