In life, some people often put some alkali in the porridge when cooking millet porridge, especially the chefs in the dining hall like to do so. On the one hand, the picture is cooked quickly, on the other hand, the porridge cooked after adding alkali is more sticky and delicious, and the taste is good. However, they don't know that this will destroy the most precious nutrients in rice (rice and millet), such as vitamin B 1 and vitamin B2. Moreover, because vitamin B 1 is called a mental nutrient, it has a very important influence on nervous tissue and mental state, and when it is insufficient, it will cause symptoms such as fatigue, forgetfulness and anxiety. Therefore, it is necessary not to add alkali when cooking millet porridge.
