Millet porridge is known as "golden porridge". Because millet does not need to be refined, it preserves a lot of vitamins and inorganic salts, and the vitamin B1 in millet can reach several times that of rice. The content of inorganic salts in millet is also higher than that in rice. Millet porridge also has the effects of nourishing yin and blood, and sleeping with the stomach.

Sweet potato is rich in cellulose, mucin and rich nutrients, which can be said to be a good health care product for all ages. There are many ways to eat it, such as steaming, roasting, cooking, frying, cooking and cooking porridge. However, adding millet to sweet potato porridge is more beneficial to health. Although sweet potato is alkaline, it can neutralize the acidic metabolites of rice, noodles, meat and eggs, but if it is eaten too much and eaten improperly, it will also lead to abdominal distension due to too much cellulose. Millet is rich in nutrition, has the functions of strengthening the spleen and nourishing the stomach, and can inhibit the secretion of gastric acid. In Compendium of Materia Medica, Li Shizhen recorded that millet can cure "heat dysentery due to nausea". Therefore, in autumn and winter, when sweet potato porridge is popular, we might as well put some millet to inhibit the secretion of gastric acid, and correct the disadvantage that sweet potato is easy to lead to the increase of gastric acid secretion.
